System Integration and Testing & Commissioning Phase


Design Review

• Three stage design review consisting of Preliminary, Pre-Final and Final Design

• Pre-qualification of suppliers of ancillary equipment

• Designs checked against requirements of the Design, Criteria and Performance Specifications, prior experiences and Safety

• Pre-Final and Final design submission include sub-system interface submissions, testing and control acceptance plans

• Each stage of design typically takes 3-9 months


System Safety Validation

• Project Safety Review (PSR) is a formal structured process for assuring the Safety of rail transport systems

Part II

Enhanced Integrated Fare Systems (EIFS)


Introduction to EIFS

• An overall scheme to improve current ticketing system

• Contract for building the system was awarded in April 1999

• Able to support the Public Transport system for 10 years from the completion to the implementation

• Offers convenience and ease of travel to commuters

Contactless Smartcard Environment for Bus


• To carry out rigorous testing to

evaluate the performance and

reliability of the system on MRT and

LRT

• 40,000 regular rail users generated 1.3

million transactions month when test

started in February 2000 and lasted

for a year

Rail Pilot Test


Bus Pilot Test

• To evaluate the concept of

entry/exit processing on buses as

well as the performance of entry

and exit card readers

• 13,000 regular users of the selected

bus services participated in the

four month test. Started in October

2000, the test generated 170,000

transactions each month


• The Contactless Smart Card improves boarding time in buses by as much as 50%

• Card error rate improved significantly

– Magnetic farecard : 1 in 6,000

– Contactless smart card (rail) : 1 in 170,000

– Contactless smart card (bus) : 1 in 370,000

• Survey findings from Trial participants

– 93.9% feel that using CSC is faster.

– 81.5% feel that using CSC for boarding buses is of less hassle.

– 79.0% feel that using CSC is more convenient

Pilot Test Findings


• Held between 5 November to 17 December 2001

• 300 students generated over 1 million transactions to test performance and fare charging.

• 200 students stress tested the largest MRT Station (Raffles Place)

• Major project problems identified and rectified

System Validation Testing


Public Launch

• The ez-link card launched on 13 April 2002

• Use of ez-link card explained to the public

• Public able to approach the passenger service centres and ticket sales offices to refund their magnetic ticket and purchase contactless smart card

• ez-link card can be purchased at ticketing machines from a later date

• Both EIFS and magnetic system ran in parallel for at least 6 months before the cut over on 1 December 2002

Part II

Electronic Road Pricing

(ERP)


Introduction to ERP

• Manual road pricing under the Area Licensing Scheme in 1975

• Most congested part of the city, 720ha termed the Restricted Zone (RZ)

• Mid 90’s same concept introduced to 3 expressways called the Road Pricing Scheme (RPS)

• ALS and RPS both labour intensive

• An active system called Electronic Road Pricing was implemented on 1 September 1998

Tailor Made System

• $1.5 million offered to 5 tenderers to tailor make a mini system of one gantry and simulated system

• 3 tenderers accepted the offer and allotted test site

• Based on proposal and cost/reliability figures successful contractor chosen

• Two years to complete tender award but possible to gauge if system met specifications

• Also gave the contractor a chance to fine tune his system


System Qualification Tests

• To demonstrate the system met reliability standards

• Took place between December 1996 to August 1997

• Conducted on an unopened stretch of expressway with

12 gantries and 250 IUs fitted to hired vehicles

• Test vehicles chalked up 120,000 transactions per day

• Helped in identifying weakness in system and early

resolution


IU Fitting Programme

• 680,0000registered vehicles given a free IU and installation

• IU held in place by a bracket fitted on the windscreen

• Lower right hand corner chosen as best location as motorist could take a quick glance at the IU

• Ten month programme to mass fit IUs to 680,000 vehicles

• 200 workshops commissioned and mechanics underwent two day course on IU installation

• Lower right hand corner chosen as best location

• IU held in place by a bracket fitted to the windscreen


Publicity Support

• Pamphlets sent to all motorist introducing ERP and IUs installation

• Frequent articles in newspapers, television and radio on ERP

• Public forums with grassroots organisations to explain ERP

• 3 months to ERP test drive held, motorists advised to check correct working of IU and cashcard

• IU clinics held the last few Sundays to ERP
