Sizing up the City
People move about our cities in many ways. Babies are pushed around in buggies, people with disabilities propel themselves around in electric wheelchairs. People walk or ride bicycles; others catch public transport - buses, trams or trains. Many people rely on carbon-based fuels to power the technology that moves them about: they take their own cars. To support the 'just-in-time' delivery systems, drivers move goods all over our cities many times a day in light vans. Heavy truck drivers take goods to and from the ports and airports.
