Description

One-stop two-level crossing system

The present invention relates to a one-stop intersection system, and more particularly, to a three-dimensional intersection system capable of performing intersection traffic with a single signal.

Every year, traffic jams on urban and urban outskirts and on average road speeds incur huge traffic congestion costs, causing massive national losses. Traffic congestion cost refers to the total cost incurred such as loss of time value caused by driving the car below the normal speed due to traffic congestion and increase of vehicle operation cost. Congestion costs are calculated and announced.In 1996, the national traffic congestion cost amounted to about 15.92 trillion won, and the national traffic congestion cost in 1997 amounted to about 18.337 trillion won. have. As such, the enormous traffic congestion cost that hinders national development should be reduced through active and reasonable investment in transportation facilities, traffic demand management, efficient operation of existing facilities, and active transportation policies that prioritize public transportation. Increasing traffic handling capacity can be an option.

In general, the traffic handling capability of the road, as shown in Figure 1, the vehicle 11, 12 proceeding from south to north and the vehicle (21, 22) proceeding from each other in the north and south proceeding in the east It can be seen that the capacity is determined at the intersection 50 where vehicles coming from four directions, such as vehicles 31 and 32 and cars 41 and 42 proceeding from east to west, are divided in a straight direction and a left turn direction, respectively. At most intersections 50, traffic lights (not shown) are installed in each direction to give a straight and left turn signal, so that the vehicle can communicate. However, when a lot of vehicles are crowded at once, it is inevitable that traffic jams occur. do.

In order to solve the congestion that occurs at the intersection like this, by installing a straight elevated roadway on the intersection or a straight underground roadway to make the intersection three-dimensional, the bottleneck does not occur at the intersection to improve the road traffic ability. The way to make it is proposed. Intersections installed on highways, public roads, and automobile roads have low land prices and are easy to purchase, making it possible to use non-stop clover- or diamond-shaped three-way intersections using 10,000㎡-15,000㎡. Intersections in the city are not possible this way, the intersection is required to achieve smooth communication between pedestrians and vehicles in the city.

It is an object of the present invention to provide a one-stop solid-intersection system for resolving vehicle congestion due to signal waiting at an intersection.

Another object of the present invention is to provide a one-stop cross-sectional system that can reduce the waste of fuel due to signal waiting of the vehicle at the intersection.

In order to achieve the above object, the three-dimensional crossover system according to the present invention allows the first road to go straight to the third road forming ∠180 ° and to the fourth road making 270 ° with the first road. With overpass, installed,

An underground roadway installed to allow a left turn on the second road making a 90 ° angle with the first road and a left turn on the fourth road,

A plan view installed so that the straight vehicle on the second road, the straight vehicle on the fourth road, and the straight vehicle and the left-turning vehicle on the third road can alternately pass signals,

It is characterized by including a crosswalk installed on the plan road of each road.

Detailed features of the three-dimensional intersection system according to the present invention in the direction of the outermost lane of the first road from the outermost lane of the second road, so that the underground road can turn left in the direction of the first road on the second road, on the fourth road It is a point provided in the direction of the outermost lane of the 3rd road from the outermost lane of the 4th road so that it may turn left to the 2nd road. However, it is possible to install from three lanes to three lanes in facilities.

FIG. 7 is an exemplary view illustrating a straight ahead of a south-north vehicle in a state in which the west side vehicle stops.

Hereinafter, with reference to the accompanying drawings will be described the structure of the three-dimensional intersection system according to the present invention and the vehicle progress method according to the structure. Figure 2 is an exemplary view showing the overall configuration of a three-dimensional cross-sectional system according to the present invention. The indications of the north, south, west, and north indicated in this exemplary diagram are shown for example to facilitate understanding of the configuration of the intersection system, and do not represent the absolute direction of the configuration. As shown, the three-dimensional intersection according to the present invention and the overpass road installed to enable the left-hand drive in the south direction and the straight vehicle from the east direction to the west direction, so as to turn left in the north direction in the east direction or south direction in the west direction Including underground left turn lanes, vehicles going south to north or north to south, floor plans for vehicles going west to east and turning left to north, and crosswalks on each road It can be seen.

A method of using an intersection according to the present invention will be described separately from the vehicle traveling method in each direction.

First, FIG. 3 shows a straight turn to the west and a left turn to the south using an overpass in the east direction. Therefore, it can be seen that it is possible to proceed without receiving a separate vehicle control signal.

4a to 4b show a vehicle traveling method in the north, and FIG. 4a shows a straight road from north to south using a plan view road, and FIG. 4b shows a left turn to east using an underground roadway. Therefore, in the left turn, it is not necessary to receive a separate vehicle control signal.

5A to 5B show a vehicle traveling method in a south direction, and FIG. 5A shows a straight road from south to north using a plan view road, and FIG. 5B shows a left turn in a west direction using an underground roadway. As in the case of FIG. 4B, in the case of the left turn, a separate vehicle control signal does not need to be received.

On the other hand, Figure 6 shows a state to go straight and turn left by receiving a simultaneous signal using a plan view in the west direction. It should be noted that when the west side vehicle receives a simultaneous straight and left turn signal, the straight vehicle in the south side and the north side will stop. At this time, pedestrians can cross by using a crosswalk installed on the south road and the north road.

When the simultaneous signal of the vehicle toward the west is changed to red light, as shown in FIG. 7, the vehicle traveling in the west direction is stopped, and the straight signal for the south → north, north → south straight vehicles (green) light) comes on. Therefore, pedestrians can cross using pedestrian crossings on the east and west roads, turn north to east, turn south to west and go east to west and turn left. It can go freely regardless.

At this time, it should be noted that each crosswalk should be installed on the underground road under the overpass so that pedestrians can walk safely. Underground roads can be selected among 3 and 4 lanes and the width can be adjusted arbitrarily. You can turn left using. It is preferable that the installation direction is provided in the leftmost lane direction from the rightmost lane. That is, the underground roadway for turning left from the north direction to the east direction is installed in the direction of the outer lane of the east direction from the rightmost lane of the north road, and the left side road turning left toward the west direction from the south road is located outside the west lane from the rightmost lane of the south road. It would be desirable to install in the lane direction. In the above description, a separate description of the right-turn vehicle is omitted. This is because in general, a right turn vehicle can safely turn right after seeing the flow of pedestrians and straight vehicles in a crosswalk.

In the above description, the one-way four-lane example is taken as an example, but only the intersection portion of the two-lane or three-lane road may be implemented when the intersection system shown in the present invention is applied, which is also included in the application of the present invention. It can be said.

As described above, the three-dimensional crossroad system according to the present invention controls a three-lane straight vehicle by using a single signal, a left-turning vehicle in two directions using an underground roadway, and using an overpass in one direction It can handle the straight ahead and left turn to prevent congestion of the vehicle generated while waiting for the signal, and has the effect of preventing the consumption of fuel and pollution of the environment generated during the waiting for the signal.
