基于驾驶人心理认知行为模型的道路警告标志设置优化

Optimization of Road Warning Signs' Setting Based on Driver's Psychological Cognitive Behavior Model

针对我国道路标志警告功效欠佳、位置不合理等而导致警告标志的功能无法正常发挥的问题,本文运用驾驶人心理认知行为模型并结合行车中停车视距的计算方法,对警告标志的设置位置进行了分析。该方法进一步完善了警告标志位置设置的合理性因素,即引入驾驶人认知心理所产生的心理效应的视认性,使得道路警示标志的布置在充分考虑驾驶人的视认性和车辆减速影响因素的情况下,达到道路警告标志设置的最合理化,进而为道路警示标志的位置设置提供一种更为完善的思路。

This article is aimed at the problem that unperfected effect of the credibility of the warning signs and normal control function such as poor warning effect of road warning signs, drivers' identification difficulties and unreasonable position. The driver behavior model and the calculation method of parking stadia in the road are used in this paper to make effect analysis on the rationality of warning sign setting. The method fully considers the influence factors such as the rationality of the setting of warning sign position, which adds the driver's cognitive psychological visibility of psychological effect to make roads warning sign in full consideration to the layout of the visibility of the driver and vehicle deceleration influence factors, in order to achieve road warning sign to set the rationalization, and provide a better way for road warning sign position setting.
