Description
Technical Field
The utility model belongs to the technical field of traffic, and particularly relates to an active early warning device for tunnel entrance.
Background
In recent years, with rapid development of highways, vehicle speed has been significantly related to accident rate and accident severity. The faster the vehicle speed, the shorter the driver's reaction time to the occurrence of an accident. Studies have shown that the severity of accidents increases with increasing speed at speeds exceeding 96km/h, and that the likelihood of fatal casualties increases rapidly after speeds exceeding 112 km/h. In winter, the road surface at the entrance of the tunnel is easy to freeze, and the braking performance of the vehicle is reduced due to the large temperature difference between the inside and the outside of the tunnel, the braking distance of the vehicle is increased, and traffic accidents are easy to occur at the entrance of the tunnel. And because the brightness difference between the inside and the outside of the tunnel is large, and the adaptability of human eyes to sudden changes of the light intensity is limited, when a vehicle enters the tunnel, the vision of a driver is easy to generate a black hole effect, so that the vehicle speed is reduced, the front and rear running speed difference of the vehicle is large, and the rear-end collision accident of the vehicle is easy to occur.
The existing tunnel entrance speed limiting control scheme only completes real-time monitoring of the vehicle speed, judges the matching degree of the current meteorological conditions and the running vehicle speed, and completes early warning information release. In addition, some expressway tunnel entrance speed limit control methods divide vehicle speeds by utilizing content obtained by cloud computing, and do not consider the problem of influence of communication distance and external environment on signal transmission continuity in actual operation of the device, so that operability is low. Therefore, how to overcome the defects of the prior art is a problem to be solved in the current traffic technical field.
