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...

Embodiment

[0091] Such as image 3 As shown, the present invention provides a multi-level differentiated prevention and control method for bridge operation safety based on different risk levels, including:

[0092] By analyzing the weather data of the past years, considering the influence of bad weather on a bridge all year round, and then based on the weather level index, the risk level of the bridge operation is determined. According to the monitoring of the weather station or weather sensor, the area where a certain bridge is located is foggy all the year round, and the annual average visibility is ≤200m, so it can be determined that the operation risk level of the bridge is D level under the visibility index level, and flagship prevention and control facilities should be configured , the configuration plan is traditional traffic safety facilities, risk warning system level III, dynamic speed limit system, and fog induction system level III.

[0093] This plan is based on the level o...
