Description

Traffic guidance structure that provides smooth traffic at intersections and traffic control method accordingly

The present invention relates to a traffic guidance structure for providing a smooth traffic to an intersection, and in particular, a traffic guidance suitable for other terrain and space to guide the traffic to pass through the intersection smoothly and without blockage by any traffic jam. It's about structure.

For example, US Patent No. 4,986,692, registered to Weirung on November 22, 1991, is a smooth road at the intersection of the main road and the branch road, which is called "intersection structure for traffic control" (hereinafter referred to as "quoting patent"). There is a patent close to a solution that provides a passage.

FIG. 1 of the cited patent shows a main rod AB extending from north to south for the right passage and two branch rods CD, EF extending from each other in the east. The branch rods CD, EF are connected to the main rod AB at the right corner and the intersection point is flat. The safety zones (I, J) are located at the intersection in a horizontal manner with the main rod where the longitudinal axis of the safety zone divides the main rod equally, which prevents cross traffic on the branch rod. Circular bypasses (ab, cd, df, gh) are provided on both sides of the main road close to the branch road. In order to avoid collision of vehicles and motorcycles at the intersection, underground passages for motorcycles or pedestrians are constructed below the intersection of circular roundabouts (o, p, q, r, s, t, u, v).

The main road AB has four lanes and arrows 1, 2, 3, and 4 indicating the direction of travel on these lanes. Dotted lines, underlined lines and numbers indicate lanes for the vehicle. It is clear that in lanes 2 and 3 on both sides, the vehicle can go straight through the intersection without interruption, but vehicles in these lanes may be branch roads (CDs) or other branch roads unless they change lanes to the outside lane. You cannot turn right with (EF). The vehicle may also not make a left turn or U-Turn unless it passes a tunnel or overpass through a round bypass (cd) or other bypass (gh). In lanes 3 and 4, the vehicle must go to a round bypass (ef) or another bypass (ab) to make a left turn or a U-turn.

The branch rod CD has two lanes 5 and 6. A vehicle in the lane 5 may turn right onto the main road AB but cannot turn left or go straight across the intersection because of the safety zones 1 and J. The vehicle must go through the tunnel or overpass to the roundabout cd and then turn right onto the road D or enter the main road AB. The vehicle in lane 6 must similarly go to a round bypass ab to make a left turn or a U-turn.

In the cited patent, the circular bypass roads (ab, cd, ef, gh) are used to avoid traffic jams at the intersection of the branch roads (CD, EF) and the main road (B) and at the intersection. Used to remove The following drawbacks are introduced in the cited patents.

1. The circular bypass roads (ab, cd, ef, gh) must have a sufficiently large bend and enough lanes for the vehicle to safely drive on the bypass roads (ab, cd, ef, gh). That is, the intersection of the main rod and the branch rod should have a sufficient width even if there is no building or structure in the area where the circular bypass and the branch rod are located. Such circular bypasses are not suitable for small intersections and intersections with many buildings around them.

2. Since the safety zones I and J are used to prevent cross traffic on the branch road, vehicles passing through the branch road must use the circular bypass to cross the intersection with the main road. Since the circular bypass and the width of the branch road and the traffic state are not always the same, the circular bypass causes traffic jams in the ramp and rather hinders the smooth passage to the branch road. That is, the safety zone that prevents traffic on the branch road by crossing the main road in a straight line can solve the traffic jam on the main road at the intersection with the branch road, but does not solve the traffic jam on the branch road. can not do it.

3. The structure of tunnels or bridges on both sides of the branch road and intersection and the main bypass close to the round bypass and intersection is technically complex and causes the length to increase and decrease repeatedly. Moreover, high construction costs are required.

Therefore, the main object of the present invention is to provide a traffic guidance structure only at intersections in a limited space, where the traffic flow can be smoothly guided by simply overpasses or underground tunnels.

Another object of the present invention is to provide a traffic guidance structure at an intersection so that vehicles on the main road and branch roads run in a straight line when the vehicle passes the intersection, and by means of a circular bypass designed inappropriately by the structure. It is to prevent traffic jams in the generated branch roads.

And near each side of the first bridge B in the branch rod ML, there are each second bridge A and a third bridge C standing parallel on the main road JK. All of the bridges A, B and C have tunnels under the bridge. Underpass I is only built for pedestrians. And in the second embodiment, as shown in FIG. 2, the first underground tunnel B1 extends in a direction parallel to the branch rod ML and is the intersection of the branch rod ML and the main rod JK. The second and third underground tunnels (A1, C1) are constructed parallel to the main rod (JK) in the lower portion near each side of the first underground tunnel (B1) of the branch rod ML. Overpasses (W, X, Y, Z) are only built for pedestrians. The turning zone (G, F) is between the two access roads of the underground tunnels (A1, C1) to form secondary and tertiary turning zones on the second and third underground tunnels (A1, C1) on the main road (JK), respectively. It is provided on the main rod (JK) to be located in the upper middle of the. Another turning zone (G1, F1) is the first underground tunnel (B1) so as not to interfere with the main rod (JK) to form two primary turning zones above the first underground tunnel (B1) in the branch rod (ML). Is provided in the branch rod ML so as to be positioned midway over the top of each entrance. Both main roads JK and branch roads ML are provided with a boundary line H (see FIGS. 3 and 5) such that the two roads JK and ML keep the vehicle away from pedestrians. The stairs of the underpass I and the bridges W, X, Y, Z can also be replaced by escalators.
