InDeV - In-Depth understanding of accident causation for Vulnerable road users

  1. 1. www.indev-project.eu 1st European Conference Results from road transport Research in H2020 projects Tom Brijs, Hasselt University
  2. 2. • develop an integrated methodology to study VRU accidents and • improve assessment of VRU-accident costs InDeV goals: www.indev-project.eu
  3. 3. • Accident databases (police & medical care) • In-depths accident investigations • Traffic conflicts/observational studies • Naturalistic cycling/walking (mobile app) • Self-reported accidents www.indev-project.eu “Integrated methodology” utilises:
  4. 4. • Accident databases (police & medical care) • In-depths accident investigations • Traffic conflicts/observational studies • Naturalistic cycling/walking (mobile app) • Self-reported accidents www.indev-project.eu “Integrated methodology” utilises: most development happens here
  5. 5. Traffic conflicts www.indev-project.eu Undisturbed passages Slight injury Severe injury Fatal Accidents Serious conflicts Slight conflicts Potential conflicts Damage only
  6. 6. Traffic conflicts www.indev-project.eu Undisturbed passages Slight injury Severe injury Fatal Accidents Serious conflicts Slight conflicts Potential conflicts Damage only just one step below accidents -> very similar
  7. 7. Video processing software: • Watch-dog • Semi-automated processing • Fully automated processing Mobile app Technical tools www.indev-project.eu
  8. 8. www.indev-project.eu
  9. 9. www.indev-project.eu
  10. 10. www.indev-project.eu
  11. 11. Main challenge – stable performance over LONG period www.indev-project.eu
  12. 12. www.indev-project.eu
  13. 13. Whachdog -> manual check -> -> trajectory production -> -> test of indicators –> -> validation towards accident data Workflow (in progress) www.indev-project.eu
  14. 14. • Current status of accident cost calculations in the European countries: – General structure of valuation methods: • complies with recommendations of former EU projects (Component structure, valuation methods), e.g. COST 313, HEATCO, UNITE – Definitions of ‘fatality’ and ‘injured victim’ • ‘Fatality’ is defined consistently in all EU countries • ‘Seriously injured’ has very different definitions – Components and the included items • Different combinations in every country (see next slide) – Underreporting • Is considered in very few countries Accident cost calculation in EU countries and its adaptation concerning VRU safety www.indev-project.eu
  15. 15. • Inclusion of the additional injury category ‘MAIS 3+’ • Average unit costs per casualty – Include medical costs, production loss and human costs – Not included: property damage and administrative costs • Dealing with Underreporting Accident cost calculation in EU countries and its adaptation concerning VRU safety www.indev-project.eu Next Deliverable: Development of calculation options with an emphasis on VRU Injury: slight < serious < ‘MAIS3+‘ < fatal
  16. 16. • What type validation is best/feasible? • What conflict indicators are most valid? • Performance improvement of technical tools • Accident cost calculation: What are the options to adapt it to VRU? • Handbook of safety analysis for vulnerable road users Remaining work
