基于元胞自动机的直线式公交停靠站与信号交叉口相互影响研究

The Interaction Between Signalized Intersection and Its Nearby Curbside Bus Stop Based on Cellular Model

建立了开口边界条件下信号交叉口上、下游直线式停靠站双车道混行元胞自动机模型,利用交通调查数据对模型进行参数标定。选取公交车通行能力与信号交叉口通行能力作为影响程度的量化指标,研究了停靠站到交叉口的距离对量化指标的影响规律,并将模拟结果与经典公式计算结果进行对比。

The curbside stop locating upstream or downstream the signalized intersection is considered by using a two-lane CA model. The parameters are calibrated based on traffic survey data. The capacity of signalized intersection and buses are chosen as evaluating indicators. The effect of the distance L between the bus stop and the intersection on them is studied. The simulation results are compared with classic formula results.
