[Objective] To understand the level and trend of traffic accidents in a city from 1994 to 1998. [Methods] The epidemiological analysis of five years’ traffic accidental injury statistics of a city public security department was conducted and the potential years of life lost (PYLL) of different age groups were compared. [Result] With the increase of automobile ownership and petrol consumption, the incidence of traffic accidents in this city has been on the rise. However, the annual death toll from traffic accidents has remained at a steady level. Among drivers, riders, cyclists and pedestrians, the number of males and the number of accidents were higher than those of females. The main targets were cyclists and drivers. Urban traffic accidents were significantly higher than the suburbs, the seasonal and monthly trends are not obvious. The number of traffic accidents per hour occurred at 8: 00-17: 0 0 on the same day in urban areas, while the trend of death numbers showed a bimodal distribution with peaks at 5: 0-0: 0: 0 and 2: 1 : 0 0 ~ 2 3: 0 0, while in the suburbs, the changes of the two are relatively flat and the central tendency is not obvious. [Conclusions] It is necessary to carry out health promotion work for different traffic participants, strengthen the safety management during dangerous times and sections, improve the traffic and traffic facilities, prevent and control the occurrence of traffic accidents
