Roads can be divided into urban roads and rural roads depending on their geometry and utilization characteristics. Roads should be designed to meet their characteristics to improve traffic safety and efficiency. However, when designing urban roads and rural roads, engineers use ｢Regulation for the standards of the structure and facilities of roads｣ regardless of the characteristics of roads. Most of these standards are not suitable for urban road design because the regulation provide design specifications that reflect characteristics of rural roads. This problem has been constantly raised, and there has been an attempt to develop design guidelines for urban roads. However, there are no guidelines for designing urban roads so far, and still use the ｢Regulation for the standards of the structure and facilities of roads｣. In addition, the problem is more serious for collector roads and distributor roads, which have “community road” characteristics rather than roads that focus on the mobility of vehicles, such as arterial roads and sub-arterial roads, In this study, “community road” of in urban area is defined, and the design standards that are ambiguous or unfavorable to apply the ｢Regulation for the standards of the structure and facilities of roads｣ to urban roads are reviewed and improved.
