Project Safety Score Tool - Purpose, Scope and Deliverables
14
To maximize the overall safety of the TxDOT system and to institutionalize safety considerations in the planning and design process.
Develop a methodology and tool to evaluate and score a project’s existing design, from an overall safety perspective, as a basis for comparing the score of the proposed design.
Interactive spreadsheet tool used to calculate the safety score for projects with instructions and how-to video.User-friendly guidebook and PowerPoint for the final scoring and evaluation methodology.Branding and Communication plan to help institutionalize message on including safety considerations in the planning and design process TxDOT.

Project Safety Score Tool- What it IS and what it is NOT
17
Purpose is to assess how varying basic design elements influences system safety
• Increase awareness of how design changes can affect safety
• Identify and evaluate design component effect of safety
• Simple and straight-forward decision aid
What IS intended
• A final decision-making tool• Requirement for project approval• Substitute for engineering judgement• Mandate for over-design
What is NOT intended
