Influences of Single-Lane Automatic Driving Systems on Traffic Efficiency and CO<sub>2</sub> Emissions on China’s Motorways

There are big differences between the driving behaviors of intelligent connected vehicles (ICVs) and traditional human-driven vehicles (HVs). ICVs will be mixed with HVs on roads for a long time in the future. Different intelligent functions and different driving styles will affect the condition of...
