Analyzing the Safety Impact of Crash-Prone Drivers in Louisiana

Abstract (Summary)

Crash-prone drivers should be effectively targeted for various safety education and regulation programs because their involvement in crashes presents a big adverse effect on highway safety. To improvement highway safety from the key element of transportation system, this research investigates crash-prone driver problem in Louisiana. Through analyzing the crash data of seven years from LADOTD, this study identifies the gravity of the problem and characteristics of crash-prone drivers and crashes they committed.

The analysis results show that quite a few drivers repeatedly had crashes; seven drivers had 13 crashes in seven years; and the maximum number of crashes occurring in a single year to a single driver is eight. Actually, the 5% of drivers who had multiple crashes were responsible for 35% of the crashes that occurred in the seven years in Louisiana. Crash injury rate is also higher for drivers with multiple crashes. The results demonstrate that young male age 15 to 24 and old female age 65 to 74 have the highest recurring crash potential, and male crash-prone drivers are generally more likely to involve in more crashes than female crash-prone drivers. The probability of having crashes in any given year is closely related to a driver’s crash history; The results of three probability matrix models give quantitative estimate on crash risk predict at three time interval modeling scenarios. The developed probability predicting model can be used for estimating an individual future crash risk.

Based on the results, several suggestions are made on how to improve roadway safety through reducing crashes committed by drivers with much higher crash risk as identified by the analysis.
