Results of the SUNflower work stress the necessity of continuing work in this field with the demonstrated successful approach. Quoting from the general conclusions and recommendations for further European studies, it was found that:

• There is room for further improvement in well-established safety fields in all three countries, and scope to learn from each other to ensure collective experience is used effectively
• Other countries may wish to develop similar analyses in relation to their own national safety problems and policies. The risk indicators for the SUN countries can be used as comparators against which to benchmark their performance in different aspects of road safety, taking into account the characteristics of the different national problems.
• There is a need to organise and support projects on road safety comparison between the SUN and other EU countries in order to understand the problems in each country and enable them to choose the best measures to improve road safety.
• There is a need to investigate and understand the differences in national accident reporting, methodology for collecting exposure data, and the development of performance indicators to compare between countries, in order to confirm the robustness of the methodology proposed.
