Public transport, Just Noticeable Difference, Passengers, Transfer, Perception


Urban cities are struggling with congested networks, noise and air pollution. Government agencies respond by investing in infrastructures to create integrated public transport systems. Transfers are a key element for the success of network integration. This study explores commuters’ perception of transfers by adopting Weber’s Law “Just Noticeable Difference”. Two trip attributes, travel time and cost, are investigated. Two stated-preference surveys are conducted at the University of Auckland, New Zealand. Results show that, on average, users’ desire at least a 33% reduction in their current travel time and at least a 16% reduction in their current travel cost given basic comfort amenities at the interchange. For an interchange with more comfort, on average, users’ desire at least a 25% reduction in their current travel time and at least a 10% reduction in their current travel cost. The findings are expected to be used as a guideline by planners when developing integrated public transport networks. Recommendations have been made to the Auckland Regional Public Transport Plan.
