step S210, the cloud server obtains relevant real-time road condition data of the tidal lane.
It can be understood that the cloud server can obtain relevant real-time road condition data of each tidal lane in a certain geographic area, and control and decide the dynamic adjustment of each tidal lane, and the dynamic adjustment of one tidal lane is taken as an example for explanation.
In this embodiment, the tidal lane related real-time traffic data includes the current driving direction of the tidal lane, and also includes real-time traffic data within a preset range of the tidal lane, which may include at least part or all of traffic flow related data collected by the road end collecting device, vehicle real-time location data output by the vehicle-mounted location module, and vehicle navigation data output by the vehicle-mounted navigation module or the navigation application server, for example.
The cloud server can update and record the current driving direction of the tidal lane, and the current driving direction of the tidal lane can be obtained by reading the recorded data.
It will be appreciated that the tidal lane preset range may include, for example, part or all of the lanes of part or all of the road section in which the tidal lane is located, and/or part or all of the lanes within the preset range outside of the road section in which the tidal lane is located.
The real-time traffic data within the predetermined range of tidal lanes may include real-time traffic data within the predetermined range of tidal lanes in a current driving direction along the tidal lane and in an opposite driving direction along the tidal lane.
In some embodiments, a road end collecting device (e.g., a camera device, and/or a radar) is disposed at a crossing, above a lane, and/or at a roadside and the like within a preset range of a tidal lane, and the road end collecting device can collect vehicle related data according to a preset collecting frequency, such as vehicle image data collected by the camera device, vehicle monitoring data collected by the radar and the like, and obtain the number, speed and the like of the passing vehicles according to the traffic flow related data, and further, can identify the license plate number of the vehicle according to the traffic flow image data. The road end acquisition device can report the acquired data to the cloud server according to a preset reporting frequency. The collection frequency and the reporting frequency can be the same or different.
In some embodiments, the vehicle-mounted positioning module of the vehicle running on the road may report the vehicle positioning data to the cloud server according to a preset reporting frequency, and the cloud server may obtain the real-time position and the running speed of the vehicle according to the real-time vehicle positioning data. In a specific implementation, after the vehicle detects that the vehicle runs into the preset range of the tidal lane, the vehicle positioning data can be automatically reported to the cloud server according to the preset reporting frequency until the vehicle leaves the preset range. In this application, the car machine may be an electronic controller of a vehicle, or may be a mobile terminal loaded in the vehicle, such as an intelligent terminal like a mobile phone, a tablet computer, and a navigator.
In some embodiments, the vehicle navigation module or the navigation application server of the vehicle running on the road sends the navigation data of the vehicle to the cloud server, and the cloud server can determine whether the vehicle passes through the tidal lane section, the predicted arrival time and the like according to the vehicle navigation data.
And step S220, the cloud server obtains traffic jam prediction data according to the relevant real-time road condition data of the tidal lane.
The cloud server can obtain traffic jam prediction data of a road section where the tidal lane is located according to relevant real-time road condition data of the tidal lane through a preset lane jam algorithm (such as a yolo algorithm). The traffic congestion prediction data may comprise respective traffic congestion prediction data for two opposite driving directions of a road segment in which the tidal lane is located
It can be understood that the cloud server can obtain traffic jam prediction data of a road section where the tidal lane is located according to relevant real-time road condition data of the tidal lane periodically or when a preset trigger condition is met.
In other embodiments, the cloud server may further obtain related historical road condition data of the tidal lane in the same time period, and obtain traffic congestion prediction data of a road section where the tidal lane is located according to the related real-time road condition data and the related historical road condition data.
In step S230, if the cloud server determines that the tidal lane needs to be changed according to the traffic congestion prediction data, the cloud server generates a tidal lane change instruction including tidal lane change data, and sends the tidal lane change instruction to the traffic light control system.
In some embodiments, the traffic congestion prediction data may be, for example, predicted traffic flows in two opposite driving directions of a road segment where the tidal lane is located, and if the predicted traffic flow in one direction is greater than a first preset threshold and the predicted traffic flow in the other direction is less than a second preset threshold, it is determined that the tidal lane needs to be changed, where the first preset threshold is greater than the second preset threshold.
If the cloud server determines that the tidal lane does not need to be changed according to the traffic jam prediction data, the cloud server returns to execute the step S220; and if the tide lane change is determined to be needed, generating a tide lane change instruction containing tide lane change data and sending the tide lane change instruction to the traffic light control system.
The tidal lane change data may include tidal lane markings, the direction of travel after a tidal lane change. In some embodiments, the tidal lane change data may also include change times, periods of congestion, and the like.
In step S240, if the traffic signal control system receives the tide lane change trigger instruction, the traffic signal corresponding to the tide lane is displayed according to the preparation change mode according to the tide lane change data.
In some embodiments, the traffic signal lamp control system comprises a controller which is arranged near a tidal lane and electrically connected with the traffic signal lamp, and the cloud server sends a tidal lane change instruction to the controller after determining that the tidal lane needs to be changed; the controller responds to the tide lane change instruction and outputs a control signal according to tide lane change data, so that a traffic signal lamp corresponding to the tide lane is displayed according to a prepared change mode.
