Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
The term "behind" as referred to in this application means behind the reference object as viewed in the direction of travel of the road. For example, "behind the tunnel entrance" may mean behind the tunnel entrance as viewed in the direction of travel of the road at the tunnel entrance.
It should be noted that the "tunnel entrance" mentioned in the present application is referred to the driving direction. For example, if the tunnel road is a one-way road, one port of the tunnel is a tunnel entrance and the other port is a tunnel exit. For another example, if the tunnel road is a bidirectional road, one mouth of the tunnel includes both the tunnel entrance and the tunnel exit.
Fig. 1 is a flowchart of a management method for a tunnel road according to an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:
in step S10, tunnel road information is acquired, which may include road conditions within the tunnel, such as whether there is a traffic accident, road construction, and the like. In the present embodiment, the road image in the tunnel may be acquired in a form in which a camera is provided in the tunnel. In addition, the information can also be directly obtained from a monitoring database of the traffic management department. The above two embodiments are only limited to the step of explaining the present invention, and the step of the present invention is not limited thereto, and those skilled in the art can also understand that other ways of acquiring information of a tunnel road are also applicable.
In step S20, it is determined whether or not traffic control for the tunnel is necessary. It is determined whether traffic control for the tunnel is necessary based on the information of the tunnel road obtained in step S10. In the embodiment of the present invention, whether traffic control is required may be determined by analyzing the obtained image using a processor to determine whether a traffic accident occurs in the tunnel or whether road construction is being performed inside the tunnel. Algorithms for the processor to analyze the image may be known to those skilled in the art and will not be described further herein.
In step S30, if it is determined that traffic control is necessary for the tunnel, the first instructing device is controlled to issue an entry prohibition instruction. The first indicating device may be disposed near the tunnel entrance, and in an embodiment of the present invention, the first indicating device may include at least one of a signal lamp, an electronic sign, and a voice broadcasting device, and the first indicating device may be disposed on a roadside of a road surface near the tunnel entrance, or may be disposed above the road surface near the tunnel entrance in a portal frame manner. In one example, the road includes a plurality of lanes, in which case the first indicating means may include a plurality, one for each lane. In the case that the first indicating means includes a plurality of first indicating means, step S30 may further include controlling one or more of the first indicating means to issue an entry prohibition instruction. That is, some lanes of the plurality of lanes are prohibited from passing, and other lanes are not restricted.
In step S40, if it is determined that traffic control is necessary for the tunnel, the second indicating device is controlled to issue an entry prohibition instruction. The second indicator means may be provided on the road surface in the vicinity of the turnout following the tunnel entrance. The second indicating device may include at least one of a traffic light, an electronic sign, and a voice broadcasting device, and the second indicating device may be a roadside disposed on the road surface near the turnout following the tunnel entrance, or may be a gantry disposed above the road surface near the turnout following the tunnel entrance. In one example, the turnout may be the one behind the tunnel entrance that is closest to the tunnel entrance.
In step S50, if it is determined that traffic control is necessary for the tunnel, the third instructing device is controlled to issue an instruction to decelerate the vehicle. The third indicating means may be provided on the road behind the turnout. The third indicating device may include at least one of a signal lamp, an electronic sign, and a voice broadcasting device, and the third indicating device may be disposed on a roadside of a road behind the turnout junction, or may be disposed above the road behind the turnout junction in a gantry manner. In one example, the road includes a plurality of lanes, in which case the third indicating means may include a plurality, one for each lane. The indication of vehicle deceleration may be accomplished in a variety of forms. In one example, the indication may be text, such as "traffic accident in the tunnel ahead, please slow down". In another example, the indication may be a number showing the speed limit of the vehicle, such as changing from "120" to "40".
Although steps S30, S40, S50 are shown in order in fig. 1, it will be understood by those skilled in the art that steps S30, S40 and S50 do not necessarily have to be performed in the order shown in fig. 1. In one example, step S30, step S40, and step S50 may be performed in parallel.
Fig. 2 is a flowchart of a management method for a tunnel road according to an embodiment of the present invention. The difference from the flowchart of the method for a tunnel road shown in fig. 1 is that the management method may further include:
in step S160, it is determined whether traffic control is finished, and in the case where it is determined that traffic control is finished, the first indicating device, the second indicating device, and the third indicating device are controlled to respectively give instructions for road restoration to normal. In the present embodiment, the above-described determination of whether or not the traffic control is finished may be understood as a case where it is determined that the traffic control for the tunnel is not necessary. In this case, the first indicating device provided in the vicinity of the tunnel entrance, the second indicating device provided in the vicinity of the turnout following the tunnel entrance, and the third indicating device provided on the road following the turnout may be controlled to respectively give an instruction to return the road to normal. At this time, the road returns to normal. The first, second and third indicating means here can also be understood as not sending a signal (when the default road is normal) if no traffic accident occurs in the tunnel.
