In order to study the actual traffic capacity of different lanes are closed when there is a traffic accident on the city road.The influence factors of different road actual capacity are analyzed when different lanes are occupied.In this paper,the method of artificial searching is used to calculate the number and type of vehicles passing through the fault section in each signal period after the traffic accident,and the specific value of actual traffic capacity is calculated.The paper analyzes the traffic volume,the intersection ratio of the upper and lower reaches,the turning ratio of the downstream intersection.Do these factors have different effects on actual road capacity when different roads are closed? VISSIM simulation is adopted to validate the analysis result.Finally,it is found that the actual capacity of the closed No.1 and No.2 lane road is better than that of the closed No.2 and No.3 lane road because of the role of the branch.Traffic accidents occur at different locations of the road,but there is a difference in the actual capacity of the road.

本文针对高速公路视频监控盲区，利用隐马尔可夫模型，对上下游路段视频数据进行状态转移分析，并利用卷积神经网络训练车辆行驶序列的HMM 模型，对上下游路段视频数据进行关联分析，给出视频盲区段可能发生的交通事件概率结果及可能发生的事件类型，为高速公路管理者提供辅助决策支持。
我国交通网络逐渐贯穿于野生动物保护区及动物分布比较密集的区域，极易造成野生动物数量减少、种群分散、生境破碎化等不良后果，为保证生态系统的稳定，环境友好的"生态交通"已逐渐成为许多国家交通建设的目标。本文结合国内外工程实例，研究分析了公路建设对野生动物带来的不良影响，进而分别阐述了设计、施工、运营各阶段中应采取的预防及补救措施，其中重点强调了野生动物通道的常见类型、影响因素、细部设计等，可为相关工程
应用车载尾气排放测试系统(PEMS)对南京市"国Ⅲ"排放标准的柴油公交车在公交停靠站处的尾气排放特征进行了实测研究。通过实测数据分析了公交停靠站类型对柴油公交车尾气排放量的影响。采用非参数检验分析港湾式及直线式两种停靠站类型对柴油公交车尾气排放是否会产生显著性影响。基于显著性结果，从站点拥挤情况和公交车在不同类型停靠站处的行驶工况两方面对结果分析讨论，剖析公交停靠站对公交车尾气排放影响机理。研究表

本文基于海量OBD 数据，通过对车辆在限行日以及非限行日的车辆出行率变化、车辆的OD 点变化、车辆的出行距离变化以及车辆的出行时段分布这几个方面展开分析，以探索城市限行措施对小汽车出行行为特征的影响。分析结果表明，在限行日样本车辆的出行率不足非限行日50％，其中35％的样本车辆不在限行日出行。出行距离的平均数及中位数对比非限行日减少了40％，通过对一周出行距离的计算，在这一周内限行措施使得北京市五
步行指数(walkability index)是一种量化测度步行性的方法，国内外的诸多研究都表明步行环境对步行出行方式、步行路径选择有显著影响，而既有步行指数模型未能考虑步行者对街道环境的整体感知。本文在既有步行指数模型基础上，进一步考虑步行环境的影响，通过SP 调查确定步行环境表征因素，将步行路权形式及步行道宽度、沿线机动车开口密度、沿街界面积极程度及过街道路红线宽度5 个影响步行环境的关键因素
