摘　　要：针对目前车辆运行速度值难以获取,特别是新建道路车辆运行速度更难确定的实际状况,采用交通模拟软件V iss im进行获取,不失为一种有效方法。文中探讨了软件中期望车速的设置单元划分原则,根据平曲线行车安全性和车辆动力学性能重点对平面曲线、纵坡和组合线形处期望车速的大小及设定方法进行了研究,并给出了计算方法。It is difficult to get the operation speed, especially in the new building road. The operation speed can be taken by using the Vissim. In this paper, the principle for desired speed＇s setting cells in Vissim was discussed. The value and setting of desired speed of plane curve, vertical slope and combination line type were studied according to the curve travel safety and the vehicle dynamics. Furthermore, the calculation methods were given.
