Wherein, the lane information displayed on the lane indication board is consistent with the lane information of the road surface.
The road of the present embodiment is explained by taking four lanes as an example. The lanes from left to right of the road are respectively set as a left-turn lane, a first straight lane, a second straight lane and a right-turn lane, so that four lane information of the left-turn lane, the first straight lane, the second straight lane and the right-turn lane are respectively displayed on the lane indication boards.
It is worth to say that, the LED indicating components are arranged at each lane information position on the lane indicating boards, the number of the LED indicating components is the same as that of the lane information, and the LED indicating components are arranged below the lane information.
The LED indicating component is in communication connection with the traffic indicating service platform through a network. Specifically, the LED instructs the subassembly to include transparent casing, microcontroller, communication module and a plurality of LED lamp, transparent casing sets up on the lane sign, microcontroller, communication module and a plurality of LED lamp all set up in transparent casing, transparent casing plays waterproof, dustproof and prevent grey purpose, and do not influence the LED lamp printing opacity, wherein, still be provided with rechargeable battery in the transparent casing, rechargeable battery is used for microcontroller, communication module and LED lamp provide the electric energy, transparent shell surface still is provided with solar cell panel, solar cell panel links to each other with rechargeable battery through charging circuit in order to be used for charging for rechargeable battery.
The microcontroller is in communication connection with the traffic indication service platform through the communication module. In one embodiment, the communication module is an ethernet interface, and the communication module communicates in a TCP/IP protocol manner through the ethernet interface. In another embodiment, the communication module is a 4G module, accessed through a carrier network. In this embodiment, the wired mode or the wireless mode is not particularly limited, and may be set according to the user's needs. Therefore, when the LED indicating component is connected to the traffic indicating service platform, the LED indicating component can realize data interaction with the traffic indicating service platform and can send out an indication according to an indication instruction sent by the traffic indicating service platform.
In the present application, the arrangement of the plurality of LED lamps is as shown in fig. 3, and the arrangement may be performed in a V-shaped arrow manner.
It is worth to say that each vehicle is provided with a positioning module and a communication unit, the positioning module is used for acquiring the position information of the vehicle, and the communication unit is used for establishing communication connection with the traffic indication service platform.
In the embodiment, the positioning module adopts a Beidou positioning module which is a positioning navigation module independently researched and developed in China, and the positioning precision can reach within 1 meter. In this embodiment, the communication module adopts a 4G module, so that after the positioning module acquires the position information of the vehicle, the position information can be sent to the traffic indication service platform through the communication module.
The traffic indication service platform is a server which is developed for traffic indication and has high-speed computing capability, a plurality of servers can be arranged to form a server cluster, and the traffic indication service platform for the application is formed by the formed server cluster. The traffic indication service platform comprises an acquisition unit, a vehicle position analysis unit and an instruction issuing unit.
Specifically, after the traffic indication server platform acquires the position information of the vehicle, the acquisition unit can classify the position information of the vehicle, and then acquire the position information of the vehicle in the municipal administration district. For example, the municipal administration area of the traffic indication service platform is set as a Ningbo city, so that all vehicles with Ningbo license plates are provided with positioning modules, the traffic indication server acquires the position information of all vehicles with Ningbo license plates, but performs screening according to the Ningbo municipal administration area, and only acquires the position information of the vehicles in the Ningbo municipal administration area through the acquisition unit.
The vehicle position analysis unit is used for calling an electronic map of a municipal district, mapping the acquired position information of the vehicles in the electronic map in real time, defining an area between each intersection stop line and a lane indication board in the electronic map as a detection area, and identifying and detecting the number of the vehicles in each lane in the detection area.
Specifically, after the vehicle position analysis unit calls an electronic map of a municipal district, the obtained position information of the vehicle is mapped in the electronic map in real time, the position information of the vehicle in the embodiment is marked in the electronic map in a dot mode, and the position information of the vehicle correspondingly moves in the electronic map in the driving process of the vehicle.
