Risk-Aware Active Traffic Management
Abstract:
Active Traffic Management (ATM) is an approach to the management of vehicular traffic, based on measurement of prevailing traffic conditions and predicted future scenarios, in order to reduce the risk of major degradation in road network performance. ATM is a continuous process of (1) obtaining and analyzing traffic measurement data; (2) simulating various future scenarios and control strategies; (3) implementing the most promising control strategies in the field; and (4) maintaining a real time decision support system that filters current traffic measurements to predict the traffic state in the near future, and to suggest the good control strategies for the predicted situation. ATM relies on a fast and trusted traffic simulator for the rapid quantitative assessment of a large number of control strategies under various scenarios, in a matter of minutes.
