Title: Complex network based simulation model for transportation network congestion evaluation
Abstract: In order to get insight into the dynamics of transportation network congestion and develop an effective decision making tool for transportation network congestion government,this paper presented a complex network based simulation model for transportation network congestion evaluation. Through introducing the concept of road impedance in complex network theory,complex network model and traffic simulation model were combined successfully to form a complete transportation network congestion simulation model. In addition,this paper also presented a transportation network capacity assessment method based on virtual test vehicle traversing. This approach could efficiently and comprehensively evaluate the network capacity under different conditions. Finally,it implemented a complete transportation network congestion assessment simulation system on PC system based on the above model and conducted simulation experiments to analyze the influence on the transportation network traffic capacity imposed by the number of congested road sections,traffic flow and road network topology. The results of simulation experiments match the classical transportation theory well and it disclosed more dynamic information of transportation network congestion evolution,which means this model can work well for transportation congestion government decision-making.
