A Traffic Sign Setting Method at Tunnel Entrance Based on Human Reliability

Abstract

The invention belongs to the technical field of road traffic safety, and discloses a traffic sign setting method at a tunnel entrance based on human factor reliability, which includes: taking the driver's visual center as a reference, dividing the driver's visual search range at the tunnel entrance into N subsections area; determine the driver's probability of scanning each sub-area; determine the driver's effective operation probability in each sub-area; thus obtain the probability of the driver's successful identification of the target in each sub-area; the driver's successful identification of the target in the N sub-areas The probability is sorted according to the size; obtain the traffic signs at the tunnel entrance that need to be set, and set the traffic signs at the tunnel entrance with higher importance in the sub-area with a higher probability of successfully identifying the target; starting from the driver, fully consider the actual situation of the tunnel entrance environment The reliability of the situation and people can guide drivers to pay attention to traffic signs in an orderly manner according to the importance of information, and at the same time improve the accuracy of drivers' understanding of traffic signs.

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
