Smart city deals with the problems of rapid urbanization and population growth by optimal utilization of all available resources. There are other driving factors such as clean energy programmes, a low carbon economy and distributed energy resources that are included in a smart city concept. Therefore, in this article, the authors proposed a clean energy generating model by utilizing the kinetic energy of vehicles over a speed breaker. The article focused on the design, modelling, and simulation of an electromechanical system for generating electrical power from the kinetic energy of vehicles passing over speed breakers. To facilitate simulation, a model of the electromechanical system is developed in MATLAB/Simulink. Further, MULTISIM 14 software is utilized for power electronic device modelling and simulation. Simulation results for power generation are obtained considering four units of rotational induction generators and two units of translational induction generators.

The European Union is in the process of updating its energy policy and legislative framework under the motto “Clean Energy for All Europeans”. This will facilitate the low carbon energy transition, make it fit for the 21st century, and delivering the EU’s Paris Agreement commitments. Besides expected climate-energy benefits, the EU narrative is introducing new elements to persuade citizens and stakeholders to change their perspective, shifting the general perception from mitigation costs to development opportunities. For example, impact assessment of the new directives estimated that they would generate 900,000 jobs and an increase of up to 1% in EU GDP over the next decade. However, this is just one among several multiple benefits that could be gained thanks to the smart energy transition of cities and neighborhoods (e.g. increased value of refurbished properties, improved health and well-being, enhanced social cohesion, etc.) Starting from this premise, the ongoing research will analyses 12 ongoing EU smart cities and communities projects started between 2014 and 2017, in order to investigate their capability in using the multiple benefits as an effective communication tool, or even including them among the key performance indicators to be used in the assessment phase. In that respect, the Positive energy district concept that permeates the smart city approach of latest calls for funding provides, even more, an interesting nexus and testbed opportunity for EU ambitions. However, ongoing and future projects need to be understood not only as marketing devices for new energy efficient technologies but powerful tools requiring a radical change in management and planning of cities and urban life. In this way, positive energy districts including good habits and behaviors of urban citizens will provide equitable solutions and clear benefits for all.

Without decarbonizing cities energy and climate objectives cannot be achieved as cities account for approximately two thirds of energy consumption and emissions. This goal of decarbonizing cities has to be facilitated by promoting net-zero/positive energy buildings and districts and replicating them, driving cities towards sustainability goals. Many projects in smart cities demonstrate novel and groundbreaking low-carbon solutions in demonstration and lighthouse projects. However, as the historical, geographic, political, social and economic context of urban areas vary greatly, it is not always easy to repeat the solution in another city or even district. It is therefore important to look for the opportunities to scale up or repeat successful pilots. The purpose of this paper is to explore common trends in technologies and replication strategies for positive energy buildings or districts in smart city projects, based on the practical experience from a case study in Leipzig—one of the lighthouse cities in the project SPARCS. One of the key findings the paper has proven is the necessity of a profound replication modelling to deepen the understanding of upscaling processes. Three models analyzed in this article are able to provide a multidimensional representation of the solution to be replicated.

Cities are futures' crucial elements, playing an important role in economics, social and environmental. As closer to individuals, cities face some challenges in terms of problems caused through the rapid urbanization process. Hence, governments and public agencies at all levels should use smart techniques including technology for sustainable development, better quality of life for citizens, and finally, an efficient use of scarce public resources. In this sense, Turkey plans to apply a smart city concept in Turkish cities as worldwide and published 2020-2023 National Smart Cities Strategy and Action Plan document with four strategic goals, nine targets, and 40 actions. This chapter aims to reveal the institutional, fiscal, and social challenges on smart governance, which is the most important dimension of smart city, for Turkey. In this respect, there are some challenges on smart governance in Turkey in terms of legislation, institutional, transparency and accountability, participation, e-democracy, and citizens.

