Development of a Multi-Agent Based Model for Heterogeneous Traffic Flow Analysis

摘要

Vehicular traffic flow management is important to the economic wellbeing of any modern society. This work developed a multiagent based traffic management model to ease traffic flow in a chaotic traffic environment. The developed model employed a multiagent based design principle in which vehicles are treated as interacting intelligent system in a typical road section. Aimsun? 6.1 software was used to obtain information about the traffic flow while the developed model was simulated using MATLAB? software. The results showed that the vehicle speed is a major determinant of heterogeneous traffic flow. As the vehicular speed is increased, the region of transitions which occurred at the critical densities continued to shift leftward on the flowdensity plot. This consequently resulted in predominantly more congested area than the freeflow region, implying that the traffic is becoming more congested. In conclusion, the inclusion of incomplete sets of topology had expanded the solution space that could be investigated which would give better information for traffic management.
