This workshop allows localities, Planning District Commission (PDC), Metropolitan Planning Organization (MPO) or Transportation Planning Organization (TPO) staff the ability to use VDOT’s Potential for Safety Improvement (PSI) Map and VDOT’s Crash Tool to find higher than expected crash locations for project planning and ranking purposes. Both roadway segments, intersections and interchange movements and conversions are part of the presentation and classroom exercises. Tips for converting crash data set attributes into Google maps will allow network screening and countermeasure selection. Methods for computing crash reduction benefits and Net Present Value (NPV) for candidate sites are also included. Delivered in four (4) modules with hands on exercises and group discussions throughout the day, as well as the presentation workbook, leaves attendees with the tools to select projects for their Transportation Improvement Programs and local Capital Improvement Project 5-year plans using crash data and the Safety Analysis Process.


Module 1: Crash Data – Virginia’s Localities and PDC / MPO Needs

  1. Crash Data – Where Do I Start?
  2. VDOT’s Crash Tool – Downloading Data for your locality, Planning District (PDC), Metropolitan Planning Organization (MPO) or Transportation Planning Organization (TPO)
  3. VDOT’s Potential for Safety Improvement (PSI) Map / Network Screening

Module 2: Putting it All Together: Crashes Downloaded from the Crash Tool in Excel; VDOT PSI & VDOT Pedestrian Safety Action Plan (PSAP) Maps in ArcGIS
