On-ramp merging strategy for connected and automated vehicles based on complete information static game
TL;DR: This paper focuses on the scenario of CAVs on-ramp merging and proposes a centralized control method based on a complete information static game whereby the mixed-strategy Nash equilibrium is calculated for an individual vehicle to select its strategy.
