ITS Maintenance Standards

1. INTRODUCTION

1.1. PUBLICATION PURPOSE The purpose of this publication is to provide guidance to those responsible for the maintenance of

Intelligent Transportation Systems (ITS) devices throughout the Commonwealth. With the continued

deployment of ITS devices, maintenance is an increasing issue. In order to provide ITS practitioners a

consistent framework for maintaining ITS devices and systems, ITS maintenance standards must be

developed and utilized. This document will detail specific baseline maintenance activities for ITS devices

and systems.

This publication will present standard maintenance practices for the following:

Dynamic Message Signs (DMS)

Closed Circuit Television (CCTV) Cameras

Highway Advisory Radio (HAR)

o HAR Transmitter

o HAR Flashing Beacon

Vehicle Detectors

o Microwave Vehicle Detector

o RFID Transponder based Vehicle Detector

RWIS (required coordination with BOMO)

Travel time systems

Over-height truck detection

Curve warning system

Field communications equipment

Fixed Anti-Icing Spray Technology (FAST or MicroFAST) Systems

Crash Avoidance Systems

Traffic Management Centers

o Video Walls and associated Video Equipment

o Communications Equipment

o Uninterruptible Power Supplies (UPS)

Ramp Metering Systems

High Occupancy Vehicle Systems

Lane Control Signing

Inadequate maintenance of ITS devices can lead to inaccurate or deficient operation. These issues often

lead to safety concerns, increased response maintenance costs, and decreased functionality; which is

why it is essential that consistent preventative, response, and emergency maintenance be provided

throughout the Commonwealth. The benefits of a properly maintained ITS system include reduced

driver delays, faster incident response, reduced secondary accidents, reduced fuel consumption, and

increased driver safety. Proper maintenance will also help to extend the service life of the device.

1.2. ITS Plans

1.2.1. Site Plans

The ITS site plan is a useful tool when evaluating the condition of an ITS device. The ITS site plan contains information regarding the locations of equipment, electrical service, communications, conduit, guiderail, and any other relevant site characteristics. The site plan may also contain important notes regarding the device. A copy of the ITS Site Plan should be kept in the District office as well as at the device (inside the cabinet).

Figure 1: ITS Site Plan

1.2.2. System block diagrams

The system block diagram is used to schematically display the manner in which the device communicates with the traffic management center and with other devices. This may be useful when diagnosing a communications issue, as it identifies the path that the communications signal follows to the traffic management center. A copy of the system block diagram should be kept in the District office as well as at the device (inside the cabinet).

Figure 2: System Block Diagram

1.2.3. Electrical Details/Wiring Diagram

The electrical details/wiring diagram indicate how the ITS device receives electrical power. This is typically presented schematically and may be useful when diagnosing an electrical issue, as it identifies the manner in which the ITS device receives electrical power. A copy of the electrical details/wiring diagram should be kept in the District office as well as at the device (inside the cabinet).

2. ESTABLISHING AN ITS MAINTENANCE PROGRAM In order to have an efficient and functional ITS system, it is absolutely necessary to have a well executed

7

ITS maintenance program. A failure to properly maintain an ITS system will result in poor operation, which affects the Department’s ability to safely and effectively manage their roadways. It is important to remember that the ITS system will undoubtedly change over time. As the system evolves, there will be changes to the concepts of operations, requirements, and the stakeholders who generated the requirements. In order for the ITS maintenance program to be successful in this environment, it will be necessary to maintain flexibility and a good understanding of priorities for the maintenance concepts and requirements.

