| Abstract | This paper focuses on the control of large-scale congested urban networks with intricate traffic dynamics. We consider networks with the following properties. They are highly and uniformly congested. Congestion arises in all directions of travel. Hence, congestion patterns do not reveal a clear hierarchy or priority between intersections or between links. The links are configured in a grid topology. This allows for intricate traveler behavior, such as high-dimensional route choice alternatives. This makes the prediction of how traffic (i.e., travelers) will respond to changes in the network supply a greater challenge. Most links of the network are short links, which are prone to the occurrence of spillbacks, also known as spillovers, and contribute to a rapid spatial propagation of congestion. The networks have multi-modal traffic (e.g., cars, transit). Additionally, the case studies of this paper consider networks with heavy pedestrian traffic. Hence, the design of control strategies for vehicular traffic (e.g., traffic signals) is constrained by non-negligible pedestrian crossing times, and this at every intersection. For such networks, the main shortcoming of existing signal control methods is the lack of a detailed modeling, or estimation, of between-link interactions, which enables an accurate description of the spatial propagation of congestion. Most signal control strategies do not account for betweenlink (i.e., between-queue) interactions. They are based on the use of vertical queues, also called Massachusetts Institute of Technology, Cambridge, MA, USA School of Highway, Chang’an University, Xi’an, China New York City Department of Transportation, New York, NY, USA New York City Department of Transportation, New York, NY, USA New York City Department of Transportation, New York, NY, USA |