Although steps S130, S140, S150 are shown in order in fig. 2, it will be understood by those skilled in the art that steps S130, S140, and S150 do not necessarily have to be performed in the order shown in fig. 2. In one example, step S130, step S140, and step S150 may be performed in parallel.
Fig. 3 is a flowchart of a management method for a tunnel road according to an embodiment of the present invention. The difference from the management method for tunnel roads shown in fig. 2 is that step S140 is replaced with step S240, step S250, step S260, and step S270.
In step S240, a traffic flow value at the tunnel entrance is collected. In this embodiment, this step may be, for example, setting a camera at the entrance of the tunnel to acquire image information at the entrance, and performing image processing by the processor to obtain the traffic flow value. In addition, the data can also be directly obtained from a database of the traffic management department.
In step S250, it is determined whether the traffic flow at the turnout is greater than a first preset value. In the present embodiment, for example, the processor may be configured to determine whether the traffic flow value is greater than the first preset value according to the traffic flow at the branch road. The preset value may be determined according to the traffic flow condition of the local road surface. Specific determination rules may be known to those skilled in the art and will not be described herein.
In step S260, the second indicating device is controlled to issue a vehicle diversion instruction when the traffic flow value at the turnout is determined to be greater than the first preset value. In the present embodiment, for example, when the processor determines that the traffic flow value is greater than the first preset value, the processor controls the second indicating device of the turnout junction arranged behind the tunnel entrance to send the vehicle diversion instruction in a wireless or wired manner, so as to guide the vehicle to pass through the turnout junction, and relieve the traffic pressure.
In step S270, in the case where the traffic flow value at the turnout is determined to be less than or equal to the first preset value, the second indicating device is controlled to issue a vehicle waiting instruction. In this embodiment, for example, when the processor determines that the traffic flow value is less than or equal to the first preset value, it may be said that there are not many vehicles at the turnout and the vehicle diversion is not needed. The processor may control a second indicating device provided at the crossing behind the tunnel entrance to issue a vehicle waiting indication in a wireless or wired manner.
Although steps S230, S260/S270, S280 are shown in order in fig. 3, it will be understood by those skilled in the art that steps S230, S260/S270, and S280 do not necessarily have to be performed in the order shown in fig. 3. In one example, step S230, step S260/270, and step S280 may be performed in parallel.
Fig. 4 is a flowchart illustrating a management method for a tunnel road according to an embodiment of the present invention. The difference from the management method for tunnel roads shown in fig. 3 is that step S240, step S250, step S260, and step S270 are replaced with step S340, step S350, step S360, and step S370.
In step S340, a predicted value is acquired. And acquiring a predicted value of the traffic flow of the turnout in a future period of time according to a prestored predicted value set of the traffic flow values of the turnout behind the tunnel entrance in different periods of time. In this embodiment, the step may be, for example, setting a camera at the turnout, counting the traffic flow data at the turnout according to different time periods, so as to establish a mathematical model, and predicting the change of the traffic flow value at the turnout in different time periods by using a statistical mathematical method, so as to establish a corresponding database. In this step, the current time may be collected first, and the current time is substituted into the established database, so as to obtain the predicted value from the established mathematical model.
In step S350, it is determined whether the predicted value of the traffic flow value of the turnout is greater than a second preset value. In the present embodiment, for example, the processor may determine whether the traffic flow value is greater than the second preset value according to the predicted traffic flow value at the branch road. The second preset value may be determined according to the traffic flow condition of the local road surface. Specific determination rules may be known to those skilled in the art and will not be described herein.
In step S360, the second indicating device is controlled to issue a vehicle diversion instruction when it is determined that the predicted value of the traffic flow value at the turnout is greater than the second preset value. In the present embodiment, for example, when the processor determines that the predicted value is greater than the second preset value, the processor may control a second indicating device of a turnout provided behind the tunnel entrance to issue a vehicle diversion instruction in a wireless or wired manner, so as to guide the vehicle to pass through the turnout, thereby relieving traffic pressure.