More countries and regions are joining the bandwagon of smart city construction, which is an important strategy and innovative urban governance concept to solve the problem of rapid urbanization. This paper examines whether smart city innovation is able to ameliorate the traffic congestion faced by a large number of cities. Using panel data for 187 prefecture-level cities in China from 2008 to 2017, this paper tests the effect of implementation of a smart city on urban traffic congestion with the difference-in-difference method. The results show that, firstly, the construction of smart cities have significantly reduced the degree of urban traffic congestion and improved the quality and capacity of public transport. Secondly, information technology and urban innovation are the main mechanisms for smart city implementation to improve urban traffic problems. Thirdly, the improvement effect of smart city implementation on traffic management shows an increasing marginal effect over time. By overcoming the estimation bias in previous studies, this study accurately analyzes the positive role and dynamic effect of smart city construction on traffic improvement. It augments the literature of program evaluation and assessment of smart city implementation. By examining how to improve traffic congestion, it offers some insights that could inspire governments to build smarter cities with better traffic.

Cities constitute three quarters of global energy consumption and the built environment is responsible for significant use of final energy (62%) and greenhouse gas emissions (55%). Energy has now become a strategic issue for local authorities (LAs) and can offer savings when budget cuts have threatened the provision of core services. Progressive LAs are exploring energy savings and carbon reduction opportunities as part of the sustainable and smart city agenda. This paper explores the role of citizens in smart city development as “buildings don’t use energy: people do”. Citizens have the potential to shape transitions towards smart and sustainable futures. This paper contributes to the growing evidence base of citizen engagement in low carbon smart cities by presenting novel insights and practical lessons on how citizen engagement can help in smart city development through co-creation with a focus on energy in the built environment. A case study of Nottingham in the UK, a leading smart city, is analysed using Arnstein’s Ladder of Citizen Participation. Nottingham City Council (NCC) has pledged to keep “citizens at the heart” of its plans. This paper discusses learnings from two EU funded Horizon 2020 projects, REMOURBAN (REgeneration MOdel for accelerating the smart URBAN transformation) and eTEACHER, both of which aimed to empower citizens to reduce energy consumption and co-create smart solutions. Although these two projects are diverse in approaches and contexts, what unites them is a focus on citizen engagement, both face to face and digital. REMOURBAN has seen a “whole house” approach to retrofit in vulnerable communities to improve liveability through energy efficiency. User interaction and co-creation in eTEACHER has provided specifications for technical design of an energy saving App for buildings. eTEACHER findings reflect users’ energy needs, understanding of control interfaces, motivations for change and own creative ideas. Citizens were made co-creators in eTEACHER from the beginning through regular communication. In REMOURBAN, citizens had a role in the procurement and bidding process to influence retrofit project proposals. Findings can help LAs to engage demographically diverse citizens across a variety of buildings and communities for low carbon smart city development.

With the ongoing rapid urbanization of city regions and the growing need for (cost-)effective healthcare provision, governments need to address urban challenges with smart city interventions. In this context, impact assessment plays a key role in the decision-making process of assessing cost-effectiveness of Internet of Things–based health service applications in cities, as it identifies the interventions that can obtain the best results for citizens' health and well-being. We present a new methodology to evaluate smart city projects and interventions through the MAFEIP tool, a recent online tool for cost-effectiveness analysis that has been used extensively to test information and communications technology solutions for healthy aging. Resting on the principles of Markov models, the purpose of the MAFEIP tool is to estimate the outcomes of a large variety of social and technological innovations, by providing an early assessment of the likelihood of achieving anticipated impacts through interventions of choice. Thus, the analytical model suggested in this article provides smart city projects with an evidence-based assessment to improve their efficiency and effectivity, by comparing the costs and the efforts invested, with the corresponding results.

