Detectorization

Strategy

• 2009 study lead by TransLink, Province TransLink, Province of BC, and Transport Canada

• Focus on technologies for region-wide traffic flow monitoring in Metro Vancouver

Probe

Data

1. Collect, disseminate and archive real time traffic flow information for the road network in Metro Vancouver

2. Display real time traffic flow and

Public

ATIS

2. Display real time traffic flow and travel time information on regional ATIS

3. Develop web based application for data analysis, reporting, & sharing

• Probe based traffic flow monitoring system

• Probes based on anonymous tracking of cellular telephone signals

What is RTDS ?

• Unique “signature” data is generated by driving each road

• Traffic flow measurements can be generated by matching real-time cellular message data to the pre-recorded signatures

RTDS Data Coverage

Provincial Highways & MRN

Select Arterials

• Traffic speed & travel time measurements for any route / time period

� Bottleneck identification� Safety studies� Air Quality analyses

Applications & Beneficiaries

• Traffic Engineers

• Transportation Planners

• Transit Planners

• Economists� Air Quality analyses

• Real time Data Sharing

� TMC Video Display� Incident Detection� Fleet Management� ATIS

• Travelling Public

• Road Authorities

• Emergency Services

• Commercial Vehicles

• Economists

• Environmental Engineers

Business Case

On a per-KM basis:

• Sensor –based detection:• $30,000 (capital)• $1,500 (annual O&M)• $1,500 (annual O&M)

• Travel time / speed surveys• $250 (provides snap-shot of 10 runs/period/direction)

• Probe Based• $150 / km / year
