If public services are distributed inappropriately and unequally, it could become a factor which prevents the city from sustainable development. Consequently, “Spatial Equity” should be regarded as an important planning concept and be considered in planning process in order to practice the goal of equity and sustainability. In previous research, accessibility measures are common methods to conduct a spatial equity study since they have complete concept of availability and spatial distribution of public services. However, these approaches are zone-based methods, which can’t detect the fine difference within a zone. Therefore, this study took the individual accessibility measure, adopted the centers of road segments as services origin points, counted the shortest distance to closest facility through Network Analysis in the ArcGIS and took it as accessibility value. The study results show that the accessibility of urban parks would produce error if we adopt zone-based method. The Gini coefficient coming from individual accessibility value helped us figure out the integral spatial inequity over Taichung city. It shows that administrative districts in central Taichung have better accessibility. Besides, the spatial inequity could be improved if undeveloped urban parks are constructed. Ultimately, by adding undeveloped park separately, we could gave an overall suggestion of urban parks and confirmed which service is important for integral spatial equity.
