Problems solved by technology

Article 51 (2) of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: "Those who are about to enter the roundabout should let the motor vehicles already in the intersection go first;" the traffic regulations on the roundabout are too simple, Vehicles cannot be effectively guided through roundabouts, especially large roundabouts with four forks or more, where there are many passing subjects and a large number of lanes, which can easily cause traffic chaos during peak traffic hours

Embodiment 1

[0051] Such as figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the traffic diversion system for the roundabout crossing includes at least two roads, the roads intersect to form an intersection, each of the roads is provided with a pedestrian crossing 1 in front of the stop line on the entrance side of the intersection, so The above-mentioned road is also provided with a boundary line 2 corresponding to the opposite carriageway, and the boundary line 2 of the opposite carriageway includes not only the marking line in the traditional sense, but also the isolation zone formed by the isolation fence, isolation pier or flowers and plants. The technical solution is also within the protection scope of this patent. Described road surface is positioned at the outer side of described opposing roadway dividing line 2 and is provided with non-motorized vehicle lane 3, is also provided with motor vehicle between described opposing roadway dividing line 2 and described non-motor...

Embodiment 2

[0073] Such as figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the difference between the present embodiment and the first embodiment is that the two roads intersect to form the intersection, and in the intersection there is a two-way traffic and intersection straight guide lane 17 set at the intersection, and the road At least one straight-going guide lane 18 is arranged between the dividing line 2 of the opposite carriageway and the shared guide lane 4 for turning right and entering the roundabout. The straight-going guiding lane 17 at the intersection is connected and arranged, and the straight-going guiding arrow mark 19 is arranged on the road surface in the straight-going guiding lane 18 of the road. The guide lanes in the intersection are similar to those in Embodiment 1, and the lanes can be appropriately increased or decreased according to the size of the intersection.

[0074] The surface of each lane is correspondingly provided with driving guide marki...

Embodiment 3

[0090] Such as image 3 , Figure 5 , Figure 6 and Figure 7 As shown, the present embodiment has the following differences from the second embodiment. Difference one: the present embodiment is on one of the roads that intersect, specifically on the direct guide lane 18 of the road and the right turn and entering the roundabout. Between the lanes 4, there is also a guide lane 27 for going straight and entering the roundabout. The road surface in the guide lane 27 for going straight and entering the roundabout is provided with an arrow marking 28 for going straight and entering the roundabout. The road traffic sign board 10 is provided with the said lane guide sign 20 corresponding to the guide lane 27 for going straight and entering the roundabout. Arrow sign 29.

[0091] Difference 2: In this embodiment, on another said road that intersects, specifically between said road straight-going guide lane 18 and said right-turning and turning-in roundabout shared guide lane 4, s...

Abstract

The invention discloses a traffic diversion system for a roundabout intersection. The system is characterized in that a straight-going, right-turning and roundabout-entering combined guide lane for motor vehicles or / and a right-turning and roundabout-entering combined guide lane are sequentially arranged from a boundary line of an opposite roadway to a non-motor vehicle lane; a non-motor vehicle circulating lane and a circulating and roundabout-leaving combined guide lane for at least one motor vehicle are arranged in the intersection; circular stop lines corresponding to the road are arrangedon the circulating lane crossing non-motor vehicles and the circulating and roundabout-leaving combine guide lane; and a road traffic sign board and a traffic signal lamp used for indicating the running of vehicles are correspondingly arranged on one side of the intersection at which vehicles enter. The invention further discloses an expanding application method of the system. The method can realize the 'roundabout+straight' traffic mode, reduce the traffic phase, can be operated in different periods, has large traffic capacity and short traffic period, avoids unnecessary detention of vehicles at intersections, and has positive effects in all aspects.

Description

technical field [0001] The invention relates to the field of traffic diversion technology, in particular to a traffic diversion system for roundabout crossings, and also relates to an extended application method of the system. Background technique [0002] With the growth of car ownership, road traffic pressure also increases. At present, the most commonly used phase settings for traffic at common road intersections are: 1. Go straight on this road; 2. Turn left on this road; 3. Go straight on the crossing; 4. Turn left on the crossing, a total of four clearance phases. The above-mentioned vehicle diversion method is only suitable for road intersections with small traffic volumes. When the traffic volume is large, the road intersections of the above-mentioned diversion methods will cause a large amount of vehicles to stay at the intersection and a long time to stay. In response to the above phenomena, roundabouts were gradually developed and used. Article 51 (2) of the "Re...
