Embodiment 1
[0032] figure 1 A flow chart of a traffic event prediction method provided in Embodiment 1 of the present application is shown, which is described in detail as follows:
[0033] Step S11, collecting traffic data, which includes basic road network data and floating car data;
[0034] Specifically, collect traffic data in the road network equipment system, traffic vehicle system, and travel public system, for example, collect basic road network data of the road network equipment system, collect floating car data in the traffic vehicle system and travel public system, etc.
[0035] Optionally, the format of the collected traffic data is unified.
[0036] Specifically, since the formats of the traffic data of each system are different, unifying the formats of the traffic data collected from different systems helps to improve the efficiency of subsequent data processing.
[0037] Step S12, fusing the basic road network data and floating car data to obtain corresponding event feat...
Embodiment 2
[0064] Corresponding to the traffic event prediction method in Embodiment 1, Embodiment 2 of the present application provides a structural diagram of a traffic event prediction device. For ease of description, only parts related to the embodiment of the present application are shown.
[0065] The traffic event prediction device includes: a traffic data acquisition unit 21, an event feature determination unit 22, an event feature comparison unit 23, and a traffic event prediction unit 24, wherein:
[0066] Traffic data acquisition unit 21, used to collect traffic data, the traffic data includes basic road network data and floating car data;
[0067] Optionally, the traffic event prediction device includes:
[0068] The format unification unit is used to unify the format of the collected traffic data.
[0069] The event feature determination unit 22 is used to fuse the basic road network data and the floating car data to obtain corresponding event features;
