The Interaction Between Route Guidance and Signal Control: Development of a Multiple User Class Model.

This Working Paper describes the development of a simulation model for route guidance, based on the principle of multiple user class assignment. The model calculates separate routes for guided and unguided drivers in full interaction with each other, assuming user equilibrium, system optimum and stochastic user equilibrium routing for each of the classes. As the model is equilibrium-based, it is most appropriate for the assessment of the long-term behaviour of route guidance systems. Conditions are derived under which the solution to the multiple user class assignment problem in a route guidance context is unique. The paper is finished with a literature overview of previous route guidance model work.
