“…The concept of the "15-Minute City", in which everything that residents may need (stores, restaurants, etc.) is accessible by walking or cycling within 15 minutes, is also supportive of compact urban development and has been discussed in relation to a net-zero urban future [96]. These can all contribute to a fair turn-sharing approach to sustainability [31].…”

Dispersed low-density development–“urban sprawl”–has many detrimental environmental, economic, and social consequences. Sprawl leads to higher greenhouse-gas emissions and poses an increasing threat to the long-term availability of many vital ecosystem services. Therefore, urban sprawl is in stark contradiction to the principles of sustainable land use and to the need for a sustainability transformation. This study presents the degree of urban sprawl on the planet at multiple spatial scales (continents, UN regions, countries, subnational units, and a regular grid) for the period 1990–2014. Urban sprawl increased by 95% in 24 years, almost 4% per year, with built-up areas growing by almost 28 km2 per day, or 1.16 km2 per hour. The results demonstrate that Europe has been the most sprawled and also the most rapidly sprawling continent, by 51% since 1990. At the scale of UN regions, the highest relative increases in urban sprawl were observed in East Asia, Western Africa, and Southeast Asia. Urban sprawl per capita has been highest in Oceania and North America, exhibiting a minor decline since 1990, while it has been increasing rapidly in Europe, by almost 47% since 1990. The study revealed a strong relationship between urban sprawl and the level of human development as measured by the Human Development Index (HDI). The results suggest that it will be important for a more sustainable future to find a better balance between a high quality of life and using land more sparingly. There is an urgent need to stop urban sprawl, since current regulations and measures in developed countries are apparently not effective at limiting it. Monitoring urban sprawl can serve to guide policy development such as the implementation of targets and limits and to evaluate the effectiveness of urban growth management strategies at mitigating urban sprawl.

“…All activities are carried out in accordance with the idea of sustainable because sustainable transport is considered one of the main aspects that characterize smart cities [4]. Among the ideas promoting sustainable transport in cities, it can be distinguished, for example, that the '15-min city' concept, which aims to provide sustainable walking access to central services and/or places, helps to reduce the phenomenon of commuting and thus reducing negative externalities such as pollution of air [5,6]. Among other solutions closely related to the '15-min city', Balletto et al emphasize that it is particularly important for smart cities to ensure an appropriate level of accessibility and walkability for residents [5].…”

Visual Communication in Shared Mobility Systems as an Opportunity for Recognition and Competitiveness in Smart Cities

Due to the intensive development of urbanization and digitization, the number of smart cities in the world is growing. Along with their exposure, more and more challenges are facing the service providers of the various types of systems offered in their area. These types of services include shared mobility systems that, as an alternative to transport by own vehicle, are becoming one of the leading promoted forms of mobility. Because of the prioritization of shared mobility solutions, more and more operators appear on the smart city markets, which is associated with many challenges related to the increased competition among service providers. One of the challenges is the appropriate visibility of the brand and vehicles in urban transport systems. This aspect, despite its high applicability, constitutes a research gap among world studies. Aiming to fill this gap, this article was dedicated to the issues of perception of visual communication by operators of shared mobility services. As part of the research, an expert study was conducted among representatives of shared mobility services operating in Poland. The expert survey was conducted with the Computer-Assisted Web Interview (CAWI) technique. The results of the research show that visual communication is not used quite correctly by operators. Although operators use single visual communication practices, overall consistency is lacking, which would add value to the brand. This article supports operators looking to expand their shared mobility services. What is more, it is also a response to the research gap regarding visual communication and its perception from the point of view of smart cities.

“…The '15minute city' model was developed by Moreno ( 2016) but became more popular on the time of COVID-19 pandemic. The approach is based on the idea that certain facilities of daily activity are positioned in easily accessible distances (Allam et al, 2022).…”

Evaluating the pedestrian accessibility to public services using open-source geospatial data and QGIS software

et al. 2022

This study brings a rapid method to utilize the available open-source geospatial data in assessing the pedestrian accessibility to key public services/facilities. At this stage, we are testing the method in the case of Tirana, the capital city of Albania. Yet, the method is reproducible to other metropolitan areas around the world. Open street map (OSM) data and reference layers from Albanian National authority for geospatial information (ASIG geoportal) have been used as the raw material of the study. While the geospatial visualization, refinement, and analysis rely on the usage of QGIS software and the related plugins. QNEAT is the plugin that was used to generate the isochrones which indicate the spatial coverage of a certain service referring to the existing urban transportation/circulation network. The plugin enables the definition of different distance ranges. Our results show that certain public services serve to various amounts of the building stock at a gradient of walking distances. For example, more than 25% of the existing building stock has pedestrian access to caffes and pharmacies within a walking distance of 250 m. The same services serve to almost 90% of the same building stock within 1 km walking distance. However, services like banks are accessible only by 12.6% of the existing buildings within a walking distance of 250 m, and 67% at 1 km walking distance. The accuracy of the available geospatial data resulted to be vital for the reliability of the results. We conclude by highlighting the importance and utility of GIS-based methods of urban analysis in the processes of planning new public services in the city.
