Although in recent years road victims have been reported to decrease, the growing number of pedestrians involved in road accidents still remains a social concern. This work analyzes the drivers’ behavior in approach to two different configurations of pedestrian zebra crossing: marked by (1) white stripes over the pavement (named “white zebra crossing”) and (2) white stripes on a red-colored pavement (named “red and white zebra crossing”). Even though the latter configuration is nowadays quite widespread on urban environment, there is no scientific evidence of its actual effectiveness in conditioning drivers’ yielding behavior. This study was aimed at verifying the effectiveness of the red and white zebra crossing on improving road safety at pedestrian crossings. A set of synchronized cameras were used to record drivers’ behavior while approaching the pedestrian crossings. By reconstructing the speed profile of each surveyed driver (309 in total), it was possible to analyze the driver-pedestrian interaction. Data were used to study the driver yielding behavior, to analyze how it is affected by vehicle dynamic constraints, and to identify the significant explanatory variables of a logistic regression model for predicting the drivers’ likelihood of yielding the pedestrian on the different crossing configurations. As a result, significant differences in terms of yielding behavior on the two pedestrian crossing configurations were observed: a higher yielding rate (about 20% higher) and a higher tendency to yield to the pedestrian were reported for the red and white zebra crossing, especially for the most critical conditions of driver-pedestrian interaction. Moreover, the analysis of yielding behavior with respect to vehicle dynamics constraints highlighted that drivers approaching the red and white zebra crossing experienced more opportunities to yield. As a confirmation, logistic regression model showed that the yielding likelihood is significantly and positively affected by the presence of the red and white zebra crossing configuration.

不同人行横道配置下驾驶员屈服行为的实地调查

尽管近年来有报告称道路受害者减少了，但道路交通事故中行人数量的增加仍然是社会关注的问题。这项工作分析了驾驶员在两种不同配置的行人斑马线上的行为：以（1）人行道上的白色条纹（称为“白色斑马线”）和（2）红色人行道上的白色条纹（命名为）标记“红色和白色斑马线”）。尽管后一种配置在当今的城市环境中已相当普遍，但尚无科学证据证明其在调节驾驶员屈服行为方面的实际有效性。这项研究旨在验证红色和白色斑马线对提高人行横道的道路安全性的有效性。一组同步摄像机用于记录驾驶员在接近人行横道时的行为。通过重建每个被调查驾驶员的速度分布（总共309个），可以分析驾驶员与人之间的相互作用。数据用于研究驾驶员的屈服行为，分析其如何受到车辆动态约束的影响，并确定逻辑回归模型的重要解释变量，以预测驾驶员在不同的交叉口配置下屈服行人的可能性。结果，观察到两种行人过路处形态的屈服行为存在显着差异：红色和白色斑马线的行进率更高（约高20％），行人屈服的趋势也更高，特别是在驾驶员和人行互动的最关键条件下。此外，关于车辆动力学约束的屈服行为分析强调，接近红色和白色斑马线的驾驶员经历了更多的屈服机会。作为确认，逻辑回归模型表明，红色和白色斑马线配置的存在显着且正向影响了屈服可能性。
