This year, IDC projects the focus of smart initiatives will be intelligent transportation, data-driven public safety, and resilient energy and infrastructure. The two largest use cases, when measured by worldwide spending, are intelligent traffic and transit and fixed visual surveillance, followed by smart outdoor lighting and environmental monitoring.
