Abstract:

This study explores the effects of pandemic-related trucking relaxations on freight safety in Oregon. A historical review of trucking relaxations before and during the pandemic is conducted and compared. Using traffic volume levels and key pandemic dates, three time periods were chosen for analysis: (1) pre-pandemic, (2) a low VMT pandemic period with trucking relaxations in effect, and (3) a normal VMT pandemic period with trucking relaxations in effect. These periods were considered for a descriptive analysis in which a series of proportions tests were conducted to identify overrepresentations. Following the descriptive analysis, a series of freight safety behavior models were developed to describe three key safety performance measures: crash frequency, crash rate, and injury severity. In addition to disaggregate data models and transferability tests, pooled models were developed to determine the effects of the time periods on these safety measures. Results from the analysis are compared across time periods (relative to the pre-pandemic period) to determine if there were significant changes in the periods coinciding with trucking relaxations. This study concludes by providing a comprehensive conclusion and recommendations.
