Description

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.

Agenda

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

  1. VDOT Crash Tool Filters and Data, Map, Node Info… Much More!
  2. Using Excel to find the highest-crash intersection
  3. Advanced Excel to rank the top intersections – County Level Case Study
  4. Revisit the Crash Tool for Average Annual Daily Trip (AADT) Data and Merge with the Details of the Crashes in your locality or area of interest
  5. Case Study – Compute Crash Reduction Value of Reconstruction of an At Grade Signalized Intersection to be a Grade Separated Interchange

Module 3: Calculating Crash Reduction Benefits

  1. Calculating Net Present Value (NPV) of Crash Benefits
  2. Case Study – I-95 Interchanges – Thornburg / Mudd Tavern & Rt 3 (Plank Road) City of Fredericksburg, VA
  3. Intersection Ranking Using AADT and Crash Data
  4. VDOT’s PSI Map – Case Study Locations
  5. VDOT’s PSI Map and VDOT’s Crash Tool – Local government & PDC / MPO / TPO Safety Analysis Using Both Valuable Tools
  6. Case Study – Converting High Crash Locations and Crash Attributes into Google Maps
  7. Calculating Predicted Crashes Using VDOT’s Safety Performance Functions (SPF’s)
  8. Google Maps to Isolate Different Crash Types for Countermeasure Selection

Module 4: Case Study – Combating Runoff Road Crashes at the County, PDC / MPO / TPO levels

  1. VDOT’s Crash Tool Filter – Road Departure (RD) Crashes
  2. FHWA Every Day Counts – Crash Type
  3. Peak Searching & Sliding Window Methods
  4. Crashes’ Attributes Imported to Google Maps for Street View Review of High Scoring Locations
  5. Countermeasures Selected Based on Screening Each Location
  6. Crash-Based Network Screening
