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,车流通过无控制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6种类型的无控制交叉口直行车流在不同交通量水平下的通行能力及延误的变化规律。最后,本文提出了无控制交叉口极限通行能力及实用通行能力的确定方法。
In this paper, the vehicular driving model at a non-signalized intersection is studied, based on large number of observations. The traffic stream passing a non-signalized intersection under the situation of large traffie volume is considered to have a character of platoon. The capacity and delay of straight vehicles for six types of non-signalized intersections are analyzed by using the same model according to the platoon theory. Finally, the method to determine actual capacity and limited capacity of a non-signalized intersection is presented.
