Abstract

Drivers can modify both their route and their departure time to optimise their urban trips at peak time. The traffic models generally used for large networks (static models) are unsuitable for accurate analysis of this complex microeconomic behaviour. The purpose of this study was to enrich a "real size" model with the conclusions drawn from departure time selection models developed at a smaller scale.

Starting out with the traditional "bottleneck" model, whose simple version is based on very narrow assumptions (one single value of time, one single desired time of arrival, no choice of itineraries, fixed number of users, linear utility function, etc.), we gradually enriched these basic assumptions in order to align the model with a more realistic micro-economical behaviour. We rested the impact of distributed desired arrival times, distributed values of time non-linear utility function, maximum duration between departure time and desired departure time, and flowkpeed relationship. The choice of the set of assumptions has a major impact on the effectiveness and fairness of toll regulation measures.

A formulation was finally applied to a "real size" network, based on equilibrium principle, distributed values of time, and discrete choice between selected departure times. We tested this quasi-dynamic model on a network in the lle-de-France region, and compared the results with the usual models. This seems to be the first real-size application of such a model in the lle-de-France region.
