Abstract
A speed prediction method and apparatus are disclosed. The method includes: obtaining traffic-effecting parameter information of a first road segment in a current time period (S101), wherein the traffic-effecting parameter information comprises at least one of a parameter of the effect of the current weather on the traffic, a parameter of the effect of an attribute of the current date on the traffic and a parameter of the effect of a special event on the traffic; determining a similarity between the traffic-effecting parameter information and historical traffic-effecting parameter information of the first road segment stored in a historical traffic database (S102), and determining target historical traffic-effecting parameter information according to the determined similarity (S103); and predicting a first speed of a vehicle on the first road segment in the next time period, according to a speed of a vehicle in a next time period of a time period corresponding to the target historical traffic-effecting parameter information, stored in the historical traffic database (S104).
