Speed prediction method and apparatus

A speed prediction apparatus, comprising:

• a first obtaining module configured to obtain traffic-effecting parameter information of a first road segment in a current time period, 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;
• a first determining module configured to determine 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;
• a second determining module configured to determine target historical traffic-effecting parameter information according to the similarity determined by the first determining module;
• a first predicting module configured to predict a first speed of a vehicle on the first road segment in a 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;
• an identifying module configured to identify at least one second road segment with a distance to the first road segment less than a second preset threshold;
• a second obtaining module configured to obtain a second speed of a vehicle on each second road segment in the current time period;
• and
• a second predicting module is configured to predict a third speed of the vehicle on the first road segment in the next time period according to the first speed and the second speed.
