Multi-level differential prevention and control method for operation safety of bridge

Abstract

The invention discloses a multi-level differential prevention and control method for the operation safety of a bridge. The method comprises the following steps that: the operation risk level of a to-be-detected bridge is determined; when the operation risk level is A, the prevention and control facilities are traditional traffic safety facilities; when the operation risk level is B level, the prevention and control facilities are traditional traffic safety facilities, a risk early warning system I and a risk disposal system I; when the operation risk level is C, the prevention and control facilities are traditional traffic safety facilities, risk early warning system II, a dynamic speed limiting system and a risk disposal system II; and when the operation risk level is D, the prevention and control facilities are traditional traffic safety facilities, a risk early warning system III, a dynamic speed limiting system and a risk disposal system III. The system can effectively assist a driver, enables a vehicle to safely and smoothly pass through a bridge, improves the traffic quality, improves the traffic service level, and provides a certain technical guarantee for the operation safety of the bridge.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a multi-level differentiated prevention and control method for bridge operation safety based on different risk levels. Background technique [0002] With the rapid development of my country's economy, the total mileage of highways and the number of cars per capita are increasing day by day. Traffic safety risk prevention and control, as the technical support to ensure the safety and efficient operation of road traffic, is playing an increasingly important role in the field of traffic research. Role. A traffic operation safety risk prevention and control technology with risk identification, risk prevention and control, and effect evaluation as the link has been formed. Among them, the intelligent transportation system with roadside traffic safety facilities and vehicle terminals as the carrier and wireless communication technology as the medium is Travelers have brought a s...

AI Technical Summary

Problems solved by technology

However, this invention is aimed at bridge operation risk management and control measures, which involves less content, and does not propose a multi-level prevention and control technology for bridge operation safety based on different risk levels and a new ITS equipment configuration scheme

[0007] To sum up, the existing traffic risk prevention and control method system has been relatively mature in highways and urban roads. However, with the rapid development of intelligent transportation technology, there is still a lack of integration of traditional traffic engineering facilities and new ITS equipment based on human factors. , multi-level prevention and control method of operation safety with step-by-step transition

Especially for bridges, the existing achievements mostly consider structural risks, and lack of analysis and research on traffic operation safety
