Influences of Single-Lane Automatic Driving Systems on Traffic Efficiency and CO2 Emissions on China’s Motorways

There are big differences between the driving behaviors of intelligent connected vehicles (ICVs) and traditional human-driven (HVs). ICVs will be mixed with HVs on roads for a long time in future. Different functions different styles affect condition traffic flow, thereby changing efficiency emissions. In this paper, we focus China’s expressways secondary motorways, impacts ‘single-lane automatic system’ (SLADS) delay, road capacity carbon dioxide (CO2) emissions were studied under ICV penetration rates. Driving regarded as important factors scenario analysis. We found that higher volume input, SLADS has an optimizing effect CO2 generally, which more significant rate increases. Additionally, enhancing aggressiveness behavior appropriately is effective way to amplify benefits SLADS.
