The invention discloses a method and device for improving the traffic efficiency of an intersection under mixed traffic flow based on V2X, and the method comprises the steps: obtaining the first time when a first vehicle passes through the intersection when the traffic phase of a signal lamp in the driving direction of the first vehicle is red; according to the driving state of the second vehicle, whether the second vehicle drives into the intersection within the first time is judged; if not, the roadside intelligent infrastructure changes the passing phase of the signal lamp in the driving direction of the first vehicle into a passable phase, so that the first vehicle passes through the intersection; if yes, the first vehicle stops and waits until the passing phase of the signal lamp in the driving direction of the first vehicle is the passable phase or no second vehicle drives into the intersection within the time when the first vehicle accelerates to pass through the intersection at the comfortable acceleration, and then the first vehicle passes through the intersection. According to the invention, the problem that the intersection traffic efficiency is reduced because the phase state of the intersection traffic signal lamp is fixed within a certain period of time is solved.
本发明公开了一种基于V2X的提高混合交通流下路口通行效率的方法及装置,该方法包括:当第一车辆行驶方向的信号灯的通行相位为红灯时,获取第一车辆通过该交叉路口的第一时间;根据第二车辆的行驶状态,判断第一时间内是否有第二车辆驶入该交叉路口;若否,则路侧智能基础设施将第一车辆行驶方向的信号灯的通行相位更改为可通行相位,使第一车辆通过该交叉路口;若是,则第一车辆停车等待,直至第一车辆行驶方向的信号灯的通行相位为可通行相位或第一车辆以舒适加速度加速通过该交叉路口的时间内无第二车辆驶入该交叉路口后,第一车辆再通过该交叉路口。本发明解决了路口交通信号灯的相位状态在一定的时间内固定不变而造成路口通行效率降低的问题。
