This study analyzed the accessibility and service area of public spaces and facilities to develop pedestrian network in Chuncheon city based on GIS and Space Syntax. The followings are the results; Firstly, as reviewing the analysis, the service area ratio by public spaces and facilities is low approximately 20% in Chuncheon city. It present the access of public area is not smooth and the accessibility analysis also shows disconnection between service area and street having high accessibility at some public facilities. So It is demanded development of pedestrian network and consturction of new public facilities to improve them. Secondly, as reviewing the analysis by administrative district, despite high service area ratio, the street having high accessibility is lack to connect between inner and outer area of administrative district at adjacent district to CBD. So these districts are needed development of main pedestrian mall on the inside. Especially, though Seoksa and Toegye districts have high population and facility density, service area ratio is low. So It is demanded improvment of connection with neighbor area or movement of public facility to another area because the access is not smooth. Thirdly, districts where located in the boundary of urban area present low service area ratio. Especially Geunhwa and Hyoja 2 districts have streets having high accessibility but it is not easy to access the public spaces and facilities because the service area is unequal distribution due to Camp Page site and university. Therefore These districts should be improved a connection of pedestrian network and developed large sites such as Camp Page and university to access the general public.
