For this purpose, axial lines were produced by applying space syntax theory, Depthmap software. The research aims to verify the location of open spaces and facilities, such as schools, in relation to the location of public transportation stops （bus, metro and tram）, in order to check their accessibility within walking distances. The objective is to pay attention to the relationship between land use and transportation in the planning phase for future interventions or proposals, in other words, to improve the accessibility of public spaces or buildings by pedestrians in order to comply with the vision of the Abu Dhabi 2030 Master Plan and its promotion of walkability and cycling. Although many measures will be taken at the scale of urban design to provide shaded open spaces and sidewalks, saving pedestrians from walking long distances shall be done in the planning phase, the challenge remains to create a micro climate to increase the ease of walking in the heat and decrease dependence on cars for mobility.展开更多

Research to date, however, has not presented relevant evidence to support this hypothesis or explained how to identify the concept of ‘remoteness'. Resource-exhausted cities designated by the State Council of China were examined in this study alongside the provincial capital cities that contain such entities and three regional central cities that are closely connected to this phenomenon: Beijing, Shanghai, and Guangzhou. Spatial and temporal distances are used to calculate and evaluate the location remoteness degrees(LRDs) of resource-exhausted cities, in terms of both resource types and regions. The results indicate that resource-exhausted cities are indeed remote from the overall samples. Based on spatial distances, the LRDs are α_1 = 1.36(i.e., distance to provincial capital city) and β_1 = 1.14(i.e., distance to regional central city), but when based on temporal distances, α_2 = 2.02(i.e., distance to provincial capital city) and β_2 = 1.44(i.e., distance to regional central city). Clear differences are found in the LRDs between different regions and resource types, with those in western China and forest industrial cities the most obviously remote. Finally, the numbers of very remote resource-exhausted cities based on spatial and temporal distances(i.e.,α > 1.5 ∩β> 1.5) are 14 and 19, respectively, encompassing 17.9% and 24.4% of the total sampled. Similarly, 25 and 30 not remote resource-exhausted cities based on spatial and temporal distances(i.e.,α≤1.0 ∩β≤ 1.0) encompass 32.1% and 38.5% of the total, respectively. This study provided supporting information for the future development and policy making for resource-exhausted cities given different LRDs.展开更多
