"The European Transport Policy (ETP) proposes the concept of co-modality as an essential instrument to achieve, at the same time, a high level of mobility and of environmental protection. But the existing transport system still remains far away from that concept. The interface between long and short-distance transport networks remains as the weak link in the transport chain for both, passengers and freight. This situation favours the choice of uni-modal solutions, and jeopardizes the development of more competitive and sustainable transport chains. The improvement of long/short distance interfaces is a key element to achieve the objectives of the ETP. Approaches to this issue have typically been developed at the project level, on a case-by-case basis. At best, decision-makers benefit from experiences in other regions, but conflicts are rarely considered and solved in advanced, and they are rather addressed as they emerge, so that optimal solutions are rarely adopted. The purpose is to develop innovative tools for the analysis of interfaces, check these tools in a number of case studies, and make recommendations to stakeholders in order to get: -A more systematic approach to the whole project cycle of interfaces. -Concrete guidelines for decision makers in order to cope with the challenges of a particular project, and to get the most from the opportunities that each project offer. -A friendlier regulatory environment; fostering cooperation and supporting better integrated interfaces. -Improved mechanisms for financing those concepts with a higher degree of integration (including EU’s funding schemes). -In-depth involvement of stakeholders, and particularly of transport operators. Research has focused thus far on quite specific aspects of the interface problem. This is one of the reasons why public agencies lack more standardised approaches to new projects, and fail in establishing effective cooperative frameworks."
