Description

Lane lane display apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lane display apparatus, and includes a variable lane that is variable according to traffic volume, a lane or lane formed on a road surface on a road that restricts or expands the entrance, exit, or expansion at any time according to a change in traffic such as a bus lane or a highway toll gate. By installing lights in the center, it displays the entrance and exit of lanes or highway toll gates on the center line or bus lanes, and responds quickly to changes in traffic conditions and makes it easier for drivers to recognize their own driving lanes. It relates to a display device.

In general, a variable lane is intended to solve the traffic congestion phenomenon by varying the center line at the time of traffic congestion due to the increase of vehicles.

In the conventional variable lane display method, as shown in FIG. 1, a method of displaying a driving and a driving prohibition road by using a light indicator installed on an upper part of a lane like a general traffic light is used. Due to the risk of traffic accidents, it is unable to respond flexibly to changes in traffic volume, and to compensate for this, some people use a special vehicle to move the median to separate the centerline. Not only is it cumbersome, but it is also difficult to respond quickly to changes in traffic conditions.

In addition, in the case of bus lanes, it is difficult to change from time to time, so it is divided into a part-time or full-time operation, so it is not possible to respond flexibly depending on the traffic volume.

In order to solve this problem, conventionally, there is a method of displaying a driving road and a driving prohibition road by installing an indicator light on an upper part of a road like a general traffic light.

FIG. 1 is a structural diagram showing a conventional variable lane display method. In particular, FIG. 1 is a view illustrating a variable lane display method of a six-lane round trip (one-way three-lane) road.

As shown in Fig. 1, the first, second, third, fourth, fifth, and sixth lanes 7, 8, 9, 10, 11, and 12 are divided on the road, and both sides of the road are separated. In each of the support 50 is protruded up is hypothesized, between the support (5) is provided with an air connection 60 connecting the support 50, the air connection 60 corresponding to the center of each lane The 1st, 2nd, 3rd, 4th, 5th, 6th indicator lamps (1) (2) (3) (4) (5) (6) are provided in the position.

Each of the indicator lamps 1, 2, 3, 4, 5, and 6 is a front indicator lamp 1a, 2a, 3a, 4a, 5a, 6a, which is viewed by an upward vehicle. And the rear indicators 1b, 2b, 3b, 4b, 5b, and 6b which are instructed on the driving path of the downward vehicle, are provided on the rear of the front indicators. And " ↓ " and " X " for displaying the driving prohibited road.

As mentioned above, according to the conventional driveway and driveway prohibition display configuration, the front light 1a of the 1st, 2nd, 3rd lights 1, 2, 3 is normally used for bidirectional vehicle communication. 2a) and 3a are displayed as "0", and the back lights 1b, 2b and 3b are represented by "X", and the fourth, fifth and sixth lights 4, 5 and 6 Front indicators 4a, 5a, and 6a are indicated by " X " while rear indicators 4b, 5b and 6b are indicated by " ↓ " Will drive.

In the above situation, when congestion occurs in the direction of arrow D as shown in FIG. 1, and traffic passes in the opposite direction, the first, second, third, and fourth indicator lamps (1) (2) (3). The front indicators 1a, 2a, 3a, 4a of 4) are indicated by "↓" while the rear indicators 1b, 2b, 3b, 4b are indicated by "X". , The front indicators 5a and 6a of the fifth and sixth indicators 5 and 6 are indicated by " X " and the rear indicators 5b and 6b are indicated by " ↓ " The driving path in the direction extends to four lanes, and the driving path in the opposite direction is reduced to two lanes, so that the vehicle traveling in the direction of the arrow D is further extended to alleviate traffic congestion.

In the conventional variable lane lights as described above, most drivers habitually stare at the lanes or driving lanes of the road surface when they drive, deviating from the center line without knowing the lights installed in the air, or using a constant light signal by surrounding environment. There is a problem that the traffic accidents occur frequently because they do not recognize properly, do not recognize the time when the lane change is applied, or do not find a traffic sign. Traffic lights that are also driven by a constant brightness regardless of the road brightness, there is a problem that drivers do not properly recognize the traffic lights due to the surrounding environment.

