Introduction: Traffic accidents in Iran is the second factor of death whereas, traffic accidents are the ninth cause of death in the world. Therefore, this study has been conducted for epidemiologic assessment of fatal traffic accidents in the Khuzestan province.
Methods: This is a desc riptive-analytical study which is performed from March to February 2010 through collection of existing documents of all victims died due to accidents and for obtaining a burial permit their bodies were referred to the Forensic Medicine Centers of Khuzestan cities. Data was analyzed by SPSS software.
Findings: Of 7856 investigated cases from 24 cities in Khuzestan province, Totally 1,514 persons died due to traffic accidents. Most of victims (35 percent) were 15-30 years old. Final cause of death in 45 percent of victims was head trauma. Majority of fatal accidents caused by cars in 57 percent and occurred on suburban roads. The highest percentage of traffic accidents victims were car passengers and motorcyclists with 46.5 and 21.5 percent, respectively.
Conclusion: According to the high percentage of fatal accidents in the country and province, to resolve this problem is necessary the using appropriate scientific programs and investment for reduction of accidents and improving the roads safety.

INTRODUCTION: Road traffic accidents, which are predictable and preventable events, have emerged as the serious health problems due to high costs for developing countries. The study of the epidemiology of traffic accidents provides valuable information for identifying research priorities. This study aimed to evaluate the epidemiology of road traffic accidents in Iran in 2013.
METHOD: In this cross-sectional study, all traffic accidents which the injured (about 189329) referred or admitted to the public or private hospitals were selected and studied by using data from accidents record system in 2013. The rate of pedestrian accidents was estimated per ten thousands. Also, for data analysis Excel-2010, Stata-11 and GIS were used.
FINDINGS: In this study, all drivers (129506 male and 59823 female) who were injured in road accidents were studied. The results showed that men involved in more traffic accidents than women (68/40% and 31/60% respectively); also, most affected people were in the age group of 20 to 24 years, and most accidents occurred on the street (55%).
CONCLUSION: Damages caused by traffic accidents in drivers are very high in the country and prevention is essential. Therefore, identifying factors with relevance to traffic accidents will be helpful in order to make effective interventions.
 

INTRODUCTION: According to the official statistics, a high rate of road traffic deaths occurs during the transportation of the injured and in medical centers. The way of transporting the injured to the medical centers, the standard time of dispatch and timely treatment in the hospitals, the land use planning of medical centers and rehabilitation are the three missing links of the post-event phase. Therefore, the researchers aimed to assess the effect of rescue and relief services on the severity of traffic accidents in this study.
METHODS: This applied research was conducted based on an exploratory mixed method. The statistical population in the qualitative section included Amin Police Academy professors, experts of both Red Crescent Society (RCS) of Tehran province and Tehran Emergency Medical Service (EMS), who were selected via purposive sampling method. In the qualitative section, the theme analysis method was used and analyzed by using Maxqda-2020 software. The statistical population of the quantitative part included excellent accident experts of 28 districts of Tehran and experts of the RCS and EMS of Tehran province in a stratified random method. In the following, confirmatory factor analysis using structural equation modeling method was used and analyzed with SmartPLS3 software. 
FINDINGS: The dimensions of the impact of rescue and relief services on the severity of traffic accidents from the perspective of Red Crescent Society and Emergency Medical Services experts included equipment (31.077), land use planning (25.610), expertise (23.598), and education (8.243). The most marked impact was related to equipment, and the least impact pertained to education. Furthermore, the dimensions of the effect of rescue and relief services on the severity of traffic accidents from the perspective of accident experts included equipment (42.009), land use planning (34.419), education (33.770), and expertise (8.951). The greatest impact was related to equipment, and the least effect pertained to expertise. In addition, the factor loadings of all dimensions were more than 0.5 being significant at the 0.95 level.
CONCLUSION: Strengthening and developing equipment, land use planning balanced with the geography of missions, and continuous specialized training of rescue and relief of RCS and EMS experts will positively reduce the severity of traffic accidents in the country.
