The momentum behind the development of smart cities continues unabated. City leaders around the world are committing to smart city objectives as they attempt to shape the development of their cities to meet social, economic, and environmental challenges. National governments are also encouraging cities to become centers of innovation and drivers of sustainable growth. There are many grand visions for the development of smart cities and even more pilots and demonstration programs. However, there are far fewer large-scale, financially sound deployments of smart solutions to solve core city problems. Today, city leaders and suppliers are recognizing that there needs to be a clearer and faster route to the broader deployment of proven technologies and solutions. The question is how to establish the right business models and deployment strategies to enable this expansion. Meanwhile, city strategies are increasingly emphasizing resilience and climate adaption and focusing on making smart city development relevant to citizens and their daily lives. Smart city trends also include a desire for more data-driven policymaking and operational control and a recognition of the need for standards to help drive smart city programs to the next stage.