The urban roads and the intersections of the urban roads displayed in the electronic map are the same as the urban roads and the intersections of the urban roads in the real scene. Thus, the vehicle position analysis unit defines an area between each intersection stop line and the lane indication board in the electronic map as a detection area, and identifies and detects the number of vehicles located in each lane in the detection area.
The vehicle position information acquired in the method is longitude and latitude information, and the longitude and latitude information of the vehicle is analyzed and processed to be displayed in an electronic map, wherein a detection area defined in the electronic map has a corresponding longitude and latitude range, and the longitude and latitude information of the vehicle is firstly compared with the longitude and latitude range of the detection area to judge whether the position information of the vehicle is located in the detection area, and if so, the lane where the vehicle is located is judged. Similarly, each lane has a corresponding longitude and latitude range, and the longitude and latitude information of the vehicle is compared with the longitude and latitude range of the lane, so that the lane where the position information of the vehicle is located is judged, and the number of the vehicles in each lane in the detection area can be further determined.
It should be noted that, because the vehicles are moving in real time on the urban road, the position information of the vehicles will change in real time on the electronic map, and if the vehicles change lanes at the intersection (go from the first straight lane to the left-turn lane), the number of vehicles in each lane in the detection area will also change in real time.
The instruction issuing unit is used for issuing a corresponding first instruction to the LED indicating assembly according to the number of vehicles in each lane in the detection area so as to control the LED indicating assembly of the corresponding lane to issue an instruction.
Specifically, as shown in fig. 2 and 3, the lanes at the intersection are a left-turn lane, a first straight lane, a second straight lane and a right-turn lane, respectively, the distance between the intersection stop line and the lane indicator is 50 meters, and a distance of 50 meters can be used to stop 10 vehicles. In the embodiment, the number of 4 vehicles is used for color change, for example, when 0-4 vehicles stay in the first straight lane, the LED indication component performs green color indication, when 5-8 vehicles stay in the first straight lane, the LED indication component performs yellow color indication, and when more than 8 vehicles stay in the first straight lane, the LED indication component performs red color indication, where performing green-yellow-red color indication by the LED indication component is merely an example, a user may make a determination according to an actual situation, and the embodiment is not particularly limited. It is worth mentioning that the LED indicating assembly may indicate in a gradual color from green to dark green as the number of vehicles parked in the first straight lane increases gradually.
Therefore, when the road lipstick lamp waits, 5-8 vehicles stay in the first straight lane, the LED indicating assembly corresponding to the first straight lane carries out yellow color indication, the LED indicating assembly corresponding to the second straight lane carries out green color indication to indicate that the second straight lane has only 5 or less vehicles, and therefore a user can drive into the second straight lane according to the lane indicator to avoid continuous congestion in the first straight lane, the number of the vehicles in each lane can be divided, the number of the vehicles in each lane is balanced, and the traffic pressure of an urban road is relieved.
It should be noted that the vehicle position analysis unit is further configured to identify and detect a driving state of a vehicle in each lane in the detection area, and the instruction issuing unit is configured to issue a corresponding second instruction to the LED indication component according to the driving state of the vehicle in each lane in the detection area, so as to control the LED indication component of the corresponding lane to issue an instruction. In this embodiment, a microcontroller in the LED indicating assembly controls the LED lamp to flash and indicate according to the second indicating instruction.
Specifically, the vehicle position analysis unit is further configured to identify and detect a driving state of the vehicle located in each lane in the detection area, the driving state including a stopped state and a forward traveling state, based on the identification and detection of the number of vehicles located in each lane in the detection area. In this embodiment, after the vehicle position information is obtained, the vehicle position analysis unit compares previous position information and subsequent position information of the vehicle, and further determines whether each vehicle in each lane moves, if the vehicle moves, it is further determined whether the number of the vehicles moving in the lane is greater than a preset number, and if the number of the vehicles moving in the lane is greater than the preset number, it is determined that the vehicles in the lane are in a forward moving state. Otherwise, when the vehicle does not move or the number of the vehicles moving in the lane is smaller than the preset number, the vehicle in the lane is determined to be in a stop state.
