Smart cities use technology, data, and analytics to improve cities: to protect people, conserve resources, improve mobility, promote public health, and more. Researchers, companies, non-profits organizations, and city governments are using computing, communications, and sensor technologies to design, develop, and deploy data-driven, analytics-augmented systems, services, and infrastructure. These smart city approaches will improve all aspects of city life and operations, from transportation and public safety to environmental quality and sustainability, from healthcare and housing to education and economic development. Come meet with practitioners and potential participants who want to make the world better for all, city by city.
