A Heuristic Approach for Exploring Uncertainties in Transport Planning Research

This literature review aims to identify situations of uncertainty from differing perspectives of transport planning research. It elaborates a heuristic framework based on three potential sources of uncertainty: reality, knowledge, and products. The heuristic approach focuses on the way in which uncertainties are first identified as part of the planning context and process, then translated into planning artifacts and concepts, and finally managed in the selection of planning options and effects. We illustrate how this framework can provide a useful tool for theoretical and empirical research in transport planning.
