Recommendations may include predefined incident response plans and regional surface street and freeway control strategies that correct network imbalances.

At Pittsburgh in the United States the Robotics Institute at the Carnegie Mellon University has perfected a high-performance system crammed full of artificial intelligence devices for the flow control of urban traffic (Surtrac, Mobility Prize).

Its aim is to optimise the regulation of urban traffic, to coordinate different modes of transport and, finally, to provide a high standard of information for all modes of transport in real time.