In order to solve the above problems, the present invention provides a lane which displays an entrance and exit road such as a center line or a bus-only lane or a tollgate by installing an indicator light having a variable brightness at the center of a lane or a lane formed on a road surface. Alternatively, by installing an indicator light to display an accessible driving path, the driver can easily control the vehicle according to the traffic volume and respond quickly to changes in traffic conditions, and additionally change the brightness of the traffic light by the environment around the road. It is an object of the present invention to provide a lane display device that makes it easy to recognize a display of a traffic light.

In particular, referring to FIG. 3A, the indicator 770 includes a housing 829 of a rigid material capable of inherently protecting the indicator control code receiver 740, the indicator light source driver 750, and the indicator light source 760. To make it easier for the driver to recognize the light from the light source, the window is made of colored or colorless solid transparent members 824 and 825. In addition, the indicator light source 821 is composed of a high-brightness LED or a high-brightness bulb installed in M so as to be fully recognized during the day, and mixes the LED or the bulb by the emission color to be displayed in N colors To configure.

Referring to the operation and action of the present invention made of the above configuration are as follows.

In the traffic situation measuring unit 100 of FIG. 2, the vehicle speed measuring instrument 110 installed at a specific point measures the traffic speed of the vehicle in real time, and transmits a signal. The vehicle traffic measuring instrument 120 detects the traffic passing through the vehicle in real time. Sending a signal, CCTV 130 transmits a traffic situation screen on the road as real-time image information.

The traffic condition analysis unit 200 receiving the signal receives a signal from the vehicle speed measuring unit 110 and the vehicle traffic measuring unit 120 of the traffic situation measuring unit 100 for a predetermined average vehicle speed. The average traffic density and average image for a predetermined time after analyzing the traffic density and image moving speed on the road through image processing by receiving image information from the CCTV 130 Analyzes the average traffic situation such as analyzing the moving speed in real time.

In addition, using the average traffic conditions and the intrinsic section speed analysis function, a section speed is calculated for each lane and each vehicle direction, and the average traffic situation and the section speed are compared with each other for each lane or direction of travel. The traffic situation analysis data is calculated, such as the comparison traffic information for which the difference or the ratio is obtained, and then output to the automatic control unit 310 and the manual control unit 320 of the lane determination unit 300.

At this time, the traffic situation analysis unit 200 is necessary to calculate the average traffic situation and the section speed, such as the average speed, average traffic volume, average traffic density and average image moving speed for a predetermined time by using the built-in function A predetermined time can be arbitrarily designated to be input externally.

In particular, when calculating the section speed by using the inherent section speed analysis function, values of various parameters according to the required road conditions can be arbitrarily designated to be input externally.

The lane determination unit 300 receiving the traffic situation analysis data analyzed by the traffic situation analysis unit 200 includes an automatic control unit 310, a manual control unit 320, and a timer 330. same.

The automatic control unit 310 of the lane determination unit 300 is a predetermined reference value (variable reference value, based on the traffic situation analysis data such as the average traffic situation, section speed, comparative traffic information input from the traffic situation analysis unit 200) After determining whether the lane is changed by comparing with the change upper limit value, the lower limit value, etc. or by using the intrinsic lane determination function, selectively determine whether the lane is changed and output the control signal.

In particular, when the automatic control unit 310 determines whether to change the lane based on a preset reference value, the variable reference value that sets the level difference of the traffic situation by lane or driving direction, which is a determination standard of whether to change the lane and the traffic situation analysis. Even if the traffic condition analysis data obtained from the department 200 is equal to or greater than the variable reference value necessary for the lane change, both sides have a lower traffic limit that sets the traffic situation level that is determined to be no need for the lane change due to the heavy traffic congestion. It is possible to specify an upper limit for the change in traffic conditions that determines that there is no need to change lanes due to good communication.

In addition, the driver may be confused if the traffic signal is frequently changed within a short time, so once the signal is changed, a variable time limit that controls the vehicle not to send a lane change signal even if the traffic situation changes suddenly can be specified externally.

