Abstract

The present invention adds an auxiliary left turning lane (L3) serving as a variable lane that can turn left to the left turning lane (L1) and the opposite lane (L2) adjacent to the intersection, the left turning lane is two lanes of the left turning lane, the auxiliary left turning lane is 1 The left turn change lane structure of the intersection, characterized in that made to turn left in the lane.

Therefore, when a pedestrian makes a left turn after the crosswalk at the front of a vehicle that has stopped at the driving line, he makes a plurality of left turn lanes using the auxiliary left turn lanes beyond the center line, so that the number of vehicles that can turn left in the left turn lane without additional lane extension is 2 Increase more than twice.

Description

Variable car lane structure for left turn of cross road}

The present invention relates to a left turn change lane structure of an intersection where a left turn lane can be used as a second lane by adding an auxiliary left turn lane serving as a variable lane that can turn left to an opposite lane adjacent to a left turn lane of an intersection.

In general, after the vehicle is turned off at the intersection, the left turn signal is turned on and the left turn vehicle is turned to the left at this time before the straight turn starts again. This is waiting in the first lane as shown in FIG. However, since the left turn lane is mostly one lane, the number of possible left turns per hour is limited, and when the signal is short, the left turn vehicle may receive two or more signals, causing traffic jams.

The present invention is to solve this problem, an object of the present invention is to increase the number of vehicles that can turn left by variably extending the left turn lane by allocating a part of the left turn lane to the first lane of the opposite lane near the end of the intersection.

To this end, the present invention additionally sets a part of the first lane of the opposite lane adjacent to the left turn lane of the intersection as a left turn lane.

2 is a lane structure diagram of the present invention.

Explanation of symbols for the main parts of the drawings

L1; 1 lane L0; center line L2; opposite lane L3; secondary left turn lane

That is, the present invention is to provide a left turn change lane structure of the intersection partitioning the auxiliary left turn lanes forming a part of the opposite lane near the end of the intersection of the left turn lane of the intersection.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a plan view of the present invention, in which an auxiliary left turning lane L3 serving as a variable lane capable of turning left is added to a left turning lane L1 and an adjacent lane L2 adjacent to an intersection, and when a walking light is red when the walking light is red ( When there is no pedestrian traffic, when separate traffic lights are operated), the driver moves from the first vehicle to the auxiliary left turn lane and turns into multiple turns lanes, and the left turn lane is made into two lanes of the left turn lane, and the auxiliary left turn lane is simultaneously made to make one turn. (L0) is the center line. In the above example, the left turn lane is illustrated as one lane, but when two lanes are left turn lanes, additionally, the left turn lane provides an effect of increasing one left turn lane. The auxiliary left turn lane L3 may be exemplified as having a dashed line shape.

According to the present invention, when the vehicle straight traffic light turns into a stop signal and then the pedestrian traffic light turns green, the pedestrian crosses the crosswalk, and when the pedestrian traffic light turns red, the auxiliary left turn lane ( If you go through L3) and wait for a left turn through two lanes and turn to a left turn signal, you will turn left simultaneously in two lanes. In this case, the left turn lane is extended from the one lane to the first lane of the adjacent opposite lane to the auxiliary left turn lane, thereby increasing the number of left turn lanes to two lanes, thereby increasing the number of left turn vehicles more than twice during the same left turn signal period. . Of course, the length of the auxiliary left turn lane L3 may be divided in consideration of the traffic volume of the road. Specifically, when the pedestrian traffic light turns from blue light to red light, the left turn vehicle travels slightly in the form of the illustrated vehicle (①, ② ...) and moves to the position of the vehicle (a1, a2) to make two left lanes. In this state, when the vehicle turns to the left turn signal, the vehicle is divided into two lanes after the left turn and turns left to increase the number of vehicles that turn left per unit time. That is, for example, the vehicle a1 turns left in the two lanes to the vehicle b1 and the vehicle a2 turns left to the vehicle b2 to show that the vehicle turns left in the one lane. Therefore, the left turn guide line (Lr) may be further drawn on the road surface so that beginners can turn left from the first lane to the second lane and turn left from the auxiliary left turn lane (L3) to the first lane. Preferred examples of the left turn guide line Lr are separated from the existing lines in the form of double-dotted lines. Of course, where the crosswalk is not at the intersection (for example, where there is an underground walkway), the left turn vehicle and the existing left turn lane are used. Wait in turn and turn left.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention prioritizes a straight signal at an intersection where the traffic is frequently communicated, so that the time of the left turning vehicle is shortened to solve the interference of the driving vehicle due to the waiting of the left turning vehicle. After walking through the sidewalk, when the pedestrian lights turn red (when there is no pedestrian traffic, separate lights operate), make a left turn lane in multiple lanes using the auxiliary left turn lane, and when you turn left, turn left into two lanes at the same time. Increases the number of vehicles that can turn left in a left turn lane more than twice without additional lane expansion.
