The invention provides an intersection delay time estimation method and device. The intersection delay time estimation method includes: for any one intersection, detecting the road segment where each vehicle passing through the intersection is located, or a road segment and lane where the vehicle is located, and detecting the time point when the vehicle enters the intersection and leaves the intersection according to the road segment where the vehicle is located, or the road segment and vane where the vehicle is located; for each vehicle, according to the time point when the vehicle enters the intersection and the time point when the vehicle leaves the intersection, calculating the time for the vehicle to pass through the intersection, and calculating delay time of the vehicle at the intersection according to the time for the vehicle to pass through the intersection and time needed for the vehicle to pass through the intersection under the free stream velocity; estimating average delay time of vehicles at the intersection according to the delay time of all the vehicles passing through the interaction at the intersection. Therefore, estimation accuracy of the delay time at the intersection is improved.
