Concluding
• Further steps – Explanations in better exposure measures (data!) – Further in-depth explanations (risks SPIs)
• Benchmarking road safety – Grouping of homogeneous areas – Basic similarities: structure and culture layer – Tune to relevant characteristics & local views – Normalize for exposure differences in risk? policy making?
