An Empirical Analysis of Driver Injury Severities in Work-Zone and Non-Work-Zone Crashes Involving Single-Vehicle Large Trucks

This study investigates the contributing factors influencing the driver injury severity of single, large truck crashes in work zones, as Florida ranks among the states with the highest rates of work-zone crashes involving large trucks. Using work-zone and non-work-zone crash data from 2011 to 2019 (inclusive), driver-injury severities in single-large trucks crashes were studied using random parameters logit models that allow for possible heterogeneity in the means and variances of parameter estimates. The model findings include the need for various policy-related safety countermeasures including revisiting traffic control plans for large trucks.
