Milton Keynes is one of the UK’s ‘new towns’, built in the 1960s with a target population of 250,000. Estimates for the next decade expect it to reach 350,000, and the local authority has to make the expanding city work. Enter AI and the Internet of Things (IoT). Using sensors and monitors, bins can be emptied only when completely full, lights turned on only when there is footfall in that area and traffic lights adjusted to prevailing traffic conditions, making the town fitter, leaner and with great abs. All software used is open source, cutting down on implementation costs.
