Methods and systems for predicting travel time

A computer-readable storage medium storing instructions, when the instructions are executed, comprising:

• determining a stage of a first traffic signal light when an object enters a first traffic signal light intersection;
• based on the stage of the first traffic signal light, predicting a stage of a second traffic signal light when the object passes through a second traffic signal light intersection;
• predicting a time length for the object to pass through a sub-road section at least based on the stage of the first traffic signal light and the stage of the second traffic signal light;
• wherein a cycle of a traffic signal light includes at least two stages, and the sub-road section includes the first traffic signal light intersection and the second traffic signal light intersection.

A device for predicting travel time, comprising a processor, wherein the processor executing following method and configured to:

• determine a stage of a first traffic signal light when an object enters a first traffic signal light intersection;
• based on the stage of the first traffic signal light, predict a stage of a second traffic signal light when the object passes through a second traffic signal light intersection;
• predict a time length for the object to pass through a sub-road section at least based on the stage of the first traffic signal light and the stage of the second traffic signal light;
• wherein a cycle of a traffic signal light includes at least two stages, and the sub-road section includes the first traffic signal light intersection and the second traffic signal light intersection.
