ROAD CONGESTION ASSESSMENT "FROM THEORY TO PRACTICE": CASE OF THE GREATER MONTREAL ROAD NETWORK

This paper outlines the current congestion-related concepts, the measurements and indicators used elsewhere, and describes the method and indicators developed for Greater Montreal. The paper also explains the computerized methods used to measure queues. The systems were designed in the framework of an MTQ ongoing traffic survey program in the Montreal area, aimed at measuring the evolution of travel times. Two computerized survey methods were designed to measure the position of vehicles. The Odometer technique uses vehicle odometers, while the other method relies on Global Positioning Systems. Either apparatus allows recording, second-by-second, of the exact position of vehicles and computes running speed, travel time and position, length and duration of queues, and delay rates. Computer applications were developed to process collected data and generate synthesis reports that yield a comprehensive rendering of the morphology of congestion on the Greater Montreal road network. Results, depicting queues, travel times, and speeds were mapped and are shown in MapInfo format.
