Abstract

Identi? cation of hot spots is an important activity for improving the overall Safety of roadway networks. A central issue in comparing HSID methods is the development and selection of quantitative and qualitative performance measures or criteria. In this research, The seven commonly applied HSID methods (accident frequency (AF), equivalent property damage only (EPDO) based the coefficients of the PIARC, P-value (Islamic Republic of Iran Ministry Roads and Urban development), accident rate (AR), combined criteria, empirical Bayes (EB), societal risk-based) were compared against six robust and informative quantitative evaluation criteria (the site consistency test, the method consistency test, the total rank differences test, the total score test, sensitivity test and specificity test). These tests evaluate each method performance in a variety of areas, such as efficiency in identifying sites that show consistently poor Safety performance, reliability in identifying the same Hotspots in subsequent time periods. To evaluate the HSID methods, three years of crash data from the Jiroft-Kerman road were used. Analytical Hierarchy Process (AHP) method has been used for determination the importance coefficients of evaluation tests and as a result, showed that the total rank differences test is the most appropriate test. Also the quantitative evaluation tests showed that the EB method is the most consistent method for identifying Hotspots and accident frequency, accident rate and combined criteria methods after EB method cause the identification of Hotspots similar, that they have similar performance and their evaluation results is the same, have the best performance. Following these methods, the P-value, equivalent property damage only based the coefficients PIARC, and societal risk-based respectively. Societal risk-based method performed worst in all of the tests. It should be noted that advantages associated with the EB method were based on crash data from one the road Iran country and the relative performances of HSID methods may change when using other crash data. However, the study results are consistent with earlier? ndings.
