This 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.
