摘要

本研究探讨了白天和夜间发生的与超速有关的撞车事故中影响伤害严重程度的因素的差异。进行了两个对数似然比测试来验证是否应该将白天和夜间分类的超速相关碰撞分别建模。结果表明,独立建模是必要的。利用美国2018 - 2020年的数据,建立了两个具有均值异质性的相关随机参数序probit模型。模型估计结果表明,城市区域、速度限制、年轻和老年驾驶员存在时间不稳定性。角度碰撞、正面碰撞、十字路口、下坡、超速、酒后驾驶和摩托车在两种车型中都具有统计学意义,碰撞严重程度增加。随机参数之间的相互作用和异质性效应也被报道。例如,大型卡车超速行驶更有可能增加严重受伤的可能性。

Investigating the difference in factors influencing the injury severity between daytime and nighttime speeding-related crashes
This study investigates the differences in the factors affecting the injury severity of speeding-related crashes occurring in the daytime and nighttime. Two log-likelihood ratio tests are conducted to validate whether speeding-related crashes classified by daytime and nighttime should be modeled separately. The result proves that separate modeling is necessary. Two correlated random parameter order probit models with heterogeneity in means are conducted using the data collected from 2018 to 2020 in the United States. Model estimation results show that urban areas, speed limits, and young and older drivers are temporal instability. Angle crashes, head-on crashes, intersections, downhill, exceeding the speed limit, drunk driving, and motorcycles are statistically significant in both models with an increased crash severity. Interaction and heterogeneity effects between random parameters are also reported. For instance, large trucks driving above the speed limit are more likely to increase the probability of severe injury.
