Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a variable lane traffic control method according to an exemplary embodiment, and as shown in fig. 1, the variable lane traffic control method includes the steps of:
step S101, obtaining traffic flow conditions of a detected lane, and obtaining a signal lamp timing scheme and an intersection coordination scheme of a current intersection.
Specifically, referring to fig. 2, fig. 2 is a schematic diagram of a traffic intersection according to an exemplary embodiment, in fig. 2, a detected lane 11 and a variable lane 12 are adjacent, the detected lane 11 is a left-turn lane, and the variable lane 12 can change between straight driving and left turning. Take the example where the current heading indicator for the variable lane 12 is a straight heading indicator. The traffic flow condition of the detected lane 11 can be detected by the video detector, in practical application, a preset saturation condition can be set to judge the traffic flow condition of the detected lane 11, and the preset saturation condition can be that the vehicle queuing length and/or the lane occupation time reach a corresponding preset saturation threshold. For example, after the video detector detects that a large number of cars are queued up long and are not reduced for a long time, it is determined that the lane 11 starts to be over-saturated, and the traffic efficiency of the lane 11 becomes very low. When the lane change 12 is changed from the current straight lane to the left turn lane, it is helpful to reduce the vehicle saturation of the lane 11 to be detected. However, changing the lane-change 12 from the current straight lane to the left turn lane requires consideration of balancing the traffic efficiency of other lanes and other intersections
In one embodiment, the method further comprises:
judging whether a preset saturation condition is met according to the traffic flow condition of the detected lane 11, and if so, executing the following steps: and acquiring a signal lamp timing scheme and an inter-intersection coordination scheme of the current intersection.
Specifically, when the traffic flow condition of the detected lane 11 is judged to meet the preset saturation condition, the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection are triggered to be acquired, so that the optimization of the acquisition time of the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection is realized.
And step S102, carrying out coordination linkage processing on the change of the guide mark of the variable lane 12, the signal lamp timing scheme of the current intersection and the inter-intersection coordination scheme according to the traffic flow condition of the detected lane 11, the signal lamp timing scheme of the current intersection and the inter-intersection coordination scheme.

For step S102, in an embodiment, the performing coordination linkage processing on the change of the guidance indicator of the variable lane 12, the signal light timing scheme of the current intersection, and the inter-intersection coordination scheme according to the traffic flow condition of the detected lane 11, the signal light timing scheme of the current intersection, and the inter-intersection coordination scheme includes:
determining the change of the guide sign of the variable lane 12 according to the traffic flow condition of the detected lane 11 and the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, and
when the variable lane 12 guide sign changes, the changed intersection canalization is generated, and the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection are adaptively adjusted according to the changed intersection canalization.
Specifically, the change of the guide mark of the variable lane 12 is determined by comprehensive analysis according to the traffic flow condition of the detected lane 11, the signal lamp timing scheme of the current intersection and the inter-intersection coordination scheme, so that the change time of the guide mark of the variable lane 12 is more suitable.
In one embodiment, the determining the change of the guidance sign of the variable lane 12 according to the traffic flow condition of the detected lane 11 and the signal light timing scheme and the inter-intersection coordination scheme of the current intersection includes: when the guide sign of the variable lane 12 needs to be changed according to the traffic flow condition of the detected lane 11, the time for allowing the change is obtained according to the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, and the change of the guide sign of the variable lane 12 is determined according to the obtained time for allowing the change.
When the variable lane 12 guide sign is judged to need to be changed, the time for allowing the change is obtained according to the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, the time for allowing the change is the time for allowing the change of the variable lane 12 guide sign, the time for allowing the change can be a specific time point or a time period, the change of the variable lane 12 guide sign is determined according to the time for allowing the change, the time for changing the variable lane 12 guide sign can be more proper, the change of the variable lane 12 guide sign of the current intersection is coordinated with the signal lamp control of the current intersection, and the change of the variable lane 12 guide sign of the current intersection is further coordinated with the control schemes of other intersections.
The canalization is to arrange traffic signs, marking lines and the like on a lane to adjust vehicles with different driving directions and different speeds. After the direction of the variable lane 12 is changed, the intersection canalization is correspondingly changed, and the signal lamp timing scheme and the coordination scheme between intersections of the current intersection are adaptively adjusted according to the changed intersection canalization, so that the vehicle saturation of the detected lane can be reduced, the coordination with the traffic control of other intersections can be realized, and the vehicle passing efficiency of other lanes and other intersections can be guaranteed.
In one embodiment, when it is determined that the variable lane 12 guide sign needs to be changed according to the traffic condition of the detected lane 11, the method further includes:
judging whether the signal lamp control of the current intersection locks the phase, if not, switching to the execution step: and obtaining the time for allowing the change according to the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, and determining the change of the guide sign of the variable lane 12 according to the obtained time for allowing the change.
Further, the method further comprises:
if the phase is locked, a phase unlocking request is initiated for the current intersection signal lamp control, then whether the current intersection signal lamp control is unlocked is inquired according to a preset inquiry interval, and when the unlocking is inquired, the execution steps are switched to: and obtaining the time for allowing the change according to the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, and determining the change of the guide sign of the variable lane 12 according to the obtained time for allowing the change.
Specifically, the signal lamp has a phase, and the phase of the signal lamp is corresponding to the time for passing aiming at the traffic flow in different directions. The method can inquire whether the current intersection locks the phase according to the intersection number of the current intersection, and can further obtain whether the current intersection locks the phase or not by manual locking or system program locking when the current intersection locks the phase. If the intersection is not locked, the time for allowing the change can be obtained directly according to the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, and the change of the guide sign of the variable lane 12 is determined according to the obtained time for allowing the change. And if the phase is locked, keeping the original guide mark unchanged, and simultaneously initiating a phase unlocking request to the signal lamp control terminal aiming at the control of the signal lamp at the current intersection, wherein the signal lamp control terminal can be unlocked by automatic response or manually operated and unlocked by staff in front of the terminal. When the phase unlocking is inquired, the time of the change is allowed to be obtained according to the signal lamp timing scheme and the inter-intersection coordination scheme of the current intersection, and the change of the guide mark of the variable lane 12 is determined according to the obtained time of the change.
