PUBLIC TRANSPORT ASSIGNMENT CALCULATIONS WITH THE TRANSCOM SUITE

This consideration of the important features of Transcom describes the techniques for the computerized version of a network as well as the assignment calculations (as an example of the utilisation of the computerized version). The transit network information structure framework is described and the details are discussed of its principal concepts: zone, centroid, link, node, section and lines. The details are given of the assignment method which involves a minimum travel time tree where the travel time between 2 nodes is defined by an impedance function. The methods presented here have been implemented in the Montreal Urban Community Transportation Commission network which consists of 3 metro lines and 115 bus lines with 600 nodes in the network.
