Analysis on the Impact of Autonomous Vehicle Mixture on Traffic Flow around Parking Lot Entrance

Abstract

When there are no pedestrians around at the entrance and exit of a parking lot, most vehicles do not come to a complete stop. However, if autonomous vehicles become widespread, the number of vehicles adhering to traffic regulations and stopping at parking lot entrances could increase, potentially affecting the rate of stopping at these entrances and exits and influencing the smoothness of traffic flow in the surrounding area. Therefore, this study used micro-traffic simulation to analyze the impact of stopping at parking lot entrances in a mixed scenario with autonomous vehicles on the surrounding traffic flow. The results showed that as the proportion of autonomous vehicles in the mix increased, there was a tendency for average delay time to increase. However, on multi-lane roads, following vehicles often passed through the second lane due to entering vehicles, which mitigated significant delays. On the other hand, an increase in traffic volume and pedestrian traffic volume led to an increase in average delay time.
