Network-Wide Road Safety Assessment in Czechia

Year: 2026

Type: conference-paper

Abstract: The Network-wide Road Safety Assessment (NWA) is a novel tool under the Directive (EU) 2019/1936 on road infrastructure safety management, which combines proactive assessment (in-built safety) and reactive assessment (crash-based safety). In 2023, the European NWA handbook was published for member states to adapt to their national conditions and apply in assessing their main road networks in 2024. The paper presents the guidelines, developed by CDV – Transport Research Centre and describing possible approaches in the Czech conditions. Firstly, it describes the approach based on the European handbook, which was used to implement the NWA of Czech motorways and national roads in 2024. Secondly, it describes three alternative approaches, which provide some simplifications (e.g., reduced data collection requirements) and additional functionalities, such as the availability of a ranked list of results. The presented guidelines are applicable in future assessments (either based on the European handbook or using the alternative approaches) in Czechia, as well as other member states.
