1. By Srinivas S. Pulugurtha, Ph.D., P.E. Assistant Professor of Civil Engineering University of North Carolina, Charlotte Presentation at TRB ABJ60 Workshop on Spatial Data Needs and Opportunities Focus Area: Safety

2. VISION STATEMENT What we would like to see in the future … MISSION STATEMENT Research and promote application of spatial data and information science technologies to improve safety on transportation systems by …

3. GIS-science/ visualization techniques

4. Highway Safety Information Systems IDOT Crash Analysis Tool

5. Truck Routes Infrastructure Ped/Bike

6. Automatic Crash Data and Location Collection

7. Crash Scene Reconstruction 3-D Laser Scanning

8. SAFETY APPLICATIONS/NEEDS Data quality/consistency/currency Existing tools and data that are underutilized Integrate data from many systems Collecting the “right” data Data availability on all systems All states will have effective safety GIS in place – incentives?

9. SAFETY APPLICATIONS/NEEDS (Cont.) Implications of section 1401 on states – –Requires all states to identify and publish the top 5% of high crash locations on all public roads – –Existence of crash data tied to local geometry? – –Local road attributes required to do a good ranking/rating of the worst 5%?

10. SAFETY APPLICATIONS/NEEDS (CONT.) Hazmat route registry/national standard Real time tracking of vehicles for emergency response/cell phone/”incursion zones” Evacuation/climate change Latent travel demand and traffic shift effects on safety Rail crossing data consistency

11. GRAND VISION Grand Vision – quality geodata to support safety analysesGrand Vision – quality geodata to support safety analyses –Turning movement counts –Highway geometry – vertical and horizontal –Intersection characteristics – turn lanes, bays, signal timing –Exposure by driver and vehicle type, pedestrian and bike flows –Routable intermodal network flows –Vehicle reported crash data, real time (black box report via cell phone)
