Definition SPIs

Safety performance indicators (SPIs) are measures (indicators), reflecting those operational conditions of the road traffic system, which influence the system’s safety performance. Basic features of SPIs are their ability to measure unsafe operational conditions of the road traffic system and their independence from specific safety interventions. SPIs are aimed to serve as assisting tools in assessing the current safety conditions of a road traffic system, monitoring the progress, measuring impacts of various safety interventions, making comparisons, and for other purposes.

Seven problem areas in road safety were selected for the development of SPIs in Europe, they are:

1. Alcohol and Drugs

2. Speed

3. Protective Systems

4. Daytime Running Light

5. Vehicles

6. Roads

7. Trauma Management
