Presentation Transcript

  1. The Use of Three-Dimensional (3-D) Visualization in the Road Safety Audit (RSA) Process

  2. What is an RSA? • Formal safety performance examination • Considers the safety of all road users • Independent multidisciplinary team

  3. Why an RSA? Begin with the end in mind… Reduce the number and severity of motor vehicle crashes.

  4. The 8-Step RSA Process

  5. Benefits of Using 3-D Visualization The 3-D model enables members of the RSA team who are not proficient at reading and interpreting roadway design plans to grasp the proposed improvements and identify potential safety concerns.

  6. 3-D visualization brings a static design to life Benefits of Using 3-D Visualization

  7. Benefits of Using 3-D Visualization The 3-D model can be used to illustrate exactly how the roadway environment will be affected by signs, structures, guardrail, and other key features that are supplemental to the roadway itself.

  8. Benefits of Using 3-D Visualization The 3-D model allows users to view the proposed conditions from any number of vantage points, which may reveal issues not otherwise obvious from a review of standard 2-D plans.

  9. Benefits of Using 3-D Visualization The 3-D model can be used by the RSA team to provide visual support of its findings and recommendations to the project owners, stakeholders, and others.

  10. Benefits of Using 3-D Visualization The 3-D model can help to maximize the effective time of the RSA team members.

  11. RSA Case Studies • Available June 2013 • Documents Benefits • Details of 3-D PDFs