In step S370, in a case where it is judged that the predicted value of the traffic flow value at the crossroad is less than or equal to the second preset value, the second indicating device is controlled to issue a vehicle waiting instruction. In the present embodiment, for example, when the processor determines that the predicted value is less than or equal to the second preset value, it may be said that there are not many vehicles at the turnout junction and the vehicle diversion is not needed. The processor may control a second indicating device provided at the crossing behind the tunnel entrance to issue a vehicle waiting indication in a wireless or wired manner.
Although steps S330, S360/S370, S380 are shown in order in fig. 4, it will be understood by those skilled in the art that steps S330, S360/S370, and S380 do not necessarily have to be performed in the order shown in fig. 4. In one example, steps S330, S360/370, and S380 may be performed in parallel.
Fig. 5 is a flowchart of a management method for a tunnel road according to an embodiment of the present invention. The difference from the management method for tunnel roads shown in fig. 4 is that step S340, step S350, step S360 and step S370 are replaced with step S440, step S450, step S460 and step S470.
In step S440, a traffic value of a road behind the turnout is collected. In this embodiment, the step may be to acquire the traffic flow value of the road behind the turnout, for example, in such a manner that a camera is provided on the road behind the turnout. If the traffic flow value is directly counted at the turnout, at this time, even if the vehicle diversion is instructed by the second indicating device, traffic jam may be caused due to delay of data. Then, the traffic flow value of the road behind the turnout (a certain distance away from the turnout) is counted, so that the change of the traffic flow value of the turnout in a short time can be accurately judged. By the method, early warning can be made in advance, and the problem of traffic jam is avoided.
In step S450, it is determined whether the traffic flow value of the road behind the turnout is greater than a third preset value. In the present embodiment, for example, the processor may determine whether the traffic flow value is greater than the third preset value according to the traffic flow value behind the turnout. The third preset value may be determined according to the traffic flow condition of the local road surface. Specific determination rules may be known to those skilled in the art and will not be described herein.
In step S460, in a case where it is determined that the traffic flow value of the road behind the turnout is greater than the third preset value, the second indicating device is controlled to issue a vehicle diversion instruction. In the present embodiment, for example, when the processor determines that the traffic flow value is greater than the third preset value (in this case, it is described that a large number of vehicles pass through the turnout in a short time), the processor controls the second indicating device of the turnout arranged behind the tunnel entrance in a wireless or wired manner to issue a vehicle diversion instruction so as to guide the vehicles to pass through the turnout, thereby relieving traffic pressure.
In step S470, in the case where it is determined that the traffic flow value behind the turnout is less than or equal to the third preset value, the second indicating device is controlled to issue a vehicle waiting instruction. In the present embodiment, for example, when the processor determines that the traffic flow value is less than or equal to the third preset value, at this time, it indicates that the vehicle at the turnout junction is not passing too much in a short time, and the vehicle diversion is not needed. The processor may control a second indicating device provided at the crossing behind the tunnel entrance to issue a vehicle waiting indication in a wireless or wired manner.
Although steps S430, S460/S470, S480 are shown in order in fig. 5, it will be understood by those skilled in the art that steps S430, S460/S470, and S480 do not necessarily have to be performed in the order shown in fig. 5. In one example, step S430, step S460/470, and step S480 may be performed in parallel.
Fig. 6 is a flowchart of a management method for a tunnel road according to an embodiment of the present invention. In fig. 6, the method comprises the steps of:
in step S510, information of the tunnel road is acquired. In the present embodiment, the road image in the tunnel may be acquired in a form in which a camera is provided in the tunnel. In addition, the information can also be directly obtained from a monitoring database of the traffic management department. The above two embodiments are only limited to the step of explaining the present invention, and the step of the present invention is not limited thereto, and those skilled in the art can also understand that other ways of acquiring information of a tunnel road are also applicable. In step S520, it is determined whether traffic control is required for the tunnel. It is determined whether traffic control for the tunnel is necessary based on the information of the tunnel road obtained in step S10. In an embodiment of the present invention, whether a traffic accident occurs in the tunnel may be determined by analyzing the obtained image using a processor. Algorithms for the processor to analyze the image may be known to those skilled in the art and will not be described further herein.
In step S530, if it is determined that traffic control is necessary for the tunnel, the first instructing device is controlled to issue an entry prohibition instruction. In the embodiment of the present invention, the first indicating device may include at least one of a signal lamp, an electronic sign, and a voice broadcasting device, and the first indicating device may be disposed on a roadside on a road surface near the tunnel entrance or may be disposed above the road surface near the tunnel entrance in a portal frame manner.
