Description

Auxiliary traffic light control server for right-turning vehicles and its operating method

The following embodiments relate to an auxiliary traffic light control server for right-turning vehicles and an operation method thereof.

In general, drivers of right-turning vehicles (left-turning vehicles in countries where non-signalized turns are left turns) at signalized intersections use two signalized crosswalks (signaled crosswalks (hereinafter referred to as first crosswalks) that meet before turning at intersections) to pass through signalized intersections. , Pass through the signal crosswalk (hereinafter referred to as the second crosswalk) that meets after turning at the signal intersection. At this time, if there is no separate traffic light for vehicles turning right, the driver must pass the first crosswalk and the second crosswalk by referring to the signals of the first and second crosswalks.

However, since the pedestrian traffic lights of the first and second crosswalks are installed so that pedestrians who want to cross can easily see them, it is often difficult for drivers of right-turning vehicles to check pedestrian signals that are lighted almost at right angles to the vehicle's traveling direction.

In addition, if only the pedestrian signal at the crosswalk is referenced, there is a high possibility that the pedestrians (cyclists, motorcycles, PMs (Personal Mobility, etc., Personal Mobility), hereinafter referred to as crossing pedestrians)) may not be recognized and pedestrians crossing quickly without being able to check the vehicle in progress. It is causing an accident.

According to one embodiment of the present invention, an auxiliary traffic light control server for a right turning vehicle and an operating method thereof may be provided.

According to an embodiment of the present invention, lighting schemes of the first and second lights of the auxiliary traffic lights corresponding to the signals of the first crosswalk and the second crosswalk may be determined.

According to an embodiment of the present invention, an additional lighting method for the second light of the auxiliary traffic light may be determined in consideration of whether or not a vehicle from another outlet of the intersection is merging.

According to an embodiment of the present invention, an additional equalization method of a second light of an auxiliary traffic light may be determined using lane information of an intersection.

According to an embodiment of the present invention, a method for controlling an auxiliary traffic light for a vehicle making a right turn at an intersection includes acquiring a signal of a first crosswalk through which a vehicle entering the intersection in a first direction passes; turning the first light of the auxiliary traffic light green or red in response to the signal of the first crosswalk; obtaining a signal of a second crosswalk through which the vehicle turns right at the intersection and proceeds in a second direction; turning the second light of the auxiliary traffic light green, red, or yellow in response to the signal of the second crosswalk; can include

According to the above-described problem solving means of the present disclosure, since an auxiliary traffic light capable of providing signal information of a crosswalk to a right-turning vehicle is provided, traffic safety and efficiency can be improved.

In addition, by configuring auxiliary traffic lights with two lights and making each light correspond to the first and second crosswalks, the driver can intuitively grasp the signal conditions of the first and second crosswalks.

In addition, since additional lighting of auxiliary traffic lights is determined in consideration of the possibility of collision with a vehicle flowing out from another outlet of the intersection, driving stability can be further reconsidered.

4 illustrates an intersection according to an exemplary embodiment.

Referring to Figure 4, an intersection is shown. In the embodiment of FIG. 4 , a first auxiliary traffic light 11 may be provided at the southeast corner of an intersection to provide an auxiliary signal to a vehicle making a right turn (R12). The first auxiliary traffic light 11 may be the auxiliary traffic light 100 illustrated in FIG. 3 described above, and may include a first light 111 at the bottom and a second light 112 at the top. A vehicle making a right turn (R12) must first pass through the first crosswalk (21), then turn at the intersection and pass through the second crosswalk (22). Accordingly, the auxiliary traffic light 11 may provide signals corresponding to signals of the first crosswalk 21 and the second crosswalk 22 .

In addition, in the following specification, for convenience, the first direction 31 is the direction from the south to the north of the intersection, the second direction 32 is the direction from the west to the east, and the north to south The direction is referred to as a third direction 33 and a direction from the east to the west is referred to as a fourth direction 34 . That is, the first auxiliary traffic light 11 is a traffic light corresponding to a vehicle entering the intersection in the first direction 31 making a right turn R12 and proceeding in the second direction 32 .

First, the signal server 200 acquires a signal of a first crosswalk 21 through which a vehicle entering an intersection in a first direction 31 passes. The signal of the first crosswalk 21 is a pedestrian signal, and may be a signal of the pedestrian traffic light 310 illustrated in FIG. 1, and may be a green light or a red light.

In addition, the signal server 200 turns the first light of the first auxiliary traffic light 11 green or red in response to the signal of the first crosswalk 21 . More specifically, the signal server 200 turns the first light red when the signal of the first crosswalk 21 is a green light, and turns the first light green when the signal of the first crosswalk 21 is a red light. equalize Accordingly, it is possible to indicate whether a vehicle passing through the first crosswalk 21 should stop or proceed according to a signal of the first crosswalk 21 .

In addition, the signal server 200 acquires a signal of a second crosswalk 22 through which a vehicle turns right at an intersection and proceeds in the second direction 32 . The signal of the second crosswalk 22 is a pedestrian signal, and may be a signal of the pedestrian traffic light 310 illustrated in FIG. 1 , and may be a green light or a red light.

