A Frequency Based Transit Model for Dynamic Traffic Assignment to Multimodal Networks

The pricing and rationing measures applied to discourage the use of private cars, in order to alleviate the increasing road congestion and the consequent worsening pollution, are not always coupled with a consistent policy aimed at improving the performance, or at least the capacity, of the transit system. As a result, in many modern cities the problem of full transit carriers is becoming increasingly prevalent. Although this situation should be avoided through a correct design of the transit network by suitably increasing the line capacities, it is still important to properly simulate the current scenario in order to justify the resources needed to carry out appropriate interventions. Thus, this paper is interested in modeling dynamic behaviors of heavy congested, urban multimodal (transit and road) networks, where the service is so irregular or so frequent that there is no point for passengers to synchronize their arrival at the stop with the scheduled time of carriers, if any is published. Within this context, the paper aims at properly reproducing the important dynamic congestion phenomenon of the temporary over saturation of roads and transit lines; that is, both the formation and dispersion of passenger queues at transit stops, where passengers wait for the first run of the chosen line actually available to them.
