average standard vehicle speed that is most similar to the road section and it can separate into different situations and obtain the accurate estimated vehicle speed for the remaining portion of the vehicle on the road section and thereby provide a monitoring basis for the subsequent accurate acquisition of logistics monitoring data according to some embodiments when it is determined that the current road section is congested the congestion duration time for the road section can be acquired according to the vehicle flow rate on the current road section and the estimated vehicle speed of the remaining portion and more accurate information about the state of logistics is acquired thereby and in addition when the congestion duration time is larger than the preset threshold the route of the vehicle passing through the road section can be adjusted in order to raise the logistics transportation efficiency further the embodiments of the present application can estimate the travel time of the vehicle on each road section according to the remaining portion of the vehicle on the road sections and the estimated vehicle speeds for each road section and estimates the time for the vehicle to reach one node according to the travel time of each road section prior to the node and thereby acquire a more accurate vehicle track estimate moreover the embodiments of the present application can establish the correspondence relationship between the vehicle and the waybills and monitor the state of circulation of the waybills and in addition estimate the time for the vehicle to reach the current node according to the travel.
