Road Safety Data

ARSC conference 2017

Over the past ten years, crash prediction models (CPMs) have become the fundamental tools of quantitative road safety management. However, there is a gap between state-of-the-art and state-of-the-practice, with the practical applications lagging behind scientific progress. This motivated the review of international experience with CPMs from the practitioner perspective. The main conclusions suggest the need to promote awareness of CPM benefits to road safety strategy and evaluation, policy and programs development, and in guidance development. The paper presents ways to better communicate choice of modelling techniques, CPM results and their practical applications, such as easy-to-use practitioner tools or mapping visualisations.
