However, when crashes are evaluated over too short a period of time (3 years or less), locations may be identified as hot-spots simply due to the random nature of where crashes occur.The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 285: Developing a Guide for Quantitative Approaches to Systemic Safety Analysis describes the research methodology and findings that supported the development of a systemic safety - an alternative (or supplement) to the hot-spot approach - analysis guide and associated training materials.The document is supplemental to NCHRP Research Report 955:Guide for Quantitative Approaches to Systemic Safety Analysis.