2.1. Budgeting After an ITS system is installed and tested, the Department becomes responsible for the maintenance costs required to keep the system operational. It is important that the Department provide an appropriate budget for preventative maintenance, response/emergency maintenance, and spare parts. Preventative maintenance costs can escalate over time as equipment wears out and eventually needs to be replaced. Emergency repair costs will increase if proper preventative maintenance is not provided. Typical annual maintenance costs depend on several factors such as the age and complexity of the ITS system. However, most districts determine their ITS maintenance budget by reviewing previous experiences and budgets. At times, a device may fail early in its service life. If this is the case, the device may still be covered under a warranty. This warranty may cover the repair costs. The District ITS Manager must consider the current warranties when developing an ITS budget. Table 3 presents sample life expectancies for various ITS device components. This data can be used to assist in the development of an estimated ITS maintenance budget. These lifetimes are typical, and should represent the majority of installations; however some installations may have significantly shorter (or longer) lifetimes due to a variety of factors, some of which may be outside of the Department’s control. Table 3: Sample Life Expectancies of ITS Device Components (FHWA)

Wireless Communications (high usage) 20

When developing an ITS maintenance budget, it is important to understand the age and condition of the current ITS inventory. As an ITS device reaches the end of its service life, it approaches a point of diminishing returns where maintenance costs begin to exceed the annualized replacement costs. Figure 5 shows a generic representation of preventative maintenance costs per year versus the cost of replacement, annualized over the expected device lifespan. The “break even point” (or lifetime) represents the point at which the preventative maintenance costs of a device are the same as the annualized replacement costs. Once a device has passed this “break even point” it is uneconomical to

8

continue maintenance of the deteriorating device. The “break even point” is not easily calculated and requires a comprehensive collection of maintenance costs.

Figure 5: Preventative Maintenance versus Annualized Maintenance Costs. Source: Guidelines for Transportation Management Systems Maintenance Concept and Plans FHWA

2.2. Scheduling As will be discussed in Section 3.3, preventative maintenance should be scheduled every 6 months (unless the manufacturer suggests more frequently), prior to and after the winter season of each year. However, response and emergency maintenance can occur at any time, so the ITS maintenance contractor needs to have adequate personnel in place to respond to these situations.

2.3. Training While ITS maintenance will be primarily performed by contractors throughout the Department, it is still beneficial to have a capable and well trained ITS staff. This may be difficult, as there are no common training venues for ITS maintenance; however vendor training is typically available and may be included in the installation contract. District ITS staff should receive any available training in order to allow the Districts to supplement the ITS maintenance contract per their capabilities; this may include assigning response/preventative maintenance activities to in-house staff when available. The District ITS manager should ensure that the ITS staff be trained on new updates and equipment.

2.4. Documentation A record must be kept of all maintenance activities performed on ITS devices. This record must be logged in accordance with Chapter 4.

2.5. Coordination Coordination of maintenance and repair activities is important for any District with ITS devices, and becomes more significant as the number of ITS devices increases. Maintenance activities must be coordinated among District ITS staff and the maintenance provider such that it is performed in a timely

9

and cost-effective manner. ITS maintenance can be initiated in many ways, such as a call-in from agency staff or the public. Once reported, the ITS staff member who receives the notification will open a Maintenance Need Report (Appendix D) and assign the response to either the contractor or Department staff. Once the responder has arrived on site and corrected the issue, the ITS Staff must verify correct operation (where possible). The responder must submit a completed Field Maintenance Report Form (Appendix E), which will be combined with the completed Maintenance Need Report (digitally) and submitted to the ITS Maintenance Repository (Section 4.2). Figure 6 shows the maintenance process described above.

Figure 6: ITS Maintenance Flow Chart

3. ITS MAINTENANCE CLASSIFICATIONS The following maintenance classifications will be used for all ITS maintenance throughout the Commonwealth:

Response Maintenance

Emergency Maintenance

Preventative Maintenance

These classifications are described in the following sections (Sections 3.1-3.3).

3.1. Response Maintenance Response maintenance occurs when the malfunction or damage is not considered to be an emergency. This is often the case for failed components and other minor issues that do not prevent normal operation of the device. The determination if a repair requires response maintenance is at the discretion of the District ITS Manager and should be based on the severity of the damage/malfunction, availability of alternate devices, and location of device. Response maintenance activities include the following actions, and must be performed within the timelines described below:

1. Responder receives notification: This is the point in time that the Department notifies the responder of an issue that requires response maintenance.

10

2. Responder arrives at site and diagnoses issue: The responder must arrive at the site and diagnose the issue as soon as possible but within 48-hours of receiving notification of the issue, unless otherwise approved by the Department.

