Summary: This paper takes the Shijingshan District in Beijing as an example and simulates and analyzes the accessibility of rail stations based on the Gaussian two-step floating catchment area method and Gaode map's service interface. By examining the supply and demand relationship and trip time, the current characteristics and causes are analyzed, and corresponding optimization suggestions are proposed. The study shows that the accessibility of rail stations in the Shijingshan District is relatively coordinated with population distribution and the change of trip mode has a small impact on the accessibility of large stations. Comprehensive accessibility is positively correlated with road density and population density.

Summary: This study proposes an improved multi-mode 2SFCA method to accurately measure urban park accessibility, using residential areas in the central city of Tianjin as the spatial unit. The results indicate that as the travel time from residential areas to urban parks increases, the urban park accessibility decreases. This study provides a comprehensive and realistic insight into understanding urban park accessibility.

Summary: This study explores residents' spatial preference for urban forest parks and finds that residents tend to prefer forest routes. Although familiarity with the spatial image preference for urban forest parks varies from person to person, there are certain commonalities in route selection among residents. Residents' route preference is influenced by their exercise habits, environmental preference and residential location.

Summary: This study aims to evaluate park accessibility using an improved method, taking into consideration different travel modes. The results show disparities between park supply and population demand, and the improved method provides a more sensitive and realistic assessment of park accessibility. The accessibility of parks varies with time and mode of transportation, with the smallest accessibility difference between residential areas in the 30-minute scenario. Overall, park accessibility is relatively high, but decreases gradually from the park center, with regional variances in spatial equity.

Summary: With the prevalence of MaaS systems, route choice models need to consider unique characteristics such as "congestible capacity". An offline-online estimation method is introduced to capture the structural effects that flows have on capacities and their impacts on route choice utilities. This approach allows for monitoring and quantifying impacts to traveler consumer surplus in real time.

Summary: Ensuring equitable access to urban parks is crucial for promoting the sustainable development of cities. This study introduces an improved two-step floating catchment area (2SFCA) method to accurately assess park accessibility and spatial equity in Guangzhou, considering the 15-minute city perspective. The results reveal unequal park accessibility in Guangzhou, with low-access areas mainly distributed on the fringe of study area in both walking and cycling scenarios due to the limited park supply or high-density population. The work enhances the understanding of park accessibility and facilitate effective planning for sustainable development and reducing environmental injustice.

Summary: Floods are a frequent and devastating disaster in Nepal. This study provides a comprehensive mapping of flood susceptibility and evacuation routes in the Siraha Municipality of Nepal, utilizing GIS and AHP. The study identifies areas highly susceptible to floods and selects assembly points for evacuation within those areas. Emergency shelters are chosen in safe zones to accommodate a maximum number of people. The study also proposes optimal evacuation routes based on walking speed and analyzes possible areas for additional shelter placement. It can be valuable for flood risk assessment, early warning system planning, and efficient evacuation planning.

Summary: This study proposes a scenario analysis framework using ES mapping, ES scoring, and economic analysis technology to evaluate soil and water conservation practices in agricultural watersheds. The results show that some SWC practices can affect the value of ES indicators, while others do not have a clear trend. The study also identifies the relatively optimal scenario based on ES scores and economic-benefit trade-offs.

Summary: Land use change is an important factor affecting ecosystems, and simulating future land use changes under different scenarios can test the rationality of such changes. The study found significant spatial heterogeneity in land use changes in the Beibu Gulf area, and the ecotourism development scenario was considered a more reasonable model for development.

Summary: This study focused on the spatial aspect of medical resources and residents' mobility in Wuhan during the COVID-19 pandemic. By estimating the travel distance and time from communities to medical facilities capable of treating COVID-19 patients, significant differences in service areas and potential loading across medical facilities were identified. The study indicated spatial inequalities in medical resources within and across districts, and highlighted the need for re-evaluating the coordination of emergency responses for future planning and utilization of medical facilities.

Summary: The study simulated the wind environment of primary schoolyards in Nanjing using computational fluid dynamics and evaluated wind comfort criteria. The results showed that the comfortable wind environment generally expanded in summer and winter, but decreased in some outdoor spaces. The study also found that the mean wind speed did not correlate linearly with building density, and increased building height improved wind comfort in schoolyards but worsened it in the vicinity.

Summary: Public sports facilities are important for citizens to exercise and lead an active lifestyle, and their distribution plays a critical role in the planning of healthy and active cities. Using Nanjing, China as a case study, we found spatial inequity and insufficient number of public sports facilities in the area. These findings highlight the disparities in physical activity opportunities among citizens.

Summary: This research aims to explore the feasibility of promoting scientifically designed daily exercise routes using public sports facilities, green spaces, and bicycle lanes. The study on 25 major public sports facilities in Nanjing reveals that these facilities can provide services to most residential areas and have potential interactions with parks. Therefore, designing reasonable daily exercise routes coupled with the existing facility layout is feasible, but considerations need to be given to the facility layout, bicycle lane density, green space configuration, and official planning proposals.

Summary: This study highlights the significant impact of distance between home and school on children's active travel to school in Nanjing, China. The study suggests that urban form, particularly gated communities, can result in longer and less direct routes for students. By implementing through access as a management option and opening new entries as a reengineering option, school travel distances can be shortened with minimal costs, providing potentially safer routes for students.