Therefore, when 5-8 vehicles stay in the first straight lane, the LED indicating component corresponding to the first straight lane performs yellow color indication, and the LED indicating component corresponding to the second straight lane performs green color indication to indicate that the second straight lane has only 5 or less vehicles, so that a user can drive into the second straight lane according to the lane indicator to avoid continuous congestion in the first straight lane.
When the green light at the intersection passes, the LED indicating assembly corresponding to the first straight lane carries out flowing water flicker indication on the basis of yellow color indication, and then the vehicle in the first straight lane is in a forward state, so that the normal passing of the vehicle in the first straight lane is indicated without congestion. When the LED indicating component corresponding to the second straight-going lane does not perform flowing water flicker indication on the basis of green color indication, the vehicle in the second straight-going lane is in a parking state to indicate that the vehicle in the second straight-going lane slowly passes through, and a user can drive into the lane according to own selection.
However, when the number of vehicles in the second straight lane is gradually increased, the LED indicating component corresponding to the second straight lane performs red color indication, and the LED indicating component still does not perform flowing water blinking indication, wherein the LED indicating component corresponding to the first straight lane performs flowing water blinking indication, which indicates that the vehicles in the second straight lane cannot pass due to accidents such as rear-end collision, and the like, so that the vehicles which want to enter the second straight lane in the following sequence can obtain the driving state of the vehicles in the second straight lane according to the LED indicating component corresponding to the second straight lane, thereby performing lane change in advance, and avoiding congestion caused by too much vehicles accumulated in the second straight lane due to the fact that the vehicles in the second straight lane cannot pass and each vehicle enters the second straight lane and then performs lane change.
Therefore, the traffic indication service platform can collect the position information of all vehicles in the municipal administration district, then classify, detect and judge the vehicle quantity of each lane in each intersection through the vehicle position information, and indicate the vehicle quantity and the vehicle running state through the LED indication assembly on the lane indication plate, therefore, subsequent vehicles can obtain indication information through the LED indication assembly on the lane indication plate, can know the vehicle quantity and the vehicle running state in the lane in advance, and further carry out lane change and avoidance in advance, and can slow down the traffic pressure of urban road traffic to a certain extent.
Example two;
the invention provides a traffic sign information indicating method which is applied to a vehicle, a traffic indicating service platform and a lane indication board, wherein the vehicle is in communication connection with the traffic indicating service platform to carry out data interaction, an LED indicating assembly is arranged at each lane information position on the lane indication board, the number of the LED indicating assemblies is the same as that of the lane information, the LED indicating assemblies are arranged below the lane information, and the LED indicating assemblies are in communication connection with the traffic indicating service platform through a network.
As shown in fig. 4, the method for indicating traffic sign information in the technical solution of the present invention includes the following steps:
step S100, a positioning module is arranged on a vehicle and used for sending the position information of the vehicle to a traffic indication service platform;
step S200, a traffic indication service platform acquires position information of vehicles in a municipal administration area, calls an electronic map of the municipal administration area, and maps the acquired position information of the vehicles in the electronic map in real time;
step S300, defining an area between each intersection stop line and a lane indicator in the electronic map as a detection area, and identifying and detecting the number of vehicles in each lane in the detection area;
step S400, corresponding first indication instructions are issued to the lane indicating boards according to the number of vehicles in each lane in the detection area, the LED indicating components of the corresponding lanes on the lane indicating boards are controlled to give out indications, wherein the first indication instructions control the LED indicating components to give out color indications,
according to the technical scheme defined in the steps S100 to S400, specifically, each lane of the intersection is a left-turn lane, a first straight lane, a second straight lane and a right-turn lane, the distance between the stop line of the intersection and the lane indicator is 50 meters, and 10 vehicles can be stopped at a distance of 50 meters. In the embodiment, the number of 4 vehicles is used for color change, for example, when 0-4 vehicles stay in the first straight lane, the LED indication component performs green color indication, when 5-8 vehicles stay in the first straight lane, the LED indication component performs yellow color indication, and when more than 8 vehicles stay in the first straight lane, the LED indication component performs red color indication, where performing green-yellow-red color indication by the LED indication component is merely an example, a user may make a determination according to an actual situation, and the embodiment is not particularly limited. It is worth mentioning that the LED indicating assembly may indicate in a gradual color from green to dark green as the number of vehicles parked in the first straight lane increases gradually.
