Running on empty argues that past failure to address fundamental inequalities in the ability of low-income households to access adequate transport has undermined effective delivery of welfare policies in the US and UK; describes the new policies and initiatives being developed to address this oversight; outlines the case for including transport as an area of social policy inquiry, identifying key factors and uses case study examples of practical initiatives from both sides of the Atlantic to draw lessons for future policy and practice. The book is aimed at students, researchers, policy makers and practitioners with an interest in understanding the social effects of transport policy. The comparison between US and UK policy and practice adds an important new dimension to those familiar with the subject, while its easy-to-read format and well-illustrated case study examples make it an ideal first text for newcomers to the field.