In addition, the lane determination unit 300 determines a lane change and displays a new lane (or lane), that is, a signal for notifying the lane change before sending a confirmation signal, that is, a predetermined signal after transmitting a predetermined time. In this case, a predetermined time at which the notice signal proceeds may be arbitrarily designated externally.

The manual control unit 320 determines whether a person changes by car based on the traffic condition analysis data of the traffic condition analysis unit 200 and the control situation of the automatic control unit 310, and manually outputs or blocks the control signal. To operate.

The timer 330 is used when a traffic congestion occurs in a predetermined time zone, after setting a lane change time zone in advance, and then scheduling the output of a control signal to the lane code transmitter 500 according to the set time zone. .

The brightness controller 400 generates a control code according to a predetermined time zone (eg, night or day) in order to control the brightness of the traffic light 620 and the indicator 770 by measuring the brightness (light quantity) around the road, Generate a control code according to a switch operated by a person (e.g. on a foggy day) or measure the amount of light around the road using a sensor that can measure the quantity of light Generates a control code corresponding to and outputs a predetermined signal to the lane code transmitting unit 500.

The lane code transmitting unit 500 includes a predetermined control signal received from the lane determining unit 300 including the automatic control unit 310, the manual control unit 320, and the timer 330, and the brightness control unit 400. After receiving a predetermined signal and synthesizing it, it is sent to the traffic light control unit 600 and the indicator control unit 700.

The traffic light control unit 600 is composed of a traffic light control unit 610 and a traffic light 620, the traffic light control unit 610 receives the control code of the lane code transmitting unit 500, the driving signal to the traffic light (620) And the traffic light 620 is driven according to the drive signal of the traffic light control unit 610.

The indicator control code generation unit 720 in the indicator control unit 710 of the indicator control unit 700 analyzes a predetermined lane code received from the lane code transmitting unit 500, and then controls the indicator lights for each lane code. Indicator control code corresponding to the lane code input by referring to the code data (indicator control code is the section of the road where the indicator is installed, the lane segment in the section and the position of the light source in the indicator, the color of the light source, the flashing cycle of the light source, and the brightness of the light source) After generating the flashing order information for the sequential flashing), and outputs to the indicator control code transmitter 730 (the flashing order information for the sequential flashing is not flashing all the lights at the same time, but to the indicator lights) Set the blinking order and make the blinking order in order to give the impression that the light flows in a certain direction by flashing it sequentially with a certain time difference. Will).

The indicator control code transmitter 730 arranges the indicator control codes received from the indicator control code generator 720 in series or in parallel, and loads a synchronization signal and transmits the signal as a wired or wireless signal (RF), or wired and wireless. Send in parallel.

The indicator control code receiver 740 separates the signal received from the indicator control code transmitter 730 for each indicator control code and transmits the signal to the indicator light source driver 750.

The indicator light source driver 750 receives the indicator control information separated from the indicator control code receiver 740 and compares it with the indicator unique identification code built into the indicator 770 in a manner such as a ROM or a switch therein. Thereafter, only a signal corresponding to the corresponding indicator unique identification code is selectively interpreted to transmit a driving signal for driving the indicator light source 760.

At this time, the indicator light source driver 750 analyzes the brightness control code received from the indicator control code receiver 740 to control the brightness by driving the indicator light source 760 using a method of varying the D / A converter or voltage. Alternatively, while transmitting a high frequency pulse signal that repeats the on-off signal of the light source, the brightness and the brightness of the indicator light source 760 may be increased by converting the width and period of the repeated on-off pulse at this time (PWM method). To control.

The indicator light source 760 uses a high-brightness LED or a high-brightness bulb installed in M, and the driver can be sufficiently recognized even during the day by mixing LEDs or bulbs by luminescent colors to be displayed in N colors.