3. Perform repairs: The responder must perform the repairs as soon as possible, but within four days (96 hours) of receiving notification, unless otherwise approved by the Department. The repairs will be considered complete once the device/equipment has been restored to normal operation.

4. Log activity: This includes submission of the Field Maintenance Report Form (Appendix E) by the responder, to the District ITS Manager as described in Chapter 4.

The repair time requirement may be waived / extended at the discretion of the Department if there are delays that are not caused by the maintenance provider. These delays include such issues as lack of spare parts, vendor delays, utility company non-responsiveness, site conditions, and legacy products. In order for the repair time requirement to be waived or extended, the maintenance provider must submit a completed Repair Time Extension Request Form (Appendix F) to the Department before the 96-hour repair time has passed.

3.1.1. List of typical items

Typical response maintenance activities may include:

Replace failed LED panel

Clearing of obstructions (snow, dirt, etc.)

Cleaning device (CCTV dome, DMS face)

Rodent removal

Repair/replace a malfunctioning component

Failed power supply

Cracked CCTV dome

Other non-emergency repairs

3.2. Emergency Maintenance Emergency maintenance occurs as a response to any damage and/or malfunction that requires immediate repair. Emergency maintenance is typically necessary when an ITS device is no longer able to operate. This is often due to forces of nature, vehicle collision, vandalism, fire, device failure, or other unexpected issues. The determination if a repair requires emergency maintenance is at the discretion of the District ITS Manager and should be based on the severity of the damage/malfunction, availability of alternate devices, and location of device. These damages need to be repaired as soon as possible, and it is recommended that emergency responders arrive to the site within 4 hours of notification. When damages are severe or involve a vehicular accident, the emergency responder should provide the Department with photographs in order to document the extent of the damages. An appropriate length for repair may be within 24-hours of notification (unless otherwise approved by the Department; criteria affecting the repair time may include availability of spare parts, site conditions, location, etc.). Emergency maintenance activities include the following actions, and must be performed within the timelines described below:

1. Responder receives notification: This is the point in time that the Department notifies the responder of an issue that requires emergency maintenance.

11

2. Responder arrives at site and diagnoses issue: The responder must arrive at the site and diagnose the issue as soon as possible but within 4 hours of receiving notification of the issue, unless otherwise approved by the Department.

3. Perform repairs: The responder must perform the repairs as soon as possible, but within one day (24 hours) of receiving notification, unless otherwise approved by the Department. The repairs will be considered complete once the device/equipment has been restored to normal operation.

4. Log activity: This includes submission of the Field Maintenance Report Form (Appendix E) by the responder, to the District ITS Manager as described in Chapter 4.

The repair time requirement may be waived / extended at the discretion of the Department if there are delays that are not caused by the maintenance provider. These delays include such issues as lack of spare parts, vendor delays, utility company non-responsiveness, site conditions, and legacy products. In order for the repair time requirement to be waived or extended, the maintenance provider must submit a completed Repair Time Extension Request Form (Appendix F) to the Department before the 24-hour repair time has passed.

3.2.1. Emergency Deployment

In the event that normal operation cannot be restored within 24 hours, it may be necessary to deploy a temporary device as an interim solution. The District ITS Manager will determine if it is necessary to deploy an emergency device. . Upon receipt of the Repair Time Extension Request Form (from the responder), the District ITS Manager may require that a temporary device be installed until repairs to the existing device can be made. The District ITS Manager should consider the location of the device, availability of alternative devices, site conditions, and other factors when determining if an emergency/temporary device is required. If it is determined that an emergency/temporary device is required, the operator completing the report must indicate this on the PennDOT Maintenance Need Report Form and instruct the responder as necessary.

