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. This study presents degree on planet at multiple spatial scales (continents, UN regions, countries, subnational units, regular grid) period 1990–2014. Urban increased by 95% 24 years, almost 4% per year, with built-up areas growing 28 km 2 day, or 1.16 hour.

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, Год журнала: 2022, Номер 3, С. 100043 - 100043

Опубликована: Дек. 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, Год журнала: 2023, Номер 69, С. 544 - 551

Опубликована: Янв. 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. This paper focuses literature review different worldwide, starting from Paris where indeed well-suited need cultural change rather than planning. research points out only fact this help grow up socioeconomically but cooperate with authorities participate redesign neighborhood

the pandemic and post-pandemic scenarios pose question of a radical transformation cities based on criteria diversity, density, proximity to foster inclusion, sustainability, participation, quality life. The 15-minute city emerges as robust concept inform adaptation urban environment scenario. combines components proximity, digitalization increase residents' access basic services, favour sustainable modes transportation, transform public spaces into multifunctional places. proposed study focuses dimensions diversity. It develops set indicators derived from configurational analysis evaluate in terms potential actualize concept. selected areas are Terni Matera Italy. addresses three issues: i) defining relevant, reproducible, comparable for measuring imageability at district scale; ii) investigating influence distinct planning concepts, manifested reproduced by configuration spaces, imageability; iii) scale metrics measure levels spatial injustice unequal conditions services. underlines gap services among central compact districts dispersed outer areas. As result, case that is instrumental understanding environment's meet needs populations.

Pedestrian-oriented urban strategies such as the Paris 15-minute City are needed to respond global boiling. Quantitative evaluation of pedestrian-oriented objectives is important for various cities, and in this paper, a walkability system advanced model developed considering characteristics large city. The calculates Seoul. uses Betweenness index weight network analysis. Considering stations with high betweenness traffic essential evaluating metropolis. Our findings study that UNA WES critical transit-oriented, walkable cities. city needs find location mobility hubs or observe last mile. Installing hub station at high-value center functionally important. In city, citizens can walk bike mile busy center. Walkable cities encourage active transport ultimately create more sustainable environmentally friendly transportation systems. This offers valuable insights into pedestrian infrastructure, systems, policies promote green transportation.
