The Study Of Modeling Interchange Transportation System And Its Optimization

With the increasing development of city, urban transportation is becoming morecomplicated. Because of the large scale of urban transportation, the urban transportationsystem in big city is now very vulnerable, a little car accident may lead to the gridlock.The rapid development of cities presents the new requirement of urban transportationinfrastructure construction. Nowadays, in most of developed area, urban transportationinfrastructure construction lags behind the city development, which result in the huge pressureof urban transportation. In this paper, by the modeling methods, first judge whether theinterchange is well use of or not, then modeling the interchange and roads nearbytransportation a PROMODEL model, finally use PROMODEL simulating the cars passing bythe system in reality, and a output report comes out. By analyzing the report, find out therelationship between the elements in the system. Simulate the heavy traffic time by modifyingthe model parameters, by analyzing the output report identify the root cause. Proposing aoptimizing program, verify the correctness of the program by simulating the model. Therefore,the method of modeling the transportation system is feasible and valuable reference.
