| 摘 要： | 微观交通仿真模型在交通系统管理、控制和优化中得到了广泛的应用，大多数仿真模型参数均是针对模型开发国家的交通情况确定的，并不一定适合我国国情。提出了微观仿真模型参数校正流程，然后以合肥市大东门区域VISSIM仿真系统模型为实例，建立了仿真模型参数校正的遗传模拟退火启发式算法，实现了对VISSIM的仿真参数的自动化校正，根据实测结果和仿真实验比较分析，验证了算法的有效性。

| Abstract: | 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 of micro-simulation parameter values was proposed.Finally,field experimental results and simulation analysis were compared,which have proven that the algorithm is proper. |
