Then, as shown in Figure 2, the first portable traffic lamp 11 on the right side turns into a red light, indicating that the vehicles on the right side stop and wait, while the second portable traffic lamp 12 on the left side turns into a green light, indicating that the vehicles on the left side are going to one after another. Drive right through the driveway.

It should be understood that if two-way vehicles pass through the same lane at the same time, they will collide. Therefore, the portable traffic command system of the embodiment of the present invention needs to command accurately, as described in detail below.

The cloud server 20 can calculate according to the recognition and analysis results of one or more first image data captured by the first portable image capture device 16 within each period of time (for example, every time the first portable traffic lamp 11 During the time between the second red light and the next green light), the number of vehicles parked on one side (such as but not limited to the right side) of the lane that is available for vehicles is used as the first number.

The cloud server 20 can calculate the time period (for example, the second portable traffic lamp 12 every During the time between the second red light and the next green light), the number of vehicles parked on the side (such as but not limited to the left side) of the lane that is available for vehicles is used as the second number.

The servo device 20 can determine which of the two sides of the lane is allowed for vehicles to pass according to the first number and the second number. For example, the servo device 20 may calculate the difference or ratio between the first quantity and the second quantity, the difference between the first quantity and the vehicle quantity threshold value, the difference value between the second quantity and the vehicle quantity threshold value, or any combination thereof to determine The maximum number of seconds that a vehicle is allowed to drive through the lane is used to determine the light-emitting state of each portable traffic lamp, that is, the time (length) of each green light or red light.

When the cloud server 20 judges that the number of vehicles parked on one side of the lane is greater than a vehicle number threshold (there are more vehicles parked on the right side of the lane as shown in Figure 2 ) and this side is red, the other side of the lane When the number of vehicles on one side is not greater than the threshold value of the number of vehicles, the cloud server 20 judges that the vehicles on this side (such as the right side) need to be allowed to pass for a long time. Two portable traffic lamps 12) shorten the time length of the green light, that is, turn from green light to red light earlier, and the first portable traffic lamp 11 on the side (such as the right side) of more vehicles changes from red light to red light sooner. Green light, according to which, quickly relieve the heavy traffic flow (such as the one on the right).

The portable traffic command system of the embodiment of the present invention can be applied to any road. The first portable traffic command device 100 and the second portable traffic command device 200 are portable devices that can be placed on different roads arbitrarily.

The time-consuming relationship is used as the basis for determining the maximum number of seconds for subsequent vehicles to pass through the lane.

Specifically, the cloud server 20 can obtain the first image data and the capture time of the second image data of the same vehicle, identify and analyze the first position of the vehicle on the road in the first image data (for example, the starting point position or the arrival position). position), and identify the second position of the same vehicle on the road in the second image data (for example, the starting point position or the arrival position), so as to calculate the distance between each vehicle passing through the lane that is available for vehicles. The actual elapsed time from one of the two sides (ie, the starting position) to the other side of the two sides (ie, the arrival position).

The cloud server 20 can determine the maximum number of seconds that other vehicles are allowed to pass through the lane according to the multiple actual elapsed times of multiple vehicles, such as but not limited to the multiple actual elapsed times of multiple vehicles. The maximum value is used as the maximum number of seconds that other vehicles are allowed to drive through the lane behind.

The cloud server 20 can compare the vehicle image data with the currently captured first image data and second image data to identify the vehicles in the historical first image data and the multiple second image data. type. Then, the cloud server 20 can learn the speeds of various vehicles that are currently running and waiting based on the vehicle speed data.

Then, the cloud server 20 can determine the maximum number of seconds that the current vehicle is allowed to travel through the lane according to the length of the lane and the number and speed of vehicles that are currently parked on each side of the lane and are driving on this lane (that is, determine the maximum number of seconds for the current vehicle to travel through the lane) A portable traffic lamp 11 or a second portable traffic lamp 12 is the time length of each green light and the time of the red light).

The cloud server 20 can control the operation of the first portable traffic command device 100 and the second portable traffic command device 200 according to the determined maximum number of seconds, including controlling the first portable traffic lights 11 and the second portable traffic lights.
