An open source research framework for IoT-capable smart traffic lights

Recent technological advances are completely reshaping the way we build our cities, and the way we enjoy them. Future smart cities will employ a number of smart sensors, which cooperatively work to deliver advanced services that improve security and quality of life. The capability of deploying and testing such technologies directly on-the-field is paramount to research, however comes with a significant effort in terms of time and price. For this reason, we introduce an opensource design framework for highly-connected smart sensors, and we implemented it in an advanced controller for traffic light, providing a single component to support researchers and engineers from the earliest stages of development in laboratories till on-the-field research and testing.
