Runaway vehicle guide system and method for long downhill road section of mountain highway

Abstract

The invention relates to the technical field of the traffic safety, and specifically relates to a runaway vehicle guide system and method for a long downhill road section of a mountain highway. The system comprises a runaway vehicle judgment system, a runaway vehicle guide system and a control decision-making system; and the method comprises the following steps: when a vehicle enters a work region, a monitoring facility performs real-time monitoring on a passing vehicle speed and running state; the runaway vehicle judgment system judges whether the vehicle is runaway according to the monitoring data; if the vehicle is runaway, the control decision-making system controls the runaway vehicle guide system to work to guide the runaway vehicle; after sensing that the vehicle has pulled away theguide region, a sensing device automatically lands to accomplish the guide of the runaway vehicle. The system and method are designed by combining the specific escape ramp at the mountain highway with the relatively mature liftable road pile technology, a caution light and a mesh are arranged on the liftable guide pile, the guidance of the guide structure is enhanced, and the guide structure hasthe buffer capacity the liftable guide pile; the structure is simple, the mounting and maintenance are convenient, and the system has strong creativity.

Description

Technical field [0001] The invention relates to the technical field of traffic safety, in particular to an out-of-control vehicle guidance system and method aimed at a long downhill section of a mountain expressway. Background technique [0002] The expressway plays a vital role in the development of the regional economy. However, while facilitating the construction of the regional economy, it is also accompanied by a series of traffic accidents. The traffic accident rate has always been high, often causing extremely serious casualties and economic The loss is especially obvious in the downhill section of the mountain highway. For the long downhill section where the “1103 Lanzhou South Traffic Accident” occurred, it is very easy for large trucks to grow up and downhill on the long downhill section, causing the vehicle to lose control. Even if an emergency escape lane is set on the roadside, most Drivers may also ignore the existence of emergency escape lanes because of panic. In...

[0002] Expressway plays a vital role in the development of regional economy, but it is also accompanied by a series of traffic accidents while facilitating regional economic construction. The traffic accident rate has always been high, often causing extremely serious casualties and economic Loss, especially on long and downhill sections of mountainous expressways

As far as the long downhill section of the "1103 Lanzhou South Special Traffic Accident" occurred, large trucks are prone to brake failure on this long downhill section, causing the vehicle to lose control. Even if an emergency avoidance lane is set up on the side of the road, most The driver may also ignore the existence of the emergency escape lane because of panic. In addition, some drivers are worried about the reliability of the emergency escape lane, fearing that the car will be destroyed and killed, even if they see the emergency escape lane, they dare not use it , leading to serious traffic accidents
