The invention relates to a low-carbon green vehicle speed guiding method for an intelligent networked vehicle, and the method is used in a mixed traffic flow scene of the intelligent networked vehicle and a common vehicle. Parameters such as the current speed of the vehicle, the distance from the vehicle to a stop line, the entrance lane and the lane where the vehicle is located, phase timing information, the current lamp color and the remaining time length are obtained through vehicle-road cooperation application data processing, the speed of the intelligent network connection vehicle is calculated on the premise that traffic signal lamps are not adjusted, and vehicle speed guiding information is issued to the intelligent network connection vehicle. No parking, less parking, gradual speed change, low oil consumption and low emission of the vehicle at the intersection are realized, and the intelligent network connection vehicle is controlled to adjust the operation condition of the whole traffic flow. Compared with the prior art, the method aims at global guidance of the intersection, multiple targets are considered, emission is reduced, and meanwhile the traffic efficiency is optimized; the method can solve the problem of vehicle speed guidance in a mixed flow environment, and is high in algorithm calculation speed. Meanwhile, the method is high in generalizability, the number of parameters needed by the algorithm is small, parameter correction is not needed, and other signal control intersections can be applied and popularized.
