TRB’s National Cooperative Highway Research Program (NCHRP) Research Results Digest 329: Highway Safety Manual Data Needs Guide is designed to help potential users of the 1st edition of the Highway Safety Manual (HSM) anticipate the data needs for using the HSM. The guide focuses on the data needed to use the HSM Part C methodologies for rural two-lane highways, rural multilane highways, and urban and suburban arterials. The guide provides information designed to help potential HSM users assess whether their existing data sources contain the data needed to apply the HSM safety prediction methodologies to highways of interest.
