This study aims at finding the planning consideration to reduce the pedestrian fatalities in Detached Housing Area, DHA. DHA is known as dangerous place to pedestrian in Korea. From 2011 to 2014, Roads less than 9 meter wide, are responsible for 53% of total pedestrian fatalities and they are usually installed in DHA. It indicates that improving pedestrian safety in DHA is important to reduce overall pedestrian fatality rate. It is known that the Screen Effect caused by street parking leads to road crashes between crossing pedestrians and running vehicles. Speeding is another cause of pedestrian accidents.
This situation is more serious in urban residential areas if they have restaurants, cafes and commercial shops.

The report first explains the development process of DHA in term of site planning, design and construction. The major problem is the development process which do not considerate safety of pedestrians sufficiently in the planning, design and operation phase of DHA. The paper presents four strategies designed to resolve the problem:
Pedestrian oriented street network; i.e. Pedestrian friendly street design, Parking lots sharing amongst residents, Maintenance of public space by representatives of residents. Pilot application of four development strategies in designing DHA in a new town shows that they can increase development costs a little but it can increase social benefit including less fatalities.
