The objective of hot spot identification (HSID)is to identify transportation system locations(road segments, intersections, interchanges, ramps, etc.) that possess underlying correctable safety problems, and whose effect will be revealed through elevated crash frequencies relative to similar locations.

potential for accident reduction, as the difference between the observed and expected number of crashes at a site

proposed that blackspots should be defined as those sites whose accident frequency is significantly higher than expected at some prescribed level of significance

proposed the road sites selected for treatment should maximize the expected total accident reduction by treatment.
