In the embodiment of the present application, the background management center 20 may be a background server, a background traffic guidance center, or other management devices. The emergency vehicle (such as a fire rescue 119 vehicle, a medical rescue 120 vehicle, a police officer emergency service vehicle, etc.) may be equipped with a Positioning device, such as a GPS (Global Positioning System), which may be used by the back-end management center 20 to actively acquire navigation information from the emergency vehicle, or used by the emergency vehicle to actively send navigation information to the back-end management center 20, which is not limited herein. Alternatively, the emergency vehicle may directly send the navigation information to the back-office management center 20; or the starting place and the destination may be sent to the back-office management center 20, and the back-office management center 20 may plan an optimal route according to the starting place and the destination of the emergency vehicle and determine the optimal route as the navigation route of the emergency vehicle. Further, the background management center 20 may send the navigation information of the emergency vehicle to the signal controller 30, and the signal controller 30 may determine the lane to be passed of the emergency vehicle at the planar intersection according to the navigation information, that is, select the lane to be passed of the emergency vehicle from the lanes provided with the traffic lights, and control the first indicator of the traffic light on the lane to be passed to send the warning passing light signal or the passing prohibition light signal, so as to prohibit the social vehicle from entering the lane to be passed. The lane to be traveled may be more than one, for example, at least one entrance lane to be traveled and at least one exit lane to be traveled including the level crossing. The signal controller 30 may simultaneously control the traffic signal lamps on the lanes to be passed to send out the warning traffic light signal or the traffic prohibition light signal, or sequentially control the traffic signal lamps on the lanes to be passed to send out the warning traffic light signal or the traffic prohibition light signal according to the sequence of the emergency vehicles passing through, which is not limited in the embodiment of the present application. It is understood that the emergency vehicle may directly transmit the navigation information to the signal controller 30 without passing through the rear management center 20; the departure point and the destination may be directly transmitted to the signal controller 30 so that the signal controller 30 plans the navigation route, which is not limited herein.

In a possible embodiment, the signal controller 30 may be specifically configured to receive the navigation information sent by the back-office management center 20, determine a lane to be passed through of the emergency vehicle at the planar intersection according to the navigation information, obtain a first distance between the emergency vehicle and an entrance of the lane to be passed through which the emergency vehicle first enters, and adjust a first indicator of a traffic signal lamp on the lane to be passed through which the emergency vehicle first enters to send a warning passing light signal or a passing-prohibition light signal when the first distance is less than or equal to a first preset distance, so as to prohibit the social vehicle from entering the lane to be passed through which the emergency vehicle first enters.

Specifically, after the navigation information of the emergency vehicle is acquired, the direction of the emergency vehicle driving to the plane intersection can be determined, so that the lane to be passed through, which the emergency vehicle firstly drives into at the plane intersection, and the lane to be passed through, which the emergency vehicle finally drives into at the plane intersection, can be known. The signal controller 30 may directly obtain the real-time position of the emergency vehicle, or the back-office management center 20 may obtain the real-time position of the emergency vehicle and feed the real-time position back to the signal controller 30. The signal controller 30 may estimate a first distance between the emergency vehicle and an entrance of the first-entered lane to be traveled according to the real-time position of the emergency vehicle, and may control a traffic signal lamp on the first-entered lane to be traveled to emit a warning light signal to be traveled or a no-travel light signal to be traveled when the first distance enters a first preset distance range, so as to empty the first-entered lane to be traveled in advance. The signal controller 30 may store a first preset distance in advance, where the first preset distance may be 1000 meters, 800 meters, 500 meters, or other values. When the emergency vehicle reaches a certain distance range, the lane to be passed which is firstly driven in is emptied, so that the waste of lane resources caused by too early emptying of the lane to be passed which is firstly driven in can be avoided.

In a feasible embodiment, the signal controller 30 may be specifically configured to receive the navigation information sent by the back-end management center 20, determine a lane to be passed by the emergency vehicle at the planar intersection according to the navigation information, obtain a time period required by the emergency vehicle to reach an entrance of the first lane to be passed, and adjust the first indicator of the traffic signal lamp on the first lane to be passed to send out a warning passing light signal or a passing prohibition light signal when the required time period is less than or equal to a passing period of the first lane to be passed at the planar intersection, so as to prohibit the social vehicle from entering the first lane to be passed.

Specifically, the signal controller 30 may directly or indirectly obtain the real-time position of the emergency vehicle, and may obtain the driving speed of the emergency vehicle. The running speed may be reported directly by the emergency vehicle itself, or may be measured by a speed detector arranged on the roadside and reported to the signal controller 30, or may be reported to the background management center 20 by the emergency vehicle, and then sent to the signal controller 30 by the background management center 20, and so on. The distance between the emergency vehicle and the entrance of the first-to-be-passed lane is estimated according to the real-time position of the emergency vehicle, and the time length required for the emergency vehicle to reach the entrance of the first-to-be-passed lane can be estimated according to the distance and the running speed of the emergency vehicle. When the required time is within a certain preset time range, the traffic signal lamp on the firstly-entered lane to be passed can be controlled to send out a warning passing light signal or a passing prohibition light signal so as to empty the firstly-entered lane to be passed in advance. The preset time duration may be a certain fixed time duration set in advance, such as 3 minutes, 2 minutes, 90 seconds, or other values; the preset time duration may also be a release period of the to-be-passed lane which is driven first at the plane intersection, and the release period may include a green light time duration, a green flashing time duration, a yellow light time duration, and a red light time duration, for example, the green light time duration is 30 seconds, the green flashing time duration is 2 seconds, the yellow light time duration is 3 seconds, and the red light time duration is 25 seconds, and then the release period is 60 seconds. The method has the advantages that the first entering lane to be passed is emptied within a certain time range before the emergency vehicle arrives, so that the waste of lane resources caused by the early emptying of the first entering lane to be passed can be avoided, and the release period of each lane at the plane intersection cannot be influenced.