In particular, when the indicator 770 is wirelessly controlled, a power source for driving the indicator control code receiver 740, the indicator light source driver 750, and the indicator light source 760 in the indicator 770 is provided. The solar cell is supplied by using a solar cell, wherein the solar cell is divided into a charge for charging the rechargeable battery in the indicator 770 and a drive for directly driving the indicator. The indicator 770 is directly driven by a solar cell, and when the amount of sunshine is insufficient, such as at night, the indicator 770 is driven by electric power charged in a rechargeable battery. In this sufficient daytime, the indicator 770 is directly driven while simultaneously charging the internal rechargeable battery, and in the case of the night where the amount of sunshine is insufficient, the indicator 770 is driven by the electric power charged in the rechargeable battery. .

In the case of both wired and wireless, the power supply is wired and the control code is wireless.

The indicator light 770 is manufactured in a specific structure, protruded or horizontally embedded in the road surface at regular intervals at a predetermined position for each section along a lane or a lane of the road surface, and under the control of the indicator control unit 710. Optionally on-off.

The lights 770 are provided with K lights and are installed at predetermined intervals along the lane of the road (lane installation method), or at predetermined intervals along the direction of travel of the lane at a predetermined position in the center of the lane (lane installation method). Can be

The above items are described below with reference to the accompanying drawings.

FIG. 4A illustrates an example of applying a variable lane indicator according to an exemplary embodiment of the present invention, which is a case of a variable lane comparing a traffic situation in two directions and changing a center line under different driving directions. Isoform is preferred)

The indicator of the variable lane is installed along a center line installed on the variable lane,

An example of a method of displaying the confirmation signal indicating a center line and the notice signal foretelling a newly designated center line in the indicator 770 is the same as the example of the method for displaying the variable lane indicator of FIG. 4B.

For example, an example of operation from the case where the third lane 903 is designated as the center line in FIG. 4A will be described. First, since the third lane 903 is the center line, the third lane 903 is installed along the third lane 903. The fixed signal shown in Fig. 4B is displayed on the front light ③F and the back light ③B of the indicator. Therefore, a vehicle driving in the F direction centering on the third lane (center line) is installed in the third lane. The vehicle is traveling along lanes 1, 2, and 3 while staring at the confirmation signal of the indicator front light (③F). Driving along lane 4, lane 5, and lane 6 while gazing at the confirmation signal.

When the traffic situation changes and traffic jams occur in the B direction and the traffic in the F direction is relatively small, in order to move the center line from the third lane 903 to the second lane 902, first, three driving lanes ( The third lane, which the F-direction drivers were staring at, was to be noticed as a new centerline was to be noticed to the drivers of the F-direction driving vehicles, which were reduced from lanes 1, 2, and 3 to 2 (lane 1 and lane 2). (903) The front light (②F) of the indicator light installed in the second lane 902 is turned on at the same time as the front light (③F) of the indicator light is turned off. Thus, the notice signal shown in FIG. 4B is turned on. The driving vehicle must move to lane 2 or lane 1 while the warning light is on. At this time, the vehicle driving in the B direction cannot enter lane 3 during the notice signal, and thus is installed in the third lane 903. The confirmation signal of the indicator back light (③ B) remains the same. Accordingly, the notice signal is turned on and displayed on the indicator front light ②F of the second lane 902 while the confirmation signal remains on the indicator back light ③B of the third lane. After the notice signal is displayed for a predetermined time, the second lane 902 should be determined as a center line, so that the rear lights (③ B) and the second lane (3) of the indicator of the third lane 903 that were on during the notice signal were turned on. The center line is turned on and displayed by turning off the notice signal of the indicator light (②F) on 902 and turning on the center line confirmation signal on the indicator light (②F) and the rear light (②B) on the second lane 902. The third lane 903 is completely changed to the second lane 902. Accordingly, the F-direction traveling vehicle gazing and staring at the front lamp (②F) on the newly formed second lane 902 is divided into two lanes ( While driving only by lanes 1 and 2), room B was congested Driving the vehicle is to run to the back surface, etc. (①B) 4 of the car (car 3, the car 4, the car 5, the car 6) while staring at a time on the second lane 902.