In step S540, a traffic flow value at the tunnel entrance is collected. In this embodiment, this step may be, for example, setting a camera at the entrance of the tunnel to acquire image information at the entrance, and performing image processing by the processor to obtain the traffic flow value. In addition, the data can also be directly obtained from a database of the traffic management department.
In step S550, it is determined whether the traffic flow at the turnout is greater than a first preset value. In the present embodiment, for example, the processor may be configured to determine whether the traffic flow value is greater than the first preset value according to the traffic flow at the branch road. The preset value may be determined according to the traffic flow condition of the local road surface. Specific determination rules may be known to those skilled in the art and will not be described herein.
In step S560, a predicted value is obtained when the traffic flow value at the turnout is determined to be greater than the first preset value. And acquiring a predicted value of the traffic flow of the turnout in a future period of time according to a prestored predicted value set of the traffic flow values of the turnout behind the tunnel entrance in different periods of time. In this embodiment, the step may be, for example, setting a camera at the turnout, counting the traffic flow data at the turnout according to different time periods, so as to establish a mathematical model, and predicting the change of the traffic flow value at the turnout in different time periods by using a statistical mathematical method, so as to establish a corresponding database. In this step, the current time may be collected first, and the current time is brought into the established database, so as to obtain the predicted value from the established mathematical model.
In step S570, it is determined whether the predicted value of the traffic flow value of the turnout is greater than a second preset value. In the present embodiment, for example, the processor may determine whether the traffic flow value is greater than the second preset value according to the predicted traffic flow value at the branch road. The second preset value may be determined according to the traffic flow condition of the local road surface. Specific determination rules may be known to those skilled in the art and will not be described herein.
In step S580, a traffic flow value of a road behind the turnout is collected. In this embodiment, the step may be to acquire the traffic flow value of the road behind the turnout, for example, in such a manner that a camera is provided on the road behind the turnout. If the traffic flow value is directly counted at the turnout, at this time, even if the vehicle diversion is instructed by the second indicating device, traffic jam may be caused due to delay of data. Then, the traffic flow value of the road behind the turnout (a certain distance away from the turnout) is counted, so that the change of the traffic flow value of the turnout in a short time can be accurately judged. By the method, early warning can be made in advance, and the problem of traffic jam is avoided.
In step S590, it is determined whether the traffic flow value of the road behind the turnout is greater than a third preset value. In the present embodiment, for example, the processor may determine whether the traffic flow value is greater than the third preset value according to the traffic flow value behind the turnout. The third preset value may be determined according to the traffic flow condition of the local road surface. Specific determination rules may be known to those skilled in the art and will not be described herein.
In step S511, in the case where it is determined that the traffic flow value of the road behind the turnout is greater than the third preset value, the second indicating device is controlled to issue a vehicle diversion instruction. In the present embodiment, for example, when the processor determines that the traffic flow value is greater than the third preset value (in this case, it is described that a large number of vehicles pass through the turnout in a short time), the processor controls the second indicating device of the turnout arranged behind the tunnel entrance in a wireless or wired manner to issue a vehicle diversion instruction so as to guide the vehicles to pass through the turnout, thereby relieving traffic pressure.
In step S512, when it is determined that the traffic value at the entrance of the tunnel is less than or equal to the first preset value, the predicted value of the traffic value at the future time at the intersection behind the tunnel is less than or equal to the second preset value, and the traffic value at the road behind the intersection is less than or equal to the third predicted value, it indicates that a large number of vehicles do not pass through the intersection in a short time before the tunnel (i.e., a large number of vehicles do not pass through the tunnel in a short time), then the second indicating device may be controlled to indicate that the vehicles are waiting. (congestion will not be caused at this time)
In step S513, the third indicating device is controlled to indicate the deceleration and slow-down of the vehicle on the road behind the turnout, so as to avoid congestion at the turnout.
In step S514, it is determined whether or not the traffic control is finished, and in the case where it is determined that the traffic control is finished, the first indicating device, the second indicating device, and the third indicating device are controlled to give instructions to return the road to normal, respectively. In the present embodiment, the above-described determination of whether or not the traffic control is finished may be understood as a case where it is determined that the traffic control for the tunnel is not necessary. In this case, the first indicating device provided in the vicinity of the tunnel entrance, the second indicating device provided in the vicinity of the turnout following the tunnel entrance, and the third indicating device provided on the road following the turnout may be controlled to respectively give an instruction to return the road to normal. At this time, the road returns to normal. The first, second and third indicating means here can also be understood as not sending a signal (when the default road is normal) if no traffic accident occurs in the tunnel.

