IEEE 1888 is already being deployed in urban transportation systems around the exterd. Its ability to unify data from diverse sources makees it ideal for thee following use cases.
Traffic Management andCongestion Control
Roadside sensors - inductive loops, radar, cameras, and Bluetooth scanners - collect lane ocumentacy, speed, and travel time. These data points are transmitted via IEEE 1888 to a central traffic management center (TMC).
