Tunnel entrance traffic sign arranging method based on human reliability

Abstract

The invention belongs to the technical field of road traffic safety, and discloses a tunnel entrance traffic sign arranging method based on human reliability. The tunnel entrance traffic sign arranging method comprises the steps that a visual center of a driver is taken as datum, and the visual searching range at a tunnel entrance of the driver is divided into N sub regions; the probability of each sub region scanned by the driver is determined; the effective operation probability of the driver in each sub region is determined; the probability that the driver successfully identifies a target in each sub region is obtained accordingly; the probabilities that the driver successfully identifies the targets in the N sub regions are sorted according to sizes; tunnel entrance traffic signs needing to be arranged are obtained, and the tunnel entrance traffic signs with high importance grades are arranged in the sub regions with high probabilities for successful identification of the targets;and from the driver, taking full account of the actual conditions of the tunnel entrance environment and human reliability, the driver can be guided to orderly pay attention to the traffic signs according to importance of the traffic signs, and meanwhile, accuracy of recognizing the traffic signs of the driver is improved.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety, in particular to a method for setting traffic signs at tunnel entrances based on human factor reliability. Background technique [0002] Since the tunnel is a special structure of the expressway, warning signs, speed limit signs, height limit and width limit signs, etc. are generally set up at the entrance of the tunnel. At the tunnel entrance, signs and signs are densely packed, which can easily lead to excessive transmission of sign information. Drivers have no time to distinguish the importance of information, and it is easy to miss and misread important traffic sign information, which can easily lead to failure of traffic sign information. [0003] However, the location of traffic signs at the entrance of many tunnels is determined according to relevant regulations, which fails to consider the actual situation of road landscape and driver behavior characteristics.

AI Technical Summary

Problems solved by technology

At the entrance of the tunnel, signs and signs are densely packed, which can easily lead to excessive transmission of sign information. Drivers have no time to distinguish the importance of information, and it is easy to miss and misread important traffic sign information, which can easily lead to failure of traffic sign information.

[0003] However, the location of traffic signs at the entrance of many tunnels is determined according to relevant regulations, which fails to consider the actual situation of road landscape and driver behavior characteristics

[0004] Existing research on tunnel traffic signs focuses on the relationship between the design of traffic signs and visibility, ignoring the problem of human failure, and rarely considering the impact of the actual landscape around the tunnel entrance on the driver's subjective cognition
