The invention discloses a real-time urban road saturability monitoring method based on checkpoint data. The method includes the steps of monitoring the running track of each vehicle with vehicle passing information as the unit, establishing a vehicle passing information set to store the number of a series of checkpoints by which each vehicle passes in the time sequence within the set time range, adding the value of each adjacent checkpoint pair by 1, calculating the value of each adjacent checkpoint pair through all the vehicle passing information sets in mass traffic flow, and obtaining the traffic volume of a road through the specific value of the value of each adjacent checkpoint pair and a set time difference. The specific value of the road traffic volume and the road capacity is the road saturability, and therefore the real-time urban road saturability monitoring based on the checkpoint data is completed. By obtaining the checkpoint data in a central database, the value of the road saturability can be accurately calculated. The real-time urban road saturability is calculated through the real-time checkpoint vehicle passing data, and the calculation result has higher real-time performance.
