Objeetive To analyze traffic accidents involving pedestrians in Chongqing from 2000 to 2006 so as to understand injury characteristics of the pedestrians. MethodsThe data of pedestrian road traffic crashes and injuries in three districts including one district in downtown,one in suburb and one in county of Chongqing from 2000 to 2006 were collected from road traffic crash and road traffic injury database to analyze severity of crashes,casualties,action and location of pedestrians in crashes. Results The road crashes led to 7 934 pedestrian injuries (24.74%) and 867 pedestrian deaths (49.46%).Intensity of the pedestrian road crashes in rural areas was higher than that in downtowns and suburbs.Of all pedestrian casualties,57.91% were due to illegally crossing the driveway,and 15.43% of the casualties were on the crosswalk.Most of the casualties occurred on the main roads,the third class highways and second main roads in Chongqing.But serious crashes occurred on the first and second class highways and substandard highways,which led to average 3.17,4.13 and 5.42 deaths,respectively.Pedestrians accounting for 52.46% of the total severe injuries were more than the proportion among the minor to moderate injuries.Head injuries were the most common for the pedestrians and chest injuries were also usual among the severe injuries. Conclusions The intensity of pedestrian road crashes is higher than that of other crashes,especially in rural areas.It should be noticed that the main injuries of the pedestrians are head injuries,which is mainly resulted from illegally crossing driveway.It is worth noticing that a rather high proportion of pedestrians are impaired on the crosswalks,indicating that we should pay more attention to protect right of the pedestrians on the crosswalks during transportation law enforcement and safety education in the future.

ObjectiveTo study the characteristics and risk factors of traffic injuries among the adolescents (0-19 years old) in the urban and rural areas of Chongqing and discuss the preventive strategy. MethodsData of road traffic crashes and injuries involving 0-19 years old adolescents over a seven-year period (2000-2006) in three districts of Chongqing was picked up from Road _Traffic Crashes and Injuries Database. Epidemiological characteristics of the traffic crashes and injuries among 0-19 years old adolescents were analyzed and differences between rural and urban areas were studied. ResultsFrom 2000 to 2006, both incidence rate and mortality rate peaked in the urban fringe area were 95.43/100 000 and 3.44/100 000 respectively. Traffic accidents in the suburbs and counties had the highest injury extent, with mortality rate of 9.06% and severe injury rate of 17.33%. Brain injuries were the primary cause of death. Among the victims, 62.7% were the pedestrians, of which 20.72% bore equal responsibility because of disobeying traffic signals, suddenly walking across roads and not walking along the sidewalk. Ninety percentage of the traffic accidents occurred in the sections with no traffic signals or traffic control system. ConclusionIt is important to enhance the traffic safety consciousness of teenagers and children, strengthen preventive measures in fringe areas and rural areas and improve the emergency medical system in rural areas to provide the teenagers and children with a safety traffic environment.

Objective To establish a road traffic crash (RTC) & traffic injury (RTI) database database with scientific and reasonable structure. Methods ( 1 ) A set of scientific and standard RTC&RTI survey form was made and a software for collection of data on RTC&RTI developed. (2) The general data on RTI&RTI of China was obtained from traffic management departments of China and the data of some districts in Chongqing from 2000 to 2006 were obtained. All the data were input into the database for analysis. Results A TRC&RTI database software V1. 0 was developed based on the survey form. The input items included data about the areas where the accidents occurred, the general situation of the specific accident, the road conditions, the accident causes and responsibilities, the vehicle and the injury to persons. We obtained the RTC and RTI data of China during past 13 years and collected data on 33 987 cases of RTC and 52369 RTI of four districts in Chongqing. The RTC&RTI database was established. Conclusions The database has involved detailed data of general road crashes and injury as well as individual crash, which provides a good support for further study of RTC and RTI.
