org.opentripplanner.graph_builder.linking.SampleStopLinker

public class SampleStopLinker
extends Object

Link transit stops to the street network in a non-destructive manner; i.e. don't modify the street network. Being non-destructive is important in Analyst; new transit models should not affect the length of existing streets, even slightly (due to float roundoff from splits, etc.) An error of even a few seconds can be significant if it causes the router to miss a transit vehicle or transfer, or causes the stop to move just beyond a hard boundary. We do this by using the same linking code that is used for Analyst (the SampleFactory code) which additionally means that this code path is used and tested in multiple applications. This is not currently used. But it could be very useful for patching temporary transit lines in interactively generated scenarios.

Method Detail

link

public void link(boolean makeTransfers)

Link all transit stops. If makeTransfers is true, create direct transfer edges between stops linked to the same pair of vertices. This is important e.g. for transit centers where there are many stops on the same street segment; we don't want to force the user to walk to the end of the street and back. If you're not generating transfers via the street network there is no need to make transfers at this stage. But if you're not generating transfers via the street network, why are you using this module at all?
