1. Data LHRa. Mobil penumpang = 2002 kend/harib. Mobil Pick up (6 ton) = 46 kend/haric. Bus sedang (6 t0n) = 44 kend/harid. Bus besar (9ton) = 57 kend/harie. Truck sedang (13 ton) = 74 kend/harif. Truck 2 As (18 ton) = 96 kend/harig. Truck 3 As (25 ton) = 119 kend/harih. Trailler (40 ton) = 58 kend/hari
