The Role of Traffic Simulation in Traffic Signal Control System Development
نویسنده
چکیده
A b s w 6 In USA, trailic simulation was originally developed to evaluate the traffic signal control system in the 1970s by the Federal Highway Administration (FHWA). This paper fin1 introduces the traflic signal control system software development process developed a t Traffic Research Laboratory, in which trailic simulation is integrated to develop, debug, test and evaluate traflic signal control system software. The topics related to traflic simulation software and the interface between traffic simulation and traffic signal control devices are discussed. Next, those key roles are demonstrated in five prototype developments under FHWA's Adaptive Control System programs. Finally, the htum activities in this area, including FHWA's Next Generation of Simulation program, the ACS-Lilt program, the National Transportation Communications for ITS Protocol compliant interface in CORSIXI. and the possibilities of creating a benchmark test nework and CORSIM application server are discussed.

متن کاملThe Development of Maximum Likelihood Estimation Approaches for Adaptive Estimation of Free Speed and Critical Density in Vehicle Freeways
The performance of many traffic control strategies depends on how much the traffic flow models have been accurately calibrated. One of the most applicable traffic flow model in traffic control and management is LWR or METANET model. Practically, key parameters in LWR model, including free flow speed and critical density, are parameterized using flow and speed measurements gathered by inductive ...
