Application of macroscopic safety models for hot zone identification

Macroscopic safety research provides important insight into dealing proactively with road safety problems in the transport network. This research explores the need to develop and use macroscopic safety models in Australia, especially for network screening. Using road crash data from Melbourne, Australia (2010-2012), safety performance functions (SPFs) are developed for total, serious injury and minor injury crashes. Potential for Safety Improvement (PSI) is adopted as the measure of the crash risk. The developed PSI’s are used to identify the various hot zones (high-risk crash zones) in the Melbourne transport network.