In other embodiments, the traffic signal lamp control system comprises a remote control server, and after determining that a tide lane needs to be changed, the cloud server sends a tide lane change instruction to the remote control server; and the remote control server responds to the tide lane change instruction and outputs a remote control signal to display the traffic signal lamp corresponding to the tide lane according to a prepared change mode. Furthermore, the traffic light control system can also comprise a controller which is arranged near the tidal lane and electrically connected with the traffic light, and the remote control server can control the traffic light corresponding to the tidal lane to display according to the prepared change mode through the controller.
The traffic signal lamp corresponding to the tidal lane can be a lane signal lamp post arranged at the starting point and/or the ending point of the tidal lane, a lane signal lamp board arranged above the lane at the starting point and/or the ending point of the tidal lane, a motor vehicle signal lamp arranged at the intersection at the starting point and/or the ending point of the tidal lane, and the like.
In some embodiments, causing the traffic lights corresponding to the tidal lane to display in the preparatory change mode includes causing the traffic lights at the beginning of the tidal lane to display the no entry signal to prevent the vehicle from continuing to enter the tidal lane and causing the traffic lights at the end of the tidal lane to display the go-through signal all the time along the direction of the vehicle ahead of the change of the tidal lane until it is determined that the preset switching condition is met.
The meeting of the preset switching condition may include, for example: displaying the traffic signal lamps corresponding to the tidal lanes according to a prepared change mode until a preset time interval is reached; or the isolation guardrail of the tidal lane completes the movement corresponding to the change; alternatively, both may be satisfied.
It can be understood that, if the tidal lane change instruction includes a change time, the traffic light control system may perform the step of displaying the traffic light corresponding to the tidal lane according to the preliminary change mode after counting the change time.
In step S250, if it is determined that no vehicle is running within the preset range of the isolation barrier on the tidal lane, the cloud server outputs a barrier change instruction to the barrier control system, so that the barrier driving device drives the isolation barrier to move correspondingly to the lane change.
In some embodiments, the cloud server may determine whether vehicles are traveling within a preset range of the isolation barrier on the tidal lane according to the position of the tidal lane, the data collected by the road end collecting device, the real-time vehicle positioning data, and/or the vehicle navigation data.
It will be appreciated that the barrier control system may include a controller and/or remote control server located adjacent the tidal lane, and a barrier drive for driving the isolation barrier, the barrier drive being responsive to control commands from the controller and/or remote control server adjacent the tidal lane to drive the isolation barrier to move in response to a lane change, for example to move the isolation barrier from one side of the tidal lane to the other, so that the isolation barrier is located to the right of the direction of travel of the tidal lane both before and after the tidal lane change.
In step S260, if it is determined that the isolation barrier of the tidal lane completes the movement corresponding to the current change, the cloud server switches the display of the traffic signal light corresponding to the tidal lane from the ready-to-change mode to the display of the post-change mode corresponding to the driving direction after the change.
After the barrier control system finishes moving the isolation barrier, a moving completion notification is sent to the cloud server, the cloud server can determine that the isolation barrier of the tidal lane completes moving corresponding to the change according to the moving completion notification, and then a switching instruction is sent to the traffic signal lamp control system, so that the traffic signal lamp control system controls the traffic signal lamp corresponding to the tidal lane to switch from displaying according to a prepared change mode to displaying according to a mode after the change corresponding to the driving direction after the change.
In some embodiments, causing the traffic signal light corresponding to the tidal lane to be displayed in the post-change mode corresponding to the post-change driving direction includes displaying the signal light corresponding to the lane in the motor vehicle signal light groups at the start point and the end point of the tidal lane along the post-change driving direction of the tidal lane, controlling the color of the signal light according to a preset rule, and causing the signal light corresponding to the lane not to be displayed in the motor vehicle signal light groups at the start point and the end point in the pre-change driving direction of the tidal lane or causing the signal light to display the no-pass signal.
In some embodiments, the lane real-time dynamic adjustment method further includes: and if the road section where the corresponding vehicle passes through the tide lane is determined according to the vehicle navigation data and the tide lane change data, sending a tide lane change notice to a vehicle machine corresponding to the vehicle. In one specific implementation, an on-board navigation module or a navigation application server of a vehicle running on a road sends vehicle navigation data to a cloud server, the cloud server can judge whether the vehicle will pass through a road section where a tidal lane is located in a congestion period according to the vehicle navigation data and the tidal lane change data, and if the judgment result is yes, a tidal lane change notification and the like are sent to a corresponding vehicle machine of the vehicle.
In some embodiments, the lane real-time dynamic adjustment method further includes: and obtaining the license plate number of the vehicle passing through the road section where the tide lane is located, and sending a tide lane change notice to a corresponding vehicle machine of the vehicle according to the corresponding relationship between the pre-stored license plate number and the vehicle owner communication number.