3.2.2. List of typical items

Typical emergency maintenance activities may include:

Repair to damaged structures (with BQAD oversight)

Deployment of temporary ITS devices

Repair/replace damaged components

Restoring electrical service

Restoring communications

Removal of obstructions

Repair of damages caused by erosion

3.3. Preventative Maintenance Preventative maintenance is the routine care and service for the purpose of maintaining equipment in satisfactory operating condition by providing for systematic inspection, detection, and correction of failures either before they occur or before they develop into major defects. It also includes the periodic repair and replacement of components as needed to properly maintain the device. This includes such activities as filter cleaning or changing, cleaning CCTV domes or DMS face plates, light bulb replacements, faulty surge arrestors, rodent removal, and sealing conduits. Preventative maintenance is to be completed a minimum of twice per year for each device (unless the manufacturer suggests more), prior to and especially after the winter season of each year; the District ITS manager may request

12

additional preventative maintenance as needed. In order to determine if an ITS device requires more frequent preventative maintenance visits, the District ITS Manager should consider the age and history of the device, device type, location of device with respect to roadway, and other possible factors. Once a District ITS Managers identifies those devices that require maintenance more than twice a year, they should include the necessary maintenance times in a schedule attached to the contract (see Chapter 5 – Contracting for additional details). Figure 7 shows the preventative maintenance process, which includes; inspection, minor repairs, troubleshooting, and reporting.

Figure 7: Preventative Maintenance Process. Source: Guidelines for Transportation Management Systems Maintenance Concept and Plans FHWA

As illustrated in Figure 7, the preventative maintenance process begins with the routine checks that can

be found in the Preventative Maintenance Guides in Appendix C. The ITS equipment passes the check if

all items are recorded as being in Excellent or Good condition. If an item is rated as being in Fair or Poor

condition, then the degree of maintenance must be determined in the field. If the issue can easily be

resolved (minor issue) then the responder is to perform the minor maintenance operation and resolve

the issue. If a major repair is required (not easily repaired, new parts required, etc.), then the responder

must determine the nature of the issue, and report it in the Preventative Maintenance Report Form. The

District ITS manager will then advise the responder on the proper response.

13

3.3.1. DMS

Preventative maintenance and inspection must be performed a minimum of twice per year for each

DMS. This inspection must include the DMS, control cabinet, structure, electrical service,

communications, conduit, and junction boxes. Appendix C contains detailed Preventative Maintenance

Guides for DMS and ITS Structures that are to be used for all preventative maintenance visits. This guide

must be completed in the field by the responder, and returned to the District ITS manager.

3.3.2. CCTV


CCTV. This inspection must include the Camera assembly, control cabinet, structure, electrical service,

communications, conduit, and junction boxes. Appendix C contains detailed Preventative Maintenance

Guides for CCTV and ITS Structures that are to be used for all preventative maintenance visits. This guide

must be completed in the field by the responder, and returned to the District ITS manager.

3.3.3. HAR

Preventative maintenance and inspection must be performed a minimum of twice per year for each HAR

Transmitter and Flashing Beacon. This inspection must include the HAR transmitter, flashing beacon

assembly, control cabinets, structures, electrical service, communications, conduit, and junction boxes.

Appendix C contains detailed Preventative Maintenance Guides for HAR Transmitters, HAR Flashing

Beacons, and ITS Structures that are to be used for all preventative maintenance visits.

3.3.4. Vehicle Detectors


vehicle detector. This inspection must include the detector, control cabinets, structures, electrical

service, communications, conduit, and junction boxes. Appendix C contains detailed Preventative

Maintenance Guides for Microwave Vehicle Detectors (MVD), RFID Transponder based Vehicle

Detectors, and ITS Structures that are to be used for all preventative maintenance visits. This guide must

be completed in the field by the responder, and returned to the District ITS manager.

3.3.5. Other ITS Devices

While the devices discussed in Sections 3.3.1-3.3.4 account for much of the Department’s ITS inventory,

there are a number of other devices and systems that are critical to the success of the ITS network;

including:


Travel time systems








14






The maintenance of these devices must be held to the same standards as those discussed in Sections

3.1-3.3, and must be included in the ITS maintenance contract (unless covered elsewhere). However, at

this time Preventative Maintenance Guides have only been developed for DMS, CCTV, HAR, and vehicle

detectors. While there are currently no standardized maintenance procedures for these devices, there

are non-standardized maintenance procedures that the Districts have used in the past. At this time, the

maintenance of these devices should continue to follow current procedures.

