五邑大学本科毕业设计I摘要交通拥堵已成为困扰当前城市发展的难题，目前国内外很多城市交通拥堵状况仍旧比较严重，我国的机动车拥有量及道路交通流量急剧增加，日益增长的交通需求与城市道路基础设施建设之间的矛盾已成为目前城市交通的主要矛盾，由此导致交通拥挤和堵塞现象频频发生。交通拥堵严重地影响了人们的日常出行活动，制约着城市经济的发展。本文通过调查和分析，建立了交通拥堵模糊评价模型。综合行程速度、行程延误、停车次数、停车时间以及负荷度五种评价指标，对江门市区路网实际调研的数据进行回归拟合分析，确定每种指标的评价参考标准，最终形成科学的交通拥堵模糊评价模型，根据交通拥堵指数的概念评价城市路网的拥堵严重程度。利用本文的模型，可以通过采集到的交通数据，实现对城市路网的定性和定量分析，得出相应路网的交通拥堵系数的大小，确定每个路网的拥堵严重程度，为交通管理部门提供科学合理的依据。关键词交通拥堵；状态评价；模糊；评价指标；交通拥堵指数五邑大学本科毕业设计IIAbstractTrafficcongestionhasbecomeaproblemofthecurrentsituationofcitydevelopment,trafficcongestioninmanycityathomeandabroadisstillrelativelyserious,vehicleourcapacityandtrafficflowincreasesrapidly,thecontradictionbetweentheincreasingtrafficdemandandcityroadinfrastructureconstructionhasbecomethemaincontradictionofthecitytraffic,causingtrafficcongestionandblockingphenomenonoccurredfrequently.Trafficcongestionhasseriouslyaffectedpeople'sdailytrips,restrictsthedevelopmentofcityeconomy.Throughtheinvestigationandanalysis,establishedthefuzzyevaluationmodeloftrafficcongestion.ThensettheevaluationindexsuchasTravelspeed,Traveldelay,thefrequencyofparking,parkingtimeandthedegreesofthesections.RegressionanalysisonthedataofpracticalresearchofJiangmen’surbanarea,determinetheevaluationofeachindexreferencestandard,eventuallyformingthefuzzyevaluationmodeloftrafficcongestion,andputsforwardtheconceptoftrafficcongestionindex,toevaluatetheevaluationoftrafficcongestionstatemodel.Usingthismodel,thetrafficdatacanbecollected,realizethequalitativeandquantitativeanalysisofcityroadnetwork,drawthecorrespondingroadnetworktrafficcongestionindexsize,determineseachnetworkcongestionseverity,providescientificandrationalbasisforthetrafficmanagementdepartment.Keywordstrafficcongestion;evaluation;fuzzy;evaluationindex;trafficcongestionindex五邑大学本科毕业设计III目录摘要..............................................................................................................................................IAbstract........................................................................................................................................II第1章绪论...................................................................................................................................11.1课题背景..........................................................................................................................11.2研究的目的和意义..........................................................................................................11.3交通拥堵评价研究现状..................................................................................................21.4本文研究的主要内容......................................................................................................21.5本文章节安排..................................................................................................................3第2章交通拥堵...........................................................................................................................42.1交通拥堵定义及分类......................................................................................................42.1.1交通拥堵定义.......................................................................................................42.1.2交通拥堵分类.......................................................................................................42.2交通拥堵评价方法..........................................................................................................52.3交通拥堵原因..................................................................................................................62.4本章小结..........................................................................................................................6第3章模糊数学理论...................................................................................................................73.1模糊数学理论概述..........................................................................................................73.2模糊关系..........................................................................................................................73.3模糊集合..........................................................................................................................73.4隶属度及隶属度函数......................................................................................................83.5模糊判别矩阵..................................................................................................................93.6模糊关系合成运算..........................................................................................................93.7模糊数学评价体系..........................................................................................................93.8本章小结........................................................................................................................10第4章交通拥堵状态评价指标的选取.....................................................................................114.1交通拥堵状态评价指标的选取依据............................................................................114.2交通拥堵状态评价指标...........................................
