Abstract:

Based on the recently proposed concept of an operational urban NFD (Network Fundamental Diagram) and a feedback gating procedure, it is shown that simple, practicable and efficient gating control may be based on a strongly reduced amount of real-time measurements. The urban network of Chania, Greece, is used as a test-bed for the investigations within a realistic microscopic simulation environment. The results indicate that reduced NFDs, obtained with far less measurements than for a complete NFD, exhibit a critical range of traffic states that is virtually equivalent to its counterpart of the complete NFD; and that the provision of accordingly reduced amounts of real-time measurements for feeding the feedback regulator leads to virtually equivalent gating results as in the full measurement case.
