The important objective of the RiPCORD-iSEREST project is to stimulate a safety oriented management of (secondary) road infrastructure. In order to achieve this, a practical management tool has been developed to assist road managers and other decision makers on a regional level in finding the most appropriate way road safety intervention measures can be made. This practical management tool is called 'Decision Support Safety Tool (DST)'. This management tool is based on the VIB that was developed in 2003 and successfully applied in 7 regions in the Netherlands by Mobycon. The basis for the VIB was the Road Safety Explorer by the SWOV in the Netherlands. The DST is based on the relation between road safety (the amount of deaths and hospital injured or accidents) and the amount of AADT (cunent situation and expected increase). This is called the risk: the amount of deaths and hospital injured (or accidents) per amount of traffic (AADT). The SWOV has described this as "the level of road safety is the product of the mobility of the road user and the risk of taking part in this mobility". The DST predicts the number of deaths and hospital injured in a forecast year based on: The actual road, traffic and accident situation in a basis year; The expected increase of the AADT; The risk reductions by implementing road safety measures. Within this project the DST has been tailor made for local circumstances in different ECcountries. The most important modifications to the DST are modifications with regard to the user-interface of the DST and the road safety measures (implementing own road safety measures by each country, the possibility to get more information about the measures, translation from English to another language, etc.) within the DST. The information about road measures (costs and effects) is extracted from SEROES (Expert System; WP9 in the RiPCORD-iSEREST-project). The costs and effects can of course differ per country, but when there is no information available in a country, this information can be used as a starting point. The overview of measures in the DST should be checked before working with the DST is a country by a team of experts from this country in order to create a sufficient and appropriate list of (potential) measures. Implementing new measures or adapting specific costs or effects can be done easily. The only restriction is that there should be information available about the estimated costs and effects. The DST, together with SEROES, has been demonstrated in three regions in Europe: a region in Turkey, Poland and The Netherlands. More information about these demonstrations and the evaluation of these demonstrations can be found in the fmal deliverable of WP 12 of the RiPCORD-iSEREST-project. The final conclusion of this evaluation is that it is possible to work with the DST in different EC-countries despites a lack of digital data available. It is only strongly recommended to let the process be managed by an experienced institution or consulting company. (Author/publisher)
