Although digital spatial statistics and map are becoming available recently, it is insufficient to study the configuration methods of data and parameter for a traffic assignment. In this paper, configuration methods are studied for traffic assignment using a GIS data. In detail, a method constructing road network from digital map and a set up method of a link parameter are studied. Moreover, methods speeding up assignment calculation in term of data configuration are explained. In numerical simulation, the methods are evaluated by assigning traffic in Tokyo metropolitan area and the results are shown in calculation time suitable for practical use and in assignment accuracy.
