The invention relates to the field of traffic control, in particular to a tunnel early warning and traffic diversion method. The method comprises the following steps: collecting tunnel vehicle passing data; collecting meteorological data of the tunnel; calculating a vehicle passing index X of the tunnel according to the tunnel vehicle passing data; obtaining a severe weather index Y according to the meteorological data of the tunnel; calculating a tunnel early warning index M according to the vehicle passing index X and the severe weather index Y: M = the vehicle passing index X * the severe weather index Y; defining a tunnel risk level according to the tunnel early warning index M; and adjusting the upstream first traffic light in the tunnel advancing direction according to the tunnel risk level, and processing the tunnel risk in cooperation with auxiliary measures. Complex equipment and system support are not needed, the cost is low, and real-time monitoring and early warning are easy to achieve. Compared with the prior art, the problems of limited data sources, low algorithm precision and the like can be solved, and the accuracy and comprehensiveness of early warning indexes are improved.

    本发明涉及交通控制领域,具体涉及一种隧道预警和交通导流方法。该方法包括:收集隧道车辆通行数据;收集隧道的气象数据;根据隧道车辆通行数据计算隧道的车辆通行指数X;根据隧道的气象数据得到恶劣天气指数Y;根据车辆通行指数X和恶劣天气指数Y计算隧道预警指数M:M=车辆通行指数X*恶劣天气指数Y;根据隧道预警指数M定义隧道风险级别;根据隧道风险级别调整按隧道前进方向的上游第一个红绿灯,并配合辅助措施处理隧道风险。本发明不需要复杂的设备和系统支持,成本较低且易于实现实时监测和预警。与现有技术相比,本发明可以解决数据来源有限、算法精度不高等问题,提高了预警指数的准确性和全面性。
