Emeritus Professor of Transport Studies, Department of Civil, Environmental and Geomatic Engineering

The focus of Roger's research is transport policy analysis. He is interested in ways of overcoming the barriers to reducing car use and improving health through increasing walking and cycling. He has researched into the influence of car use on children’s physical activity and their use of the local environment using accelerometers and GPS monitors and is also involved in a project to examine the implications of children’s independent mobility in countries around the world. He was also involved in a project to examine the health impacts of the Cambridgeshire Guided Busway with colleagues in the MRC Epidemiology Unit in Cambridge and at the University of East Anglia and led the development of the software tool AMELIA (A Methodology for Enhancing Life by Increasing Accessibility) to help make transport policies more socially inclusive.
