[0031] S103: Obtain a second label vector corresponding to the initial traffic light control information according to preset weather information.

[0032] S105 , obtaining a preset annotated label vector and using the preset annotated label vector as a third label vector corresponding to the initial signal light control information.

[0033] S107, constructing the initial label vector based on the first label vector, the second label vector, and the third label vector; this may be understood as taking the sum of the first label vector, the second label vector, and the third label vector as the initial label vector.

[0038] Furthermore, A' iα =A iα / A im .

[0039] Furthermore, A' iα+1 =A iα+1 / A im .

[0040] Furthermore, the priority of the initial saturation region is the level corresponding to the initial saturation region.

The lane abnormality label is a label when a lane has a lane abnormality. The lane abnormality includes accidents, wrong-way driving, road repairs, temporary road occupation, etc., wherein each lane abnormality has several levels.

[0045] As described above, based on weather, traffic flow and manually marked labels, a label list for each control signal light information (i.e., signal light control plan) is determined, which is beneficial for signal light managers to select appropriate signal light control plans according to needs and reasonably control the signal lights in each time period.

[0049] Furthermore, the first preset duration is the duration within a single time period, which can be understood as: the value of the first preset duration is 0 to 24 hours; preferably, the value of the first preset duration is 2 hours.

[0050] In a specific embodiment, step S200 further includes the following steps:

[0057] S2013, when B ji ∈[A iα , A iα+1 ), get B ji The corresponding initial saturation area [A' iα , A' iα+1 ) and B ji The corresponding initial saturation area [A' iα , A' iα+1 ) is inserted into the first intermediate label vector as the first intermediate label.

[0061] B ji =(∑ s r＝1 C r ji ) / s.

[0062] Furthermore, the historical time period is a past time period that takes the second current time point as a starting point and is generated with a second preset duration.

[0063] Furthermore, the second current time point is a single time period corresponding to the first current time point as the second current time point.

[0064] Furthermore, the second preset duration is a single time period as the duration, that is, the value of the second preset duration is equal to a single time period.

[0065] Specifically, step S203 also includes the following steps:

[0075] S307, traverse F and when F g When F is the largest first similarity, g The corresponding initial control signal light information is used as the target control signal light information.

[0076] As described above, by measuring the similarity between the target tag list of the target time period and the initial tag set, the control signal light information suitable for the target time period is selected, thereby achieving accurate and reasonable control of the target signal light.

[0077] S400, sending the target signal light control information to the signal controller corresponding to the initial signal light ID, so that the signal controller controls the initial signal light according to the target signal light control information; those skilled in the art know that any signal controller falls within the protection scope of the present invention and will not be described in detail here.

[0078] Specifically, step S400 also includes the following steps:

[0079] S401, obtaining the target signal light control data vector G corresponding to the target signal light control information = (G1, G2, ..., G t ,……,G h ), G t is the t-th target signal light control data in the target signal light control information, t=1, 2, ..., h, and h is the number of target signal light control data.

[0082] Furthermore, F 0 Meet the following conditions:

[0083]

[0084] S407, when F 0 ≥F', the signal controller controls the initial signal light according to the current signal light control information, wherein F' is a preset similarity threshold.

[0085] S409, when F 0 <F', the signal controller controls the initial signal light according to the target signal light control information.

[0086] As described above, by comparing the target traffic light control information corresponding to the target time period with the current traffic light control information in the traffic light, the traffic light control information suitable for controlling the current time period is selected, thereby achieving accurate and reasonable control of the traffic light.
