Road safety performance evaluation and policy making by data envelopment analysis: A case study of provincial data in Iran

Considering the need to invest in road safety programs, an eciency analysis onimplemented countermeasures is required. the system presented in this study is designed toevaluate the eciency related to measures annually implemented throughout 30 provincesof iran, specically in 2008 and 2009. the model calculates a relative ineciency indexfor each province and in each year, using the data envelopment analysis (dea) method.each province in each year is dened as a decision making unit (dmu) in dea analysis.the ineciency index is dened as the proportion of the weighted sum of road fatalityrisk indices to the weighted sum of road safety performance indicators. the ineciencyrate for each dmu must be minimized by either decreased fatality indices and/or increasedsafety measures to an optimal extent. using a dual model of the main dea model for eachdmu, a target setting task can be conducted by identifying the benchmarks as the leadingentities. moreover, some discussions are provided for the results concerning the ecientunits and the two-year comparison analyses
