Summary This paper investigates a strategic signal control, which anticipates travelers' route choice response and determines signal timings to optimize network-wide objectives. In general traffic assignment models are used for anticipating this route choice response. However, model-reality mismatch usually brings suboptimal solutions to the real system. A repeated anticipatory control resolves the suboptimality and addresses the modeling error by learning from information on model bias. This paper extends the repeated control approach and focuses on the estimation of flow sensitivity as well as its influence on control, which is a crucial issue in implementation of model bias correction. The main objective of this paper is first to analyze the estimation error in the real flow derivative that is estimated from noisy measurements. A dual control method is then presented, improving both optimization objective function and derivative estimation during the control process. The proposed dual algorithm is tested on a simple network as well as on a midsize network. Numerical examples confirm the reliable performance of the new reality-tracking control strategy and its ability to identify (local) optimal solutions on real traffic networks.
