摘要
对主路优先控制交叉口的理论通行能力计算方法进行了分析.首先分析了交叉口车流的运行特点;然后基于可插车间隙理论和概率论方法,给出两股车流情况下次路车流通行能力的计算方法,并对主路车流车头时距服从M3分布次路车流的理论模型进行了推导;最后对整个交叉口的“冲突交通流-临界间隙法”进行了分析.
Seeing that the study of intersection capacity is significant to many things, such as intersection planning, designing, reconstruction and management, the capacity calculating method of the main traffic priority control intersection is analyzed in the paper. First of all, the characteristic of vehicle streams at intersection is analyzed. Then, based on the gap acceptance theory and probability method, the capacity calculating method of minor stream is deduced on the condition of two vehicle streams, and theory model is derived when main stream headway fits M3 distribution. Finally, ＂conflict traffic-critical gap＂ method of the whole intersection is introduced.
