Pedestrianization (converting streets to car-free zones) is a practical strategy to reduce car dependency, promote active transportation, and enhance urban livability. However, many city residents and business owners have often opposed pedestrianization. Through a cluster analysis, this study examined opposition to pedestrianization in Montreal, Canada. To this end, an online survey was designed and administered. The collected data (1909 complete responses) was synchronized with five contextual data sources to form a large-scale dataset, including 121 variables. The results suggested that opposition to pedestrianization was associated with insufficient satisfaction with 2-wheelers/pedestrian cohabitation, attractiveness, urban furniture, cleanliness, and safety of pedestrianized streets. The supporters tended to change their travel behavior to spend more time in car-free streets, while opponents tried to change their route to avoid traveling in vehicle-free zones. The opponents included more non-cyclists, males, car owners, older people, and those living alone in neighborhoods with lower density. Opponents were more likely to be drivers and taxi users. This study highlights how pedestrianization can reduce motorized vehicle use while increasing active transportation. These insights can help policymakers address public concerns and create urban spaces that better accommodate all road users.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"165 ","pages":"Article 106178"},"PeriodicalIF":6.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144490518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combining concepts from game theory and institutionalism, this article examines how the path-dependent practice of public funding discourages private beneficiaries from contributing collectively, while the free-rider problem discourages them individually. We apply process tracing to unravel the mechanisms by which these barriers were overcome. The case suggests that beneficiaries can rationally decide to contribute collectively, but only if this decision contributes to a goal that is highly desirable and urgent to them, and no more beneficial options are available. While the case also indicates that the free-rider problem can be overcome through normative pressure, the evidence suggests that this requires the existence of a homogeneous, tight-knit group of beneficiaries in which private funding contributions match pre-existing norms. These results help explain why few governments succeed in implementing private sector funding contributions, and provide starting points for changing this.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"165 ","pages":"Article 106169"},"PeriodicalIF":6.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144480120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing a hybrid thematic analysis based on 21 semi-structured in-depth interviews, the research discusses residents' behavioural adaptation, encompassing personal, technological, and cultural adjustments, along with their associated spatial dependencies. Findings indicate that adaptation practices occur across various spatial scales, with personal and technological adjustments primarily reliant on the house unit, while cultural adjustments extend to neighbourhood scales and beyond.

However, the role of built environments in driving aggregate-level intra-urban migration in Sydney, which is crucial for assessing urban planning effectiveness, remains insufficiently understood. This study examines Sydney's intra-urban migration patterns from 2006 to 2021 and applies the gravity model and Multiscale Geographically Weighted Regression (MGWR) model to identify built-environment-related push and pull factors while accounting for spatial variance. The findings reveal that: (1) Intra-urban migration intensified in Sydney, particularly in the west. (2) Sufficient housing, more detached dwellings, and less non-private housing in the destination incentivized population inflows, while these same attributes at the origin discouraged outflows. Spatial variations in migration drivers were observed: detached housing discouraged short-distance inflows but promoted long-distance inflows. West-to-east movers tended to relocate to areas with fewer detached homes but more owner-occupied housing, while westward movers displayed an opposite trend. The relationship between schools and relocation also exhibited east-west spatial variance, potentially linked to the lower quality of education in the west. The study suggests that the city government consider a differentiated spatial housing market to meet different needs and enhance efforts to improve the quality of urban infrastructure in the west to address spatial inequality.

Therefore, this work aimed to investigate the effects of automobile ownership on travel mode choices where e-scooter was an option. A stated preference survey was prepared, and responses were collected from individuals in Istanbul about the mode choices, namely private transport, public transport and e-scooter. The method used to model the travel choices was Mixed Logit (ML). Two approaches were made to observe the effects of automobile ownership: Dummy variable and market segmentation. Both approaches proved that automobile ownership affected the e-scooter choices over other modes, and different models can be developed for individuals who owned automobiles and others. Results showed that there were taste variations regarding travel time among the individuals, and travel time affected the choices of automobile owners more than the others. However, no taste variations were observed regarding travel cost. Furthermore, under congested traffic conditions, the breakeven e-scooter fare was lower for automobile owners for the switch between private transport and e-scooter. In addition, cost elasticities indicated that automobile owners were more sensitive to e-scooter cost changes.
