The Role of Accessibility and Connectivity in Mode Choice. A Structural Equation Modeling Approach

Abstract

AbstractThis study addresses the effect that characteristics of the Public Transport (PT) network layout and service provision have on mode choice, mainly focusing on accessibility and connectivity. Using data from a mobility survey conducted in Lisbon, Portugal we model the binary choice between PT and private car through a structural equation model. The results indicate a duality in the choice process; good accessibility of the system as a whole encourages PT use but poor connectivity on a particular trip might deter it. A convergence of good performance both in overall accessibility and trip specific connectivity seems necessary for an individual to choose PT over private car
