“…The concept of accessibility was first introduced by Hansen in 1959, who defined the concept of accessibility as the magnitude of opportunities for nodes in a transportation network to interact with each other [1] . Accessibility, as an important indicator of the functional efficiency and spatial equity of regional spatial structures, has been widely used in fields such as regional development and transport planning [2,3] . Meanwhile, in the field of public service facilities research, the spatial accessibility evaluation method can identify the scarcity of public services in these areas, which is a measure of the layout of public services and facilities space equity and is an effective way to measure the layout of facilities [4,5] .…”

It is of great significance to optimize the spatial matching of basic education facilities in rural areas and promote the equalization of urban and rural basic public services and the overall revitalization of rural areas. Based on the theory of spatial accessibility and spatial balance of supply and demand, this paper constructs the evaluation system of rural basic education facilities and layout rationality. In this study, we took 42 primary and secondary schools and 2089 rural areas with concentrated population in six township areas of Hancheng City as the research subjects. We used ArcGIS network analysis, population coupling model, and other methods, from the administrative scale and rural population concentration area scale for evaluation. The accessibility of basic education facilities and its coupling relationship with the spatial distribution of student population describe the spatial and geographical pattern of basic education facilities in rural areas. The results show that the accessibility of rural administrative scale and the spatial balance of supply and demand of population concentration area scale are associated with great problems, the differences between towns are obvious, and the overall level of the best performing towns is still low. On the scale of population concentration area, the overall coupling degree is too low, the “dislocation” distribution of educational facilities and student population is obvious, and the matching degree of the student population and school in different towns is significantly different, showing a more obvious “core-periphery” spatial structure characteristics centered on the eastern and southeast regions. The terrain characteristics of rural areas in Shaanxi province are prominent, and the accessibility of the road network is particularly significant. Therefore, optimizing the construction of rural roads and optimizing school layout according to local conditions will become an important solution to promote the balanced allocation of basic education resources in Shaanxi province.

“…In contrast, the gravity model reflects the attraction of the endpoint to the starting point through a certain degree of supply and demand [6]. Among the location-based accessibility measurement models, the opportunity model is most widely applied in planning practice, along with the measurement standards highlighting mainly the total opportunity available within a certain cost or the total cost required to obtain certain opportunities [7]. As the concept of accessibility is commonly used in many fields, some interdisciplinary methods have been proposed.…”

The reasonable accessibility assessment method is an important basis for the measurement of the level of prehospital emergency medical services. There is no general model for prehospital emergency care in traditional accessibility evaluation, and its supply-demand characteristics have also been ignored. Based on the three-step floating catchment area (3SFCA) model, the supply-demand three-step floating catchment area (SD3SFCA) model is proposed in this paper, which can express the difference between supply and demand of prehospital emergency medical services and accurately simulate unified dispatching of emergency centers. The unified dispatching behavior of emergency centers is simulated based on the potential service capacity of emergency stations with a supply-demand difference. The supply capacity of different emergency facilities is quantified from the perspective of infrastructure and technical quality. The needs of typical population densities are taken into account and adjusted by the weighting index. The validity of the model is verified, with the prehospital emergency medical service in the West Coast New District of Qingdao as an example. The results show that the model can effectively measure the accessibility level of prehospital emergency services and truly reflect the characteristics of supply and demand. Compared with previous models, the model has been significantly improved, which can provide an important reference for optimizing the allocation of prehospital emergency resources.

“…Arguments for location-based school catchment assignment are driven by a number of objectives, which include improving education accessibility [39][40][41], spatial equity [42,43] and containment of travel within neighborhoods or metropolitan subregions [41,44]. The long-term effects of spatially equitable access to education facilities and overall shorter school-trip distances have strong sustainability implications, notably from the aspects of urban development, public health and environmental protection.…”

Active school commuting provides a convenient opportunity to promote physical activity for children, while also reducing car dependence and its associated environmental impacts. School–home distance is a critical factor in school commuting mode choice, and longer distances have been proven to increase the likelihood of driving. In this study, we combine open-access data acquired from Baidu Map application programming interface (API) with GIS (Geographic Information System) technology to estimate the extent to which the present school–home distances can be reduced for public middle schools in Jianye District, Nanjing, China. Based on the policies for school planning and catchment allocation, we conduct a scenario analysis of school catchment reassignment whereby residences are reassigned to the nearest school. The results show that, despite the government’s ‘attending nearby school’ policy, some students in the study area are subjected to excess school–home distances, and the overall journey-to-school trips can be reduced by 20.07%, accounting for 330.8 km. This excess distance indicates the extent to which the need for vehicle travel can be potentially reduced in favor of active school commuting and a low-carbon lifestyle. Therefore, these findings provide important insights into school siting and school catchment assignment policies seeking to facilitate active school commuting, achieve educational spatial equity and reduce car dependence.
