Microscopic simulation models have been widely used in traffic system management,control and optimization;however,most of the simulation parameters are determined according to the foreign situations and not always suit for our china.Firstly,the procedure for microscopic simulation model calibration was put forward.Then a VISSIM simulation example of Big-East-Door area in Hefei was used.The application of a Genetic Simulated Annealing(GSA)algorithm as an optimization method for finding a suitable combination...
