The invention discloses a public traffic vehicle with the logistics transportation function and a logistics transportation system of the public traffic vehicle with the logistics transportation function. The public traffic vehicle comprises a public traffic vehicle body and a cargo storage area. A logistics enterprise sends a cargo transportation demand of the logistics enterprise to a logistics dispatching center, the logistics dispatching center makes a transportation plan according to the transportation demand and distributes the transportation plan to a corresponding public traffic line and the specific public traffic vehicle, the logistics enterprise transports cargoes to a transportation starting station, the cargoes are loaded to the target public traffic vehicle through station devices, after the public traffic vehicle reaches the destination, the cargoes are unloaded to station devices through a vehicle-mounted transportation device, and a transportation task is completed. By means of the public traffic vehicle and the logistics transportation system, a public logistics platform is built based on the public traffic service, transportation potential of the public traffic is sufficiently exploited, the certain logistics transportation function is achieved besides the basic passenger transportation function of the public traffic, repeated construction of freight transportation vehicle teams of different logistics enterprises is reduced, and the social logistics cost is reduced.
