Expressway danger-avoiding lane guidance system

Abstract

The invention relates to the technical field of traffic safety of expressways and especially relates to an expressway danger-avoiding lane guidance system. The system comprises a four-stage mark guidance system and a four-layer linear guidance system. The four-stage mark guidance system comprises a first danger-avoiding lane forecast sign, a second danger-avoiding lane forecast sign, a curve warning sign, a danger-avoiding lane warning sign, a portal type danger-avoiding lane guide sign and a danger-avoiding lane confirmation sign. The four-layer linear guidance system comprises a warning typelinear guidance mark, a circular base type delineator, a protruding road sign, a rectangular delineator, a flexible warning column and an anti-collision barrel. The four-stage mark guidance system provides perfect way-finding information, a purpose of inducing an out-of-control vehicle to a braking slope bed of a danger-avoiding lane is achieved, and a probability that a truck driver misses the danger-avoiding lane is remarkably reduced. The four-layer linear guidance system realizes contour guidance and horizontal, longitudinal and transverse linear guidance of a danger-avoiding lane sectionand adjacent main line obstacles, and reduces the probability of colliding with a front vehicle and the obstacles.

Description

Technical field [0001] The invention relates to the technical field of expressway traffic safety, in particular to an expressway avoidance lane guidance system. Background technique [0002] At present, on the one hand, the long downhill section of the expressway has always been a concentrated section where large trucks frequently have brake failures and major traffic accidents. The establishment of escape lanes has become an effective and necessary measure to increase the safety of the expressway; on the other hand, The existing traffic signs of the avoidance lane lack a unified and mature setting specification, especially the lack of detailed setting of the avoidance lane signs in the main line area 500m before the avoidance lane, and there are generally low standardization, weak guidance, low warning, etc. problem. In recent years, large trucks that have lost control have missed the escape lane, collided with the vehicle in front or rushed out of the guardrail. At night and ...

AI Technical Summary

Problems solved by technology

At night and in bad weather, the traffic signs of the avoidance lane have insufficient warning and induction effect on the driver. It is difficult for the driver to find the escape lane in time under the weak visual reference system, and it is easy to cause out-of-control vehicles to miss the escape lane. The escape lane is useless, especially It poses a greater safety hazard to the drivers of large trucks
