Evaluation of Macroscopic Fundamental Diagram Transition in the Era of Connected and Autonomous Vehicles**Research was supported by Natural Sciences and Engineering Research Council of Canada (NSERC).

The introduction of connected and autonomous vehicles (CAVs) could bring practical solutions to the existing challenges with transportation infrastructures such as accidents and congestion. However, the transition to the era of CAVs would be gradual, and it could be expected that both CA V sand human-driven vehicles (HDVs) would exist in the network for some time, which could change the fundamental properties of urban networks. In this paper, …
