摘　　要：为了提高BRT(bus rapid transit)专用道的利用率,基于车辆道路信息集成及协作技术,提出BRT专用道路权时分复用的车路协作方法,建立了BRT专用道时分复用的车路协作控制策略模型。研究了分段式BRT行程时间预测算法,结合实时交通流信息,建立车辆借还BRT专用道的换道时间模型,规划了车辆借还协作时序。实验表明,车辆协作控制策略中行程时间预测和借还时间估计接近实际值,并能够有效地实现专用道的时分复用,而不干扰BRT的优先运行。In order to increase the availability of the part-time idle BRT-lane, this paper proposes a method of time division multiplexing （TDM） to share BRT-lane with other kind of vehicles based on vehicle-road collaboration. The TDM control strategy is established based on Vehicle-Infrastructure Integration and vehicles col- laboration. The algorithm is researched to forecast the segmented BRT travel time. According to the real time traffic information, a comprehensive model is given to estimate the vehicles＇ lane-changing time from/to the BRT-lane to/ from its neighbor lane and determine the timing sequence for vehicles collaboration. Finally the experiment demon- strates that the predicted value of the travel time and lane-changing time is closed to the true value. The control strategy of the vehicles collaboration could promise other kind of vehicles to share BRT-lane without disturbing BRT ＇s priority.
