【摘要】 基于车联网技术设计了一种交叉口辅助通行算法,当单个车辆靠近交叉口时可以获得交叉口信号灯的相位和配时信息,从而规划车辆的行驶速度曲线,避免车辆的紧急加减速以及停车等待等情况的出现,达到减少燃油消耗的目的。此算法只针对交叉口信号灯为绿灯时,车辆在信号灯由绿灯变为红灯的时刻通过交叉口的场景进行相关研究,寻找最少燃油消耗的速度轨迹。研究结果表明,算法对减少车辆的燃油消耗有非常重要的意义。更多还原

【Abstract】 This paper designs an intersection assistance algorithm based vehicle-to-infrastructure communication. When a single vehicle approaches the intersection, it will get the signal phase and timing information, then plan the its speed profile to avoid urgent change of the speed or stop in front of the intersection, and achieve the purpose of reducing fuel consumption. The algorithm is used in specific scenarios that when the intersection signal is green, and the vehicle will arrive the stop line when the signal become red. It is to find out the optimum speed profile of fuel consumption. The research shows that the algorithm is of great significance for reducing fuel consumption.更多还原
