Problems solved by technology

[0003] However, since trams usually share road space with urban road traffic, especially at intersections, their operation is easily disturbed by other factors
At present, most of the domestic trams adopt the signal priority method at intersections, but if there is no previous simulation analysis, it may cause traffic jams

Embodiment

[0113] Combined with the implementation case of Suzhou Tram Line 1, the simulation output is further explained:

[0114] Suzhou Tram Line 1 has a total length of 18.19km and 10 stations. The tram used is the Bombardiar Flexity2 type introduced by Puzhen Vehicle Co., Ltd. The relevant operating parameters are shown in Table 1. In addition, the actual operating speed of the line is 50km / h, and the speed limit for passing through the upstream and downstream of the intersection is 15km / h, and the priority strategy of unconditional active priority is adopted when passing through the signalized intersection.

[0115] Table 1 Tram operating parameters

[0116]

[0117] The running time and stop time of trams in each section in actual operation were collected by means of follow-up survey, and the comparison between the field observation data and the simulation results is shown in Table 2. After comparison, it can be found that the difference between the two is within 4%.

Abstract

The invention discloses a tramcar simulation system based on road traffic interaction. The tramcar simulation system comprises a tramcar passenger module, a tramcar operation module, a tramcar equipment module, a road traffic module and an output module. The real running process of the tramcar is simulated, besides the running process of the tramcar, various traffic participants involved in a tramcar system can be synchronously simulated, real-time interaction with road traffic simulation is completed through a COM interface of the VISSIM, deep integration with road traffic simulation software VISSIM is achieved, the influence of the interaction between the tramcar signal and the road traffic signal on the regional traffic network is reflected, the signal priority strategy of the tramcar at the intersection is realized, and the support is provided for the efficient operation of the tramcar. And the efficiency of the tramcar operation plan is evaluated, and the road traffic signal timing is correspondingly adjusted, so that an efficient driving scheme can be conveniently formulated.

Description

technical field [0001] The invention relates to a tram simulation system based on road traffic interaction, which belongs to the technical field of trams. Background technique [0002] In recent years, as a means of transportation with the advantages of medium capacity, low noise, low pollution and energy saving, trams have developed rapidly in major cities, and have been built and put into operation in many places, such as Dalian, Tianjin, Guangzhou, Suzhou And Nanjing, etc. At the same time, there are still many tram lines under construction. [0003] However, since trams usually share road space with urban road traffic, especially at intersections, their running process is easily disturbed by other factors. At present, most of the domestic trams adopt the signal priority method at intersections, but if there is no previous simulation analysis, it may cause traffic jams. [0004] Therefore, without affecting the normal operation of road traffic, it is a key content to re...
