Artificial intelligence and other technologies promise to improve traffic systems and reduce the aggravation of commuters. Originating in Australia, the Sydney Coordinated Adaptive Traffic System uses sensors at intersections to respond to traffic conditions in real time, with signal-timing decisions made via a control box, while system-wide decisions are generated by a remote computer. Siemens Mobility's Split Cycle Offset Optimization Technique quantifies traffic at intersections and incrementally optimizes real-time signal timing. Israeli technology company NoTraffic has created what it calls the world's first autonomous traffic management platforms, currently used in Phoenix, AZ, and several California cities; the platforms, which make use of radar and video, allow municipalities to create policies and control traffic flow both at the grid level and for each intersection where the technology is deployed. ...
