Class TransitNodeRoutingPrecomputation.AccessVertex<V,​E>

  • Type Parameters:
    V - graph vertex type
    E - graph edge type
    Enclosing class:
    TransitNodeRoutingPrecomputation<V,​E>
    public static class TransitNodeRoutingPrecomputation.AccessVertex<V,​E>
extends java.lang.Object
    Forward or backward access vertex computed for a certain vertex $v$ in the graph.

    In the transit node routing if $u$ is a forward access vertex for $v$, it means that if you want go far away from $v$, it is highly likely that you would need to pass through $u$. Correspondingly, if $u$ is a backward access vertex for $v$, it means that if you want to go to $v$ from far away, you would highly likely go through $u$.

    Stores transit vertex and the shortest path between $v$ and vertex. If this is a forward access vertex, then vertex is the ending vertex in the path, Otherwise it is a starting vertex of the path.
