Intersection lane layout and signal timing method in automatic driving process
The invention discloses an intersection lane arrangement and signal timing method in an automatic driving process. Under the condition that the automatic driving vehicle and the manual driving vehicleexist at the same time, intersection lane layout and signal timing are carried out at the same time. The method comprises the steps of: establishing an intersection lane layout criterion for trafficflow of mixed driving of automatic driving vehicles and manual driving vehicles; establishing an expression of green light time of each phase of the intersection; proposing a lane traffic capacity grading determination method according to the proportion of the automatic driving vehicles, and establishing traffic volume constraints; and finally, calculating an intersection lane layout scheme and anintersection signal timing scheme. According to the method, intersection lane layout and signal timing are carried out at the same time under the condition of considering mixed driving of automatic driving vehicles and manual driving vehicles in the future, so that the total traffic volume of the intersection is improved, and traffic congestion is reduced.
本发明公开了一种自动驾驶进程中交叉口车道布设与信号配时方法。在考虑自动驾驶车辆和人工驾驶车辆同时存在的情况下，同时进行交叉口车道布设与信号配时。首先，面向自动驾驶车辆和人工驾驶车辆混行的交通流，建立交叉口车道布设准则；之后建立交叉口各相位的绿灯时间的表达式；然后根据自动驾驶车辆的比例，提出车道通行能力分级确定方法，建立交通量约束；最后计算交叉口车道布设方案和交叉口信号配时方案。本发明旨在考虑未来自动驾驶车辆和人工驾驶车辆混行的情况下，同时进行交叉口车道布设和信号配时，进而提升交叉口总通行交通量，降低交通拥堵。
