Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
It should be understood that, in the following description of the specific embodiments, some repetition may not be described in detail, but should be considered as having mutual references and being able to be combined with each other, because the principles of solving the problems in the technical solutions are the same or similar.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. If there is a discrepancy, the meaning described in the present specification or the meaning obtained from the content described in the present specification is used. In addition, the terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.
For the purpose of accurately describing the technical content of the present application, and for the purpose of accurately understanding the present invention, the terms used in the present specification are given the following explanation or definition before the explanation of the specific embodiments:
special duty vehicle: refers to a vehicle that performs a particular service. For example, the special duty vehicle may be an ambulance, fire truck, police car, military car, securicar, engineering emergency car, etc.
The method for preferentially passing the special service vehicles provided by the application is described in detail below with reference to specific embodiments, and the method for preferentially passing the special service vehicles in the embodiment is applied to a control center. Referring to the flow chart shown in fig. 1, the method for preferential traffic of special service vehicles comprises the following steps:
s110: acquiring a first driving direction angle of a first special service vehicle and a current intersection where the first special service vehicle is driven; the first commute vehicle is a vehicle on duty, and the current intersection is an intersection through which the first commute vehicle is about to pass.
Specific: the method comprises the steps of obtaining a video of a first special service vehicle through a video detector arranged at a road end, judging whether the first special service vehicle is on duty according to the state or sound of a warning lamp of the first special service vehicle in the video, and obtaining a first driving direction angle of the vehicle when the first special service vehicle is on duty. Wherein the video detector may be provided on a pole of the road side. The video detector can be a radar integrated body, the radar integrated body is a common product of a millimeter radar and video in the traffic field in recent two years, and the millimeter wave radar can measure speed, distance, angle and the like.
As one implementation, the sound may be obtained from the video.
As still another implementation manner, the road end may further be provided with a sound detector, and the sound detector collects the obtained sound data, and the video detector is combined with the obtained video data to determine whether the first special service vehicle is in the duty state. The sound detector may also be arranged on a lamp post on the road side.
It should be appreciated that on duty vehicles typically have their warning lights in a flashing or specific state, and that on duty vehicles typically sound an alarm to alert surrounding vehicles or pedestrians to avoid.
In some embodiments, the video obtained by the video detector regarding the first feature vehicle may generally include identification information of the vehicle, such as license plate information, etc.; the video may also include a driving direction angle of the vehicle, for example, a driving track of the vehicle at the current intersection may be identified through a lane in which the vehicle is located; in this embodiment, the direction angle may be defined with north at 0 degrees and clockwise; the video may also include time stamp information for calculating when the first commuter vehicle arrived at the intersection.
S120: determining a second driving direction angle when the first special vehicle passes through the current intersection based on the first driving direction angle and a direction angle set allowed to be driven by the current intersection, and determining a phase corresponding to the second driving direction angle; the intersection allows the direction angle set of running to be configured in the phase of the corresponding intersection in advance.
Specifically, a set of direction angles allowed to travel by the intersection is preconfigured in the phase of each intersection, for example, for the intersection, the set of direction angles allowed to travel by the intersection includes a straight direction, a left turn direction and a right turn direction; for a T-junction, the set of allowed direction angles for the junction includes a left turn direction and a right turn direction; it should be appreciated that for other forms of intersections, the set of direction angles that are allowed to travel may be preconfigured.
Then, a direction angle with the smallest deviation from the first driving direction angle of the first special service vehicle is matched from a direction angle set pre-configured at the current intersection, namely: the closest direction angle of the two. And finally, taking the running direction corresponding to the direction angle with the smallest deviation as a second running direction angle of the first special service vehicle at the current intersection, and judging that the running track of the first special service vehicle at the current intersection is straight running, or left turning, right turning and the like. Since the direction angle set of the intersection allowed to travel is pre-configured in the phase of the corresponding intersection, when the second traveling direction angle of the current intersection is determined, the phase corresponding to the second traveling direction angle can be obtained from the configuration information.
S130: and determining a phase corresponding to the phase according to the phase corresponding to the second driving direction angle, and locking the phase corresponding to the current intersection annunciator to enable the first special service vehicle to pass preferentially.
In some embodiments, the phase corresponding to the phase may be determined using SPA mapping.
In addition, the locking process in this step is mainly divided into three cases:
case one: when the running direction of the first special service vehicle when passing through the current intersection is straight, the green light of the current intersection annunciator in the straight running stage and the left turning stage is locked.
And a second case: when the running direction of the first special service vehicle when passing through the current intersection is left turning, the green light of the current intersection annunciator in the straight-going stage and the left turning stage is locked.
Under the first condition and the second condition, no matter whether the running direction of the special service vehicle is judged to be straight or left-turning, the green light of the straight running stage and the left-turning stage of the annunciator is locked, so that errors can be avoided, and the first special service vehicle can smoothly pass through the current state under the green light state.
And a third case: when the running direction of the first special service vehicle passes through the current intersection is right turn, the green light of the current intersection annunciator in the straight-going stage and the right turn stage is locked.
