Safety Prediction Models for Six-Lane and One-Way Urban and Suburban Arterials
The
Highway Safety Manual (HSM) provides a predictive method for two- and
four-lane urban and suburban arterial facilities with both undivided and divided cross-sections.
The manual does not cover arterials with six or more lanes or one-way streets.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 318: Safety Prediction Models for Six-Lane and One-Way Urban and Suburban Arterials
documents a safety prediction method for six-or-more-lane and one-way urban and
suburban arterials, as well as intersections located on these facilities, that is suitable for
incorporation in the HSM.
Supplemental to the document are a
User Manual and a
Prediction Model Spreadsheet.
