Triffic environmental factors for road traffic injury in Guilin city

Objective To explore traffic environment risk factors for road traffic injury(RTI) and to provide scientific evidence for RTI prevention and control.Methods RTI data of Guilin city from 2000 to 2009 were collected and analyzed with single factor and multiple factors logistic regression.The traffic environment risk factors for RTI were identified.Results There were 3 603 RTI recorded between 2000-2009 in urban area of Guilin city,of wihich 3 278(90.98%) were attributed to personal factor,250(6.94%) to road factors,and 75(2.08%) to vehicle factors.The results of single factor logistic regression showed that the traffic environment risk factors for road traffic injury were marker line(odds ratio OR=1.363),muddy road(OR=6.976),wet road(OR=10.057),dry road(OR=8.055),traffic circus(OR=4.172),four-round crossroad(OR=1.574),bridge(OR=2.558),ordinary road(OR=0.691),first-class road(OR=3.206),second-calss road(OR=1.602),third-class road(OR=2.321),ordinary road in urban area(OR=0.655),road with street lamp at night(OR=0.469),and day-time(OR=2.061).Multiple logistic regressions revealed that marker line,fouround crossroad,ordinary road,first-and second-class road,ordinary road in urban area,and daytime were traffic enviroment risk factors for RTI in Guilin city.Conclusion The daytime,marker-line,four round crossroad,ordinary road,first-and,secondclass road,and ordinary city road are closely related to the occurrence of RTI in Guilin city.Relevant government departments should carry out traffic safety education among road users and improve road traffic environment to reduce the occurrence of RTI.
