The invention, which relates to the intelligent traffic industry, discloses a high efficient and real-time analytical method of vehicle fake license suspicion and an apparatus thereof. According to the invention, all data for fake license analyses are stored in a memory; it is maintained that each vehicle is corresponded to only one record during the processing process and the total amount of the data is controlled; and it is determined whether a vehicle a fake licensed one by calculating whether a time difference of the same vehicle between two checkposts is less than a time threshold between the two checkposts, so that it can be rapidly and accurately determined whether there is fake license suspicion. Because distance between checkposts are various and the speed limits are different, time for driving a distance between each two checkposts is different from others; therefore, the shortest time for passing through the two checkposts can be determined by calculating a time threshold between the two checkposts; and the determination result is more reasonable than an arranged unified global time threshold. Moreover, a memory analytical mode is used to replace a traditional Oracle database query analytical mode; therefore, efficiency is high and operability is strong; and an operation burden of the Oracle database is reduced.
