Expressway exit ramp multi-stage sight induction system

Abstract

The invention relates to the technical field of road traffic safety, in particular to an expressway exit ramp multi-stage sight induction system. The system involves a plurality of low-frequency single-layer linear induction marks arranged behind a left side guardrail of an exit ramp, a multi-frequency multi-layer linear induction mark arranged behind the left guardrail of the exit ramp, continuous high-frequency protruding road signs arranged on the edge line of an exit ramp deceleration lane starting lane, a plurality of anti-collision buckets arranged at the positions, close to the inner side of the guardrail, of the nose end of the exit ramp, a safety island protection facility arranged at the position, close to the inner side of the guardrail, of the nose end of the exit ramp, and aninformation induction device. According to the system, the above structure is adopted, the single-layer linear induction marks, the multi-layer linear induction mark, protruding road signs, the anti-collision buckets, the safety island protection facility and the information induction device are combined, the visual illusion of a driver is relieved through multi-frequency visual information stimulation, the visual requirement of the driver is met, the speed sense and the direction sense of the driver are improved, and the safety of expressway exit ramp traffic is guaranteed.

Description

technical field [0001] The invention relates to the technical field of road traffic safety, in particular to a multi-level line-of-sight guidance system for expressway exit ramps. Background technique [0002] Expressway is the inevitable product of social and economic development and an important symbol of road traffic modernization, and off-ramp is an important part of expressway. Expressway traffic safety is also a major problem in road traffic safety, among which accidents on the exit ramp of expressways are particularly prominent. [0003] According to domestic and foreign statistical studies on highway traffic safety accidents, it is shown that the number of accidents on off-ramps accounts for about 40% of all traffic safety accidents on expressways. During the process of the vehicle changing from the main lane of the expressway to deceleration diversion and entering the exit ramp, the driver's driving task is complicated, and the vehicle needs to perform complex oper...

Problems solved by technology

However, the location, number and content of the signs are not set reasonably, which leads to the driver's inability to recognize them in time, which is not conducive to the driver's correct judgment and control of the vehicle state.

In addition, the lane edge line in the existing ramp area is a white solid line, and the setting function is single. At night, the driver cannot judge the position and alignment of the exit ramp.
