Model-based traffic control [PDF]
Artificial Intelligence in Engineering, 1992 Abstract Urban traffic control is a difficult problem because of the complex interdependence of control decisions. Known techniques for achieving global control are based on parameter optimization techniques or heuristic expert systems. Optimization fails in severely congested traffic situations which require a change in global strategy.
