Paul is an Honorary Associate Professor of Geography in the School of Science at UNSW Canberra, Australia, where his research focuses on two critical and related issues for modern cities: children’s well-being and the dominance of speed and mobility in urban planning and society. His research demonstrates that child-friendly modes (walking, cycling and public transport) are also the modes that (paradoxically) reduce time pressure for urban residents. He co-authored Children and Their Urban Environment: Changing Worlds (Routledge, 2011), and co-edited Risk, Protection, Provision and Policy, Volume 12 in Geographies of Children and Young People (Springer, 2017). Rodney Tolley has researched and written in the field of active, sustainable transport for over 40 years. He was Reader in Geography at Staffordshire University in the UK until 2004, and is now the Conference Director of Walk21, a global partnership of walking researchers and practitioners. He is the Founding Director of Rodney Tolley Walks and is an experienced international speaker and consultant. He makes time to walk every day.
