The invention provides a dynamic emergency lane emptying method based on the Internet of Vehicles. For an upstream road section of an urban road intersection, when an emergency vehicle is detected on a road, firstly, relevant data of the emergency vehicle and the road section are collected; secondly, discretizing the road section into a plurality of grids and calculating the length of the dynamically emptied road section; then, under the principle of a heuristic algorithm and the minimum total emptying cost, the optimal emptying position of the vehicle in the road section and the optimal emptying scheme of the vehicle driving away from the lane are calculated; and finally, according to the optimal clearing scheme of the vehicle, the optimal clearing starting time of the dynamic clearing road section is calculated based on the principle that the emergency lane opening clearing cost is minimum. And the networked vehicle can move according to the emptying scheme so as to complete emergency lane emptying. According to the method, the upstream road section of the intersection is taken as an emptying target, the influence of the queuing length is considered, the emergency vehicle is ensured to safely and efficiently run on the road by dynamically emptying the road space in front of the emergency lane, and meanwhile, the interference to the network-connected vehicle is reduced as much as possible.
本发明提出了一种基于车联网的动态应急车道清空方法。针对城市道路交叉口上游路段,当道路检测到应急车辆时,首先采集应急车辆和路段的相关数据;然后首先将路段离散化为若干网格并计算动态清空路段的长度;接着在启发式算法和清空总成本最小的原则下,计算路段中车辆的最佳清空位置及驶离车道的最佳清空方案;最后根据车辆的最佳清空方案,基于应急车道开启清空成本最小的原则,计算动态清空路段的最佳开始清空时间。网联车便可根据清空方案进行移动以完成应急车道清空。本发明以交叉口上游路段为清空目标,考虑排队长度的影响,通过动态清空应急车道前方道路空间,保障应急车辆在道路上安全高效的行驶,同时尽可能减小对网联车的干扰。
