津静公路公寓交叉口交通安全渠化设计 Safty Channelization Design of Intersection Near The Apartment in JinJing highway  摘 要 本文综合应用了交通工程、计算机应用等多门学科的知识，通过理论总结和分析、实地交通调查和数据处理计算，用渠化的方法来提高信号交叉口的服务水平。主要包括以下几个方面： （1）依据交叉口渠化国内外研究现状及相关基础知识，从机动车流、非机动车车流和行人流三个方面分析其交通流特点。 （2）探讨了大型平面交叉口渠化措施，结合津静公路公寓交叉口实际交通流特点，对于机动车流，进行了交通渠化，以提高交叉口的通行能力；对于非机动车流，提出了设置自行车专用道，以减少机非冲突；对于行人流，提设置行人过街安全岛，以保证路口行人过街安全。 （3）通过对车辆延误、通行能力、行人过街安全系数等指标的改变，评价交叉口渠化后的服务水平。 本文应用AutoCAD画图软件对交叉口渠化的状况进行了绘制，通过交叉口的定性与定量分析，证明渠化方案在该大型平面交叉口的合理性与可行性。 关键词：交叉口；渠化；安全岛；通行能力； 延误 ABSTRACT The paper apply for multi-discipline konwledge comprehensively,such as traffic engineering、compeer application，through theoretical summary and analysis、field traffic surveys and data-process computing,drainage of the method used to increase the level of service at signalized intersection.including mainly the following aspects: (1) According to the research status and highly channelizing intersection relevant basic knowledge, from motor vehicle traffic flow, the flow lines and three aspects analyzes its characteristics of traffic flow. (2) Explore the intersection of large, highly channelizing measures gongyu road intersection actual traffic flow characteristics, for mobile phase, combined with traffic forward to turn left turn set, in order to improve the capacity of intersection, Non maneuvering for traffic, put forward to reduce the bicycle racks, set the machine; People in line, puts forward the pedestrian street, second set pedestrian street, to ensure the safe pedestrian street intersection. (3) Through the vehicle delay, capacity, safety factor of pedestrian crossing and other indicators of change, evaluation of the intersection level of service after the drainage of the final note. In this paper, AutoCAD drawing software based on the situation of Drainage intersection was drawn through the intersection of the qualitative and quantitative analysis to prove channelizing program in the major intersection of rationality and feasibility.
