The purposes of this study are to find out roles which a network of parks and green spaces in Senboku New Town played when senior citizen chose traveling routes to parks, and to explore ways to create a new town with elderly-friendly living environments. The questionnaire survey was conducted to find out the traveling routes taken by senior citizens visiting their most-commonly visited parks and the reasons why they chose those routes. The field survey and analysis of the area maps were carried out to understand the spatial characteristics of the chosen routes. The results of this study showed that the most frequently-used routes were green walks traversing the neighborhood unit from east to west, and that park and green space networks played an important role as routes when senior citizens visit parks. The study also confirmed that the senior citizens cited the shortest way to parks as the best reason when choosing routes to parks, but that they sometimes chose green walks though they are not always the most direct route. It can be considered that barrier-free pathways should be established to help a systematically built new town revitalize in unison with elderly-friendly living environments，and that park and green space networks would serve as important public assets in developing these pathways.
