Class SimpleStreetSplitter

java.lang.Object

org.opentripplanner.graph_builder.linking.SimpleStreetSplitter

public class SimpleStreetSplitter
extends Object

This class links transit stops to streets by splitting the streets (unless the stop is extremely close to the street intersection). It is intended to eventually completely replace the existing stop linking code, which had been through so many revisions and adaptations to different street and turn representations that it was very glitchy. This new code is also intended to be deterministic in linking to streets, independent of the order in which the JVM decides to iterate over Maps and even in the presence of points that are exactly halfway between multiple candidate linking points. It would be wise to keep this new incarnation of the linking code relatively simple, considering what happened before. See discussion in pull request #1922, follow up issue #1934, and the original issue calling for replacement of the stop linker, #1305.
