Germany's Port of Hamburg has installed sensors on light poles that keep an eye on the state of roads and bridges in the port. The sensors know exactly when operators have raised the port's massive lift bridge to allow ships to pass underneath, and thus how to reroute road traffic which cannot cross the bridge. The lighting infrastructure, provided by Philips, also detects any road incidents such as accidents or traffic jams, and alerts port management immediately. And it includes environmental sensors for air quality, as well as motions sensors that turn lights on and off as needed for pedestrians and cyclists in a 'follow me' lighting scheme. The new 'smartROAD' system is a key part of the port's effort to handle more than the 10,000 ships a year it currently loads and unloads and is one of the first deployments of a broader 'internet of everything' smart city collaboration between the city of Hamburg and Cisco.
