Assessing the Physical Environment Related to Cycling and Walking

Until about 15 years ago, researchers were mainly interested in individual and psycho-social determinants (for example age, sex, socio-economic status, self-efficacy, attitudes) of cycling and walking behaviours (Sallis et al. 2006). However, interventions focusing on psycho-social determinants only resulted in small increases in physical activities (PA), which were mostly not maintained in the long term. Furthermore, these interventions only reached a limited number of people.