In a possible embodiment, the signal controller 30 may be further configured to obtain a second distance between the emergency vehicle and an entrance of a next lane to be traveled when the emergency vehicle enters the first lane to be traveled, and adjust the first indicator of the traffic signal on the next lane to be traveled to emit the warning light signal or the no-travel light signal when the second distance is smaller than or equal to a second preset distance, so as to prevent the social vehicle from entering the next lane to be traveled.

Specifically, the signal controller 30 may continue to obtain the real-time position of the emergency vehicle when the emergency vehicle enters the first lane to be traveled. Optionally, the signal controller 30 may directly obtain the real-time position of the emergency vehicle sent by the positioning device on the emergency vehicle; or the emergency vehicle feeds back the real-time position to the background management center 20, and then the real-time position is sent to the signal controller 30 by the background management center 20; the vehicle monitoring node on the lane to be traveled, which is driven first, may also monitor the emergency vehicle and feed back the position information to the signal controller 30, and so on. The vehicle monitoring node may include, but is not limited to, at least one of a video capture device (e.g., a camera), a geomagnetic sensor, a piezoelectric sensor (e.g., a gravity sensor), a photoelectric sensor (e.g., a laser sensor, an infrared sensor, etc.), an ultrasonic sensor, and a capacitive sensor. The signal controller 30 may estimate a second distance between the emergency vehicle and an entrance of a next lane to be traveled according to a real-time position of the emergency vehicle in the lane to be traveled that is driven first, and may control a traffic signal lamp on the next lane to be traveled to emit a warning light signal or a no-travel light signal when the second distance is within a second preset distance range, so as to empty the next lane to be traveled in advance. The signal controller 30 may have a second preset distance set therein in advance, and the second preset distance may be 1000 meters, 800 meters, 500 meters, or other values. The traffic signal lamps on the corresponding traffic lanes are controlled by adopting a separate control mode aiming at different traffic lanes to be passed, so that the waste of lane resources caused by the early emptying of the next traffic lane to be passed can be effectively avoided.

In a possible embodiment, the signal controller 30 may be further configured to obtain a time period required for the emergency vehicle to reach the entrance of the next lane to be traveled, and when the required time period is less than or equal to a fixed time period, adjust the first indicator of the traffic signal lamp on the next lane to be traveled to send out the warning light signal or the traffic prohibition light signal to prohibit the social vehicle from entering the next lane to be traveled.

The fixed time period may be a preset time period, such as 2 minutes, 90 seconds, 60 seconds, or other values. The next lane to be passed is emptied within a certain time range before the emergency vehicle arrives, so that the waste of lane resources caused by the premature emptying of the next lane to be passed can be avoided.

In a possible embodiment, the signal controller 30 may be further configured to obtain real-time position information of the emergency vehicle when the emergency vehicle enters the first to-be-passed lane, and adjust a first indicator of a traffic signal lamp located behind the emergency vehicle on the first to-be-passed lane to send a clear-to-pass light signal to allow the social vehicle to enter the first to-be-passed lane.

Specifically, the signal controller 30 may control a traffic signal lamp located at a rear position of the emergency vehicle (i.e., an area that the emergency vehicle has traveled) on the lane to be traveled that is first entered, to emit a traffic permission light signal, so as to allow the social vehicle to enter the lane to be traveled that is first entered and to travel behind the emergency vehicle, according to a traveling position of the emergency vehicle on the lane to be traveled that is first entered. The traffic signal lamp on the first-to-pass lane to be driven in is regulated and controlled by automatically monitoring the position change of the emergency vehicle, manual control is not needed, the resource utilization rate of the first-to-pass lane to be driven in can be increased, and the passing efficiency of social vehicles can be improved while the requirement of rapid passing of the emergency vehicle is met. It can be understood that, after it is detected that the emergency vehicle completely runs out of the first to-be-passed lane, the signal controller 30 may automatically control all traffic signal lamps on the first to-be-passed lane to send out the passing-permission light signals, so as to allow the social vehicle to enter the first to-be-passed lane.

Similarly, the signal controller 30 may be further configured to obtain real-time position information of the emergency vehicle when the emergency vehicle enters the next lane to be passed, and adjust the first indicating device of the traffic signal lamp located at the rear position of the emergency vehicle on the next lane to be passed to send out a light signal for allowing passage, so as to allow the social vehicle to enter the next lane to be passed.

For example, the spacing between any two adjacent traffic lights on a lane may be 3 meters, 5 meters, 7.5 meters, 10 meters, 12 meters, or other values. For another example, along the driving direction of the traffic lane, the distance between two adjacent traffic lights gradually decreases; or the distance between two adjacent traffic lights is gradually increased along the driving direction of the traffic lane. Of course, the distance between two adjacent traffic lights on a traffic lane may also be varied randomly or in other variations, and does not necessarily exhibit the above-mentioned exemplary gradually decreasing or gradually increasing variations in a certain direction. Further, the main housing of the traffic signal may be partially buried under the ground of the traffic lane when the traffic signal is installed on the ground of the traffic lane, or the main housing of the traffic signal may be attached to the road surface of the traffic lane.

In practical applications, traffic lights may be disposed on part or all of the entrance/exit lanes of the planar intersection, wherein the manner of disposing the traffic lights on part or all of the entrance lanes may be the same or similar.
