摘要
驾驶员等待时间阈值是分析礼让行人合理时间的重要参数,是减少非信号交叉口人车冲突,提升道路通行能力的重要条件。通过有序Logistic回归模型研究驾驶员放弃等待时间的影响因素,并基于非集计价格敏感度分析法(KLP)建立驾驶员等待时间阈值模型,利用昆明市驾驶员让行意愿调查数据进行标定。研究结果表明,驾驶员人格类型、性别和教育程度对驾驶员放弃等待时间在统计学上有显著影响;驾驶员年龄、职业和收入对驾驶员放弃等待时间在统计学上无显著影响。驾驶员主观合理等待时间为16.4 s、等待时间阈值为23.2 s,与驾驶员意愿等待时间的50%分位值和85%分位值相吻合。同时,不同人格驾驶员的主观合理等待时间差异较小,而相应的等待时间阈值存在较大差异。
A threshold of waiting time is an important parameter for analyzing reasonable time for drivers yield to pedestrians.It also an important condition for minimizing conflicts between pedestrians and vehicles,and improving road traffic capacity at non-signal intersections.Actual data is obtained from a stated preference survey of drivers in Kunming.Factors affecting the time that drivers would give up waiting are analyzed based on Ordered Logistic model,and a model of waiting time threshold of drivers is established according to the Kishi′s Logit Price Sensitivity Measurement(KLP).The results show that variables such as characteristics of personality,gender,and education level have significant impacts on the time that drivers would give up waiting.But age,job,and income have no significant impact on the time in statistics.The subjective rational waiting time of drivers is 16.4 s,and the waiting time threshold is 23.2 s,which are consistent with 50%and 80%quantile of expectant waiting time of drivers.The subjective rational waiting time has little difference among drivers with different personalities;however,the corresponding waiting time threshold of these drivers varies a lot.
