Abstract

Network assignment distributes Origin-Destination (OD) trips in a network, and determines the flow patterns in a traffic network. This research aims at developing simulation-based algorithm for dynamic traffic assignment problems under mixed traffic flow considerations. The algorithm consists of an inner loop that incorporates a direction finding mechanism for the search process for System Optimization (SO) and User Equilibrium (UE) classes based on the simulation results of the current iteration, including experienced vehicular trip times and marginal trip times. Convergence is sought by obtaining search directions for the SO and UE classes. The core is a simulation-assignment model, DynaTAIWAN (Dynamic Traffic Assignment and Information for Wide Area Networks), that allows consideration of individual tripmaker decisions at the origin as well as at each node along the way to the destination, in addition to describing the dynamics of vehicular traffic flow. For the covering abstract see ITRD E134653.