Resource Needs

Rapid urbanization has brought about an influx of people to cities, tipping the scale between urban and rural living. Population predictions estimate that 64% of the global population will reside in cities by 2050. To meet the growing resource needs, improve management, reduce complexities, and eliminate unnecessary costs while enhancing the quality of life of citizens, cities are increasingly exploring open innovation frameworks and smart city initiatives that target priority areas including transportation, sustainability, and security. The size and heterogeneity of urban centers impede progress of technological innovations for smart cities. We propose a Smart Stadium as a living laboratory to balance both size and heterogeneity so that smart city solutions and Internet of Things (IoT) technologies may be deployed and tested within an environment small enough to practically trial but large and diverse enough to evaluate scalability and efficacy. The Smart Stadium for Smart Living initiative brings together multiple institutions and partners including Arizona State University (ASU), Dublin City University (DCU), Intel Corporation, and Gaelic Athletic Association (GAA), to turn ASU’s Sun Devil Stadium and Ireland’s Croke Park Stadium into twinned smart stadia to investigate IoT and smart city technologies and applications.

This paper studies the impact of the implementation of smart city policy (SCP) on the development of low-carbon economy (LCE) in China. For this purpose, we developed a nonconvex meta-frontier data envelopment analysis (DEA) approach to measure LCE and used the differences-in-difference (DID) analysis method in the econometric model to empirically analyze the impact of SCP on LCE, using the dataset of 230 cities from 2005 to 2018. The results show that the implementation of SCP can significantly improve the LCE of cities, and the dynamic effect test presents that the promotion of smart cities to low-carbon economy increases with time. In addition, SCP promotes the development of LCE by optimizing government functions and improving the efficiency of governance and the degree of implementation openness. But there is heterogeneity between different cities as follows: the implementation of SCP has a more significant effect on the promotion of LCE in central and western regions in China and large-scale cities and cities without strict environmental protection planning. Finally, the robustness test verifies the reliability of the experimental data again and puts forward conclusions and policy recommendations.

Cities in the Global South face rapid urbanization challenges and often suffer an acute lack of infrastructure and governance capacities. Smart Cities Mission, in India, launched in 2015, aims to offer a novel approach for urban renewal of 100 cities following an area-based development approach, where the use of ICT and digital technologies is particularly emphasized. This article presents a critical review of the design and implementation framework of this new urban renewal program across selected case-study cities. The article examines the claims of the so-called “smart cities” against actual urban transformation on-ground and evaluates how “inclusive” and “sustainable” these developments are. We quantify the scale and coverage of the smart city urban renewal projects in the cities to highlight who the program includes and excludes. The article also presents a statistical analysis of the sectoral focus and budgetary allocations of the projects under the Smart Cities Mission to find an inherent bias in these smart city initiatives in terms of which types of development they promote and the ones it ignores. The findings indicate that a predominant emphasis on digital urban renewal of selected precincts and enclaves, branded as “smart cities,” leads to deepening social polarization and gentrification. The article offers crucial urban planning lessons for designing ICT-driven urban renewal projects, while addressing critical questions around inclusion and sustainability in smart city ventures.

A smart city is rising as an approach and strategy to reduce the troubles produced by rapid urbanization and the growth of urban population. Although, cities continue to develop and purify their social, economic and environmental goals along with the strategies to achieve them, this phenomenon has been discussed by little research yet. However, due to the requiring immediate action or attention for practical application of the principles of smart cities, city authorities, stakeholders and local communities need to know the current reality of their city and where development is being attained in their systems. Therefore, constructing a framework for smart cities assessment will help share or exchange the newcomer strong and weak points, and emphasize where actual development is taking place and update a plan for future developments. Moreover, this assessment is able to assist cities prioritizes actions. This paper developed a guiding assessment framework for smart cites that will help the creating, carefully choosing and priorities of crucial indicators. These indicators can then show the way to the smart cites performance assessment and monitoring. Drawing on the investigation of an extensive and wide collection of literature from a variety of disciplinary areas and based on the conceptual literature on smart cities, in addition to interviews this study identify a good tool to help recognizing of virtual achievement of smart city. Furthermore, it is significant to be taken into consideration in assessing smart city smartness level.
