Freeway network simulation and dynamic traffic assignment with METANET tools Wang, Yibing ; Messmer, Albert ; Papageorgiou, Markos

By: Wang, YibingContributor(s): Messmer, Albert | Papageorgiou, MarkosPublication details: Transportation Research Record, 2001Description: nr 1776, s. 178-88Subject(s): USA | Traffic flow | Motorway | Simulation | Road network | Dynamics | Traffic assignment | | Road user | Macro | | Calculation | 25Bibl.nr: VTI P8167:1776Location: Abstract: Traffic flow simulation and user-optimal dynamic traffic assignment (DTA) in complex freeway networks are considered. For the DTA calculation, feedback laws of the bang-bang, proportional, proportional plus integer (PI) types, and iterative algorithms that use Frank-Wolfe or PI updating formulas are investigated. Recently, METANET, a macroscopic simulation program for freeway networks, was extended to include generic feedback DTA calculation, whereas METANET-DTA, a new METANET derivative, which uses iterative DTA calculation, was developed. Respective program structures and DTA functions are described. Simulation results demonstrate the DTA functions of extended METANET and METANET-DTA.
