Popular concepts in urban planning, like the 15-minute city, suggest that everyday services should be accessible to everyone within "walking distance". However, walking distance is usually considered from perspective of average person, and little effort made understand temporal (daily seasonal) variation accessibility. If our aim create inclusive cities, we also need address realities vulnerable population groups. In this study, analysed how accessibility landscapes vary temporally between...
The coronavirus disease 2019 (COVID-19) crisis resulted in unprecedented changes the spatial mobility of people across societies due to restrictions imposed. This also unexpected and population dynamics that created a challenge for preparedness, including from cities during underlying phenomenon multi-local living. People changing their residences can spread virus between regions create situations which health emergency services are not prepared increase. Here, our focus is on urban–rural...
Our societies struggle to provide a good life for all without overconsuming environmental resources. Consequently, scholarly search approaches meet and social goals of sustainability have become popular. In transport research, accessibility is key tool characterise linkages between people, transport, land use. the current paper, we propose conceptual framework measuring just within planetary boundaries. We reviewed studies discovered substantial literature body on disadvantage, much vaster...
Given different advances in applied literature, risky and positive behaviours keep gaining ground as key contributors for riding safety outcomes. In this regard, the Cycling Behaviour Questionnaire (CBQ) represents one of tools available to assess core dimensions cycling behaviour their relationship with road outcomes from a behavioural perspective. Nevertheless, it has never been psychometrically approached through cross-cultural Therefore, study aimed perform validation CBQ, examining its...
Urban travel exposes people to a range of environmental qualities with significant health and wellbeing impacts. Nevertheless, the understanding travel-related exposure has remained limited. Here, we present novel approach for population-level assessment multiple active travel. It enables analyses (1) urban scale variation, (2) alternative routes' potential improve levels per type, (3) by combining exposures. We demonstrate approach's feasibility analysing cyclists' air pollution, noise,...
Although most actions aimed at promoting the use of active transport means have been conducted in 'large' cities, recent studies suggest that their cycling dynamics could hinder efforts put into infrastructural, modal share, and culture improvements. The present study to assess role city sizes on riding behavioral crash-related outcomes an extensive sample urban bicycle users. For this purpose, a full 5705 cyclists from >300 cities 18 countries responded Cycling Behavior Questionnaire (CBQ),...
Urban greenery has been shown to impact the quality of life in our urbanizing societies. While is traditionally mapped top-down, alternative computational approaches have emerged for mapping from street level mimic human sight. Despite variety these novel approaches, it remained unclear how well they reflect perception reality. We compared a range both and traditional methods with self-reported urban at randomly selected study sites across Helsinki, capital Finland. The included image...
Recent studies have incorporated human perspective methods like making use of street view images and measuring green in addition to more traditional ways mapping city greenery [1]. Green describes the relative amount vegetation visible at level is often measured with index (GVI), which percentage a image or certain location [2]. The dataset Helsinki was created as part master's thesis Akseli Toikka University [3]. We calculated GVI values for set locations on streets using Google Street View...
Promoting environmentally and socially sustainable urban mobility is crucial for cities, with greening emerging as a key strategy. Contact nature during travel not only enhances well-being but also promotes behaviour. However, the availability of greenery varies, recently have new datasets computational approaches made it possible to compare conditions in distribution within between cities quantitatively. In this study 43 large European we undertook comparative analysis by using...
Bike-sharing systems (BSS) have rapidly been established in many cities worldwide. The benefits that potentially provide are increasingly debated with concerns the BSS may mostly benefit limited groups of citizens. Understanding how, when and by whom these used help to plan system be widely employed inclusive. Trip data generated among more analysed types literature, as they often readily available for scholarly use. Most often, trip study origins destinations trips their spatial patterns....
Abstract Recent years have seen a massive development of geospatial sensing systems informing the use space. However, rarely do these inform transformation towards urban sustainability. Drawing on four global case examples, we conceptualize how passive and active should be harnessed to secure an inclusive, sustainable resilient transformation. We derive principles for stakeholders highlighting need iterative dialogue along loop, new modes governance enabling direct feeding sensed...
Riding a bicycle is increasingly encouraged as sustainable transport solution, especially in urban areas. However, safety concerns, both perceived and actual, can significantly lower the willingness to ride among population. To support cycling planning policy double task of increasing levels while mitigating crash risk, there need better understand behaviours attitudes riders. In this manuscript, we study cohort Finnish riders through four questionnaires, Cycling Behaviour Questionnaire...
Our societies are wrestling with the problem of how to provide a good life for all without overconsuming environmental resources. Consequently, search approaches that simultaneously inspect and social goals sustainability have become increasingly popular in many disciplines. In transport research, accessibility is key tool characterize linkages between people, transport, land use. current paper, we propose conceptual framework measuring just within planetary boundaries. We first carry out...
This Data in Brief (DiB) article presents the differences cycling behaviors related to violations, errors, and positive by region. The study data were collected means of a structured questionnaire applied full sample 7,001 participants from 19 countries, distributed over 5 continents. paper proposes descriptive statistics, as well common statistical tests. aim is enable authors make their own analyses, not provide precise interpretations. For further information about macro project...
Travel times between different locations form the basis for most contemporary measures of spatial accessibility. allow to estimate potential interaction people and places, is therefore a vital measure understanding functioning, sustainability, equity cities. Here, we provide an open travel time matrix dataset that describes centroids all cells in grid (N = 13,132) covering metropolitan area Helsinki, Finland. The recorded follow door-to-door approach provides comparable walking, cycling,...

The visual appeal of urban environments significantly impacts residents' satisfaction with their living spaces and overall mood, which in turn, affects health well-being. Given the resource-intensive nature gathering evaluations on through surveys or inquiries from residents, there is a constant quest for automated solutions to streamline this process support spatial planning. In study, we applied an off-the-shelf AI model automate analysis appeal, using over 1,800 Google Street View images...
