Before revision:  For system efficiencyand sustainability, bus supply adjustment can increase the bus average load and reduce total PCE , while the AV supply adjustment shows the oppositeeffect. For policy implications, the paper suggests that PT should be allowed to optimize its supply strategies under specific operation goal constraints, and AV operation should be regulated to relieve its externality on the system, including limiting the number of licenses, operation time, and service areas, which makes AV operate like a complementary mode to PT .
