Embodiment 1
[0038] figure 1 It shows the flow chart of the traffic intelligent command and control method provided by Embodiment 1 of the present invention, figure 2 A schematic diagram of a scene of an intersection to which the method is applied is shown.
[0039] Such as figure 2 As shown, in this intersection, the intersections in four directions are located on two horizontal axes perpendicular to each other, which may be defined as X-axis and Y-axis, such as figure 2 As shown in , the intersection 203 traveling in the C direction is located on the positive semi-axis of the X axis, the intersection 201 traveling in the A direction is located on the negative semi-axis of the X axis, and the intersection 204 traveling in the D direction is located on the positive semi-axis of the Y axis , the intersection 202 traveling in the B direction is located on the negative half axis of the Y axis.

Embodiment 2
[0061] In the above-mentioned embodiment, only vehicles that will enter certain intersections are considered in the calculation of the main priority, but in practice, if a vehicle violates the rules, the pressure caused by the violation to the traffic in a certain direction should be considered, and then Increase the master priority in this direction.
[0062] Based on the above considerations, this embodiment provides a traffic intelligent command and control method, such as image 3 As shown, the method includes the following steps:
[0063] Step S301: Calculate the main priority of each direction intersection of the current intersection, the main priority is determined by the number of motor vehicles entering the intersection in this direction and the number of vehicles running red lights among the vehicles entering the intersection.
[0064] by Figure 4 The intersection scene shown as an example, where the labels are the same as figure 2 The same part is the same stru...
Embodiment 3
[0074] As mentioned above, the schemes in Embodiment 1 and Embodiment 2 only consider the current situation at the intersection, and the timeliness is relatively strong, the system judgment speed is fast, and the stability is high. , this method is slightly insufficient. In this embodiment, after considering the above-mentioned problems, an improved implementation scheme is proposed, such as Figure 5 As shown, the traffic intelligent command and control method provided in this embodiment includes the following steps:
[0075] Step S501: Calculate the number of vehicles that merge into the direction of the current intersection from each adjacent intersection of the current intersection;
[0076] by Figure 6 The traffic route diagram shown in is an illustration of the application scenario. Figure 7 yes Figure 6 A partial detailed view of the middle intersection 603. Now consider the traffic control problem at intersection 603, which is therefore the current intersection...
