摘要:

为实现交通多状态演化下的仿真连续性,解决多状态交通只能利用单状态交通进行多次仿真实现的问题,利用VISSIM仿真软件的二次开发接口,构建连续交通事件仿真中间件模型,将原本两个相关联的交通仿真事件进行联合驱动。利用C#与数据库进行VISSIM-COM二次开发,选用重庆市渝中区钢花路与柏华街交叉口的调查数据,对其“平时-拥堵-消散”的交通运行状态进行连续仿真验证。实验结果表明:连续仿真中会分别产生波速为-16.3 km/h和-7.47 km/h的交通波,且连续仿真与实际调查的平均延误、总延误、停车次数和平均速度在数据上更为接近,其差值分别为1.318 s、0.748 h、308次和0.647 km/h,相较于单次仿真,连续仿真与实际调查数据更为接近。

Abstract:

In order to realize the simulation continuity of the multi-state evolution of traffic and to solve the problem that multi-state traffic can only be simulated by single state traffic through multiple times, the middleware model of continuous traffic event simulation is built by the secondary development interface of VISSIM simulation software, and the original two related traffic simulation events are jointly driven. The secondary development of VISSIM-com is carried out by C# and database. The survey data of the intersection of Ganghua Road and Baihua Road in the Yuzhong District of Chongqing is selected as the example, and the continuous simulation verification for the traffic operation state of "Peacetime-Congestion-Dissipation" is carried out. The experimental results show that the traffic waves with speeds of -16.3 km/h and -7.47 km/h will be generated in the continuous simulation, and the average delay, total delay, parking times and average speed of the continuous simulation are more accurate, while the differences are 1.318 s, 0.748 h, 308 times and 0.647 km/h, respectively. Compared with the single simulation, the continuous simulation and the actual survey data are more consistent.
