A DEPARTURE TIME CHOICE MODEL FOR DYNAMIC ASSIGNMENT ON INTERURBAN NETWORKS Vincent Aguiléra UPE, LVMT, Ecole des Ponts ParisTech

INTRODUCTION The increasing interest for time-varying tolling policies in transportation networks has highlighted the need for dynamic traffic assignment models in which users are allowed to choose both their route from origin to destination and their departure time. In the case of a single route with a bounded capacity, Vickrey (1969) derived the departure rate as the outcome of individual cost minimization. In Vickrey’s model, for a given departure time, individual costs are modelled as continuous, uniminimal and convex functions of the schedule delay, i.e. as a penalty for early or late arrivals at destination. Since then a number of extensions have been proposed, notably to deal with complex networks, multiple origins and multiple destinations. Most of those extensions (see for instance Heydecker and Addison, 2005 or de Palma and Lindsey, 2006) are tailored for studying equilibrium in metropolitan networks, in which commuting travel patterns are assumed: the preferred arrival time to a destination is often taken from a normal distribution around a peak hour, and individual schedule costs essentially follow Vickrey’s model.
