Percentages represent column percentages. Data collected in 2009 in Cambridge, UK. p values represent differences between ‘car only’ and ‘car in combination with walking or cycling’ groups.
The seven items comprising the perceptions of the route environment were: ‘It is pleasant to walk’, ‘There is convenient public transport’, ‘There is little traffic’, ‘There are no convenient routes for walking’, ‘It is safe to cross the road’,’ The roads are dangerous for cyclists’ and ‘There are convenient routes for cycling’.
