COMPUTER USER MANUAL FOR PROGRAM "LATM"--A PROGRAM PACKAGE FOR LOCAL AREA TRAFFIC MODELLING

The package produces short duration traffic assignments for small area networks representing part of an urban area. It can be used for the evaluation of alternative traffic systems management schemes, studies of traffic generators such as shopping centres, or studies of congestion and network performance. The package uses externally supplied, dynamic travel demands over a specified time interval (eg a peak hour) which is itself divided into a number of computation sub-intervals. Demand is assumed to be constant in each sub-interval, but may vary between sub-intervals. Network travel conditions are also varied between sub-intervals. It is possible to distinguish between different turning manoeuvres at intersections, between intersection types, and between road and street types. Queues may exist on all intersection approaches. The model uses a probabilistic path choice procedure based on perceived travel times to account for the possible multiplicity of available network paths of comparable travel time and the assumed imperfect knowledge of the network by travellers.
