Sammendrag
The content discusses a proposed control scheme for multi-gated perimeter traffic flow control in monocentric cities. It introduces practical flow allocation policies and presents a study on a protected network area of San Francisco, CA. The analysis focuses on optimizing input flows, managing queues, and maximizing system throughput.
Efficiency and equity are key considerations in the proposed scheme, which aims to distribute input flows optimally while maintaining desired vehicle accumulation levels. The study showcases the effectiveness of the approach in managing excessive queues outside the protected network.
The article also delves into macroscopic modeling of urban road networks, highlighting the relationship between average network flow and traffic density. Various strategies for traffic management are discussed, including congestion pricing schemes and perimeter flow control policies.
Overall, the content provides insights into innovative approaches for traffic flow control in urban areas, emphasizing efficiency and equity considerations.
