Analysis of carbon emission distribution characteristics of the bus stop area in the net-connected environment

The bus stop area is an important area for vehicles to generate traffic emissions. In order to study the characteristics of vehicle emissions in the bus stop area under the net-connected environment, a mixed traffic flow simulation environment is constructed based on the analysis of the travel behavior of manual driving vehicles, ACC vehicles and CACC vehicles, and the influence of different factors on vehicle carbon emissions in the bus stop area is analyzed by using the car-following model and lane-changing model. Firstly, the full speed difference model, ACC model and CACC model are selected as the car-following models for manual driving vehicles and net-connected vehicles respectively, and the lane-changing model is constructed using the discretionary lane change model and the mandatorylane change model; the VT-Micro model is selected as the carbon emission calculation model; finally, MATLAB is used for numerical simulation to simulate and analyze the traffic emission distribution characteristics of the bus stop area under the net-connected environment. The results show that the carbon emissions in the upstream of the bus stop increase as the proportion of bus increases, the traffic volume increases and the proportion of net-connected vehicle decreases. The carbon emission hotspot was identified as the upstream of the stop near the inner lane. This result can provide a basis for carbon emission management at bus stops in the future.
