Research summary

My research includes transport policy analysis, accessibility, travel behaviour, public transport, planning, reducing car use, social exclusion and travel by various groups in the community. My earlier work involved the development of computer models of the relationships between transport and urban areas.

Travel by people with non-visible disabilities

I am studying ways of addressing the barriers to travel for people with non-visible disabilities, particularly mental impairments. I have reviewed the literature on the barriers to travel and the ways that they have been addressed. I carried out an online survey of travel by people with mental health conditions, such as anxiety and depression. This showed that the main barriers to travel for people with these conditions were concerns about the behaviour of other travellers, lack of confidence that they would receive support when required and wayfinding. More women than men were affected by these anxieties. Ways in which their concerns about travel could be addressed were identified.

Accessibility and social exclusion 

I led work on ways of reducing social exclusion by developing methods to facilitate access for older people and children as part of the research programme AUNT-SUE (Accessibility and User Needs in Transport in Sustainable Urban Environments). More recently I have been involved in examining the impact of concessionary bus fares for older people and the barriers to travel for older people. With colleagues I was involved in a project to examine ways of using transport to reduce the impacts of poverty. 

Children's travel behaviour, play and independent mobility 

I led an EPSRC-funded project on the health and car dependency implications of children's car use. This involved questionnaire surveys, monitoring of children's physical activity over a period of four days using portable accelerometers in parallel with the completion of activity and travel diaries, and evaluation of walking buses. This was followed by the CAPABLE project (Children's Activities, Perceptions And Behaviour in the Local Environment) to investigate the relationships between children and the local environment. This involved fitting children with GPS monitors as well as the accelerometers. I was involved in a collaborative project entitled ‘Physical activity and car dependency in modern childhood’ which involved researchers from Norway, Denmark and Finland. I was also involved in a project investigating children's independent mobility co-ordinated by the Policy Studies Institute. I was an advisor on the project ‘Neighbourhoods for active kids’, in Auckland, New Zealand.

Encouraging a shift from the car to walking and cycling 

I carried out a contract for the Department for Transport on the potential for reducing the number of short trips by car, which involved survey work and detailed analysis of the factors which underlie the reasons why people use their cars for many short trips. I have examined the barriers that need to be overcome to reduce car use and the increase the amounts of walking, cycling and local bus use. I have led a project funding by the Department for Transport to identify the evidence that transport can provide everyday physical activity, and to identify the research that needs to be conducted by working with a group of experts on physical activity and the environment. More recently I was involved in a project to examine the impact of the Cambridgeshire Guided Busway on walking and cycling, with colleagues from the MRC Epidemiology Unit in Cambridge and the University of East Anglia.

Teaching summary

Since I became Emeritus Professor in October 2011 I no longer teach. Previously most my teaching was on the MSc programmes in transport taught jointly with Imperial College. I taught course units on ‘Travel demand and its modelling’, ‘Transport policy’, ‘Transport and its context’, ‘Quantitative methods’, and ‘Public transport’.
