In this paper, we propose a map matching algorithm for a map information sharing system used by refugees in disaster areas. The map information sharing system stores the roads passed by a refugee as map information. When another refugee comes close to the refugee, they exchange their map information each other in ad-hoc network manner. Our map matching algorithm is based on geometric curve-to-curve matching approach and provides road segments on which a refugeemoves, from position data by GPS. In order to decrease matching errors, our algorithm adopts the point-to-curvematching method as initial matching, and incremental matching for suppressing error propagation. Experimental results shows that our proposed algorithm achieve the best result in comparison with the conventional point-to-curve and curve-to-curve map matching methods.