If the situation is changed and the traffic lane occurs in the F direction in the state in which the current center line is the third lane 903 as in the above example, in the example of applying the variable lane of FIG. 4A, the following operation is performed.

First, since the third lane 903 is the center line, the confirmation signal shown in FIG. 4B is displayed on the front lamp ③F and the rear lamp ③③ of the indicator lamp installed along the third lane 903. The vehicle driving in the F direction centering on the lane 903 is driven along the lane 1 and the lane 2 while staring at the confirmation signal of the indicator front light ③ F installed in the third lane 903. On the other hand, the vehicle driving in the B direction is traveling along lanes 4, 5, and 6 while staring at the confirmation signal of the back light ③B of the indicator light installed in the third lane 903. If a traffic jam occurs in the F direction and the center line is moved to the fourth lane 904, first, the driver in the direction B should be warned that the center line is being changed. Staring third lane (903) At the same time as the back light (③B) of the lamp is turned off, a notice signal is turned on at the back light (④B) of the indicator light installed in the fourth lane 904. While the vehicle is turned on, the vehicle must move to lane 5 or lane 6. At this time, the confirmation signal of the indicator light (③F) installed on the third lane 903 stared by the drivers traveling in the F direction is maintained. Therefore, the vehicle driving in the F direction is restricted from entering the lane 4 before the center line is established. Therefore, during the notice signal, the fourth signal (F) of the third lane 903 maintains a fixed signal while the confirmation signal is maintained. A notice signal turns on at the indicator back light (4B) of the lane 904.

Thereafter, after the notice signal is displayed for a predetermined time, the notice signal of the indicator lamp (F) of the indicator lamp installed on the third lane (903) and the indicator lamp (④B) of the indicator lamp (④B) on the fourth lane (904) is turned off. At the same time, the center line is turned from the third lane 903 to the fourth lane 904 by turning on a predetermined signal to the indicator light (④F) and the rear light (④B) installed on the fourth lane 904. Therefore, the number of severely congested lanes in the F direction extends from 3 to 4 (lane 1, lane 2, lane 3, lane 4), and the lanes in the B direction where traffic is desired are three to two. It is reduced to (5 lanes, 6 lanes).

FIG. 5A illustrates an application example of a bus lane according to an embodiment of the present invention. Unlike the variable lane, the driving directions are the same, but in consideration of traffic conditions, only a specific vehicle enters and runs a driving lane. This is the same as the bus lane that separates the spaces.

5A shows an example of applying a bus lane in FIG. 5A, which shows four driving lanes (lane 1, lane 2, lane 3, lane 4) traveling in the F direction. Before lane bus lane system is applied, lane 1 and lane In this case, all types of vehicles are freely allowed to enter.In this case, all the lane-only lane lights on the first and second lanes are turned off. In order to designate lane 1 as a bus lane, first, a bus lane for lane 1 should be announced. Therefore, the indicator (①F) installed on the first lane has a notice given in the example of the method of displaying the bus lane indicator of FIG. 5B. Turn on the signal and display it for a certain period of time. Therefore, vehicles that cannot drive the bus lane while the notice signal is on should move to lane 2, lane 3, and lane 4.

