Objective Traffic crashes information presented by the I.R. of Iran's significant information sources was compared with in-use models of the USA and different Asian countries.

Methods Information on traffic crashes epidemiology was investigated and collected directly in the organisations by trained experts of the study using questionnaires verified in validity and reliability. Afterwards, information collecting and traffic injury surveillance systems of some countries were explored and after being compared with current information recording systems of the I.R. of Iran qualitatively, differences and probable weaknesses were clarified.

Results Traffic Police collects five major parts of the mentioned model in the 113 and 114 Com from format. Emergency Medicine Management Center is responsible for providing some parts of the injury surveillance system's information—which are some parts of the mentioned model—in the 115 EMS mission form format. In comparison with the American traffic records model, records of the I.R. of Iran's traffic police are similar to the model in the crash and vehicle information components completely. They are also similar in all details of the roadway and driver information components except for the traffic volume and conviction history. In comparison with some Asian countries, in the core minimum data on any case of injury class, the diagnosis of injury-related disease in not based on ICD and AIS in the I.R. of Iran.

Conclusions Traffic injury information gathering system needs utilising ICDs and AISs and—like other countries in the region—a unit format and language on traffic injuries records.
