Smart Cities and Communities Act of 2017 This bill establishes programs for the implementation and use of smart technologies and systems in communities of various sizes. A “smart city or community” is one in which innovative, advanced, and trustworthy information, communication, and energy technologies are applied to: (1) improve the health and quality of life of residents; (2) increase efficiency of operations and services; (3) promote economic growth; and (4) improve safety, security, sustainability, resiliency, livability, and work life. The Department of Commerce shall establish a regional demonstration grant program focused on facilitating adoption, and allowing measurement and validation of performance, of advanced smart city or community technologies and systems. Commerce shall also convene a working group to develop tools for evaluating the cybersecurity of smart city or community technologies. The Department of Labor shall establish a pilot program to furnish competitive grants for technology-based job training and education programs that provide industry-recognized credentials. The bill requires strong federal encouragement and support for private sector-led standards development activities. The bill requires the establishment of a strategic international smart cities and communities trade program that includes trade missions to promote and assist smart-community activities, as by leveraging expertise in infrastructure development.
