Highway safety manual introduction

 · 1. Introduction to the Highway Safety Manual. The AASHTO Highway Safety Manual (HSM), published in , represents the culmination of 10 years of research and development by an international team of safety experts, academics, and practitioners. The HSM was envisioned as a companion document to and modeled after the well-known Highway Capacity Manual. What is the Highway Safety Manual? The Highway Safety Manual (HSM) introduces a science-based technical approach that takes the guesswork out of safety analysis. The HSM provides tools to conduct quantitative safety analyses, allowing for safety to be quantitatively evaluated alongside other transportation performance. The Highway Safety Manual (HSM) is the premier guidance document for incorporating quantitative safety analysis in the highway transportation project planning and development processes.

material provides a snap shot of highway safety statistics, a brief introduction to the AASHTO Highway Safety Manual, and shows how safety can be incorporated into practice through proven safety countermeasures and low cost safety improvements. Examples and case studies applying the Highway Safety Manual principles and techniques, including Crash. The Highway Safety Manual (HSM) is the premier guidance document for incorporating quantitative safety analysis in the highway transportation project planning and development processes. The Highway Safety Manual (HSM) is the premier guidance document for incorporating quantitative safety analysis in the highway transportation project planning and development processes. The HSM, developed by AASHTO and first published in with a supplement for freeways published in , presents contemporary scientific methodologies for estimating safety performance of highways and streets to inform the highway transportation decision-making process.
