This index measures the strength of each activity node for integration of multi-modal public transport services, and by extension, the flexibility of users to move around the city on public transport. It captures the suitability of activity nodes for making transfers or breaks of journey with minimal disruption to the flow of movement.
The nodal connectivity index expresses the attractiveness of a place for land use development that depends on good access by public transport, and can also be seen as a proxy for the confidence that can reasonably be exerted by urbanites to build their activities around public transport use, or by businesses around public transport access.
Nodal connectivity
where:
Vi = Connectivity index for node i
aij = links converging in node i, with jÎN(i) and i≠j
N(i) = network nodes adjacent (nearest neighbours) to node i
fr(i) = number of rail departures per hour per direction from node i
ft(i) = number of tram/LRT departures per hour per direction from node i
fb(i) = number of bus departures per hour per direction from node i
ff(i) = number of ferry departures per hour per direction from node i
or = average network-wide load factor rail (passenger-km divided by revenue train-km)
ot = average network-wide load factor tram/LRT (passenger-km divided by revenue train/vehicle-km)
ob = average network-wide load factor bus (passenger-km divided by revenue vehicle-km)
of = average network-wide load factor ferry (passenger-km divided by revenue vehicle-km)
