“…For example, Hino et al developed the Japanese Walkability Index (JWI) to measure walkability in cities based on the high-density urban structure of Yokohama. Since the JWI preferentially considers amenities, road networks, and land prices rather than density variables, it is superior for high-density Asian cities ( 55 ). Moreover, the European urban context is distinctive from that of US, which featured with low population density, low land use mix, and connectivity.…”

China's metro system is developing rapidly. Walking is the most frequently adopted mode to connect to the metro, the attributes of the pedestrian-built environment around the stations directly influence people's willingness to use the metro. However, few studies have paid attention to the comprehensive assessments of the built environment in the metro catchment area. Thus, this paper attempts to construct a walkability evaluation model that combines subjective and objective perspectives. We collected field data of the built environment factors affecting on walkability in the 800 m buffer zone of eight case metro stations in Dalian city, China. We also collected on-site interviews from 867 passengers to evaluate the walkability. A machine learning-based approach was developed to calculate the weights of walkability variables, followed by constructing a Score-Effectiveness framework to identify the built environment factors in the metro catchment area that need to be improved. The study found that the shading facilities, obstacle barriers, and resting seats around pedestrian walkways are the most efficient and imbalanced variables recognized by the crowd. The convenience of overpasses and underpasses are additional efficient imbalance-type variables for leisure and commuting populations, respectively. This indicates that the current level of construction of the above five built environment factors is relatively low, but the construction has a significant impact on the degree of friendliness in supporting pedestrian walkability. In this paper, improvement measures are proposed in a targeted manner in order to achieve the effect of effectively improving the current level of metro catchment area's walkability. The results of the study can provide references to provide strategies for precise pedestrian planning in the metro catchment area, leading to a pedestrian environment with high walking quality.

“…Areas with clusters of amenities have high neighborhood walkability, which refers to the proximity to amenities (or walking opportunities) [ 11 ]; a walkable neighborhood promotes residents’ quality of life [ 12 ] and increases its property values [ 13 , 14 ]. Walkability is defined as built environment conditions that encourage walking behavior [ 15 , 16 ].…”

“…Areas with high neighborhood walkability refer to those with a large population ( density ), high street connectivity ( design ), and good access to diverse facilities ( diversity and destination accessibility ) and public transportation ( distance to transit ). A close distance from homes to amenities (measured by facility density within an area, for example) is the most important factor of neighborhood walkability that can be generalizable regardless of the urban structure [ 11 ]. Areas with high street connectivity and easy access to public transportation can further facilitate the access of pedestrians living in those areas to facilities by reducing their travel time to reach their destinations [ 19 , 20 ].…”

“…The newly developed residences in hilly areas have a high sediment disaster risk and are relatively nonwalkable owing to the slopes. Mobility tends to decrease as people age [ 24 ], and the proximity to amenities is especially important for people with limited mobility [ 11 , 12 ]. However, there are few walking opportunities in hilly areas; thus, the cluster of amenities tends to be located on plains [ 21 ].…”

People’s preferences regarding their neighborhood environment can vary depending on their socioeconomic status and the cities where they live. This study aims to discern the relationship between neighborhood environment factors and single-family detached house sales by sale price and by central and noncentral cities. We analyzed sale prices in the Tokyo Metropolitan Area from 2015 to 2020. The neighborhood environment was assessed using flood/sediment risk and neighborhood walkability measured by net residential density, intersection density, and facility density (walking opportunity). Flood and sediment risk is a major concern that restricts the available land and is included as a negative aspect of the neighborhood environment, taking the topographic features into consideration. A comparison of the results showed that the preference for neighborhood walkability varies by socioeconomic status as well as by target cities. For most facility types, the number of walking opportunities within walking distance from houses was found to be positively related to the sale price of single-family detached houses in all quantiles. The relationship of house price with population and intersection density was found to vary depending on the price level, with a negative relationship with the sale price of relatively more expensive houses being exhibited. People who considered buying houses with relatively higher sale prices were found to devalue houses located in flood/sediment-hazardous areas more. However, it was also found that the negative relationship was slightly mitigated in the highest quantile of sale prices for houses in areas with a moderate flood risk (maximum flooding depth: 3–5 m). Plains near rivers with amenities offer high walkability but pose a flood risk, resulting in a trade-off between flood risk and neighborhood walkability. The findings suggest the use of indices representing diverse preferences in accordance with the target socioeconomic status when policymakers assess the neighborhood environment.

“…In order to overcome this gap, some approaches provide sophisticated tools like grid cells, connected to a relevant database (Hino et al, 2022), connecting land uses to focal points or the geometries of walking space (Caseli et al, 2021), or grouping parameters according to the nature of the information (Abastante, et al, 2021). There are also other approaches that base their evaluations on extended questionnaires and individual judgments by different social groups, for example, tourists (Stockton et al, 2016;Bassiri et al, 2021).…”

Sustainable mobility has been considered key in the pursuit of sustainable development in urban environments. During the last decades, a lot of innovative initiatives have been proposed and examined, most of them were site-specific and highly relevant to the local context. This case study review focuses on Nicosia, a car oriented, medium sized city, and attempts to define an intermodal walkability index for the city center. In a city like Nicosia where more than 90% of the daily trips are done completely by car, encouraging intermodal mobility with walking as part of the trip is an important first step to sustainable mobility. The aim of the paper is to present a model based upon the most impactful sustainability indicators when referring to pedestrian mobility, and therefore will create an intermodal walkability index for grading the walkability of an urban environment, in our case a particular, car-oriented one. The index was developed by using the latest version of pyQGIS, due to the fact that the algorithms that are being used in the calculation of this index are already part of the geospatial analysis toolbox contained within QGIS. The paper uses as a case study the municipality of Nicosia in Cyprus where it was proven that pedestrian transportation can be graded in terms of walkability from the private car drop point. The study has also discovered that the use of primary electricity generation and fossil fuels for transport can be reduced if problematic areas that have a low or negative sustainability score are managed in ways that will increase the score.
