The invention relates to the technical field of intelligent traffic, and discloses a non-signalized intersection fleet cooperative passing method and system, and the method and system comprise the following steps: firstly constructing an intersection scene; information of all motorcades in the intersection area is obtained through the central controller; then establishing a vehicle passing and variable speed limit strategy process; calculating the optimal passing sequence of the motorcade in the control area by using the information according to a rolling time domain algorithm; meanwhile, the motorcade in the variable speed limit area receives a controller instruction to adjust the motorcade and the speed according to the passing time of the front motorcade and the reserved gap, and after entering the control area, the motorcade calculates the passing sequence according to a rolling time domain algorithm to sequentially pass through; compared with the prior art, the method solves the problem of conflict when vehicles at the entrance lanes of the non-signalized intersection enter the intersection at the same time, guarantees the integrity of the vehicle fleet, improves the capacity, passing efficiency and safety of the intersection, reduces the waiting and stagnation of the vehicles, and provides a high-efficiency system architecture for the cooperative passing of the vehicle fleet at the non-signalized intersection.
本发明涉及智能交通技术领域,公开了一种无信号交叉口车队协同通行方法及系统,所述方法及系统包括以下步骤:先构建交叉口场景;通过中央控制器获取交叉口区域内所有车队信息;然后建立车辆通行和可变限速策略流程;利用信息依据滚动时域算法计算出控制区域车队的最佳通行顺序;同时可变限速区的车队根据前方车队通行时间和所留间隙接收控制器指令调整车队和车速,进入控制区后按照滚动时域算法计算通行次序依次通过;与现有技术相比,所述发明解决了无信号交叉口各进口道车辆同时进入交叉口内部冲突的问题,保证车队完整性,提高了交叉口容量、通行效率、安全、减少车辆等待、停滞,为无信号交叉口车队协同通行提供一个高效系统架构。
