In Korea, the total number of vehicles was 8,470,000 in 1995, but it has increased to 17,033,715 in June 2009. The massive increase of the number of vehicles on the roads have caused serious social and environmental problems. The major underlying problems which we are now suffering from are traffic congestion, traffic accident and air pollution. The motor vehicles are a major source of common air pollutants, including Carbon monoxide (CO), hydrocarbons (HC), volatile organic compounds (VOCs), and oxides of nitrogen (NOx).Many efforts have been made to find approaches which would lead to the solution of transportation problems. The main approaches are constructing road infrastructure, installing Intelligent Transportation Systems(ITS), and providing an efficient traffic operation. Normally, many traffic problems such as traffic accident, congestion and air pollution on roads occure at the intersections and they can be mitigated by changing Traffic Signal Intersection to Roundabout.In this study, various strategies on facilities improvement, operation and policies, have been considered to construct a "Low Carbon, Green City" and the best efficient method which is cost-effectiveness has been proposed for the intersection in rural cities. According to the analysis, the traffic volumes at intersections costal city of Yeosu are quite small, and most of the current intersections can be changed to the "Roundabout" type. However, there is currently no rule and regulation for driving in roundabout in Korea. It is prerequisite to make a law in which driving rule and the travel priority in roundabout are defined. Moreover, in order for the rules to be effective any proposed rules for driving in roundabout must be advertised to the drivers.
