Pre-compute walking transfers between transit stops via the street network, up to a given distance limit. TODO optimization: combine TransferFinder with stop-to-vertex distance table builder.

Constructor Detail

TransferFinder

public TransferFinder(TransportNetwork network)

Eventually this should choose whether to search via the street network or straight line distance based on the presence of OSM street data (whether the street layer is null). However the street layer will always be present, at least to contain transit stop vertices, so the choice cannot be made based only on the absence of a streetLayer.

Method Detail

findParkRideTransfer

public void findParkRideTransfer()

findTransfers

public void findTransfers()

For each stop, store all transfers out of that stop as packed pairs of (toStopIndex, distance). When applying scenarios, we want to find transfers for only the newly added stops, keeping the existing transfers. However, existing transfer lists will be extended if new stops are reachable from existing stops.
