The invention provides a track optimization method for an intelligent networked vehicle (CAV for short in the following text) running by means of a city bus lane. In order to improve the mixed traffic flow state of the CAV and the manually-driven vehicle and more effectively improve the running efficiency of the CAV, the running speed of the CAV is improved by using the running gap of the bus lane, so that the separation of the CAV and the manually-driven vehicle is realized; in the trajectory planning process, the arrival time of the CAV is firstly obtained, whether the CAV can enter a bus lane to run or not is reasonably arranged based on the traffic state of the time after the unoccupied capacity on the urban bus lane and the influence of signals are considered, and then the trajectory of the CAV running on the bus lane is solved and optimized. The method provided by the invention is a feasible and economical planning mode, not only ensures the independent operation of the CAV to a certain extent, but also utilizes part of idle traffic resources.
本发明提供了一种借用城市公交专用道行驶的智能网联车辆(Connected Automated Vehicle,后文简称为CAV)轨迹优化方法。为了改善CAV与人工驾驶车辆的混行交通流状态,更为了有效提升CAV的运行效率,利用公交专用道运行空隙提升CAV运行速度,以此实现CAV与人工驾驶车辆的分离;在轨迹规划过程中,首先获取CAV到达的时刻,基于这一时刻的交通状态,在考虑城市公交专用道上的空余容量以及信号的影响后,合理安排CAV是否可以进入公交车道运行,再对CAV行驶在公交专用道上的轨迹进行求解和优化。本发明方法是一种可行并且相当经济的规划方式,既保证了CAV在一定程度上的独立运行,也利用了被闲置的部分交通资源。
