Safety and Travel Time Reliability: Analyzing Large-Scale Truck Involved Crashes

This project is split into two phases. Phase 1 of this project focuses on investigating the associations between injury severity and unsafe pre-crash driving behaviors (both intentional and unintentional) of passenger vehicle and truck drivers. From the manner of collision stand-point, head-on collisions accounted for 26% of all motor-vehicle involved fatal crashes. Given the importance of head-on collisions, Phase 2 of this project focuses on investigating the degree of injury severity sustained by drivers involved in head-on collisions. Specifically, the authors are interested in how at-fault driver behavior and characteristics relate to injury outcomes of not-at-fault drivers. Research activities focused on five key objectives: (1) To quantify the associations of unsafe driving behaviors (specifically intentional and unintentional actions of truck and passenger vehicle drivers) with injury severity outcomes in passenger vehicle-truck collisions (Phase 1); (2) To explore unobserved heterogeneity in associations of injury severity with unsafe pre-crash behaviors, while controlling for driver, vehicle, and roadway factors (Phase 1); (3) Simultaneously investigate the degree of injury severities sustained by individual drivers involved in head on collisions (Phase 2); (4) Distinguish the differential associations of correlates on resulting injury severities of two drivers with respect to fault status designation in head on collisions (Phase 2); and (5) Disentangle the anticipated non-normality of joint error distributions and unveil the complex forms of stochastic dependencies between the residuals (Phase 2).
