摘要: 以可插车间隙理论和概率论为基础, 建立了固定与可变交织区长度的提前右转组织方式下右转机动车通行能力计算模型与延长交织区所能够增加的通行能力的计算模型, 提出了提前右转组织方式的适用条件。以平均延误为指标, 对比分析了两种组织方式下右转机动车的运行效果, 基于Webster信号配时方法, 对实行提前右转方式的交叉口内直行和左转车流的通行能力进行了分析。分析结果表明: 采用提前右转组织方式后交叉口直行和左转通行能力增加; 在右转机动车提前右转能够满足通行能力时, 提前右转可减小冲突区的面积, 否则, 可以通过延长交织区长度来增加通行能力, 以减少右转车的平均延误。Abstract: Calculating models of passing capacity for fixed and variable weaving area lengths on advance right-turn were given by using gap acceptance theory and probability theory, and calculating models of increasing capacity by prolonging weaving areas were obtained, the application conditions of planning methods on advance right-turn were put forward, the running effects of motor vehicles were compared with the index of vehicle average delay in the weaving areas, and the capacities of left-turn and straight vehicles were analyzed by using Webster signalized timing methods at advance right-turn intersection.Analysis result shows that the capacities of straight and left-turn vehicles at intersection increase when advance right-turn planning method is adopted; when advance right-turn vehicles satisfy passing capacity, traffic conflict area can be decreased by using advance right-turn planning method, otherwise, prolonging weaving areas can be used to add passing capacity and decrease the average delays of right-turn motor vehicles.
