Table 3: Truck transport time of empty and loaded trucks from loading area to dumping area. Figure 8 shows the results of analyzing the average speed of trucks by section. It was found that the average truck speed was greatly influenced by the location and characteristics of the section during both empty and loaded operation. The truck speed tended to be higher if the section approximated a straight line, with good driver visibility. In the case of empty operation, the average speed of the truck was found to be high in beacon IDs 1-2, 2-3, 5-6, 10-11, and 11-14. In the case of loaded operation, the truck speed was high in the beacon IDs 10-12 and 1-20, which is believed to be because it was easy to secure visibility as the truck came out from the tunnel. Moreover, it was confirmed that the speeds were higher in the section (beacon IDs 13-12, 16-15) without a loading or dumping area around the route.
