基于Flexsim的城市交通路口车辆排队系统仿真模拟——以中山市城桂公路长命水路口为例

A research on urban traffic queueing systems of intersectionsbased on Flexsim-a case study of the intersection of Chenggui Road andChangmingshui Road in Zhongshan City[Abstract]With the development and increase of our economy,the automobilepopularity is growing in China.Meanwhile traffic jams are becoming more often dueto all sorts of factors such as the lack of long-term consideration in the design stage ofcity transportation systems,accidents or new infrastructure constructions whichoccupies the already limited space in city roads.In recent year,due to the constructingof ZhongshanTanzhou Express,two of the four lanes on Chenggui Road is beingoccupied remaining two lanes in use.Infrastructure constructions like this one whichis occupying two of the four lanes in this case will reduce the efficiency of the roadsystem and cause traffic jams.Therefore,taking the intersection of Chenggui Roadand Changmingshui Road in Zhongshan City as an example,this paper collects datathrough field investigation,establishes a simulation model using Flexsim software,and observes outputs of the model,discovers the bottleneck of the system,and putsforward optimization suggestions focusing on traffic lights period.[Key words]queueing system;simulation;Flexsim simulation optimization
