Understanding Added Value in Integrated Transport Planning

Transport infrastructure projects have become more integrated in nature. An important driver of the ambition to approach space in a more integrated manner is the idea that doing so will generate added value. However, in transport infrastructure planning practice, the argument to adopt integrated planning approaches seems to be mainly rhetorical in nature. The aim of this paper is to contribute to the discussion about the notion of added value through integrated planning by developing an analytical evaluation framework. In order to do so, we go back to one of the founding fathers of decision-making sciences and present a conceptual synthesis. We explore this synthesis by conducting a literature review and an illustrative expert session. We conclude with the analytical evaluation framework and elaborate on implications in practice.