In order to maintain a consistent and accurate record of ITS maintenance, all maintenance activities

must be logged in the same fashion. For this reason, a blank preventative maintenance guide (including

checklist and report) can be found in Appendix C. This guide must be completed for all ITS maintenance

activities.

Traffic signals are typically owned and maintained by the Municipality, however in some cases they are

owned and maintained by the District. As there are very few occurrences of this, it is not typical to have

a separate signal maintenance contact for a small number of signals. Therefore, any District owned

traffic signals should be included in the ITS maintenance contract, and maintained as described in Pub

191.

Since BOMO utilizes the RWIS data for several applications, special coordination will be required

between the regional/district maintenance contract managers and BOMO. This special coordination is

due to BOMO’s reliance on RWIS data to perform functions such as road salting; special coordination

will help to prevent untimely shutdowns. Additionally, BOMO may be the first to identify an issue with

an RWIS device and can notify the maintenance contract managers.

It is also important that all TMC systems and components are maintained, and kept in good working

condition. While these may not be considered ITS devices, they are critical to the success of the ITS

system and must be maintained accordingly. As the TMC components are not typically exposed to the

elements, a periodic visual inspection is typically adequate to ensure that wires/cables are not frayed or

damaged, and that all connections are secure. In the event that a TMC component needs to be repaired

or replaced, an Emergency or Response maintenance request will be issued to the maintenance

provider.

4. MAINTENANCE TRACKING Maintenance tracking is a critical component of the ITS maintenance program, and must be done in a

15

consistent and organized manner throughout the Commonwealth. As ITS maintenance contracts will be

executed regionally (to be discussed in Section 5.1.2.2), it is essential that all districts have access to

maintenance records throughout the region, and that these records be presented in a consistent

manner in order to avoid confusion. To accomplish these tasks a set of standardized forms and a

centralized data repository have been created.

4.1. Forms The following forms have been created in order to provide the Department with a consistent and

organized means of tracking ITS maintenance throughout the Commonwealth.

Preventative Maintenance Guides (Appendix C)

o Dynamic Message Sign (DMS)

o Closed Circuit Television Camera (CCTV)

o Highway Advisory Radio (HAR) Transmitter

o Highway Advisory Radio (HAR) Flashing Beacon

o Microwave Vehicle Detectors (MVD)

o RFID Transponder Based Vehicle Detectors (RTVD)

o Other ITS devices

PennDOT Maintenance Need Report Form (Appendix D)

Field Maintenance Report Form (Appendix E)

Repair Time Extension Request Form (Appendix F)

The responder must complete and submit a Field Maintenance Report Form to the District whenever

emergency or response maintenance work is performed. Upon completion of all preventative

maintenance work, it is required that the responder submit the completed preventative maintenance

reports and checklists for each device within 1 week (7 days) of the preventative maintenance visit. A

Repair Time Extension Request Form must be submitted whenever the maintenance provider requests

that the District waive or extend the repair time requirement.

These forms are to be used to document all Response, Emergency, and Preventative maintenance as

described in Sections 3.1 to 3.3 and are to be documented in the ITS Maintenance Repository as

described in Section 4.2.

4.2. ITS Maintenance Repository The ITS Maintenance Repository has been created on the PennDOT P-drive (also accessible through the

PennDOT Portal) in order to allow all districts to have access to the maintenance records for any ITS

device. This directory, along with the standardized maintenance forms located in the appendices of this

document, was created to allow the Districts to track all maintenance activities and to keep an accurate

record of work performed. The ITS Maintenance Repository is a directory through which the District ITS

manager can quickly access the maintenance history of any device. This information is essential to

scheduling and budgeting of future maintenance activities.

16

All forms related to a single maintenance issue are to be combined in a digital format (PDF is preferred)

and saved in the ITS Maintenance Repository. It is the responsibility of the District ITS Manager to

ensure that these records are maintained in the ITS Maintenance Repository.

