Sensitivity Analysis of a Dynamic Equilibrium Model for Route and Arrival Time Choice

In order to assess the performances of information systems to road users and of demand management measures, it is necessary to simulate dynamics of traffic flows on the transport network and users’ behaviour. This can be accomplished by taking into account several aspects such as users’ information level, travel demand distribution over time and the expected smoothing effect of adopted measures and information systems. A computational procedure to perform this assessment for various traffic scenarios and hypotheses about users’ behaviour is presented in this paper. Moreover, the indicators needed to quantify information systems and demand management effectiveness are identified together with parameters defining traffic scenarios. The results of an application of the procedure as a deterministic simulation tool are also presented and discussed.
