Description
Technical Field
The invention belongs to the technical field of intelligent transportation, and particularly relates to a comprehensive solution system for urban viaduct road safety protection.
Background
With the rapid development of cities, urban roads are more and more crowded, and in order to reduce traffic jam, most cities relieve traffic pressure by newly building viaducts. However, for a long time, the road safety of urban viaducts is seriously threatened by the over-limit vehicles on the bridge, and the serious potential safety hazard is also brought to the traffic under the bridge. In recent years, viaduct road collapse events frequently occur due to over-limit vehicle boarding. At present, the problem that no effective means is available for controlling the overrun vehicle to drive into the urban viaduct road exists. The method is characterized by comprising the following steps:
although fixed height limiting frames are arranged at upper bridge openings of some national provinces and urban elevated roads, the limiting means is single, the limiting means can only be used for limiting ultrahigh vehicles, the overweight vehicles cannot be controlled, the height of the fixed height limiting frames cannot be freely adjusted, and emergency situations cannot be met.
At present, the dynamic weighing of vehicles is mainly applied to overload control and over-management of the freight vehicles on the highway, and the dynamic weighing of the vehicles is not applied to weighing of non-freight vehicles at the bridge opening of the urban viaduct or application of the dynamic weighing of the vehicles and an intelligent height limiting control system for linkage so as to prevent the over-limit vehicles from driving into the viaduct.
And thirdly, height limiting and weight limiting marks are also arranged at bridge openings of part of urban viaducts, but real-time overrun event detection and early warning distribution and control are lacked, and evidence obtaining and punishment on overrun behaviors cannot be realized after overrun events occur.
Fourthly, the invention (application patent number: CN 111489559A-system and method for monitoring and early warning of overload of viaduct) obtains vehicle weight data through a dynamic weighing module and then compares the vehicle weight data with the anti-overturning force of the viaduct, and when the vehicle weight is greater than the anti-overturning force of the viaduct, the vehicle is marked as an overload dangerous vehicle and is fed back in time; otherwise, the system is directly released.
The invention has the following disadvantages:
1. the supervision means is single: the invention only controls the overweight vehicles, does not relate to the control of the ultrahigh vehicles, and cannot effectively protect the safety of the viaduct road.
2. The executable degree is not strong: the invention provides that when a traffic police team monitoring center receives an overload dangerous vehicle signal transmitted by a data analysis module and a snapshot image signal of an overload dangerous vehicle transmitted by a monitoring snapshot module, a vehicle driver is immediately contacted to inform a vehicle driver of the danger of an upper bridge and stop the upper bridge, and meanwhile, a nearby team on-duty personnel is informed to rapidly arrive at the site for processing. The urban road is different from a highway, the traffic flow is large, the traffic flow is endless, the spatial position of an upper bridge opening is limited, when an overloaded vehicle is found, law enforcement personnel do not have time and space to guide the overloaded vehicle to drive into a nearby inspection station for fine inspection or go to the site for stopping treatment, otherwise, the urban road is seriously congested, and the urban road is not suitable for the traffic condition of the urban road. In addition, traffic police departments also do not have administrative authority over overloaded vehicles. Therefore, the method for preventing the overrun vehicle from driving into the viaduct is not highly executable.
