Embodiment 1
[0030] as Figure 1 As shown, the present embodiment provides a traffic flow data screening method comprising steps S1, S2, S3 and S4.
[0031] Step S1, the traffic data is obtained in the first time period, the traffic data includes the total number of vehicles collected by the coil detector in the first time length, the average speed of the time and the time occupancy, the length of the first time is less than the length of time of the first time period;
[0032] Step S2, the traffic data in the first time period is divided, and calculate the hourly traffic flow rate, space average speed and density corresponding to each segment of traffic data;
[0033] Step S3, the hourly traffic flow rate, spatial average speed and density corresponding to each traffic data are recorded as parameters in a sample, the sample set is obtained, and the sample set is screened to obtain the sample set after screening;
[0034] Step S4, based on the filtered sample set to calculate the value range o...
Embodiment 2
[0094] as Figure 2 As shown, the present embodiment provides a traffic flow data screening apparatus, the apparatus comprising an acquisition module 701, a partition module 702, a screening module 703 and a computing module 704.
[0095] Acquisition module 701, for obtaining traffic data in the first time period, the traffic data comprises the total number of vehicles collected by the coil detector in the first time length, the average speed of the time and the time occupancy, the first time length is less than the length of the time of the first time period;
[0096] Division module 702, for dividing the traffic data in the first time period, and calculating the hourly traffic flow rate, spatial average speed and density corresponding to each segment of traffic data obtained;
[0097] Screening module 703, for each period of traffic data corresponding to the hourly traffic flow rate, spatial average speed and density as a sample of parameters, to obtain a sample set, and the samp...
Embodiment 3
[0134] Corresponding to the above method embodiment, the present disclosure embodiment also provides a traffic flow data screening device, the traffic flow data filtering device described below and the traffic flow data screening method described above may correspond to each other.
[0135] Figure 3 Is a block diagram of the traffic flow data filtering apparatus 800 according to an exemplary embodiment illustrated. as Figure 3 As shown, the traffic flow data filtering apparatus 800 may include: a processor 801, a memory 802. The traffic flow data filtering apparatus 800 may further include a multimedia component 803, an input / output (I / O) interface 804, and a communication component 805 in one or more.
[0136]Wherein, the processor 801 is used to control the overall operation of the traffic flow data filtering device 800 to complete all or part of the steps in the traffic flow data filtering method described above. The memory 802 is used to store various types of data to su...
