Crash data
Traffic Safety maintains a crash database and provides crash data procurement and analysis. The data is gathered from multiple sources of information and assists in the planning of safety programs and projects. It is important that the data is accurate and timely. There are five basic components in the hazard identification process:
- Establish a crash records database and safety objectives
- Review the crash records, identify crash frequencies/rates, compare to safety objectives and identify potential problem locations
- Develop alternative mitigation strategies
- Implement safety projects
- Evaluate the effectiveness of safety projects through a before/after or other appropriate study.
