ITS Design Manual Overview

Purpose• So designers can create concept to

complete plan set and spec package for MDOT ITS projects or other municipal ITS projects.

• Uniform guidelines and design criteria for ITS elements implemented on MS urban freeways, rural freeways, urban arterials and rural roadways.

• Manual doesn’t address specific details designers encounter, so must confirm assumptions with ITS Program Manager.

Typical ITS design elements• Electrical power location• Fiber optic communications infrastructure• Dynamic Message Signs (DMS) • Closed-Circuit Television (CCTV) system • Radar Detection System (RDS)• Video Detection System (VDS)• Road Weather Information System (RWIS)• Highway Advisory Radio (HAR)• Communications Hut building and equipment • Transportation Management Center (TMC)

Introduction • Project Development Process • Use SEMP for SEA then Design Manual

for plan development• SEMP refers to project development

process: • 1) Develop Concept of Operations• 2) Develop system requirements• 3) Develop Project SEA• 4) Detailed Design – this manual

• Steps in Chapter 14 – key are design concept and SEA

General design guidelines

Provides overall guidance for preliminary placement – Details in Sections 3 – 12

• Concept Development • Meet w/ District & ITS staff for scope and limits.

• Research other planned projects and coordinate with others

• Use aerials or plan sheets showing existing alignment and can obtain field control for scaling

• Concept Review

Deployment guidance

General design guidelines steps

• General Device Placement

• Before Field Visit

• While On Field Visit

• Guardrail Considerations

Power Source Design

• Starts in Concept phase

• Early Coordination Required

• What to show on plans

• What are demarcation locations

• When you may need transformer

• Urban vs. Rural area Considerations

• Verify obstacles for routing

ITS Communications Design• Conduit / Fiber Optic Cable Placement Guidelines

• Freeways• Urban Arterials• Rural• Other Agencies• Wireless and Least Broadband

• Field Location Considerations for Fiber / Conduit• Cable Pull boxes and Electrical Pull Boxes

• Options• Cable Type, Construction, Fiber Mode, Count, Reel to Reel

Splicing, Conduit Types

• Fiber Allocation • Communications Design Examples

Fiber Allocation• Communications Path• Strategies:

• Existing vs. New Device Cases; Daisy Chain• How Many Drops / Pair

• Which Fibers are Used• Switch Selection
