This study aimed to broaden Theory of Planned Behaviour (TPB) by including healthy urban performance attributes of
the residential neighbourhoods as an additional predictor for walking behaviour. First, the study reviewed the literature
on TPB and walkability in residential environments, and then constructed a TPB model based on walkability to set the
hypotheses. The study explored the correlations among walkability attributes and walkability behaviour through a survey
conducted with residents in Ankara, Turkey (n= 220). To analyse the data, first confirmatory factor analysis and
later, structural equation modelling were used. The findings of the study highlighted two aspects of planning for a walkable
neighbourhood: (i) a walkability model based on the three constructs of TPB should not neglect the measured
and experienced urban performance; (ii) utilizing pedestrian environment for walking as fully as possible requires a
collaborative and an experiential approach as well as a multi-parameter decision-making process.
