    摘要:

    准确评价公交停靠站设置在出口附近对出口通行能力的影响,为采取有效的交通设计与管理措施提供依据。根据公交停靠站设置在出口上游和下游两种情况,考虑公交停靠站有无公交车排队溢出,运用间隙接受理论和排队论,建立两种情况下的快速路出口通行能力模型,通过仿真对模型进行验证。结果表明:模型具有较高的精度和可靠型;随着公交车到达率的增大,公交停靠站设置在出口上游时出口通行能力下降更显著;当公交车到达率低于240辆/h时,泊位数的增加对两种情况下的出口通行能力基本没有影响;出口流量的变化对两种情况的出口通行能力影响不大。

    Abstract:

    An accurate evaluation of the effect of bus stops designed in bay style on the expressway near exit points on the main road capacity is the basis for taking effective traffic design and management measures. Depending on a bus stop position to an exit ramp (upstream or downstream) and considering bus stops with overflow and without overflow, the capacity models on the exit for two cases were developed on the basis of gap acceptance theory and queuing theory. A comparison of simulation experiment and model calculation was carried out. Findings show that the suggested models have high accuracy and reliability. As bus arrival rate increases, bus stops located upstream of an exit have a profoundly effect on the capacities. With berth number increasing, there are no significant difference in the capacities for two cases when bus arrival rate is below 240vehicles per hour.With exit volume increasing, the capacities is no obvious for two cases.
