“…We adopted the 2-step floating catchment area (2SFCA) method to calculate the accessibility score for each of the 4245 census tracts in Florida. The 2SFCA method was introduced by Luo and Wang (2003) and has been widely used to explore spatial accessibility to numerous types of facilities, such as primary health-care physicians (McGrail and Humphreys 2014), food (Dai and Wang 2011), greenspace (Xing et al 2020), among numerous others (Chen and Jia 2019). The 2SFCA is a popular method, as it incorporates both supply and demand into its measure of spatial accessibility (Hu and Downs 2019).…”

Massive and rapid testing is crucial for containing the spread of COVID-19. Health and policy planners must ensure that access to and uptake of SARS-CoV-2 testing is adequate and equitable. This study measures the spatial accessibility to testing sites in Florida at the census tract level at the end of May 2020, using the 2-step floating catchment area method that integrates both driving and walking modes. Accessibility scores were found to be heterogeneous across geographic regions and among different groups of people. In particular, many rural areas were in a testing desert. While people in larger cities tended to have better accessibility to testing, many did not have adequate accessibility at that time due to both capacity limitations and spatial factors. In particular, people without access to private vehicles and the elderly faced disadvantages in accessibility to testing sites even in urban areas. However, Black and low-income groups were disproportionally concentrated in neighbourhoods with above-average accessibility due to their closer proximity to testing sites. These results suggest that increased efforts are needed to reach vulnerable populations, including the elderly and those without private vehicles.

“…Large or medium-sized parks (area more than 0.1 km 2 ) have multiple entrances, which will affect the estimated results of accessibility of parks, especially in urban parks, topic parks and district parks. Recently, some articles realized the effect of multiple entrances on the park's service scope and used the entrances to calculate accessibility [41,43,44]. Nevertheless, they did not pay particular attention to the impact of the entrances on the entire service area of the park and on the attainable accessibility of demand points.…”

Parks are an important component of the green infrastructure in cities. They provide multiple benefits for residents’ life. Due to the uneven spatial distribution of parks, it is necessary to evaluate the spatial disparity about residents’ access to parks. The two-step floating catchment area method is suitable for measuring the accessibility of urban parks. However, few studies have noticed the representative of entrances of parks, especially adding them into the process of accessibility measurements. The floating catchment area is often determined by road speed and empirical travel time. In this article, the impact of multi-entrances of the park will be considered and real-time travel time is used in calculating accessibility. In a case of multi-entrance parks in Beijing, the average travel time of the sub-district is calculated, and with the support of the modified method, the spatial accessibilities of car driving, public transport and car-public transport mixed travel modes are obtained. The results show that the time–space compression effect of car driving is more obvious and the mixed travel mode presents the advantage of high accessibility index. This study has a theoretical and practical value for urban planning, such as advising urban planners on the siting of green park space.

“…Previous studies have examined the accuracy and sensitivity of the 2SFCA model [ 78 , 79 , 80 , 81 ]. The results of the E2SFCA method proposed by Kanuganti et al were compared statistically with the observed accessibility values collected via a questionnaire survey and an acceptable absolute percentage error (<10%) was found in all the districts [ 78 ].…”

“…The results of the E2SFCA method proposed by Kanuganti et al were compared statistically with the observed accessibility values collected via a questionnaire survey and an acceptable absolute percentage error (<10%) was found in all the districts [ 78 ]. The results of the 2SFCA model and its different improved models can be different, but they all exhibited a strong mutual correlation [ 79 , 80 ]. The research by Luo et al in 2012 involved both rural and urban areas, which performed oppositely in the sensitivity test on population threshold, but the accessibility changes of different thresholds were consistent [ 81 ].…”

Due to the rapid increase in the number of elderly people in Chinese cities, the development and planning of aged care facilities, and particularly community care facilities, which will gradually become the mainstream choice for the elderly in China, is becoming an important topic for urban sustainability. Previous studies have shown that the number and scale of aged care facilities in many cities are far from meeting the needs of the elderly and the overall occupation rate is low. Some of these cities are still expanding and some are undergoing urban renovation. In this process, the scientific planning of community care facilities to promote efficient use of facility resources has become an urgent problem that needs to be solved. In this study, the two-step floating catchment area (2SFCA) method and a potential model based on the Geographic Information System (GIS) were used to carry out a scientific evaluation of the spatial accessibility of community care facilities in the Beilin district of Xi’an. The aims were to explore the best quantitative research methods for assessing the distribution of Xi’an community care facilities’ spatial accessibility, provide ideas for similar studies in the future, and further the understanding of spatial allocation of urban community care facilities resources.
