（交通运输）交通运输物流专业毕业论文毕业论文中文摘要城市道路信号交叉口是城市道路的重要节点，它把城市道路相互连接起来构成道路网，其通行能力直接影响城市道路的通达，交叉口的交通流密度过大，将会造成路口的拥挤与堵塞，影响城市道路的正常运行，而提高信号交叉口通行能力、减少交叉口停车延误是城市道路交通追求的目标，鉴于此，以信号交叉口为研究对象，通过典型交叉口的调查，探究其通行能力，并分析信号交叉口的运行状况。对石家庄市体育南大街与槐安路交叉口的通行能力及延误进行交通调查，计算交叉口的通行能力，分析交叉口的运行状况，分析其存在的问题，在此基础上提出提高了信号交叉口通行能力的建议。关键词城市道路；信号交叉口；通行能力；混合交通流毕业论文外文摘要TitleSportsandHuaianRoadSouthStreetintersectionCapacityAnalysisAbstractSignalizedintersectionistheimportantcomponentoftheurbanroad.Itconnectsurbanroaduparoadnetwork,anditscapacitydirectlyaffecttherunningefficiencyoftheurbanroad.Urbanroadwillnotworknormallyifthetrafficcongestionorjamhappenedthesignalintersectionwhenthetrafficflowdesityoftheintersectionistoolarge.Toimprovethetrafficcapacityandreduceparkinganddelayingintheintersectionarethegoalsofurbanroadtraffic.Forreasonabove,thesignalintersectionisstudiedasaresearchobject,andthetrafficcapacityofintersectionisexplored.Therunningstatusofthesignalintersectionisanalyzedinthispaper.SouthStreet,ShijiazhuangCitySportsHuaiAnRoadintersectionwiththetrafficcapacityanddelaytrafficsurveys,calculatedIntersectionabilitytoanalyzetheoperationoftheintersection,andtoanalyzeitsproblems,onthisbasis,proposedtoincreasethesignalcrossingcapacitymouthrecommendations.KeyWords：Urbanroad；Signalintersection；Capacity；Mixedtrafficflow目录1绪论...........................................................................................................................................11.1选题的背景与意义................................................................................................................11.2国内外城市道路交叉口的研究现状..................................................................................21.2.1国外研究现状.....................................................................................................................21.2.2国内研究概况.....................................................................................................................31.3研究的思路与内容................................................................................................................41.3.1研究思路.............................................................................................................................41.3.2研究内容.............................................................................................................................42信号交叉口交通流特征分析..................................................................................................42.1信号交叉口机动车的组成...................................................................................................42.2信号交叉口处车流运行特征...............................................................................................52.3通行能力及其影响因素.......................................................................................................62.3.1启动损失时间和清尾损失时间........................................................................................72.3.2非机动车对通行能力的影响............................................................................................82.3.3通行能力其他影响因素....................................................................................................93体育南大街—槐安路交叉口的调查与现状......................................................................103.1体育南大街与槐安路交叉口现状.....................................................................................103.2交叉口调查设计..................................................................................................................103.2.1调查的地点和时间..........................................................................................................103.2.2主要调查内容...................................................................................................................103.2.3调查方法...........................................................................................................................113.3交叉口的调查......................................................................................................................114体育南大街与槐安路交叉口的分析与评价.......................................................................134.1体育南大街与槐安路交叉口通行能力的计算................................................................134.2体育南大街与槐安路交叉口延误的计算........................................................................164.3.体育南大街与槐安路交叉口服务水平的评价................................................................215体育南大街与槐安路交叉口拥堵的原因及解决方法......................................................235.1通慧桥拥堵的原因分析.....................................................................................................235.2解决建议..............................................................................................................................24结论..............................................................................................................................................26致谢..............................................................................................................................................27参考文献..................................................................................
