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, the impact of CAVs on macroscopic fundamental diagram (MFD) is analyzed with microscopic traffic simulations, and the sensitivity analysis of market penetration rates of CA V s and network configurations is conducted. The analysis shows that one-way grid networks offer the most accessible and resilient environment during various phases of CA V introduction. Moreover, the introduction of CA V s not only improves the aggregated network performance but also improves the accessibility (trip completion rate) of regular HDVs.
