    摘要:

    为了解决交叉口设置快速公交系统(Bus Rapid Transit,BRT)专用道以及设置BRT固定信号优先导致高峰期道路利用率下降、CO2排放增多、交叉口通行速度减小的问题,该文在将BRT专用道设置为间歇式以及是否启用BRT主动信号优先控制的基础上,提出了4种交叉口BRT控制策略。以设置路中式BRT专用道的十字交叉口为研究对象,基于城市交通模拟(SUMO)软件和其二次开发接口,采用Python语言编程实现了4种控制策略的模拟,通过模拟试验,对比分析了在不同交叉口总交通量Q时各策略的实施效果。结果表明:① 当Q在0~2 400 veh/h的低等交通量区间时,执行不开放专用道且不启用信号优先的策略效果最好;② 当Q在2 400~4 800 veh/h的中等交通量区间时,执行开放专用道但不启用信号优先的策略效果最好;③ 当Q在4 800~7 200 veh/h的高等交通量区间时,执行开放专用道且启用信号优先的策略效果最好。该研究明确了不同BRT控制策略的适用流量范围。

    Abstract:

    The setting of bus rapid transit (BRT) dedicated lanes at intersections and the priority of BRT fixed signals lead to a decrease in road utilization rate, an increase in CO2 emission, and the deceleration of vehicles at intersections during peak hours. To address these issues, four BRT control strategies for intersections were proposed by changing BRT dedicated lanes into intermittent ones and controlling BRT active signal priority. The study focused on intersections implementing median-road BRT dedicated lanes. Based on the simulation of urban mobility (SUMO) software and its secondary development interface, this study succeeded in simulating four control strategies by using Python programming language. Through simulation experiments, the implementation effects of various strategies were compared when the total traffic volume Q at the intersections was in different values. The findings indicate that: ① When Q is in the low traffic volume range of 0?2 400 veh/h, the strategy of not opening the dedicated lane and not enabling signal priority has the best effect. ② When Q is in the medium traffic volume range of 2 400?4 800 veh/h, the strategy of opening the dedicated lane but not enabling signal priority has the best effect. ③ When Q is in the high traffic volume range of 4 800?7 200 veh/h, the strategy of opening the dedicated lane and enabling signal priority has the best effect. The study clearly defines the applicable flow range for different BRT control strategies.
