Abstract: In this paper, the vehicular driving model at the non-signalized intersection is studied based on a large number of experiments and observations. It is considered that traffic stream possesses platoon character when it passes the non-signalized intersection under the situation of larger traffic volume.The capacity and delay of straight vehicles at six types of non-signalized intersections are analyzed by using identical model according to the platoon theory. Finally,the method to determine the actual capacity and limitation capacity of the non-signalized intersection is presented.

Key words: non-signalized intersection, platoon theory, limitation capacityactual, capacity, delay

摘要： 本文在大量现场观测的基础上,研究了无控制交叉口的车流通行模式,认为在交通量较大的情况下,车流通过无控交叉口具有明显的车队特性,并根据车队理论采用同一通用模型分析了六种类型的无控交叉口直行车流在不同到达率水平下的通行能力及延误的变化规律。最后,本文提出了无控交叉口极限通行能力及实用通行能力的确定方法。
