Background and aims: Crashes and its related human and financial losses have been turned to be one of the challenges of human societies so that road death statistics shows a high number of 219172 in Iran from 2005 to 2014.

Methods: In this research, using global and valid Road Safety Development Index (RSDI) that illustrates general roads safety condition and consists of nine effective parameters, roads safety in Iran and 10 countries of southeast of Asia was analyzed from March 2010 to March 2011. Considering the charechtristics of the parameters, two scaling methods entitle "Simple Average Weighting" and "Subjective Weighting" were used.

Results: Iran's scores were 48.35 and 45.29 for Simple Average Weighting and Subjective Weighting respectively and was in middle level of safety also it ranked as the fourth country among 11 studied ones in 2011. Although some parameters got better, comparing three last years, in many of them especially number of death, crashes and drivers' behavior conditions were unacceptable. The important point is that Subjective Weighting method acts more accurate than Simple Average method, respects to considering change of weights according to importance and their role comparing.

Conclusion: The research's findings illustrated that Iran moved toward middle level of road safety from lower levels in last years. However, regards to ranking and scores resulted from indexes it is not in desirable conditions.
