Abstract
For the transfer planning in a freight terminal, passage width is one of the main factors. Although three passage widths are important for transferring by a truck, there are very few reports about right-angled passage width. So the experiment is carried out mainly on the right-angled passage width by using a forklift-truck and a hand-truck. The summary of the results is shown below. 1. It is possible to arrange the experiment data of "delay time" by the intersection area without regard to inlet or outlet passage width. Here, "delay time" is defined as the difference time between the time to pass right-angled corner and the time to go straight the same distance on the same width passage. 2. It becomes possible to estimate the delay time from the truck velocity on straight passage and the product of the length and breadth of a truck.
