The invention discloses a vehicle delay calculation method and device, relates to the technical field of traffic control, and mainly aims to improve the precision of calculating a vehicle delay result. According to the main technical scheme, the method comprises the steps of obtaining low-frequency trajectory data corresponding to a plurality of vehicles in an intersection area; performing linear fitting reconstruction on the low-frequency trajectory data of each vehicle by using a preset fitting algorithm to obtain corresponding high-frequency trajectory data of each vehicle in the intersection area; based on the high-frequency trajectory data corresponding to each vehicle, calculating an initial delay result corresponding to each vehicle in the intersection area; correcting the initial delay result corresponding to each vehicle to obtain a corrected delay result corresponding to each vehicle; and calculating a vehicle target delay result in the intersection area based on the corrected delay results corresponding to the plurality of vehicles. The method is used for calculating the vehicle delay at the intersection.