Record maintenance activities in the following manner:

1. Obtain maintenance report from contractor or in-house personnel

2. Combine with Maintenance Need Report (and Time Extension Request Form when necessary)

and convert to digital copy

3. Name the digital file using the following naming convention

a. Date of Report_StatewideID.XXX

i. Example: 20110125_DMS-01-001.pdf

4. Save a copy of the file in the proper folder in the ITS Maintenance Repository

a. ITS Maintenance Repository is located at: P:\Traffic Operations\ITS Maintenance

Repository

i. Place file in the appropriate folder (District\Maintenance Type

1. If the appropriate folder does not exist, please contact BHSTE.

An example file location for an Emergency Maintenance issue reported on 01/25/11 for DMS1 in District

1-0 will be as follows:

P:\Traffic Operations\ITS Maintenance Repository\District 1-0\ Emergency-Response\20110125_DMS-

01-001.pdf

5. CONTRACTING There are several aspects needed to implement a successful ITS maintenance program. The most

important of which is the execution of a maintenance contract with a private contractor in order to aid

the Districts with maintenance issues. The following sections identify elements and special provisions

that should be included in an ITS maintenance contract.

5.1. Contract Elements

5.1.1. Staffing

District ITS staff are often the most efficient and cost effective resources available for performing the

initial diagnosis of any maintenance issue. However, each District has varying levels of in-house

expertise, staffing, equipment, and inventory of parts necessary to maintain the ITS devices. In order to

enhance the Districts’ ability to maintain the devices, regional maintenance contracts with private

contractors should be executed. Contractors are able to respond to emergency calls on a 24/7 basis and

are typically more experienced with ITS devices. When a maintenance issue arises, the District ITS

manager should consider the in-house capabilities, along with the nature of the issue while determining

the proper course of action.

Districts should strive to keep a well-trained and knowledgeable maintenance staff to ensure that

maintenance contracts are effectively managed, and to supplement the maintenance contract by

17

performing minor device maintenance that is not critical in nature (replacing pixel boards, changing

filters, etc.). In order to effectively supplement the ITS maintenance contracts, District ITS staff should

receive any available training. The District ITS manager should ensure that the ITS staff be trained on

new updates and equipment.

5.1.2. Contract Details

5.1.2.1. Contracting Mechanism

At this time, the ITS maintenance provider should be contracted via the low-bid process through ECMS.

The maintenance contract should be a regional contract with a contract length of 2 or 3 years, require

qualifications, and have a clear scope of work.

5.1.2.2. Geographic Coverage

As the Department’s ITS network has continued to evolve and develop, ITS management has extended

beyond District boundaries and, in many cases, is regional in nature. Due to this regional nature and the

Department’s continued focus on developing regional ITS management, regional maintenance contracts

are recommended as the most effective contract model. In order for a regional contract to be

successful, there must be close coordination and cooperation between the Districts involved. These

regional contracts will allow larger “lead” districts to support nearby “developing” districts, while also

helping to promote consistency within the regions. Two potential regional alignments could be by an

operational alignment or an alignment based on equipment type. The operational regions could be

based on the existing RTMC configurations, while the equipment type regions would include Districts

with similar field equipment.

5.1.2.3. Qualifications

In order to ensure that only contractors qualified in ITS maintenance are accepted, the Department

should utilize the established prequalification Work Class Codes to ensure qualified respondents. The

proper use of Work Class Codes will assist in delivering qualified contractors to perform ITS

maintenance. It is not a requirement that the prime contractor has all of the codes, but the prime

contractor must be prequalified for greater than 50% of the work that is associated with the project, and

the contractor’s team should satisfy all necessary qualifications to perform the maintenance service

request.

Recommended Work Class Codes are as follows:

P1 CCTV, RWIS, Automated Deicing Systems

P2 Highway Advisory Radio Systems (HAR)

P3 Dynamic Message Signs (DMS)

P4 Integrated Communication Systems

P5 Level 1 System Integrators (Hardware)

18

P6 Level 2 System Integrators (Software)

P7 Level 3 System Integrators (Hard/Software)

P8 Highway/Sign Lighting Electrical

Q Maintenance and Protection of Traffic

In order to ensure that all contractor personnel assigned to the maintenance contract are qualified, the

Department may require that the contractor submit the resumes of all technicians and field personnel.

