FHWA-NHI-380070 Highway Safety Manual Practitioners Guide for Geometric Design Features (2-Day) MTS


This course includes both 2-lane and multi-lane highways and provides a proven methodology for the safety performance of geometric design decisions in a like manner to that of predicting capacity and level of service based upon large scale definitive research. The crash prediction models for total crashes and cross-section related crashes based upon lane width, shoulder width, roadside hazard, traffic volume (exposure) and other characteristics are presented. Examples of safety performance prediction are presented for highway segments and intersections.
Discussion of research and the interactive effects of lane and shoulder widths, hazard rating, and access density (driveways) on safety performance are presented. Each student receives a copy of the "Safety Effects of Highway Design Features" manual.
IMPORTANT: Participants should bring a scientific notation calculator as the course involves calculating decimal value to decimal power for crash prediction values.


Upon completion of the course, participants will be able to:
  • Recognize the safety effects of geometric design features
  • Predict the safety performance of geometric design features
  • Compare alternative designs based upon an assessment of the safety effects of geometric design features


State and local highway engineers and consultants involved in the design of both two-lane rural and/or multilane highways.
