Method HasValidEdge

include/engine/geospatial_query.hpp:556–585

* Checks to see if the edge weights are valid. We might have an edge, * but a traffic update might set the speed to 0 (weight == INVALID_SEGMENT_WEIGHT). * which means that this edge is not currently traversable. If this is the case, * then we shouldn't snap to this edge. */

     * then we shouldn't snap to this edge.
