Cycle or Not: Usage of Modified Theory of Planned Behaviour to understand the cycling decision among cyclists and non-cyclists

Abstract

Theory of Planned Behavior (TPB) and its modified versions have frequently been used to understand the determinants of planned behaviour.  This research utilized the Modified Theory of Planned Behavior (MTPB) to understand the factors that affect the decision to cycle among cyclists and non-cyclists in Sri Lanka.  Using an island-wide questionnaire survey, data related to intention to adopt cycling and four main constructs of TPB namely, individuals’ attitudes, perceived behavioral control (PBC), subjective norm (SN) and perception of the environment (EP) were collected. Structural Equation Modelling (SEM) analysis was used to develop MTPB models. For both cyclists and non-cyclists, PBC showed a strong positive effect on the decision to cycle while EP also had an effect. SN did not have a significant influence on the cyclists’ and non-cyclists’ intentions to cycle.  The safety of the cyclists was a key concern for all participants. The study emphasized that the ability to cycle and having a positive perception can lead to more cycling. The presence of proper cycling infrastructure itself may not promote cycling. Motivations through, family and social support may also be effective. A set of interventions focusing on the safety of the cyclist, cycling education, and infrastructure improvements that can inform policymakers and transport professionals are proposed based on the above outcomes.