Afterwards, if the traffic jam is eliminated and the lane 2 is to be released from the bus lane, an indication is provided on the second lane 902 being displayed by turning on the bus lane confirmation signal. The bus lane for lane 2 is released by turning off the lamp (②F). Similarly, if the bus lane for lane 1 is to be released, the bus lane is installed in the first lane 901 displaying a confirmation signal on the bus lane. Since the indicator (1) F is also turned off, the bus-only lane for lane 1 is also released, so that all the running vehicles can enter lane 1 and lane 2 and drive. FIG. 6A shows an entry according to an embodiment of the present invention. As a diagram showing the application of the entrance guidance road indicator, the driving guidance road indicator of a vehicle installed to prevent traffic congestion when the entrance and exit roads are frequently restricted or expanded in accordance with the change of traffic conditions such as highway toll gate entrance and exit road. (A lane installation method is more preferable than a lane installation method in this case.) In FIG. 6A, there are five lanes, which is an example of a lane marking method in which indicator lights are embedded at predetermined intervals in a central location of the lane. When the situation is desired, the entrance road indicators (①F and ②F) installed on the lanes 1 and 2 are displayed on the entrance and exit guidance road lights of FIG. Induction road indicators (③F, ④F, ⑤) installed on the remaining lanes, that is, lanes 3, 4, and 5, while displaying and displaying the access road confirmation signal as shown in the method example. F) turns on and displays the prohibition of entering signals as shown in FIG. 6B. Accordingly, a vehicle passing through the vehicle is allowed to travel only in lanes 1 and 2 along the on-road taxiway indicator lights. To access lanes 1, 2, as well as lanes 3, 4 and 5 to enter all lanes, turn on the light on the taxiway indicators (③F, ④F, ⑤F) installed on lanes 3, 4 and 5 In addition to the lanes 1 and 2 as well as turning off the entrance prohibition signal and turning on and displaying the entrance signal on the roadway indicators (③F, ④F, and ⑤F) installed in the lanes 3, 4 and 5, respectively. 3, lanes 4 and 5, all lanes can be entered. If traffic volume decreases and you want to prohibit the entry of lanes 4 and 5, first, the taxiway indicators installed on lanes 4 and 5 (④F) , ⑤F) At the same time, the on-off notice signal shown in FIG. 6B is turned on and displayed on the induction road indicators ④F and ⑤F installed on the lanes 4 and 5 and displayed for a predetermined time. Therefore, the new vehicle cannot enter during the prohibition signal, and after a certain time elapses, the prohibition signal for turning off the prohibition signal which is on the roadway indicator lights ④F and ⑤F installed on the lanes 4 and 5 is turned off. At the same time, by limiting the entry of the vehicle to the lanes 4 and 5 by turning on the entry prohibition signal, all the vehicles can enter only the lanes 1, 2 and 3 as shown in FIG. 7. As an illustration of the sequence of flashing of the indicators, the indicators (F-1, F-2, F-3, F-4, F-5 ... ) By car (or lane) After installation, the indicator control code generation unit 720 generates an indicator control code including the sequential flashing information and sends it to the indicator control code transmitter 730, the indicator control code transmitter transmits it at a predetermined time interval, respectively. The indicators (F-1, F-2, F-3, F-4, F-5 ...) with other sequential flashing information are flashed sequentially according to the sequential flashing information so that the displayed signal is dynamic. For example, lights (F-1, F-2, F-3, F-4, F-5 ...) with different sequential flashing information may be displayed in the lane (or lane). Is installed on the light control code generation unit 720, and the sequential blinking information of the lights F-1, F-2, F-3, F-4, F-5 ... Generated sequentially at intervals and sent to the indicator control code transmitter 730, the indicator control code transmitter 730 receives this to the indicator at a predetermined time interval Each of the indicator control code receivers 740 inherent to the indicators F-1, F-2, F-3, F-4, F-5 ... sequentially flashes the corresponding indicators sequentially. By receiving information and repeating on and off, the user feels a dynamic sensation. Another sequential flashing method is that the indicators (F-1, F-2, F-3, F-4, F-5) differ from the above. ...) without sending different sequential codes and then sending one sequential code, each indicator (F-1, F-2, F-3, F-4, F-5 ...). ), The display is sequentially controlled by controlling the time difference that is turned on through the delay (device delaying the time to turn on the light source from the point of time of receiving the sequential flashing code).

As described above, the lane display device according to the present invention, unlike the conventional support or extension, may damage the aesthetics of the city by installing the indicator light protrudingly or horizontally from the road surface in the lane or the center of the lane. The driver can easily recognize the center line or the driving road, thereby reducing traffic accidents, and using the sensor to measure the amount of light around the road in order to control the brightness of the light source. By adjusting the light quantity of the traffic light, it is possible to drive the indicator and the traffic light of the brightness suitable for the surrounding environment of the road, and can effectively cope with changes in traffic conditions, thereby increasing the vehicle communication efficiency of the limited road.
