标题：THE INJURY SEVERITY RATE DIFFERENCES IN PASSENGER CARS AND PICK UP TRUCKS RELATED TWO VEHICLE INVOLVED MOTOR VEHICLE CRASHES IN BRITISH COLUMBIA, CANADA
摘要：The effect of large vehicle involvement on motor vehicle crash (MVC) rates and severity has long been a concern in {MVC} analysis literature. Injuries in drivers and occupants are related to several key factors: the mass of the case vehicle and mass of its collision partner and speed of case vehicle and collision partner at the time of the crash. Objective: To evaluate the relative risk of injury occurrence in collisions between picks up trucks (PU) and passenger sedan cars (PS). Methods: Data from the Insurance Corporation of British Columbia (ICBC) crash data base was used to determine {MVC} rates and injury occurrence. Descriptive characteristics of the injury location and injury type were analyzed comparing the Odds Ratios and chi-squares. Results: {PS} occupants received more injuries; Odds Ratio was 2.49 (95% confidence interval: 2.15–2.88). Conclusion: Occupants in {PS} which collide with {PU} were at twice the risk of injuries. Concussion, whiplash, lacerations and abrasion were more frequent in {PS} drivers and occupants than in {PU} drivers and occupants. Overall, {PS} drivers/occupants experienced greater injuries than {PU} drivers/occupants in PU-PS collisions. In this paper, results are shown as odds ratios comparing occupants injuries in {PS} (case group) with occupant injuries in {PU} (control group).
