Abstract:

This study collected and analyzed the wrong-way crashes data for a six-year time period, from 3 2004 to 2009, on Illinois freeways. The objective of the study was to characterize the statistical characteristics of wrong-way crashes from these three aspects: crash, vehicle, and person. The temporal distributions, geographical distribution, roadway characteristics, and crash characteristics were analyzed for wrong-way crashes. The wrong-way driver demographic information, driver physical condition, and driver injury severity were analyzed for wrong-way drivers. The vehicle characteristics, vehicle operation, and collision results were analyzed for wrong-way driving vehicles. General statistical characteristics of wrong-way crashes were analyzed, and the findings revealed that a large proportion of wrong-way crashes occurred during the weekend from midnight to 5 a.m. Approximately 80 percent of wrong-way crashes were located in urban areas. Nearly 70 percent of wrong-way vehicles were passenger cars. Approximately 60% of wrong-way drivers were driving under the influence (DUI). Of those, nearly 50% were confirmed to be impaired by alcohol, about 5% were impaired by drugs, and more than 3% had been drinking. Wrong-way entry points were analyzed for different interchange types as well. Compressed diamond interchanges, SPUI, partial cloverleaf interchanges, and freeway feeders had the highest wrong-way crash rates (wrong-way crashes per 100 interchanges per year). The contribution of this study was a new method to predict the possible wrong-way entry points and rank the high-frequency crash locations for field reviews based on the number of recorded or estimated wrong-way freeway entries.
