For decades, accessibility – i.e. the ease of reaching destinations – has been an important concept in transport planning, resulting in many studies trying to measure it and put it into practice. Also walkability, a mode-specific type of accessibility referring to how easy it is to walk (to destinations) received increased attention in the last two decades. In recent years, a new focus has been on how people perceive their accessibility as this may be a stronger predictor of travel behaviour than objective elements of accessibility (such as built environment characteristics). Perceived walkability, i.e. how walk-friendly people experience a certain area, however, has only been explored by a limited number of studies. In this review paper, we give an overview of existing studies analysing perceived walkability, which mostly have focused on its effects on walking frequency/duration, physical activity and various aspects of mental well-being. Based on this literature review, a conceptual model is created, emphasising the determinants and effects of perceived walkability and how it is related to objective walkability. We end this paper by providing avenues for further research, including the introduction of a Short Perceived Walkability Scale (SPWS) and recommendations for data collection and analysis. Doing so can create new insights into perceived walkability and links with related elements, and therefore can contribute to stimulating walking trips and improving the experience of these trips.

A sustainable development of urban transportation relies on our ability to offer citizens reliant and attractive alternatives to car travel, such as efficient and appealing public transport (PT) services, alongside an urban environment that is stimulating for active travel alternatives, such as walking and cycling

Walkability is an important indicator of sustainable urban development, especially in fragmented historical blocks affected by modern development efforts. Xi’an, China, and Kyoto, Japan, which are among the oldest cities in Asia, have similar historical backgrounds and a grid-based street network that differs from European historical cities. They also have their own distinctive development characteristics. This study uses a novel quantitative approach to identify areas for improvement in the historical built environment of the two cities that, as part of an overall effort to create a pedestrian-friendly urban center, will promote and facilitate walking activities. The proposed method combines macro- and micro-aspects to identify factors that can either improve or hinder the walking environment. It was found that to ensure a walkable environment in its historical blocks, Xi’an will need to consider the potential negative impact on walkability as it pursues increased modernization. The built environment and the infrastructure of its streets need to be improved, and its historical streetscape and vegetation characteristics need to be maintained. As for Kyoto, to ensure a favorable walking environment, the focus should be on improving the vitality of its streets.

The role of green infrastructure (GI) in regenerating brownfield sites has not yet been widely recognised in Japan. In contrast, post-industrial countries in Europe and North America have introduced a number of good practices for GI-led brownfield regeneration. Using GI to revitalise post-industrial areas offers multiple benefits, ranging from ecosystem restoration and increased property values, to improvements in personal well-being, and can serve as an effective climate change adaptation solution. In Japan, nature has traditionally been used to protect the built environment from disaster; for example, preserving forests to prevent landslides, or sand or wind erosion on the coast. Although the application of GI is not a new idea in Japan, its role in revitalising brownfields and building communities has not been widely discussed. This paper explores the potential role of GI-led brownfield regeneration in Japan. Key barriers and drivers in revitalising post-industrial sites through the use of GI are identified using three case studies from the Osaka Bay Area, home to some of Japan’s largest brownfield sites. The paper concludes with highlighting opportunities and challenges for disseminating the concept of GI-led regeneration in the Japanese context.

The COVID-19 pandemic has greatly affected the mobility of individuals everywhere. This has been especially true in China, where many restrictions, including lockdowns, have been widely applied. This paper discusses the impact of the pandemic on walkability, an important factor in promoting urban neighborhoods, in the main urban area of Xi’an, China, one of China’s four great ancient capitals. Based on the street view data obtained before and after the pandemic, the paper quantitatively compares changes in specific components of selected streetscapes through a deep learning (DL) street view analysis. The aim is to identify the impact of the pandemic on walkability and determine the elements that influence increased walkability in Xi’an’s historical area, using a walkability evaluation model based on a regression analysis involving three factors (streetscape components, walkability check scores, and street connectivity of space syntax for every image). Although Xi’an’s urban structure did not change significantly, the pandemic has clearly impacted street vitality, especially in terms of reducing pedestrian flow and commercial value. Based on study results, the street environment has great room for improvement, especially in the city’s historical blocks, by reconsidering safety measures to pedestrians and the important role of atmospheric aspects on the streets.

This paper presents results and policy implications from RAISE-IT, an EU Connecting Europe Facility (CEF) funded project. It examines the integration of long-distance rail with local and regional transport networks at key urban nodes along the Rhine-Alpine Corridor, one of the nine Trans-European Core Network Corridors (CNCs). It is crucial to foster seamless and suitable passenger transport solutions to achieve emissions goals and support the decarbonization process. Consequently, the whole travel chain needs to be considered and good interconnections with other transport modes are needed. For this reason, RAISE-IT explored multi-spatial scale accessibility. It considered three spatial scales (local, regional, and corridor-wide) and looked into multiple travel distances and needs along the corridor for accessing and minimizing the gap between highly and less accessible railway stations with reference to multi-scale travel patterns. This approach revealed overlapping issues between cross-regional and local decision makers and facilitated opportunities to discuss challenges and areas for improvement. The results formed the basis for guidelines on how to improve the accessibility of urban nodes and the quality of services and connections provided at railway stations. This paper discusses potential transferability aspects and recommendations for policy implications from RAISE-IT for railway stations and urban nodes in other CNCs.
