Introducing elements of due diligence in sustainable urban freight transport planning

This paper presents the findings from a Delphi study that has investigated the feasibility of local authorities adopting an updated transport planning process that incorporates the concept of due diligence. The Delphi panel consisted of twenty experts representing local authorities, academia and other relevant freight stakeholders from Sweden, the United Kingdom (UK), Germany, France and The Netherlands that were engaged via email survey. This resulted in the development of a refined theoretical framework that enables freight to be fully considered in local authority transport planning. (C) 2016 The Authors. Published by Elsevier B.V.
