Dispersed low-density development–“urban sprawl”–has many detrimental environmental, economic, and social consequences. Sprawl leads to higher greenhouse-gas emissions poses an increasing threat the long-term availability of vital ecosystem services. Therefore, urban sprawl is in stark contradiction principles sustainable land use need for a sustainability transformation.

A composite X-minute city cycling accessibility metric and its role in assessing spatial and socioeconomic inequalities – A case study in Utrecht, the Netherlands

Journal of Urban Mobility, Journal Year: 2022, Volume and Issue: 3, P. 100043 - 100043

Published: Dec. 28, 2022

The 15 min city (or "X-minute city" in general) concept aims to give people access all essential services and daily needs (e.g., healthcare, education, etc.) within X minutes of active transportation, improve transport equity, sustainability, traffic safety. To date, there is a lack methods tools assess what degree cities currently, or after implementing policies, comply with the X-minute concept. This research develop methodology for quantifying through metric (CSx) that was developed based on an accessibility framework tested cycling mode Utrecht region Netherlands as study area. Travel data from mobility panel were analysed determine input characteristics metric, such weight destination types. Standardized gravity-based 2-step floating catchment area (2SFCA) scores types weighted aggregated into composite shows relative city. results analysis show 100% population has at least one 9 min, whereas this number reduces 94% 10 threshold; indicating status cycling-friendly infrastructure. Furthermore, low-income groups do not have lower area, reinforcing notion can be effective solution reduce inequalities. used their way towards becoming city, prioritise neighbourhoods develop, set quantifiable goals, evaluate planning scenarios.

Urban mobility evolution and the 15-minute city model: from holistic to bottom-up approach

Transportation research procedia, Journal Year: 2023, Volume and Issue: 69, P. 544 - 551

Published: Jan. 1, 2023

In recent years, urban planners have mentioned the importance of implementing alternative city models that encourage short trips and neighborhood-scale activities such as 15-minute model. Several studies show improvements in transportation networks citizens to move themselves into their neighborhoods' borders. People seem respond these actions by increasing visits many local places restaurants, bars, sports centres etc. Even though during post-covid era, people decreased significantly movements, it is vital creation friendly for walking inside neighborhoods cities, based on concept Large cities are becoming bigger they offer job opportunities. However, massive peoples' relocation big has a result huge problems. Neighborhoods been downgraded were not ready several services larger populations. The model designed ensure each citizen quick access (15 minutes foot) essential various types. Moreover, implementation demands strengthening promoting sustainable solutions can support daily habitants.

Does the 15-minute City Promote Sustainable Travel? Quantifying the 15-minute City and Assessing its Impact on Individual Motorized Travel, Active Travel, Public Transit Ridership and CO2 Emissions

Networks and Spatial Economics, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Abstract Promoting higher density and implementing mixed land use have long been acknowledged as potentially effective based solutions to transportation problems. However, the policy has leaned toward mobility-based solutions, favouring rapid travel instead of high proximity. This tendency seems now be reversing with increasing popularity 15-minute city. paper assesses effectiveness city in promoting sustainable Lisbon Metropolitan Area. Our research shows that increases non-motorized among its residents by facilitating engagement amenities such supermarkets or green urban areas. Nevertheless, central dense areas are not necessarily cities also contribute towards more travel, being at reducing car due increased public transit use. The impact on CO 2 emissions per household is than since presented a direct alternative transit, while rely an car. Hence, policies combining proximity may eventually maximize benefits emissions.

Urbanization and Drivers for Dual Capital City: Assessment of Urban Planning Principles and Indicators for a ‘15-Minute City’

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 382 - 382

Published: Feb. 12, 2025

Cities, particularly megacities, face significant challenges in transitioning toward sustainability. Many countries have developed dual or multiple capitals for diverse purposes (e.g., political, administrative, economic, touristic, and cultural). Limited research exists on the ‘15-minute city’ (15-MC) concept, regions like Middle East North Africa (MENA region). This study evaluates application of ‘15-MC’ concept globally regionally to derive Urban Planning Principles (UPPs) indicators livability accessibility. Using a theoretical framework supported by site visits quantitative assessments, examines two districts NAC as case studies. Key UPPs proximity services, mixed-use development, public transport, green spaces, community engagement, local economy, sustainability) were evaluated along with walkability scores, bike infrastructure, environmental impact indicators. The results reveal that most services are accessible within 15-minute walk ride. However, essential facilities universities hospitals) exceed this threshold (20–30 min). area per inhabitant (17 m2/capita) meets WHO European recommendations. has clean, transportation 94.26 km cycling lanes. For sustainability indicator, air pollutants (PM10 NO2) slightly guidelines, but SO2 Ozone levels below limits. estimated waste capita (274 kg) is lower than Cario other counties. findings suggest potential fulfill 15-MC through developments, accessibility, sustainable planning. serves future modeling when it fully occupied.
