Analysis of automotive crash alarm system based on traffic rescue time

Abstract

Objective To analyze the emergency rescue situation of casualties in traffic accidents according to traffic accident depth investigation and discuss the difference of various road environmental accidents and rescue time in Chongqing area so as to provide the theoretical basis for the application of automobile collision automatic alarm system. Methods Information on 105 traffic accidents in Chongqing in 2015 was collected and statistically analyzed, including the time, weather, regional distribution, types, rescue time and damage. Results There was higher incidence rate of accidents in summer and in the main urban regions. Personnel damage in expressway accidents was more severe than that in urban roads (P<0.05). The rescue time of urban road accidents was (25.27±13.68)min, and that of highway accidents was (39.26±24.74)min, with statistically significant difference (P<0.05). The damage was related to the collision speed (Spearman, R=0.616, P<0.05). Conclusion In Chongqing, the rescue time of highway accidents is longer than that of urban road accidents, and personnel damage in highway accidents is more serious than that in urban roads. Key words: Traffic accident rescue; Automatic collision alarm; Rescue time; Injury risk
