The Highway Safety Manual (HSM) provides quantitative methods to evaluate improvement alternatives that result in safer, more efficient roadway transportation systems. The HSM has typically been used on Ohio Department of Transportation (ODOT) projects when safety is included in the purpose and need, or a safety concern has been previously identified. However, ODOT has implemented changes to the project development process for planners that involves safety considerations on all projects – big and small.
This addition is called data-driven safety analysis (DDSA). By 2019, planners will need to incorporate safety analysis as part of their alternatives evaluation and decision-making process on major transportation projects due to changes in ODOT’s manuals and guidelines. This includes the Project Development Process (PDP) and the Location and Design Manual. This session, presented by B&N’s Kendra Schenk, PE, PTOE and ODOT’s Derek Troyer, PE, will:
- Explain details of the DDSA changes
- Discuss how these changes affect planners and their process for completing ODOT projects
- Provide examples of how the newly required analysis has been completed on previous projects
