城市道路平面交叉口现状分析和控制方案设计——以昆明市教场中路与教场北路交叉口为例

摘要

道路交叉口的交通信号控制，旨在通过减少平面交叉口内交通流所产生的冲突点和交织点，提高路口的通行能力，使交通流在交叉路口内能够确保安全并快速通过。城市道路交叉口往往交通流情况复杂，人员密集，交通流量大，一旦缺乏有效的交通控制方式，极易造成交通秩序混乱并引发交通拥堵。本文通过对昆明市一个道路交叉口交通现状进行调查与分析研究，设计并提出合理有效的交通控制方案。%Traffic signal control in the intersections is aiming at reducing conflict points and weaving nodes, improving the traffic capacity of crossroads, which enables vehicles can pass through crossroads quickly and safely. Traffic situation is usually complex in intersections, because of crowded population and vehicles. If there is no effective traffic control, then the traffic could be in chaos and further causes traffic congestion. This essay, by making case study of one intersection in Kunming, designs and proposes scientific and effective traffic control scheme.
