“…For example, the Euclidean distance measurement method was used to evaluate the spatial pattern of facility accessibility [3], but the study completely neglected a large number of water bodies and mountains that were located along the path of the Euclidian distances measured in the study area. In some studies [16,25,28,31,32], the average time of travel as recorded in the government statistics was used as the transportation cost in the network analysis. They also added distance walked to reach the destination to improve the accuracy of accessibility [25].…”

The accessibility of hospital facilities is of great importance not only for maintaining social stability, but also for protecting the basic human right to health care. Traditional accessibility research often lacks consideration of the dynamic changes in transport costs and does not reflect the actual travel time of urban residents, which is critical to time-sensitive hospital services. To avoid these defects, this study considered the city of Kaifeng, China, as an empirical case, and directly acquired travel time data for two travel modes to the hospital in different time periods through web mapping API (Application Program Interface). Further, based on travel time calculations, we compared five baseline indicators. For the last indicator, we used the optimal weighted accessibility model to measure hospital accessibility for each residential area. The study discovered significant differences in the frequency and spatial distribution of hospital accessibility using public transit and self-driving modes of transportation. In addition, there is an imbalance between accessibility travel times in the study area and the number of arrivals at hospitals. In particular, different modes of transportation and different travel periods also have a certain impact on accessibility of medical treatment. The research results shed new light on the accessibility of urban public facilities and provide a scientific basis with which local governments can optimize the spatial structure of hospital resources.

“…In such social networks, stakeholders are faced with multifarious problems, like loose connections between stakeholders, unbalanced distributions of authorities among government departments, and unreasonable allocations of stakeholder duties [9,[15][16][17][18]. Besides, the lack of supervision for a few institutions, as well as the low-quality of aging services delivered by some vendors, critically hinder the sustainable development of AIP systems [15][16][17][18][19]. The success of AIP systems necessitates a thorough understanding of the characteristics and constraints of AIP stakeholders and the complex relationships among them.…”

China currently has an elderly population of 249 million with over 97% of them ending up aging in place. Although various regional pilot programs have been conducted, a sustainable aging-in-place system has not been established to effectively and efficiently provide aging services in many cities of China. The characteristics of stakeholder networks in the aging-in-place systems have not attracted great attention from researchers. This research applies social network analysis to characterize the interactions of stakeholders in aging-in-place systems to facilitate cooperation and coordination amongst them. Using Nanjing as a case study, 23 stakeholders in Nanjing’s aging-in-place system are identified, such as the Aging Affairs Committee, Aging-in-Place Service Association, and aging-in-place service centers; and then the relationship networks of these stakeholders in terms of communication, supervision, and trust are developed and analyzed. The results show that the aging-in-place system suffers from certain defects, including the loose connection of government departments, redundant information channels, low trustworthiness of certain aging-in-place service centers, poor credibility of third-party training and assessment institutions, and excess power of the industry association. To tackle these issues, a wide spectrum of actionable measures applicable to Nanjing’s conditions, as well as high-level policy implications for other cities of China, are proposed for augmenting the communication, supervision, and trust among stakeholder groups.

Ranging from simple to sophisticated, numerous types of accessibility measures are found in the accessibility modeling literature which helps to understand accessibility of people, place and transportation networks. Transportation network directness (reciprocal is "circuity"), which is defined as the ratio of the shortest Euclidean distance over network distance between demand (origin) and destination (supply) points, could be considered as an important type of measure for understanding accessibility for a variety of context.Although there are several research and literature on transportation network directness and accessibility modeling, the research that integrates transportation network directness concept into accessibility modeling process in such a way to provide understanding of the overall accessibility performance of the transportation networks without losing the local interactions is quite limited.Based on this idea, the basic aim of this research is to propose a new transportation network directness-based accessibility modeling methodology that could be used to test both the local and the overall accessibility performance of transportation networks in a simple and comparable manner by using GIS. By considering regularly produced virtual origins and destinations on the transportation network in a "simulation" manner, the proposed methodology could produce "travel time/distance" based accessibility measures that could operate without a need for real time supply/demand or origin/destination data.The advantage of using a virtual regular data set instead of real time data is that; it is more simple, easy to operate and most importantly, more realistic to understand performance of transportation networks as most of the possible origin/destination scenarios could be represented in the proposed model. The outputs of the model could be widely used by the decision-makers who are supposed to deal with accessibility, location/allocation, and service/catchment area related issues by several aims such as; to test the overall/partial performance of the transportation networks, to understand the weakly connected parts of the transportation network and/or to compare the accessibility performance of different networks with each other.The proposed methodology is applied in 3 cities with different types of transportation network which are Paris, FRANCE (radial network); San Francisco, USA (grid network) and Ankara, TURKEY (mixed network) in order to able to demonstrate the performance and efficiency of the proposed model. The main focus of the case study is not to evaluate specific accessibility conditions or transportation network performance in a detailed manner but to provide a methodological discussion about the proposed directness based accessibility modeling process.
