As a part of investigation of transportation planning method for saving energy, a numerical model of commuter traffic flow has been developed using population of cities and geographical data. This paper describes a model of traffic flow based on the analogy between population and quantity of electricity. The working field of electric force is formed around a charge. When the population of cities is replaced by the quantity of charge and the direction of the electric force is traced, adequate traffic routes connecting cities with large populations can be obtained. In addition, traffic flow distribution of individual commuting methods was calculated. It was assumed that the traffic flow is decided by attraction force dependent on daytime population of the central city and by influence proportional to the population of cities or towns along the traffic route. Shares of traffic were determined using multiple regression formula based on the traffic service factors in nine urban areas in Japan. The present method was applied to the Tokyo urban area and local core cities which were compared with the actual number of commuting persons. When an urban area is formed around a megapolis, this model is applicable.
