+// Heuristics:
+// For less pedestrian roads we add fine by setting smaller value of speed, and for more pedestrian roads we
+// set greater values of speed. Algorithm picks roads with greater speed first, preferencing a more pedestrian roads over
+// less pedestrian. As result of such heuristic road is not totally the shortest, but it avoids non pedestrian roads, which were
+// not marked as "foot=no" in OSM.
+// Despite we assume trunks, primary and secondary roads footable with some fine,
+// we assume links trunk_link, primary_link and secondary_link are prohibited.
