The intersection traffic volume is often presented in the form of traffic volume map in the transportation planning. Most of the maps of this kind, however, are illustrated manually. With the introduction of GIS, this paper discusses a GIS-based method of the realization of the special map of the intersection traffic volume. The method can automatically pick up (utilize) the traffic volume data from the database and generate the special map. The method improves the efficiency and quality,and it is explicit, quick and accurate.
