  1. Best practice features in crash data systems – some examples Blair Turner, Principal Research Scientist, Australian Road Research Board

  2. Background • Research project funded in Australia by Austroads (www.austroads.com.au) • Aim to identify good features from crash data systems • Focus on analysis tools • Literature review, surveys, demonstrations - 20 data systems

  3. Areas of interest • Data entry • Types of data collected • Analysis of crashes – sites of interest • Analysis of crashes – policy level • Mapping • Integration with other data • Quality control issues • Monitoring sites of interest • Dissemination of data

  4. www.austroads.com.au

  5. Mapping

  6. Map of crash locations

  7. Map of crash locations – by severity

  8. Map of crash locations – by severity

  9. Speed crashes by time of day

  10. Alcohol crashes by time of day

  11. Identifying trends

  12. Cross tabulation

  13. Analysis tools

  14. Site summary

  15. Site summary

  16. Selecting and treating sites of interest

  17. Analysis tools – sites of interest

  18. Factor matrix

  19. Collision diagram

  20. Analysis tools – crash diagram

  21. Exporting data and integration with other data sources

  22. Combining crash data with other data sources

  23. Exporting data for other applications

  24. Exporting data for reporting

  25. Concluding comments • It costs a lot to collect crash data • A small additional investment can produce some tools that will save a lot of time and money in the future • Mapping is a key feature – ensure data can be exported to a GIS system if this is not already built in to the database system • Many other tools available, but check with the end user to see what is of greatest value • Check the Austroads report for what others are doing.
