abstract: OBJECTIVE
  To analyze the characteristics of road traffic accidents in Bao'an District, Shenzhen from 2004 to 2011, and to provide scientific basis for  the prevention and treatment of traffic accidents.
  
  
  METHODS
  The traffic injury cases recorded by Shenzhen traffic police from 2004 to 2011 were analyzed,  including the time (year, month, date); the space (crossings and road segments, road type); the injury of patients (injuries, death).
  
  
  RESULTS
  A total of 422  730 accidents from road traffic occurred in Bao'an District, Shenzhen from 2004 to 2011, with 63 809 people injured and 2 790 people died, and the mortality  ratio was 22.87:1. Traffic accidents occurred in Bao'an District showed an increasing trend, especially in 2010, and the highest number up to 90 358, while  the most deaths occurred in 2007, up to 473 people. As to the single month, the highest traffic accident rate was in August, accounting for 9.77% of the  total, while the lowest was in February, accounting for 5.39% of the total; mortality rate in December reached 9.02%. As to one single day, the peaks of  accidents occurred in two periods: 9:00-11:00 and 15:00-18:00, and 3:00-6:00 had the smallest number. Traffic injuries often occurred in the  intersection, straight line, main road and the section only marked marking.
  
  
  CONCLUSIONS
  According to the characteristics of regional traffic injury, we  should enhance the populace traffic safe awareness, efficiently arrange the human resources, such as emergency personnel, traffic management  personnel, set scientific preventive measures, and modify the emergency system and service mode. All of these are essential measures for the prevention  and control of traffic injuries.
