Large parts of the Danube road network rate poorly for safety, particularly for vulnerable road-users, and death rates in many countries are higher than the EU average. Many countries lack professional capacity and aproaches to the problem vary. RADAR (Risk Assessment on Danube Area Roads) implements learning and transnational cooperation activities at different levels to help the responsible road safety organisations in the Danube area identify risk on their road networks and helps them reduce risk systematically, by improving infrastructure and road layout. RADAR addresses all road-users but pays particular attention to (TA2) vulnerable road users and safety on major roads near schools (TA4). It also approaches the issue of safety in a holistic way (TA1) and tackles speed (TA3) as a major risk on roads. The project contributes to Specific Objective 3.1 of the DTP Programme, in line with the restricted topic on transport safety as outlined in the 2nd Call for Proposals. The project includes work in 11 Danube countries, has 10 PPs, joined by 11 ASPs (mainly ministries or road authorities) in most countries as well as the EUSDR PA1B and SEETO. Training courses and study visits for professionals of road safety organisations guide participants PPs through the steps from analysing safety on their road network to defining road safety solutions that are cost effective and lead to the highest reduction of crashes and casualties. The establishment of a transnational Road Safety Expert Group increases knowledge across the region and draws on input from beyond its borders towards a first region-wide “Danube Infrastructure Road Safety Improvement Strategy” and national Action Plans defining clear steps for implementation of its goals. Finally, Pilot Actions (8) show authorities steps to be taken to prioritise road sections. Implementation-ready Road Layout Concept Plans show what needs to be done at selected locations prior to crash countermeasure implementation.