In this embodiment, the control center 40 may be further configured to: obtaining a predicted value of the traffic flow of the turnout in a future period of time according to a pre-stored predicted value set of the traffic flow of the turnout in different periods of time; judging whether the predicted value is larger than a second preset value or not; under the condition that the predicted value is judged to be larger than the second preset value, controlling a second indicating device 20 to send out a vehicle shunting indication; in the case where it is judged that the predicted value is less than or equal to the second preset value, the second indicating device 20 is controlled to issue a vehicle waiting instruction.
In this embodiment, the control center 40 may be further configured to: collecting the traffic flow of a road behind a turnout; judging whether the vehicle flow value is greater than a third preset value or not; under the condition that the traffic flow value is judged to be larger than the third preset value, controlling a second indicating device 20 to send out a vehicle shunting indication; and controlling the second indicating device 20 to send a vehicle waiting instruction under the condition that the traffic flow value is judged to be less than or equal to the third preset value.
Fig. 8 is a schematic view of a tunnel road according to an embodiment of the present invention. The management method for a tunnel road shown in fig. 6 is performed with the management system for a tunnel road shown in fig. 7. The control center 40 acquires the road information in the tunnel 1 from the monitoring data of the traffic police. It is determined whether traffic control needs to be set in the tunnel 1 (i.e., whether a traffic accident occurs).
When the control center 40 judges that traffic control needs to be set in the tunnel 1, the control center 40 controls the first indicating device 10 located at the tunnel entrance 2. The first indicating device 10 issues a lane-closing prompt. At this point, the vehicle can no longer enter the tunnel. Thereby avoiding the occurrence of secondary accidents in the tunnel and providing convenience for traffic departments to process traffic accidents.
In addition, the control center 40 can also obtain the traffic flow value at the tunnel entrance 2 through the monitoring data of the traffic control department (which can also be obtained by arranging a camera). And judging whether the traffic flow value is larger than a first preset value or not. In the case where it is determined that the traffic flow value is greater than the first preset value, the control center 40 obtains the predicted value of the traffic flow value of the turnout 3 in a certain period of time in the future according to a preset set of predicted values of the traffic flow values of the turnout 3 at different time periods behind the tunnel entrance. And judging whether the predicted value is larger than a second preset value or not. At this time, it is explained that a large number of vehicles pass through the turnout 3 in a future period of time. The control center 40 further obtains (or directly collects by setting a camera) the traffic flow value of the road 4 behind the turnout 2 through a database of the traffic control department. And judging whether the traffic flow value is larger than a third preset value or not. When the traffic flow value at the road 4 is greater than the third preset value, the control center 40 controls the second indicating device 30 located at the turnout 3 to indicate the vehicle to branch, so as to avoid the traffic jam which may be caused.
In addition, the control center 40 controls the third indicating device 30 on the road 4 behind the turnout 3 to indicate the vehicle to slow down in a wireless or wired manner, so as to avoid causing more serious vehicle congestion at the turnout 3.
When the control center 40 determines that the traffic value at the tunnel entrance 2 is less than or equal to the first preset value, the predicted value of the traffic value at the future time at the turnout 3 behind the tunnel is less than or equal to the second preset value, and the traffic value of the road 4 behind the turnout is less than or equal to the third predicted value, it indicates that a large number of vehicles do not pass through the turnout 3 in a short time before the tunnel (i.e., a large number of vehicles do not pass through the tunnel in a short time), then the second indicating device may be controlled to indicate that the vehicles are waiting. (congestion will not be created at this time).
When the control center 40 determines that the traffic control is finished (i.e., the accident handling in the tunnel is completed), the control center 40 controls the first indicating device, the second indicating device, and the third indicating device to respectively give an indication that the road is restored to normal.
By the technical scheme, the management method and the management system for the tunnel road can timely seal the road at the entrance of the tunnel when an accident occurs in the tunnel, and prevent the follow-up vehicle from entering the tunnel to cause difficulty in handling the accident. Meanwhile, the method and the system can dredge the following vehicles in time, and avoid the occurrence of traffic jam.
