عوامل انسانی موثر در شدت حوادث ترافیکی مرتبط با عابران پیاده در تهران

Background and aims: More than 40 percent of deaths of pedestrians in traffic accidents happen in Tehran. The aim of this study was to determine the impact of human factors was associated with an increased intensity of pedestrian traffic.   Methods: In this cross-sectional study, 6323 traffic injuries and 99 traffic deaths resulted from traffic accidents in pedestrian during 2013 in Tehran were investigated. Data was extracted from traffic police databases and in Tehran. In analytical analysis, logistic regression model was used to control for possible confounders   Results: In studied accidents, 4070 (63.5%) and 2335 (36.5%) of injured or died pedestrians were male and female, respectively. The mean age of injured pedestrians was 39.15 ± 19.47 years and the mean age of guilty drivers was 34.75 ± 12.38 years. The final model showed that gender, age, pedestrian position and fault, and type of driver's license are correlated to the dependent variable. The events leading to the death was significantly higher in men, pedestrians standing next to the roadway, pedestrians fault and drivers with grade 1 of driver license.   Conclusion: Human factors had much role in the severity of traffic accidents related to pedestrians in Tehran. These factors have a high correlation with environmental factors, and vehicles. More researches is needed to specifying mechanisms of effect of these factors in traffic accidents related to the pedestrians and designing strategies for promotion of traffic culture and safe behaviors in drivers and pedestrians.
