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.
