公交车专用道是一种专用公交车设施，通常位于繁忙的主干道上。使用公交车道是合理的，因为公交车比汽车可以承载更多的乘客。然而，脱离通用交通并指定为公交车专用车道的车道可能会造成其他车道的拥堵，从而引起驾车者的抗议。我们努力开发运营绩效和决策模型，以用于证明和设计主干道上的公交专用道。该模型考虑了两种处理方式下的总体平均人行时间：有和没有公交车专用道。 CORSIM仿真模型用于估计各种主要条件下的公交车和非公交车行驶速度，包括公交车运量、非公交车运量、右转运量、公交车站位置、公交车站密度、公交车停泊点的存在、公交车泊位数量、平均停留时间、绿地率、周期长度、信号偏移和车道数量。在行驶速度与主要条件之间关系的经验建模中，模拟数据被用作现场数据的替代品。速度模型允许在不同的公交车道设计和主要条件下估计人员出行时间。我们发现这些模型在给定输入条件下产生的速度非常接近文献中报道的速度。
Bus lanes are a form of exclusive bus facility typically found along busy arterial streets. The use of bus lanes is justified because buses can carry more passengers than automobiles. However, a lane taken away from general-purpose traffic and designated as a bus-only lane can create congestion in other lanes, causing protests by motorists. An effort was undertaken to develop operational performance and decision models that can be used to justify and design bus lanes on arterial streets. The model considers the overall average person travel time under two treatments: with and without a bus-only lane. The CORSIM simulation model was used to estimate the bus and nonbus travel speeds under various scenarios of prevailing conditions, including bus volume, nonbus volume, right-turn volume, bus stop location, bus stop density, presence of bus bay, number of bus berths, mean dwell time, green ratio, cycle length, signal offset, and number of lanes. The simulated data were used as a substitute for field data in an empirical modeling of relationships between travel speeds and the prevailing conditions. The speed models allow person travel times to be estimated under different bus-lane designs and prevailing conditions. The models were found to produce speeds that closely approximate those reported in the literature for the given input conditions.
