Urban areas around the globe are embracing the newest developments in modern technology by becoming smart cities. These cities integrate sensors and actuators and link them together to collect data. We were intrigued when we first learned about smart cities, so we began doing our own research to discover additional details and we wanted to share this information with others. When you read these articles you'll learn how smart city technology uses the data that's gathered to monitor energy usage in homes and buildings to analyze their energy efficiency. You'll also find out about smart transportation, which entails installing cameras in traffic lights to monitor the flow of traffic. We hope that when you read these and other articles on this site you'll gain a better understanding of smart city technology.
