Countermeasures for. traffic accidents due to road conditions in China

It is believed that the construction of roads cannotcatch up with the development of traffic during thecourse of traffic evolution in the world.In this case,itis necessary to take fully the agreement of safety,roadand environment into account.The causes of traffic ac-cidents are divided into two categories,subjective andobjective causes.Subjective causes are mainly personalfactors,while objective causes include vehicles,roads,traffic and climate factors.In China,an accident is al-ways attribu…

高等级公路纵坡的坡度、坡长限制分析

以我国高等级公路上行驶的典型车型(EQ140)为研究对象,分析高等级公路纵坡的坡度、坡长限制问题．利用汽车行驶理论,依据车辆在公路上的理想行车车速、最低容许车速,得出高等级公路理想的纵坡、不限坡长的最大纵坡和车辆在各种坡度坡道上行驶的减速距离．以这些分析结果为基础,与我国现行公路路线设计规范进行对比分析,并参考美国、日本的公路路线设计标准,提出了我国高等级公路的坡长限制值、公路的最大坡度值,同时给出了陡坡上设置爬坡车道的坡度值参考指标,以供设计人员在公路设计时参考．

10kV配电网单相接地故障定位方法的研究

介绍了一种行波定位方法,将行波反射信号进行小波包分解与重构处理,构造特征矩阵,利用大矩阵来确定故障区段。比较故障线路和正常线路波形,使两波形相减,利用波形差第一个畸变点来确定故障距离。     

Inproved grade length limitation of freeways

In China,the designed speed is adopted to projectspeed in design specification for highway routes.De-signed speed is the foundation parameters of road de-sign to regulate the lowest design standards,and otherproject indexes are chosen according to it.Nowadaysmany scholars of China are realizing the importance ofoperating speed in the field of road engineering,trafficengineering and cost-benefic analysis.In2002,ZhangJian-fei put forward the use of operating speed as basicparameters instead of…     

道路服务水平的灰色评价方法

Research on traffic congestion mechanism and countermeasures ased on dynamic traffic assignment

Traffic congestion is widely distributed around a network. Generally, to analyze traffic congestion,static traffic eapacity is adopted. But dynamic eharacteristics must be studied because congestion is a dynamic process. A Dvnamic Traffic Assignment modeling fundamental combined with an urban congestion analysis method is studied in this paper. Three methods are based on congesfion analysis, and the stochastic user optimal DTA models are esperially considered. Correspondingly, a dynamic system optimal model is suggested for responding congestion countermeasures and an ideal user optimal model for predicted congestion countermeasure respectively.
