Nowadays, the status of air pollution and energy consumption in China is becoming increasingly serious. To solve the energy conservation issues in the field of road transport which is a major contributor to energy consumption and air pollution is an imminent problem. The concept of eco-driving appeared in the 1990s in Europe. Compared to traditional methods such as the improvement and adjustment of traffic demand or transportation infrastructure, eco-driving could change the driving behavior fundamentally and thus bring sustained effects of energy saving. However, although many studies show that eco-driving could result in significant energy saving effect for single vehicle, the research of effects of eco-driving under overall traffic environment with the interaction with other normal driving vehicles is not sufficient.Therefore, on the basis of the implementation of eco-driving field tests, this thesis builds a microscopic simulation model based on V1SSIM, and obtains the evaluation indexes from the calibrated simulation model to analyze the effects of eco-driving on the intersection within the context of whole traffic environment. The thesis first synthesizes the literature review of eco-driving test design and qualification method, and designs a single eco-driving vehicle field test which complies the given eco-driving advices. The driving data is collected and processed to evaluate the effects of single eco-driving vehicle preliminary.Secondly, the thesis builds a micro-simulation model based on VISSIM. To make the simulation results more consistent with vehicles’actual operation within the intersection, some of the most relevant parameters are calibrated and the calibration results meet the accuracy requirements. Meanwhile, the thesis also establishes a vehicle energy consumption model based on VSP which link the vehicle’s instantaneous driving data and energy consumption together.For a more comprehensive assessment of the impact of eco-driving behavior, the thesis designs different traffic scenarios of different traffic demands and eco-driving penetrations, and runs the calibrated simulation model to assess the impact of eco-driving behavior within the scope of the intersection from the indicators which are fuel consumption per vehicle and travel time per vehicle. The results show that under different traffic demands scenarios, with the increase of eco-driving penetration, average fuel consumption is reduced, but the change of average travel time is related to the level of traffic demands. Under the low traffic demand scenario, the implement of eco-driving results in the increase of vehicles’residence time within the intersection so that the average fuel consumption increases slightly, while average travel time always increases with the increase of eco-driving penetration. However, to analyze with the indicator of average fuel consumption rate per time unit, eco-driving brings a positive effect of energy saving, and with the increase of eco-driving penetration, the effect becomes more obvious. Under the high traffic demand scenario, the implementation of eco-driving will reduce average fuel consumption and travel time within the scope of intersection significantly, and these two indicators are increasingly reducing with the increase of eco-driving penetration...
