Most of Ralph’s research has an international comparative perspective, contrasting transport and land-use policies, transport systems, and travel behavior in Western Europe and North America. Ralph’s research interests include:
(1) the influence of transport policy, land use, and socio-demographics on travel behavior;
(2) active travel and public health; and
(3) public transport demand, supply, regional coordination, and financial efficiency.
