Abstract

A model for the representation of passenger flow using Coloured Petri Nets is proposed. In this model, the locations and the walking routes are modelled as a network of places and transitions, and passengers as tokens moving around in this network. A token is assigned a "colour", which can be used to show information that is carried around by the token, such as destination, the number of passengers that the token represents, and any other data that may be required for evaluating the passenger flows. Passenger flow rate fluctuation and capacity limitation can be included in the model. The model can easily be integrated with train movement models, which can also be expressed using Petri nets. This model yields a simpler representation of passenger flow than those based on fluid-flow modelling, while still being able to handle the reality of the terminal adequately, and is potentially suitable for applications that require accelerated time simulations.