In the third case, when the running direction of the vehicle is judged to be right-turning, errors are prevented from occurring, when the green light in the right-turning stage is locked, the green light in the straight-going stage is locked, and the first special service vehicle can be ensured to smoothly pass through the next intersection in the green light state.
In some embodiments, the method of prioritized traffic of the commute vehicle may further include sending a signal to the other vehicle requesting avoidance.
Specifically, the first implementation manner is as follows: the control center sends a signal for requesting avoidance to other vehicles in the same road section as the first special service vehicle so as to avoid the other vehicles. The method comprises the steps of judging which vehicles fall into the same road section as the first special service vehicle, determining through video data collected by a video detector at a road end, and determining that the vehicles collected by the same picture as the first special service vehicle are in the same road section.
The second implementation mode is as follows: the control center is communicated with the road side equipment, a signal for requesting avoidance is sent to the road side equipment in the same road section as the first special service vehicle, and the road side equipment sends a signal for requesting avoidance to other vehicles in the same road section as the first special service vehicle.
In this embodiment, the signal requesting avoidance may include a vehicle identifier of the first commuter vehicle and a traveling direction of the first commuter vehicle at the next intersection.
In some embodiments, a yielding strategy is also included when there are other second commuter vehicles on duty within the same road segment as the first commuter vehicle, and the commuter route conflicts.
Specifically, first, a second special service vehicle which is on duty exists in the same road section as the first special service vehicle, and a corresponding stage of the signal machine when the second special service vehicle passes through the current intersection is determined.
If the corresponding stage of the traffic signal when the second special service vehicle passes through the current intersection conflicts with the corresponding stage of the traffic signal when the first special service vehicle passes through the current intersection, the controlled time of the traffic signal when the first special service vehicle and the second special service vehicle pass through the current intersection is required to be determined respectively, when the controlled time has an intersection, the traffic vehicle with priority passing is determined according to the traffic priority of the first special service vehicle and the second special service vehicle, and the green light of the traffic signal of the current intersection on the corresponding stage of the traffic vehicle with high service priority is locked, so that the special service vehicle with high service priority passes through preferentially. Wherein, the priorities of various service can be preconfigured in the control center.
The method for preferentially passing the special service vehicle according to another embodiment of the present application may further include a step of controlling the traffic signal of the next intersection in advance, as shown in fig. 2, which is a flowchart of the method for preferentially passing the special service vehicle according to the present embodiment. The control of the current intersection annunciator is the same as that of the above embodiment, so that the description thereof is omitted here.
S140: determining a next intersection where the first special vehicle runs according to the second running direction angle of the first special vehicle and the upstream-downstream relation of the road where the first special vehicle is currently located; the next intersection is a downstream intersection of the current intersection.
The upstream-downstream relationship of the road is prestored in the central control platform.
The relationship of the current intersection and the next intersection is first described below with reference to fig. 3. Fig. 3 shows a schematic road diagram, in which the vehicle represents a first special purpose vehicle, and the arrow direction is the driving direction of the first special purpose vehicle. For the current position of the first special service vehicle, the intersection A is the current intersection, namely the intersection where the first special service vehicle is about to pass, and the intersection B is the next intersection, namely the next intersection where the first vehicle is about to pass after passing through the current intersection A.
After determining the next intersection based on the upstream-downstream relationship between the second driving direction angle and the road, the traffic signal at the intersection needs to be controlled, specifically:
s150: and locking green lights of the annunciators of the next intersection in the straight-going stage and the left-turning stage.
In this embodiment, since the right turn direction does not generally need to run according to the traffic light color, when determining the next intersection where the first special vehicle runs, the green light of the straight-going stage and the left turn stage of the next intersection may be locked in advance.
It should be understood that, in the forward running process of the special service vehicle, when the next intersection becomes the current intersection, the method provided in the above embodiment should be executed, and in this embodiment, the green lights in the straight running stage and the left turning stage of the next intersection are locked in advance, so as to avoid the situation that the traffic lights are not switched timely due to the special situation, and the running of the special service vehicle is affected.
According to the special service vehicle priority passing method, the running direction of the special service vehicle at the current intersection is determined through matching of the running direction angle of the special service vehicle with the preset running direction angle of the current intersection, so that green lights at corresponding stages are locked, the special service vehicle passes preferentially, and service execution is more efficient on the premise that traffic safety is guaranteed. In addition, the right-left direction or the right-left direction can be locked preferentially, judgment errors can be avoided, and smooth passing of special service vehicles is further guaranteed. In addition, the method and the device ensure the passing efficiency of special service vehicles by providing a way giving way for other vehicles. The method for efficiently passing the service vehicles in order is further provided when the plurality of service vehicles have route conflicts, so that the service vehicles pass more scientifically. In addition, the signal state of the next intersection is controlled in advance, so that the situation that the traffic light color of the next intersection signal is not switched and the passing of special service vehicles is delayed in time is avoided.

And the locking module 430 is configured to determine a phase corresponding to the phase according to the phase corresponding to the second driving direction angle, and lock the phase corresponding to the current intersection signal, so that the first special service vehicle passes preferentially.
