This study investigates determinants of travel behaviour within TOD-based developments in Delhi through an expert-based analytical approach. A structured questionnaire survey was administered to 42 domain experts, including planners, engineers, researchers, and policy professionals. The study employs Partial Least Squares Structural Equation Modelling (PLS-SEM) to examine causal relationships among accessibility, urban density, public transport, government policy, and socio-economic factors. Results indicate that accessibility, urban density, and public transport significantly influence travel behaviour, highlighting the importance of compact development, efficient connectivity, and reliable transit systems. In contrast, government policy and socio-economic factors were not found to have a direct significant effect, suggesting indirect or mediated influences. The findings demonstrate the value of expert-based analysis in capturing systemic and policy-relevant insights for TOD implementation and offer practical guidance for planners and policymakers. https://ceij.ut.ac.ir/article_107064_241c2c0d8f63e5a7a8b455939347fff2.pdf
