In order to reduce the number and the effects of traffic accidents on a roadway, various countermeasures are taken into consideration. The first step to decide the proper countermeasures is identifying Accident Black Spots (ABS) and then improving the site regarding the different type of the countermeasures to reduce the effect of the traffic accidents. As well as many methods used to identify the ABS in literature, network screening technics, that simple ranking, sliding window and peak searching, are defined in Highway Safety Manual published by AASHTO in 2010. In these technics, there are various performance measures like average crash frequency, equivalent property damage only, etc. to rank the roadway segment. Based on the ranking, ABS are identified and prioritize to decide and implement the countermeasures.
