摘要：Path finding requirement for people under restricted situation is difficult to meet. Traditional routing solution such as A* algorithm is not suitable for the restricted area. For routing requirement under three dimensions is much more complex than under two dimensions, the traditional A* algorithm should be improved to meet the routing requirement. The new path finding solution concentrates on the experiment area's composition and each movement's moving style. The test result has shown that the improved A star algorithm is superior to traditional A star algorithm in both storage consuming and time efficiency