In addition, the signal server 200 may turn the second light of the first auxiliary traffic light 11 green, red, or yellow in response to the signal of the second crosswalk 22 .

In addition, the signal server 200 turns the second light red when the signal of the second crosswalk 22 is a green light, and turns the second light on when the signal of the second crosswalk 22 is a red light. turn green Therefore, the driver can determine in advance whether to proceed with a right turn by recognizing the signal state of the second crosswalk 22 to be passed by turning right. For example, the driver of the vehicle making a right turn (R12) may determine to make a right turn only when both the first and second lights turn green.

According to an additional embodiment, the signal server 200 transmits the second light of the first auxiliary traffic light 11 in response to the signal of at least one main traffic light when the signal of the second crosswalk 22 is a red light. Additional equalization can be determined. At this time, additional lighting may be determined according to whether there is a possibility that the right-turning vehicle may collide with another vehicle flowing out from another outlet of the intersection.

That is, according to the embodiment of FIG. 4 , a vehicle entering the intersection in the first direction 31 and turning right (R12) has the main traffic light corresponding to the vehicle entering the intersection in the second direction 32 lit. When the straight ahead signal is turned on, there is a possibility of colliding with the corresponding straight ahead vehicle. In addition, a vehicle making a right turn (R12) may collide with a vehicle turning left when the main traffic light corresponding to the vehicle entering the intersection in the third direction (33) is in a left turn signal state.

To prevent this, when the signal of the second crosswalk is a red light, additional lighting may be determined by considering the lighting state of the main traffic light instead of simply turning the second light green. More specifically, the signal server 200, when the main traffic light corresponding to a vehicle passing through the second crosswalk 22 by going straight from the intersection in the second direction 32 is the straight ahead signal turned on, the first auxiliary It can be determined that the second light of the traffic light 11 is additionally equalized.

In addition, the signal server 200 displays the main traffic light corresponding to a vehicle entering the intersection in the third direction 33, turning left at the intersection and proceeding in the second direction 32 and passing through the second crosswalk 22. get lit state When the obtained lighting state is the left turn signal lighting, it may be determined that the second lamp of the first auxiliary signal lamp 11 is additionally equalized.

More specifically, the method of additional lighting may be to turn the second light of the auxiliary traffic light yellow, blinking yellow, or blinking red when there is a risk of collision with another vehicle after turning right at the intersection according to the signal of the main traffic light. At this time, the flickering light means flickering with a predetermined cycle. Hereinafter, although the method of additional lighting is limited to a yellow light for convenience of explanation, it is not necessarily limited thereto and may be substituted with a yellow blinking light or a red blinking light.

In an additional embodiment, the signal server 200 may obtain lane information of an intersection and determine an additional equalization scheme such as a second light by using the acquired lane information. At this time, if it is determined based on the lane information that the vehicle turning right (R12) is highly likely to collide with another vehicle going straight or turning left at another outlet of the intersection, the second light of the auxiliary traffic light provides a higher level of warning. can do. At this time, a warning of a higher level may be indicated by blinking red lights, and a warning of a lower level may be blinking yellow lights or yellow lights.

In a specific embodiment, when a vehicle making a right turn (R12) passes through a second crosswalk at the same time as a vehicle going straight or turning left at another outlet of an intersection, the possibility of vehicle collision is higher if the number of lanes is insufficient. In this case, the second light of the first auxiliary traffic light 11 may provide a warning of a higher level. More specifically, when the number of lanes corresponding to the second direction 32 of the second crosswalk 22 is less than or equal to a predetermined number, the second light is blinked in red, and if it exceeds the predetermined number, the second light is turned yellow. It can be lighted or yellow flashing. For example, when the number of lanes corresponding to the second direction 32 of the second crosswalk 22 is 2 or less, the second light is blinking red, and when the number of lanes is 3, the second light is turned yellow or It can flash yellow.

In another specific embodiment, when a vehicle going straight or turning left at another exit of an intersection has a higher probability of colliding with a vehicle turning right (R12) when the number of lanes decreases after passing the intersection, the second light of the auxiliary traffic light is more High-level warnings can be provided. More specifically, the signal server 200 corresponds to the number of lanes before passing the intersection with respect to the vehicle passing the second crosswalk 22 by going straight or turning left at the intersection to the second crosswalk 22 after passing the intersection. When the number of lanes in the second direction 32 is exceeded, additional lighting of the second light may be determined. For example, in relation to a vehicle going straight through the second crosswalk 22 in the second direction 32, if it is 5 one-way lanes before passing the intersection but 4 one-way lanes after passing the intersection, red blinking lights can be used. Unlike this, for a left-turning vehicle passing through the second crosswalk 22 in the second direction 32, yellow lights can be flashed if it is three-lane one-way before passing through the intersection but three-lane one-way after passing through the intersection.

Hereinafter, a method of displaying auxiliary traffic lights for various signal conditions will be described. For reference, the second auxiliary traffic light 12, the third auxiliary traffic light 13, and the fourth auxiliary traffic light 14 illustrated in FIGS. 5 to 12 have the same equalization scheme as that of the first auxiliary traffic light 11. can work as
