Abstract:
Objective To study factors influencing injury severity of expressway traffic acci- dents. Methods Data of expressway traffic accidents involving casualties in areas around Hangzhou during 2005-2006 were collected and analyzed by non-conditional simple and multiple logistic regression analysis. Results (1) During 2005-2006, there were 220 traffic crashes involving 327 eases, of which there were 64 deaths (19.6%), 121 severe injuries (37.0%, ISS≥16 points) and 142 slight and mod- erate injuries (43.4%, 1 point≤ ISS≤15 points). (2) Non-conditional simple logistic regression analy- sis showed that risk factors significantly influencing the injury outcomes of traffic accidents included gen- der, weekday, weather, type of collision, vehicle type, driver category, purpose of vehicle use, purpose of travel and crash responsibility. (3) Non-conditional multiple logistic regression analysis manifested that influential factors were gender, type of collision, driver category and crash respensibihty. Conclu- sion Analysis of expressway traffic accidents data helps identify factors influencing injury severity of ex- pressway traffic accidents may provide suggestions for prevention or decrease of expressway traffic acci- dents.
