A cell-based multiple vehicle type dynamic user equilibrium model with physical queues

摘要: This paper proposes a cell-based multiple vehicle type dynamic user equilibrium model with physical queues. A single-type traffic flow is extended to general case types that can be partly solved by the time-space discretization method. Then, network version of cell transmission given. An integrated variational inequality (VI) formulation presented capture complex traveler choice behaviors such as route and departure time choices. Furthermore, genetic algorithm flow-swapping method adopted solve VI problem. Two examples are used evaluate properties this formulation. The results show reflect phenomena, speed consistent under congested conditions, queue formation dissipation so on. Moreover, solutions approximately follow conditions.
