PAGE\*MERGEFORMAT19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【摘要】随着我国经济的发展，汽车的普及程度越来越高。而由于各种各样的缘故，堵车现象也随着汽车的普及频繁出现，例如由于道路设计考虑不够长远、交通事故、市政工程建设占用道路资源等原因导致的堵车。最近一年，由于中山坦洲快线的修建，城桂公路位于广东药科大学中山校区北门前的路段位于中央两条车道需要进行围蔽施工，仅余两侧两条车道运行。在市政工程建设占用道路资源的情况下，道路的运行效率便会下降，造成拥堵。基于此，本文以中山市城桂公路长命水路口为例，通过实地调查的方式采集数据，利用Flexsim仿真软件建立仿真模型，观察模型运行之后输出的结果，找出了瓶颈，并针对红绿灯周期提出了优化建议。【关键词】排队系统；仿真模拟；Flexsim仿真优化AresearchonurbantrafficqueueingsystemsofintersectionsbasedonFlexsim——acasestudyoftheintersectionofChengguiRoadandChangmingshuiRoadinZhongshanCity[Abstract]Withthedevelopmentandincreaseofoureconomy,theautomobilepopularityisgrowinginChina.Meanwhiletrafficjamsarebecomingmoreoftenduetoallsortsoffactorssuchasthelackoflong-termconsiderationinthedesignstageofcitytransportationsystems,accidentsornewinfrastructureconstructionswhichoccupiesthealreadylimitedspaceincityroads.Inrecentyear,duetotheconstructingofZhongshanTanzhouExpress,twoofthefourlanesonChengguiRoadisbeingoccupiedremainingtwolanesinuse.Infrastructureconstructionslikethisonewhichisoccupyingtwoofthefourlanesinthiscasewillreducetheefficiencyoftheroadsystemandcausetrafficjams.Therefore,takingtheintersectionofChengguiRoadandChangmingshuiRoadinZhongshanCityasanexample,thispapercollectsdatathroughfieldinvestigation,establishesasimulationmodelusingFlexsimsoftware,andobservesoutputsofthemodel,discoversthebottleneckofthesystem,andputsforwardoptimizationsuggestionsfocusingontrafficlightsperiod.[Keywords]queueingsystem;simulation;Flexsimsimulationoptimization目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc39768523"1前言PAGEREF_Toc39768523\h1HYPERLINK\l"_Toc39768524"1.1选题的目的及意义PAGEREF_Toc39768524\h1HYPERLINK\l"_Toc39768525"1.1.1选题目的PAGEREF_Toc39768525\h1HYPERLINK\l"_Toc39768526"1.1.2选题意义PAGEREF_Toc39768526\h1HYPERLINK\l"_Toc39768527"1.2研究现状PAGEREF_Toc39768527\h1HYPERLINK\l"_Toc39768528"1.2.1国外研究状况PAGEREF_Toc39768528\h1HYPERLINK\l"_Toc39768529"1.2.2国内研究状况PAGEREF_Toc39768529\h2HYPERLINK\l"_Toc397
