- W14642148 abstract "Hot spot identification (HSID) plays a significant role in improving the safety of a road network. Numerous hot spot identification methods have been developed and proposed in the past. Most of them rely heavily on official crash statistics to conduct HSID. Crash underreporting, along with many other issues, has long been recognized as a threat to the accuracy and completeness of historical traffic crash records. As a natural continuation of a previous study, the paper intends to evaluate the exact influence underreported crashes might have on HSID. To conduct the evaluation, five groups of data gathered from Arizona Department of Transportation (ADOT) over the course of three years are adjusted to account for fifteen different levels of underreporting. Three identification methods are utilized: simple ranking (SR), empirical Bayes (EB) and full Bayes (FB). Various cutoff levels to establish hotspots are explored. Finally, two evaluation criteria are compared across HSID methods. The results illustrate that the identification bias due to crash underreporting may be significant. Comparatively speaking, the crash underreporting has the largest influence on the FB method, and has the least influence on the SR method. Additionally, the impact appears to be positively related with the percentage of the underreported property damage only PDO crashes, but inversely related with the percentage of the underreported injury crashes. This is significant because it establishes that although PDO crashes are seen as the least severe, they have the most significant influence on hot spot identification." @default.
