Method and apparatus for acquiring information threshold of traffic sign

Abstract

The embodiments of the invention provide a method and apparatus for acquiring the information threshold of a traffic sign. The method herein includes the following steps: acquiring the threshold valueof vision recognition time when a test driver drives, and the vision recognition time of each traffic sign from various combinations of traffic sign by the test driver; based on the vision recognition time and the threshold value of vision recognition time, acquiring a target traffic sign combination which meet maximum vision recognition condition; and based on the vision recognition time corresponding to each traffic sign of the target traffic sign combination, constructing an information threshold value model, based on the information threshold value model, acquiring the traffic sign information threshold value. A system is intended for executing the aforementioned method. According to the embodiments of the invention, the method herein fully considers the driver's capability of visionrecognition of traffic signs in the driving process, and considers the influence of different traffic sign combinations on driver's vision recognition of traffic signs, increases the accuracy in acquiring traffic information threshold values, and further provides accurate theory basis for configuring traffic signs along the road.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of transportation, and in particular to a method and device for obtaining a traffic sign information threshold. Background technique [0002] With the development of science and technology, cars have increasingly become a necessity in people's lives, and more and more people use cars as a means of transportation. Correspondingly, more reasonable traffic rules and traffic signs are needed to guide people to drive correctly. [0003] The reasonable setting of traffic signs on the road can accurately guide the driver to exercise on the road and reduce the error rate of the driver's operation. In the setting of road traffic signs and the graphic design of traffic signs, it is necessary to study the threshold value of traffic sign information. Information traffic sign information threshold, also known as traffic sign information overload threshold, refers to the value of the largest amount ...

AI Technical Summary

Problems solved by technology

The realization of this method is only suitable for the experiment of static visual recognition of traffic signs, and the data requirements are relatively accurate, otherwise, a linear relationship cannot be formed

This method is too simple, only relying on the linear relationship between the number of information and visual recognition time to deduce the information threshold, and this method is only suitable for the research of static traffic sign information threshold

In real life, the determination of information threshold is based on dynamic driving, and the accuracy of traffic sign information threshold acquisition will affect the setting of traffic signs on the road.
