Abstract

Abstract. The population of cities is increasing rapidly day by day, and it is predicted that this increase will continue in the following years. Accordingly, population growth creates a significant pressure in many different domains of cities such as infrastructure, traffic, energy, and environment. Smart cities come forward as a useful option to struggle with the pressure on cities caused by overwhelming population growth and to make cities liveable and sustainable. Smart city approach creates gains in the fields of sustainable development, competitiveness and environmental sustainability with its ability to transform information into economic, social and environmental benefits. However, smart city services and applications are mostly designed as independent and unrelated units so this approach causes isolated and heterogeneous data and technology islands. As the result, data flow problem occurs between vertical applications and service suppliers, and this interoperability problem causes emergence of independent silos in smart cities. Such silos hinders data integration, prevent citizens and public administrations benefit fully from smart cities, and cause vendor lock-in. In order to use the full potential of smart city approach, it’s vital to secure interoperability systems and applications of smart cities. In this study, interoperability terms and their necessity for smart city ecosystem will be addressed. Afterwards, Smart City Interoperability Model’s (SCIM) contributions to semantic, technical and operational interoperability will be discussed.

Highlights

  • Population of cities is increasing unprecedentedly day by day

  • 2020-2023 Smart Cities Strategy and Action Plan of Turkey (SAP) was published in December 2019 to ensure interoperability by bringing a holistic perspective to smart city policies at the national level, to prioritize investments in line with the determined policies, and to ensure that the investments are implemented with the right projects and activities (Bayar et al, 2020)

  • With Smart City Interoperability Model (SCIM), existing frameworks and standards have been proposed that will contribute to the work of all smart city stakeholders in terms of semantic, technical and organizational aspects, rather than introducing new standards and models

Summary

INTRODUCTION

Population of cities is increasing unprecedentedly day by day. In 1950, %30 of the world’s total population was residing in cities and this number increased up to %54 in 2014 (United Nations Department of Economic and Social Affairs, 2014). Smart city approach creates gains in the fields of sustainable development, competitiveness and environmental sustainability with its ability to transform information into economic, social and environmental benefits In this context, ICT is the key-enabler for implementing innovative solutions, services and applications to make cities “smart” (Petrolo et al, 2015). Data flow problem occurs between vertical applications and service suppliers, and this interoperability problem causes emergence of independent silos in smart cities (Brutti et al, 2019). Such silos use different communication technologies, architectures and standards as well
