Embodiment 1

[0024] Such as figure 1 As shown, a traffic system without traffic lights at a crossroad is characterized in that: a longitudinal lane z on the ground and a transverse lane h that is cross-staggered with the longitudinal lane are arranged at the intersection, and the transverse lane h is the sky above the ground or below the ground Lane, right-turning lane w is all provided on the limit of 4 intersections of intersection, and the place far away from intersection 50 meters on described longitudinal lane and transverse lane each all has U-turn lane t. When two intersections are relatively close apart, there may be no U-turn lane or only one U-turn lane between them.

[0025] A vehicle turning left is achieved by first going straight, then making a U-turn, and finally turning right.

[0026] In the technical scheme of the traffic system without traffic lights at the above crossroads, the horizontal lane h at the crossroads is an upwardly convex arc bridge, the longitudinal lane ...

Embodiment 2

[0034] This embodiment is basically the same as the first embodiment above, the difference is that in the above-mentioned technical scheme of the traffic system without traffic lights at the intersection, there is a U-turn lane t within 200 meters from the intersection on the longitudinal lane z, but there is no horizontal lane h, then The left-turning vehicle on the horizontal lane h does not go straight through the intersection, but first passes through the right-turning lane, enters the longitudinal lane, then changes lanes and enters the U-turn lane, and then drives towards the target direction after turning around. When there are not many vehicles, this scheme is also feasible.

Abstract

The invention provides a crossroad traffic system without traffic lights. The system is characterized in that: the crossroad is provided with a ground longitudinal lane (z) and a transverse lane (h) in cross staggered arrangement to the longitudinal lane. The transverse lane (h) is the lane over or under the ground. Edges of four junctions at the crossroad are all provided with right turn lanes (w). The places that are at least 1m, generally 50m, away from the crossroad on the longitudinal lane and the transverse lane are respectively provided with U-turn turning lanes (t). A left turn vehicle firstly goes straight to pass the crossroad and enters a preliminary U-turn lane in advance, then realizes U-turn at a U-turn turning lane, and finally enters a right turn lane and drives toward a target direction, thus realizing left turn.

Description

technical field [0001] The invention relates to a road traffic system, in particular to a traffic system without traffic lights at a crossroad. Background technique [0002] At present, there are many kinds of traffic systems without traffic lights at intersections reported, each with advantages and disadvantages, but generally there are disadvantages such as large space occupation, complex structure, high cost, and large engineering. Contents of the invention [0003] The present invention provides a traffic system without traffic lights at crossroads which is unobstructed in all directions, takes up less space, has a relatively simple structure, is low in cost, and has a small project size. It solves the problems of traffic jams at crossroads, frequent traffic accidents, and the like. [0004] A traffic system without traffic lights at a crossroad is characterized in that: a longitudinal lane z on the ground and a transverse lane h that is cross-staggered with the longit...
