Abstract
This paper compared total trends of traffic crash frequency and severity at High Crash Location (HCL) intersections during three study periods in Nevada, US. The paper provided an in-depth inspection in selecting and ranking HCL intersections by the total score and Potential for Safety Improvement (PSI). The study indicates that the rank of HCL intersections by the total score is very different from ranks by PSIs. Intersections with high PSIs might not be qualified on the list of top-ranked HCL intersections with the underestimated attention, while intersections with low PSIs, but high total scores might be paid attention overestimated. The study reflected that potential rooms for crash mitigations are limited for intersections with negative PSIs but qualified as HCL intersections by the total score. How to select and rank HCL intersections plays a very important role in directing traffic safety funding allocation and most mitigating traffic crashes.
