不同行人过街信号灯对行人违章的影响分析

Impact of Different Pedestrian Crossing Lights on Violation of Pedestrian

交叉口行人过街信号灯的设置对行人安全非常重要,不同类型的信号灯对行人违章的影响不同。研究了有无倒计时行人过街信号灯对行人违章的影响,及违章行人比例与红灯期间每车道机动车数量的关系。结果表明有倒计时信号灯条件下违章行人比例较大,且行人违章集中在红灯后期,而无倒计时的信号灯行人违章集中在红灯前期。此外,违章行人比例与红灯期间机动车数量无相关关系。

The setting of pedestrian crossing signal at intersection is important to the security of pedestrian. The impact of various pedestrian crossing lights on violation of pedestrian is different. The paper studies the influence of pedestrian crossing light that with and without countdown display on the rate of pedestrian violation, and the relationship between the rate of pedestrian violation and the volume of vehicle passing through during the period of pedestrian red phase. Results show that the rate of violation is larger if the signal is countdown display, and most pedestrians violate in later stage of red phase in this situation. But most pedestrians violate in earlier stage of red phase when the signal has not countdown display. It is found that the rate of pedestrian violation is not affected by vehicular traffic flow.
