Briefly explain the steps in the roadway safety management process as outlined in the Highway Safety Manual.
What will be an ideal response?
The HSM recommends that the Roadway Safety Management process should
involve the following steps:
- Network Screening – In this step, sites at which the potential for
reducing average crash frequency exists are identified and ranked,
through a review of the transportation network
- Diagnosis – In this step crash patterns are determined through the
collection and analysis of historic data, and evaluation of site
conditions
- Select Countermeasures – This step involves determining probable
crash related factors at a site and selecting countermeasures that will
be effective in reducing crash frequency.
- Economic Appraisal – This step involves conducting an appropriate
economic analysis to identify specific projects that are economically
justifiable.
- Prioritize Projects – In this step, the projects that are economically
justifiable at specific sites and across multiple sites are prioritized with
respect to their potential to achieving safety objectives within the
available budget. Prioritization factors may include low cost, mobility
enhancement potential or reduced negative environmental impact.
- Safety Effectiveness Evaluation – In this step the selected
countermeasures at a site or multiple sites are evaluated to determine
how effective they are or would be in reducing annual crash frequency
or severity.