The Department may then reserve the right to deny any unqualified technician from working on the ITS

maintenance contract if the Department feels that the individual is qualified to perform the work. If the

successful bidder cannot furnish qualified technicians, the Department may terminate the contract.

5.1.2.4. Devices and Systems

There are numerous ITS devices and systems deployed throughout the Commonwealth. Some systems

may only be installed within one District/Region. Regardless, all ITS devices and components should be

included under each ITS maintenance contract. The contract should include preventative maintenance,

response maintenance, and emergency maintenance of components of the ITS network, including all

center-to-field communications equipment. As many ITS maintenance needs involve the

communications network; this work must be included in the ITS maintenance contract. It is necessary to

include Transportation Management Center (TMC) maintenance in this contract as well. An ITS

maintenance contract should include (but not be limited to) the following typical ITS components:


Closed Circuit Television (CCTV) Cameras

Highway Advisory Radio (HAR)

o HAR Transmitter

o HAR Flashing Beacon

Vehicle Detectors

o Microwave Vehicle Detector

o RFID Transponder based Vehicle Detector


Travel time systems










19




A table that provides information on each ITS device should be provided as part of the contract. This

table should include all devices the maintenance contractor will be responsible for maintaining.

Information included in the table should be District/County, Device Type, Device Number, Location (SR,

Segment/Offset), GPS coordinates, and Location Name. Provisions should be included for additional

devices that may be deployed during the maintenance period.

5.1.2.5. Spare Parts

In order for response maintenance and emergency repairs to be performed within the time parameters,

an inventory of spare parts is recommended. The supply of spare parts can be one of the primary delays

in returning devices to their normal operation. It is recommended that the contractor maintain,

supplement, and utilize a spare parts supply held, owned, and managed by the Department. The

inventory should be sufficient to allow for prompt response maintenance but should be limited to an

amount that will not result in an “outdated” inventory of equipment. An appropriate inventory may be

10-20 percent of the key components by ITS device type and make. These components may include:

Controller fans, sensors, and power supplies by device/brand

Modems for all devices

Spare fiber and patch cords

Pixel boards for DMS

HAR antennas and transmitter modules

CCTV units by brand

Encoders/decoders for CCTV

Center to field communications equipment

Communications Cables

Beacon Paging Units

The contents and quantities maintained in the ITS inventory are at the discretion of the District ITS

Manager. The District ITS manager will determine the types and quantities of parts to be held in the

inventory. It is the responsibility of the contractor to replace any used part with a replacement part of

equal or greater quality.

5.1.2.6. Attachments

Several attachments should be included as part of the contract. Attachments should include a device

table, schedule for maintenance, and list of spare parts.

The device table should include all devices for which the contractor will be expected to provide

maintenance and include at a minimum the following information:

Type of device

District ID number

Statewide ID number

20

Location Name

SR number

Segment/Offset

Mile Marker (if applicable)

Status

Warranty – Those devices still under warranty and their corresponding expiration dates should

be identified.

The schedule should include time periods when preventative maintenance is expected to occur. Within

the schedule, those devices that would need additional preventative maintenance visits should be

identified.

As discussed in Section 5.1.2.5, the Districts should have an inventory of spare parts available for the

maintenance contractor to use for repairs. A table of available spare parts should be included in the

contract.

5.2. Contract Specifications

5.2.1. Standard Specifications

Each contract should include standard Department specifications. The standard specifications should be

both general in nature and region specific. For example, special provisions that deals with air pollution

control per local County health departments would likely need to be included. In addition, there may be

the need to provide changes to certain standard specifications. Each region should identify the

necessary changes and include these modified specifications in the contract.

5.2.2. Special Provisions

The details of the contract will be established in the contract special provisions. Special provisions

should be developed for the Preventative Maintenance, Response Maintenance and Emergency

Maintenance of each ITS device. For DMS, CCTV, HAR Transmitter, HAR Flashing Beacons, and

Microwave and RFID detectors, the special provision can point to the Preventative Maintenance Guides

for expected work details. For other specialized ITS devices, the District should identify the preventative

maintenance expected in the special provision. Appendix G includes sample specifications for the

preventative maintenance, response maintenance and emergency maintenance of ITS devices. In

addition to the maintenance special provisions, a special provision should be included for the

Maintenance and Protection of Traffic and any detailed device special provisions that would be needed

for obtaining parts.

