Non-Recurrent Congestion Caused by Freeway Accidents: Which Factors Are Critical?

When considering the extreme difficulty of estimating accident likelihood, the most important potentially soluble factor in the development of congestion management strategies is to identify the factors affecting non-recurrent congestion caused by accidents. Most of all the identification of such factors is required as a basic information for the purpose of accident management strategies as well as for the purpose of congestion management strategies. The objective of this paper is to identify causal factors affecting non-recurrent congestion. To perform this objective, a case study to quantify non-recurrent congestion caused by accidents in terms of total delay is demonstrated by using a previously developed method based on historical inductance loop detector data from six major freeways in Orange County, California. From the case study results, potential factors contributing to non-recurrent congestion are identified by using a Cox model.
