Expressway edge calculation traffic optimization system

The invention relates to the technical field of traffic control, in particular to an expressway edge calculation traffic optimization system which determines a first reference vehicle speed and sends the first reference vehicle speed to a second edge calculation node when the traffic condition of an expressway is a non-smooth condition; the second edge calculation node obtains a plurality of segmented areas of different vehicle distance ranges according to the vehicle distance segmentation table, and determines a second suggested vehicle speed of each segmented area; the target subsection area where the target vehicle is located is determined, and the second suggested vehicle speed corresponding to the target subsection area is sent to the target vehicle, through the scheme of the invention, even if a non-smooth condition occurs in the first expressway section, the vehicles in the second expressway section can still move forwards in order, the accident sending probability is reduced, and the driving safety is
