Road safety has become quite a discussed issue in the Czech Republic in the end of the nineties. Insufficient development of the road safety indicators starting in 1986 with the top in 1992 led to a number of different road safety activities especially at the local level such as different traffic calming measures, especially roundabouts, humps, different types of more safer pedestrian crossing and new approach to the stops of public transport. New approach to research in this area is made in the project BESIDIDO made by the team of national experts co-ordinated by Centrum dopravniho vyzkumu (Transport research centre). Based on the state of art in selected EU countries, new analysis of the selected court expert reports, data from the Brno Trauma Centre and deep analysis of about 160 selected traffic calming measures the new guidelines has to set for further improvement of road traffic safety in the Czech Republic. Some best practices, collect in this project, may be surely used also for safety improvement also in some others EU countries. Project would be inspirational above all for a new EU country from Central and Eastern Europe
