摘要
从驾驶员心理角度出发,分析驾驶员在交叉口处的决策过程。综合驾驶员行为的影响因素,在对交叉口数据采集和分析的基础上,运用Logistic模型建立了倒计时信号交叉口行为决策模型,并与无倒计时信号交叉口处驾驶员的行为决策进行了比较,最后对影响决策的因素进行了敏感性分析。分析结果表明:倒计时信号显示时间对驾驶员的行为决策存在着显著影响。为城市交通管理者改进倒计时显示屏的设计设置以及在交叉口处采取相应的措施,改善交叉口安全性提供了参考。
Countdown display unit at signalized intersection is one of the most common used but also controversial traffic control equipments. From the perspective of drivers＇ psychology, the drivers＇ behavioral decision-making process and its influence factors were analyzed. Based on the dates surveyed, the Logistic model of drivers＇ behavioral decision-making at signalized intersection with countdown display unit was established which also compared with model without countdown display unit. The sensitivity analysis results of these two models were given at last. The results indicated the countdown display influenced the drivers＇ behavioral decision-making significantly. These fundamental works provided some knowledge to traffic management to further process in the improvement of countdown display setting and gave some advices to promote the safety of intersection.
