The present invention discloses a vehicle trajectory-based method for sensing allocated time of signal lights at an intersection and an electronic device. The method includes: designating a direction of an intersection, obtaining vehicle trajectory information of vehicles passing through the intersection in the direction, and extracting allocated time estimation parameters for all vehicles from the vehicle trajectory information; filtering the obtained vehicle trajectory information to remove vehicle trajectory information of a vehicle which does not stop at the intersection; calculating a vehicle arrival rate d and a vehicle departure rate a at the intersection in the direction based on the allocated time estimation parameters; selecting vehicle trajectories meeting a > d, and calculating aa−d; and performing linear regression analysis on discrete values (T3, aa−d) of the multiple vehicle trajectories of the vehicles passing through the intersection in the direction to obtain allocated time Tred for a red light at the intersection in the direction. The method makes it more convenient and intelligent to collect allocated time information of the signal lights at the intersection, and facilitates further application of intelligent transportation and vehicle energy-saving and safety optimization.
