摘　　要：公交优先是我国各大中城市解决日益严重交通拥堵问题的必然选择,实现交叉口范围内公交快速通行是体现公交优先的关键。饱和路口占用平面交叉口进口道实现公交优先将使道路通行能力受到很大影响。基于预信号控制提出一种新型的交通组织方式,深挖路口空间潜力,实现公交车优先通过路口,同时不减少交叉口通行能力,从而显著地减少公交出行的延误。对实际工程案例进行Vissim仿真评估,工程效果显著。Bus priority is the first choice to solve the increasingly serious traffic congestion in major cities of China. It is key to reflect the bus priority for the realization of fast bus traffic within the intersection range.The road traffic capacity will be greatly influenced by the realization of bus priority at the saturated intersection. Based on the pre-signal control, the article proposes a new traffic organization mode to tap into the potential of intersection space and to realize the bus priority and also not to decrease the traffic capacity of intersection so as to obviously decrease the delay of bus travel. The practical engineering cases are evaluated by VISSIM. The engineering effect is marked.