Appendix B-Glossary

Department – Term used to reference the Pennsylvania Department of Transportation

Detector – A device for indicating the presence of a vehicle or pedestrian.

Emergency Maintenance – Repair of a malfunction or damage that is urgent in nature (vehicle collision

with device, vandalism, weather damage, etc.). The determination if a repair is “urgent in nature” is at

the discretion of the District ITS Manager and should be based on the severity of the

damage/malfunction, availability of alternate devices, and location of device.

Mean Response Time – The average response time per device type (CCTV, DMS, etc.). Upon

notifications, this is the time it takes for the contractor to arrive at the site and diagnose the problem.

Maintenance Provider – The party responsible for providing a maintenance service. This term may be

used to refer to Department personnel or a private contractor.

Preventative Maintenance – Routine care and service for the purpose of maintaining equipment in

satisfactory operating condition by providing for systematic inspection, detection, and correction of

incipient failures either before they occur or before they develop into major defects. (replacing filters,

repair loose/frayed wires, checking for rust, etc.)

Response Maintenance – Repair of a malfunction or damage that is not urgent in nature (device still

functions, device is not frequently used, etc.). The determination if a repair is “urgent in nature” is at the

discretion of the District ITS Manager and should be based on the severity of the damage/malfunction,

availability of alternate devices, and location of device.

Response Time – The time that it takes a responder to arrive at the requested site; beginning when the

contractor is notified of the request, and ending when the contractor arrives at the requested site.

Uptime – The percentage of time that a device is operational throughout the year. This is determined by

the number of hours that the device was not operational each year (excluding planned maintenance).

The non-operational time should be measured from the time that the contractor is notified of the

failure, to the time that the contractor returns the device to a fully operating state. To calculate uptime,

this time is subtracted from the total hours available for operation, this remainder is then divided by the

total available hours (Uptime (%) =100 x [Available hours-non operational time (hrs)]/Available hours).

Average uptimes should be grouped by device type (CCTV, DMS, etc.).

Uninterrupted power supply (UPS) – A battery backup system designed to instantly provide electrical power for the operation of the controller and traffic signals during a power outage. Work Class Codes – Prequalification codes established by the Department to ensure contractor

competency.

Work Area: In order for a microwave vehicle detector (MVD) to function correctly, it must be mounted such that the detection range is unobstructed and meets the requirements specified in Publication 408 Section 1200. In order to accomplish this, all visual obstructions that prevent this should be reported to the proper department, and the detector should be aligned correctly (per manufacturer’s

instructions). All ITS equipment requires a connection to communications (Cellular, wireless, fiber optics, T1, etc.) and to electrical service (solar, utility pole, etc.). It is important that the methods of communications and electrical service be understood while performing preventative maintenance. For instance, a wireless communications system may require direct line of sight with another antenna. It is essential that the party performing preventative maintenance understand the needs of the work area.

Definition: ITS Structures will be defined as the mounting structure for any ITS devices covered within this maintenance contract. This will include structures that are concurrently utilized for other purposes (static sign, bridges, etc.)

References: PennDOT Publication 647M ITS Site Plans (section 1.3.1)

Scheduling Considerations: Preventative maintenance is to be completed a minimum of twice per year for each device, prior to and after the winter season of each year (unless the manufacturer suggests more); the District ITS Manager may request more as needed. Maintenance activities may require lane closures; this must be considered while scheduling work. ITS structural preventative maintenance checklists are to be completed concurrently with all device specific checklists.

Work Area: The site characteristics and requirements vary for each ITS structure. It is important that the technician performing the preventative maintenance inspection have an understanding of these issues. Coordinate with the District ITS manager and BQAD as needed.


Activity Description: This activity includes the routing inspection of

ITS structures and related hardware. All

preventative maintenance checklists and the

Preventative Maintenance Report Form must

be completed and reported to the District ITS

manager for this work to be considered
