Roads are an essential part of a social capital and are indispensable for both the economy and society. During the thirty-five years since 1954 when the First Five-Year Road Improvement Programme was introduced, the quality of roads in Japan has improved immensely. However, the increase in the number of automobiles during this period has far exceeded the construction pace of roads and is a major cause of the current growth of traffic congestion. Particularly serious congestion is found in large cities, where it impedes efficient business and comfortable urban life. Consequently, the implementation of extensive measures, including reorganization of the urban structure, is required urgently. In regional cities, major parts of urban activities depend upon motor traffic. Accordingly, the construction of highway networks, such as bypasses and ring roads, is imperative to reduce congestion, to improve urban functions, and to vitalize the area as a whole. This report discusses the background to the attention that has recently been focused on the traffic congestion issue, the current state of the problem, the Construction Ministry's approach to the situation and, in particular, to how it is being monitored. Although it mentions methods additional to road improvements of tackling road congestion, it does not discuss in detail the policy issues these raise. (A)
