Abstract

This study presents the results of an analysis on the impact of increased law enforcement on truck driver-at-fault crashes and identifies corridors that would make viable candidates for the Oregon MCSAP program. This was accomplished through a descriptive analysis of collected inspection data and Oregon crash data. Next, the safety performance of the program was determined by generating a safety performance function and estimated a crash modification factor. The safety performance analysis determined that the MCSAP program had a substantial impact on reducing truck driver-at-fault crashes. Using the crash modification factor, as well as estimates of the effects on law enforcement on truck driver-at-fault crash frequency, a benefit/cost analysis was conducted on several candidate corridors/segments. Three segments were identified as viable candidates for program expansion. Lastly, a survey was administered to law enforcement in Oregon to gauge their perception and willingness-to-adopt such a program in their jurisdiction. The project report provides ODOT with a comprehensive summary and recommendations
