The role of contestable processes in advancing sustainability in transport and planning

Abstract

Sustainable transport requires not only solid evidence to support policy and practice, but also to allow this to be examined with a high degree of transparency. Not all technical reports have the supporting evidence (or indeed models) made readily available, and even fewer provide enough material and methods to allow others to reproduce or evaluate the methods used as well as the results reported, or to assess alternatives not covered in the report. Control over such issues is a matter of governance. Governance issues are important in advancing sustainable transport, as organisations in both the physical planning and transport fields have longer policy development and implementation horizons..
