Developing a Guide for Quantitative Approaches to Systemic Safety Analysis
Highway agencies have traditionally managed the safety improvement process by identifying
and correcting high-crash locations (“hot-spots”), where concentrations of crashes and, often,
patterns of crashes of similar types, were found. 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.
