摘要

本研究探讨了驾驶员在无信号人行横道让行行为的相关因素,并利用逻辑回归开发了让行预测模型。它考虑了描述驾驶员属性、行人特征和人行横道并发条件的变量对屈服响应的影响。特别考虑了形成潜在产量阈值的“车辆动力学约束”。相似之处在于驾驶员对信号交叉口的“琥珀色”指示的反应。logit模型是根据在北卡罗来纳州两个没有信号的中间街区人行横道收集的数据开发的。数据包括对两种行人安全处理的“之前”和“之后”观察,一种是街道内的行人过街标志,另一种是行人驱动的道路警示灯。分析表明,司机更有可能对那些快步走向人行横道的自信行人让步。反过来,更高的速度、减速率和车辆成排行驶时,屈服概率也会降低。治疗效果被证明是显著的,并增加了司机的屈服倾向,但其有效性可能取决于行人是否激活治疗。本研究结果为无信号交叉口行人和车辆的复杂相互作用提供了新的见解,并对未来驾驶员屈服行为预测模型的研究具有重要意义。所建立的logit模型可以为在微仿真建模环境下表示驾驶员屈服行为提供依据。

Event-Based Modeling of Driver Yielding Behavior at Unsignalized Crosswalks.

This research explores factors associated with driver yielding behavior at unsignalized pedestrian crossings and develops predictive models for yielding using logistic regression. It considers the effect of variables describing driver attributes, pedestrian characteristics and concurrent conditions at the crosswalk on the yield response. Special consideration is given to 'vehicle dynamics constraints' that form a threshold for the potential to yield. Similarities are identified to driver reaction in response to the 'amber' indication at a signalized intersection. The logit models were developed from data collected at two unsignalized mid-block crosswalks in North Carolina. The data include 'before' and 'after' observations of two pedestrian safety treatments, an in-street pedestrian crossing sign and pedestrian-actuated in-roadway warning lights.The analysis suggests that drivers are more likely to yield to assertive pedestrians who walk briskly in their approach to the crosswalk. In turn, the yield probability is reduced with higher speeds, deceleration rates and if vehicles are traveling in platoons. The treatment effects proved to be significant and increased the propensity of drivers to yield, but their effectiveness may be dependent on whether the pedestrian activates the treatment.The results of this research provide new insights on the complex interaction of pedestrians and vehicles at unsignalized intersections and have implications for future work towards predictive models for driver yielding behavior. The developed logit models can provide the basis for representing driver yielding behavior in a microsimulation modeling environment.