Therefore, when the road lipstick lamp waits, 5-8 vehicles stay in the first straight lane, the LED indicating assembly corresponding to the first straight lane carries out yellow color indication, the LED indicating assembly corresponding to the second straight lane carries out green color indication to indicate that the second straight lane has only 5 or less vehicles, and therefore a user can drive into the second straight lane according to the lane indicator to avoid continuous congestion in the first straight lane, the number of the vehicles in each lane can be divided, the number of the vehicles in each lane is balanced, and the traffic pressure of an urban road is relieved.
It should be noted that, in defining the area between each intersection stop line and the lane indicator in the electronic map as a detection area, and identifying and detecting the number of vehicles in each lane in the detection area, the method further comprises the following steps:
step S500, identifying and detecting the driving state of the vehicle in each lane in the detection area;
and S600, issuing corresponding second indication instructions to the LED indication assemblies according to the running states of the vehicles in each lane in the detection area so as to control the LED indication assemblies of the corresponding lanes to issue the instructions, wherein the second indication instructions control the LED indication assemblies to carry out flowing water flicker indication.
According to the technical scheme defined in the steps S500 to S600, specifically, after the vehicle position information is obtained, the vehicle position analysis unit compares previous position information and subsequent position information of the vehicle, and further determines whether each vehicle in each lane moves, if the vehicle moves, further determines whether the number of the vehicles moving in the lane is greater than a preset number, and if the number of the vehicles moving in the lane is greater than the preset number, determines that the vehicle in the lane is in a forward moving state. Otherwise, when the vehicle does not move or the number of the vehicles moving in the lane is smaller than the preset number, the vehicle in the lane is determined to be in a stop state.
Therefore, when 5-8 vehicles stay in the first straight lane, the LED indicating component corresponding to the first straight lane performs yellow color indication, and the LED indicating component corresponding to the second straight lane performs green color indication to indicate that the second straight lane has only 5 or less vehicles, so that a user can drive into the second straight lane according to the lane indicator to avoid continuous congestion in the first straight lane.
When the green light at the intersection passes, the LED indicating assembly corresponding to the first straight lane carries out flowing water flicker indication on the basis of yellow color indication, and then the vehicle in the first straight lane is in a forward state, so that the normal passing of the vehicle in the first straight lane is indicated without congestion. When the LED indicating component corresponding to the second straight-going lane does not perform flowing water flicker indication on the basis of green color indication, the vehicle in the second straight-going lane is in a parking state to indicate that the vehicle in the second straight-going lane slowly passes through, and a user can drive into the lane according to own selection.
However, when the number of vehicles in the second straight lane is gradually increased, the LED indicating component corresponding to the second straight lane performs red color indication, and the LED indicating component still does not perform flowing water blinking indication, wherein the LED indicating component corresponding to the first straight lane performs flowing water blinking indication, which indicates that the vehicles in the second straight lane cannot pass due to accidents such as rear-end collision, and the like, so that the vehicles which want to enter the second straight lane in the following sequence can obtain the driving state of the vehicles in the second straight lane according to the LED indicating component corresponding to the second straight lane, thereby performing lane change in advance, and avoiding congestion caused by too much vehicles accumulated in the second straight lane due to the fact that the vehicles in the second straight lane cannot pass and each vehicle enters the second straight lane and then performs lane change.
Therefore, the traffic indication service platform can collect the position information of all vehicles in the municipal administration district, then classify, detect and judge the vehicle quantity of each lane in each intersection through the vehicle position information, and indicate the vehicle quantity and the vehicle running state through the LED indication assembly on the lane indication plate, therefore, subsequent vehicles can obtain indication information through the LED indication assembly on the lane indication plate, can know the vehicle quantity and the vehicle running state in the lane in advance, and further carry out lane change and avoidance in advance, and can slow down the traffic pressure of urban road traffic to a certain extent.
