The goal of this research is to measure whether the 15- or 30-minute city goals align with current travel behaviour and land use patterns in the North American context using Montreal, Canada as the case study. In doing so, we look at which destinations are cultivating local travel patterns consistent with the 15- and 30-minute city concepts and identify any unique qualities of these areas using the 2018 Montreal origin-destination travel diaries. Our bivariate analysis finds very few destinations in Montreal where a high number of trips and high percentage of trips are ending using a sustainable mode of transport and below the 15- or 30-minute travel time threshold. We further investigate the land use patterns that align with the 15- and 30-minute city to recommend realistic planning goals and policy interventions that match the North American context. The findings from this research can be of interest to transport professionals and policy makers trying to implement the 15- or 30- minute city concepts to their regions.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"5 ","pages":"Article 100076"},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000062/pdfft?md5=e017f77c18e9e4452ca3f538d56e2708&pid=1-s2.0-S2667091724000062-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140321344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploring the 15-minute city concept in Oslo, Norway","authors":"Mahsa Akrami ,&nbsp;Marcin Wojciech Sliwa ,&nbsp;Maja Karoline Rynning","doi":"10.1016/j.urbmob.2024.100077","DOIUrl":"https://doi.org/10.1016/j.urbmob.2024.100077","url":null,"abstract":"<div><p>The 15-minute city theory has recently become a popular paradigm in urban development. It claims that everyone should have access to the essential services, facilities and green spaces within a 15-minute walk. This article tests this concept in Oslo, Norway using a mixed-methods approach, based on a Geographical Information Systems (GIS) analysis of accessibility, review of relevant plans, interviews with planners and a case study of the Hovinbyen area. The objective was to find out to what extent Oslo is a 15-minute city, and discuss how this concept can be integrated in urban planning strategies more generally. The study shows that the central part of Oslo is already a 15-minute city, and that several areas are transforming in this direction. However, many suburban neighborhoods have low accessibility scores, and, according to the plans, will likely not change much in the future. This article argues that the 15-minute city concept cannot serve as the main development strategy, but such an analysis can be useful as a diagnostic study or to assist planning in rapidly changing areas or city extensions. The concept can therefore be considered as a flexible tool to support other planning strategies that share the same goals and ambitions. Any interventions that such accessibility analyses suggest should be contextualized and developed in combination with other qualitative assessments and in partnership with local communities.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"5 ","pages":"Article 100077"},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000074/pdfft?md5=2a81a321b01a2e8977d7ef58a8731e7f&pid=1-s2.0-S2667091724000074-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140308886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By examining the extent to which pedestrianisation may contribute to the creation of “winner” and “loser” streets in the same neighbourhood, the study complements previous literature in this area, which has mainly focused on assessing spatial equity between different neighbourhoods. The study is based on 11 qualitative interviews and a focus group with key stakeholders involved in the design and implementation of the superblocks plan. In the findings, I review the main spatial equity implications of the new green axes, identify trade-offs between equity and viability of implementation, and examine the measures taken by the municipality to minimise inequities between streets. My findings show that the spatial equity implications of pedestrianisation are complex and multidimensional. Although pedestrianisation may strengthen inequities between streets, the gains experienced by pedestrianised streets are not limited to residents living on those streets. However, pedestrianised streets risk becoming a victim of their success, experiencing significant public space and gentrification pressures. Transforming more streets simultaneously might contribute to spread these pressures more evenly, but risks creating greater political and social backlash.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"5 ","pages":"Article 100074"},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000049/pdfft?md5=f11e00e31edc2d5e673b4e90dc820c57&pid=1-s2.0-S2667091724000049-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140179574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This investigation gathers 4,970 Twitter responses to the question, ‘Is 23 minutes walking distance?’, and uses a mixed-methods approach to investigate walking thresholds with four main goals. First, a descriptive overview of responses and analysis of public discussion identifies attitudes, with 63.3% of respondents agreeing that 23 minutes is acceptable. Second, a thematic analysis identifies 27 themes important to walking thresholds within four categories: external (31.4%), circumstantial (32.8%), accessibility (22.0%), and subjective (13.8%). Third, a sentiment analysis using Azure Machine Learning statistically determines and categorizes opinions about a 23-minute walking threshold, confirming agreement (mean=0.547). Fourth, ANOVA mean-comparison tests determine the sentiment with each theme, with 18 themes negatively and one theme positively associated with a 23-minute walking threshold. Results indicate that while 23 minutes is theoretically a generally agreeable walking distance, a number of factors significantly reduce this threshold making it less agreeable in practice. Understanding the factors influencing walking thresholds, or the point at which another mode is considered or the trip is not taken, is crucial for a better understanding of travel behavior and, in turn, more equitable urban planning, transportation management, and infrastructure development.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"5 ","pages":"Article 100073"},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000037/pdfft?md5=4952b09899d25744aba4bacba0872c8c&pid=1-s2.0-S2667091724000037-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139992994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This commentary nevertheless explores four recurring critiques of (street) experimentation and proposes how looking more deeply at them might empower, rather than weaken, such initiatives. Engaging with these critiques is therefore not meant as a renewed criticism, per se, of (street) experiments. Rather, it recognizes that getting into the technicalities and specific designs and elements that might improve street experiments and their capacity to impact change advances knowledge in the field, but argues that advocates must not forget some key baseline critiques they might face - and be ready to either defend or amend their choices accordingly. This commentary is a call to be more creative and less conforming, and to come back again to the deeper motivations for what (street) experiments are meant to do; or develop a better understanding of those motivations. This commentary also leaves open questions that will require further research. Disconfirming some of the hypotheses emerging here would be no less interesting than confirming them.

The competing roles and practical uses that pedestrianized streets must fulfil partially determined their fate. However, the <em>trajectories</em> these cases followed also differ due to the contextual planning approach and decision-making process.
