Rear-end collision warning(RCW)is frequently triggered incorrectly in city condition,while missing alarm is also found in turning around condition.False alarm is caused by unruly driving behavior frequently seen in China according to statistical exper-iments,and alarm performance decays seriously(even missing alarm occurs)within a short period time after turning around is comple-ted.A strategy using host vehicle speed,steering angle and millimeter-wave radar signal of lane change decision system to identify host vehicles real-time running condition is proposed,and then RCW warning region is modified dynamically.False alarm rate is reduced significantly,and alarm performance is improved obviously after the strategy is applied,according to public road test and ground experi-ment results.

步行与自行车出行依然是我国大多数中小城市最普遍的出行方式,但慢行交通却常常面临路权难以保障、规划难以落地、设计难以优先的困境.这与市域慢行OD量化预测缺乏、路网慢行效益量化评价缺位、断面慢行分布规律分析缺失不无关系.以沧州市为实证样本,将中小城市慢行空间划分为市域、网络、断面三类尺度,建立了慢行热力空间、慢行岛核辐、慢行源汇集三类市域分析模型,提出了慢行通勤通学廊道、休闲文化廊道两类网络分析模型,

针对目前北京市居住区停车难、停车乱等突出问题,采用停车资源供需调查、统计分析等方法,分析居住区车辆构成、停放特征及停放规律,提出居住停车区域认证机制,从认证的原则、职责分工、工作流程、监督管理等方面为缓解北京市居住区的停车难问题提供一定的借鉴意义.
伴随着我国基础设施建设的高速发展,城市铁路客运枢纽在国内大量出现.现有铁路客运枢纽建筑结构往往较为复杂,旅客在枢纽内部需要依靠标志寻找正确路径,而标志数量过多、过乱的问题,往往影响旅客在铁路客运枢纽内部的换乘效率.因此,本文从旅客可接受信息量角度,结合我国人体数据及标志设计物理数据确定了旅客在铁路客运枢纽内部标志设置的最大信息量水平.
