Abstract: With the fast expanding of cities, people spend more time on travelling among complex built-up areas such as large subway station. When the emergency event appears, people need a routing method that provides the optimised path fast and a path-finding solution that utilises spatial topological relationship to finish the inner building routing is sounding for this task. The introduced 3D spatial routing solution divides a specific routing problem into several minor routing problems across the related spatial regions to acquire optimised performance. The experiment shows that the spatial relationship introduced into solution increases the speed of the whole route generation significantly, and still maintains a high quality of the path-finding results. In conclusion, the proposed solution has represented a new meaningful approach to apply spatial topological relationship into emergency path-finding solutions for subway areas.
