Social infrastructure like public roads are basically provided for all people without differentiating expected benefit of road users. However, recent traffic condition in urban area, especially in large cities, is extremely congested and overall social utility is decreased by uncontrolled and enormous amount of road traffic. Therefore, it is important to improve overall efficiency of road use by introducing reasonable economic regulation in order to save energy as well as to improve environmental condition in such area. In the paper, we investigate the possibility to improve efficiency of roads by putting a surcharge to road users. In the study, social utility of roads is defined as the total amount of expected profits by road users, and assuming various types of potential demand functions, the effect of surcharge to maximize the social utility is investigated by simplified simulation study. From the results, it is verified that introduction of such charging system will improve total utility in most cases regardless of demand types. This concept will be effectively available also for other types of social infrastructures.
