The map shows several roads (A1,A3,A4) with junctions. Straight bars are shown along or parallel to stretches of road between the junctions. Each bar may correspond to the number of reports (Mj 1-3) of vehicles passing a given point on each road. Route arrows with time measurements (tau12,23,31 j) are provided at the junctions. Time values are calculated according to given mathematical formulae.
