The document discusses the 2DECIDE project, which aims to create a decision support toolkit for investment decisions in intelligent transport systems (ITS) applications and services in Europe. The toolkit will provide best practices, cost/benefit information, and evaluation reports on ITS projects. It will merge knowledge from the US Department of Transportation's existing ITS toolkit and the new European toolkit to improve decision making on ITS deployment. Potential opportunities of merging the two toolkits include knowledge sharing and quality enhancement, while threats include the risk of the US toolkit dominating or not being fully represented in the European format.
