Eco-lane is an important means to implement Eco-driving behavior and reduce vehicle energy consumption emission. Cooperative vehicle infrastructure Connected technology provides the possibility to further improve energy saving and emission reduction benefits of Eco-lane. Based on the Cooperative vehicle infrastructure driving simulator experiment platform, 40 subjects were selected to carry out the comparative test of vehicle energy consumption emissions under three conditions of expressway: ordinary road, Eco-lane and vehicle-mounted human-machine interaction system (HMI) based Eco-lane. The results showed that compared with ordinary road sections, the Eco-lane has a significant energy saving and emission reduction potential, which can reach 24.02-59.04% and 24.15% respectively. Under the condition of cooperative vehicle infrastructure, the Eco-lane has the highest energy saving and emission reduction potential, with the emission reduction potential of 24.46%-59.72% and energy saving potential of 24.61%. Therefore, vehicle energy consumption and emission can be significantly reduced by setting Eco-lanes in the basic sections of expressway under the condition of cooperative vehicle infrastructure.
