本发明涉及一种预防隧道出入口附近追尾事故的智能道钉主动控制方法及控制系统,控制中心考虑了拥堵会向上游快速传播的特性计算追尾事故发生条件,考虑驾驶员进出隧道口时由于光线强烈变化而导致的视觉适应时间等综合因素,计算出最优的限速值;随后确定最优限速值与智能道钉颜色的对应关系,并通过上游智能道钉显示当前最优限速值对应的颜色从而实时将限速值传递给进出车辆。本发明采用智能道钉,相比传统的可变信息提示板,具有更低的成本和更广的覆盖区间,同时本发明克服了以往无法主动预防隧道出入口附近追尾事故的缺陷,大幅降低了隧道出入口附近追尾事故风险,具有广泛前景。
The invention relates to an intelligent spike active control method and control system for preventing rear-end collisions near tunnel entrances and exits. A control center calculates rear-end collision occurrence conditions by considering the characteristic that congestion can be rapidly spread to the upstream; the optimal speed limit value is calculated by considering comprehensive factors such as visual adaptation time caused by light intensity change when a driver enters and exits the tunnel portal; and then the corresponding relation between the optimal speed limit value and the color of the intelligent spikes is determined, and the color corresponding to the current optimal speed limit value is displayed through the upstream intelligent spikes, so that the speed limit value is transmitted to the entering and exiting vehicles in real time. Compared with a traditional variable information prompt board, the intelligent spikes are adopted, the cost is lower, the coverage area is wider, meanwhile, the defect that in the prior art, rear-end collision accidents near the tunnel entrance and exit cannot be actively prevented is overcome, the risk of rear-end collision accidents near the tunnel entrance and exit is greatly reduced, and wide prospects are achieved.
