The Subcommittee on Surrogate Measures of Safety is sponsored by the TRB Committee on Safety Data Evaluation and Analysis (ANB20). The goal of this subcommittee is to examine the suitability and use of surrogate measures of safety to cope with the lack of available crash data. This goal will be pursued by the Subcommittee through the development of a synthesis of existing knowledge and available methods, organizing special conference sessions, and encouraging implementation of existing and emerging methods through guidelines and workshops. This white paper is aimed to: (1) Clarify the concepts, terms, and definitions of surrogate measures of safety, (2) Summarize past research on surrogate measures and point out their weaknesses, (3) Indicate new ideas in this area, and (4) Identify research directions leading to successful development and use of surrogate measures of safety.
