Las Vegas Brings AI to Traffic Lights

So far, 30 intersections have been equipped with cameras and sensors, mostly in the central business district. The city plans to expand that to 80 intersections in the next three months. The pilot project is part of Las Vegas's continuing smart city effort. In such projects, sensors are installed on streetlights, power grids, transit lines and other services to collect data that can be used to deliver services to people more quickly. Las Vegas has used the insights to change signal timing at certain times of day and to put up signage, such as wrong-way signs.
