Z. Cong, B. De Schutter, and R. Babuska, "Co-optimization of topology design and parameterized control in a traffic network," Proceedings of the 93rd Annual Meeting of the Transportation Research Board, Washington, DC, 12 pp., Jan. 2014. Paper 14-2951.
In this paper, we introduce a co-optimization approach to jointly optimize the traffic network topology and traffic controllers in a traffic network. Since the network topology design has a long-term goal, while the traffic control is usually based on a minute-to-minute basis traffic situation, we use a so-called parameterized traffic control method to bring them to the same time scale. We apply the proposed co-optimization approach in a simulation-based case study, and compare it with a pure topology design and an iterative optimization method. The results show that our method can improve the interaction between topology design and traffic control design, and result in a better overall performance.
