Job van Eldijk, Jorge Gil and Lars Marcus has published an article in European Transport Research Review entitled: Disentangling barrier effects of transport infrastructure: synthesising research for the practice of impact assessment. In the article they review the literature on barrier effects of the last 60 years and aim to offer guidance for the use of objective methods of assessment of barrier effects. The first contribution is a conceptual model for the barrier effects of transport infrastructure and their determinants. The second contribution is an overview of tools for the assessment of barrier effects. They conclude that a multi-disciplinary approach is required, supported by the conceptual model and the overview of assessment tools. Investments in transport infrastructure can then be based on broader decision support involving not only the benefits of increasing regional accessibility but also the cost of reducing local accessibility.
