The person capacity of a transit route: a review, assessment and benchmark of static models for network traffic assignment

Thème : transit person capacity
Our objective is to describe and compare five proposal to model the person capacity of a transit route.

The planning of urban public passenger transport often requires considering the capacity constraints and congestion effects. Modelling the person capacity of a transit route has been the purpose of several recent research works to develop network traffic assignment models along the following tracks:

  • effective frequencies, by De Cea and Fernandez, and Cepeda et al;
  • the capacity by route segment, by Lam et al;
  • failure-to-board probability, by Kurauchi et al;
  • strategy based on a user preference set, by Hamdouch et al;
  • availability frequency, by Leurent and Askoura.

Our objective is to describe and compare the models. We characterise and discuss their assumptions and also apply them to a test case which is treated parametrically. We consider specifically:

  • making explicit a capacity constraint;
  • priority for passengers already on board over those boarding;
  • the route’s waiting time for a boarding passenger;
  • the distribution of boarding volumes between the attractive routes from a station to a given destination.
