| 摘要： | Incidents significantly impact the performance of urban freeway systems. Because of this, transportation agencies are working to gain a solid understanding of incidents and their associated characteristics. In this research effort, a database of incidents occurring in the Hampton Roads, Virginia region was analyzed to identify (a) incident characteristics that significantly influence accident clearance duration, and (b) probability distribution functions well-suited to modeling accident clearance duration. The results of analysis of variance tests indicate that the time-of-day, day-of-week, type of incident responder (i.e. police, emergency medical services, etc.), number of vehicles involved, and the types of vehicles involved (i.e. passenger vehicle, truck, etc.) all have a significant influence on accident duration. However, it was found that the Weibull and lognormal distributions, often used to model incident duration, are not well-suited to model accident clearance duration. |
