Abstract

The present invention relates to an intersection structure, and when a light path intersects a lane, a linear traffic island (A) of a certain length is provided along the center of the light path inside the intersection to prevent straight traffic flow on the lane and the light path at a distance from each side of the traffic island (A). Cross pedestrian crossings (C1, C2) are installed to cross the road, and crosswalking time allows straight and left turn traffic to bypass the linear traffic island counterclockwise, simplifying signal manifestation and allocating sufficient crosswalking time. Therefore, it is a linear rotary intersection structure that ensures the safety of crosswalks and improves safety and operation of intersections by taking advantage of rotary and signal intersections.

Description

Linear Rotary Intersection}

The present invention relates to an intersection structure in which the optical paths 1 and 2 meet the paths 3 and 4, and more specifically, a central separator-shaped linear traffic island (A) cut in the direction of the optical paths (1, 2) at the center of the intersection. To prevent straight traffic flow on the lanes (3,4), and install pedestrian crossings (C1, C2) crossing the optical paths (1, 2) at a distance from each side of the traffic island (A), The present invention relates to a linear rotary intersection structure in which a traffic flow on a lane turns the linear traffic island A in a counterclockwise direction to go straight or turn left.

In general, when an optical path that handles a large amount of traffic controls an intersection resulting from a small lane with a small traffic volume, the green path is assigned the maximum green signal and the small green signal is assigned to the optical path in order to increase the efficiency of the intersection. Inadequate consideration of cross-walking time leads to inefficiency in crossroads communication and risk of traffic accidents.

FIG. 5 shows the geometry of a typical crossroad intersection where a conventional light path and a lane meet, and are composed of light path access paths 1 and 2 and lane access paths 3 and 4 to the east, west, south, and north of the intersection, respectively.

The right side of the median separator D1 of the east side optical path access path 1 of FIG. 5 is composed of the access roads E11, E12, E13, and E14, and the left side is composed of the access roads X11, X12, X13, and X14. You may leave the road ahead. The leftmost lane E11 is a left turn lane and the rightmost lane E14 is a right turn lane. In addition, when a pedestrian crosses a crosswalk C1 so that a pedestrian can cross the access road 1, a stop line S1 is placed on the access roads E11, E12, E13, and E14 for safe crossing.

West side light path 2 consists of access lanes E21, E22, E23, and E24 on the right side of the median D2, and the left side consists of X21, X22, X23, and X24 on the left, but depending on the traffic volume, Can be placed. It is common to use the leftmost lane E21 as the left turn lane and the rightmost lane E24 as the right turn lane. In addition, if a pedestrian crosses a crosswalk C2 so that a pedestrian can cross the access road 2, a stop line S2 is placed on the driveways E21, E22, E23, and E24 for safe crossing.

The lane approach 3 on the south side consists of the driveways E31 and E32 and the driveways X31 and X32. However, in the case of low traffic, it may consist of one driveway and one driveway. In addition, a pedestrian crossing C3 is provided so that pedestrians can cross the access road 3, and a stop line S3 is placed for the safety of the pedestrian crossing.

On the other hand, the access road 4 on the north side is composed of access roads E41 and E42 and exit roads X41 and X42. However, in the case of low traffic, it may consist of one access road and one exit road. In addition, a pedestrian crossing C4 is placed so that pedestrians can cross the access road 4, and a stop line S4 is placed for the safety of the crossing.

FIG. 6 shows a traffic flow flowing in the crossroads of FIG. 5 according to the signal manifestation. In the first prefecture, the left turn of the first phase and the left turn of the two of the lightpath access paths are simultaneously performed. As a signal to allow a straight vehicle on the optical path, the pedestrian crosses lanes 3 and 4 using a crosswalk C3 on three lanes and a crosswalk C4 on four lanes. In the third prefecture, the traffic flows in the lane access road 3 receive a simultaneous signal and go straight or turn left. Incoming traffic flows straight or left after receiving simultaneous signal, and at the same time, crosses the optical path access path 2 using the crosswalk C2 on the optical path access path 2.

Under the conventional signal system, the traffic volume on the lane access road is not as large as that of the optical path, so the green light is allocated to the three and four prefectures and the green signals are allocated to the one and two prefectures. The lack of crosswalking time leads to the inefficiency of the intersection operation and the risk of traffic accidents. In addition, the four-way signal system was adopted to give all four access paths the left turn protected by signals, and the signal waiting time became longer as the signal period became longer.

When the four-way intersection where the light path meets the path is operated by the above-mentioned four-way signal system, there is a shortage of crosswalking time that crosses the light path and a long waiting time.

The purpose of the present invention is to reduce the signal waiting time by shortening the signal period by operating the intersection of the optical path and the lane as a two-state signal.

Another object of the present invention is to ensure the safety of the optical path crossing by giving a sufficient optical path crossing time at the intersection.

Still another object of the present invention is to provide convenience of traffic by allowing left and right turns and U turns of any traffic at the intersection.
