A realistically sound method for giving appropriate estimates of link loads which would result from proposed traffic management scheme alterations is indispensable for designing and assessing traffic management schemes in light of traffic distribution. Considering the fact that little work has been done to understand tripmakers' behaviour and in view of the possibility of rapid progress in driver communication and information systems and the possibility of realizing dynamic rerouting schemes which are dependent on network conditions, it would seem desirable to have a model that could calibrate tripmakers' behaviour and control their adaptability to the management system. This paper describes a simulation model of traffic distribution system in urban street networks, which has been designed with the following purpose in mind : a) to replicate tripmakers' behaviour which includes route choice criteria, their perception and elasticity to the network conditions ; b) to make possible the calibration of model behaviour connected with tripmakers' behaviour ; c) to reflect actual traffic phenomena, which include time-dependent characteristics, capacity restraint, and queue build-up phenomena. To best simulate tripmakers' behaviour, it has been assumed that drivers utilize distance and turning frequency as their primary criteria of route choice ; their decisions based on these criteria are then modified by their approximate perception of traffic congestion. An extension of Dial's probabilistic assignment method has been applied to the model. Findings and a discussion based on the medium term results of evaluation work on the behaviour of the model are also given.
