Multimodal Macroscopic Fundamental Diagram for “Car-Bus” Mixed Traffic Signalized Corridors: Application in City of Barcelona, Spain

This research focuses on the macroscopic modeling of multimodal systems. Specifically, we investigate the existence of macroscopic relations in the Barcelona urban traffic system, including mixed-traffic (bus-car lanes or individual bus-only lanes) and we propose solutions to improve mobility. We study how the throughput of passengers and vehicles depends on the operational characteristics of the system, the level of congestion and the interactions between different modes of transport. Using a microscopic simulator, we investigate the effect of a new high performance bus network (HPB) in the city of Barcelona and we intent to understand macroscopically which is the overall performance of the city as the demand and operational characteristics of each mode changes. Varying different traffic parameters such as traffic demand for private vehicles, frequency and dwell times of buses at each stop are analyzed. We also examine how a congested city center (with a direct application in the city of Barcelona) could reduce its private vehicle demand, by transferring it to public transport and which will be the advantages in term of total delays improvement as a function of demand shift. Our results show that significant benefits can be obtained even in cases frequency of buses (and therefore interactions with vehicles) increase.
