CHARACTERSITICS OF BUS PASSENGER INTERCHANGE
To the best of my knowledge, this research represents the first comprehensive attempt
to combine bus and Underground journey stage data derived from smart card fare payment
transactions into complete journeys using informed elapsed time assumptions to identify
interchanges. The availability of complete journey information, albeit approximate, would be
an advance in knowledge for network planners in evaluating the costs and benefits of changes
to the bus network. Thus, the goal of this chapter is to develop ranges of elapsed time
thresholds that could be used to link bus and Underground journey stages into complete
journeys using smart card data.
