Transportation and. Accessibility Law came into operation in Japan May 2000, which regulated barrier-free technical standard for ships as well as other transportation facilities. It is expected that more and more wheelchair users will make use of sea voyage because of the increase of barrier-free ships. But the influence of mixture of foot pedestrians and wheelchair users on evacuation safety has not yet been studied well and its investigation is a pressing need. This paper describes walk model of foot pedestrian group who is not into a panic and overtakes a wheelchair on passage. The model is designed based on the experiment that simulates evacuation of foot pedestrian group and a wheelchair user on straight passageway of ship. A Simulation program is developed faithfully based on the walking human model and the validity of the model is investigated by comparison of experimental results and simulated one. This model is expected to be a base case for more complicated and more influential environment on evacuation safety on ships, like stairs, doors and differences. Many conventional walking human models in escape analysis are designed by using physical phenomenon, such as potential energy and electromagnetic field, and so on. This model uses simple cognitive cycle which includes prediction and modification, and uses simple behavior rules according to a distance to a wheelchair. Despite of its simplicity and ease of description it realizes group action and it shows satisfactory performance.
