Problems solved by technology

[0004] At present, the disadvantage of the access method adopted by branch roads and trunk roads on some roads is: the sequence of access is not proper, resulting in two conflicts of left-turn traffic flow on the trunk road
Therefore, it is easy to cause traffic accidents at the conflict point; it also affects the smoothness here, and it is easy to cause traffic jams

Embodiment 1

[0015] A branch road and arterial road access method, on the side road 41 of the arterial road 4 connected to the arterial road intersection 1 that enters the arterial road intersection 1, connects to the arterial road intersection 1 for driving away

[0016] The left turn of the vehicle enters the road 2, and the access for the left turn of the vehicle entering the arterial road intersection 1 is inserted on the side road 42 of the arterial road 4 connecting the arterial road intersection 1 and leaving the arterial road intersection 1 Road 3, and. Left-turn access road 3 for vehicles entering arterial road intersection 1 is at a greater distance from arterial road intersection 1 than left-turn access road 2 for vehicles leaving arterial road intersection 1 1 distance

Embodiment 2

[0018] A kind of branch arterial road that is used for branch road and arterial road access method, comprises: arterial road intersection 1, on the side road 41 that enters arterial road intersection 1 of arterial road 4, be provided with for driving away from arterial road The left-turn access road 2 of the road intersection 1 vehicle is provided with a left-turn access road 3 for entering the arterial road intersection 1 vehicle on the side road 42 of the arterial road 4 leaving the arterial road intersection 1, Also, the distance from the left-turn access road 3 for vehicles entering the arterial road intersection 1 to the arterial road intersection 1 is greater than the distance from the left-turn access road 2 for vehicles leaving the arterial road intersection 1 to the arterial road Intersection 1 distance.

Abstract

A branch road and arterial road access method, on the side road of the arterial road that connects arterial road intersection and enters the arterial road intersection, access the left-turn access road for vehicles leaving the arterial road intersection, and connect The access road on the side of the arterial road away from the arterial road intersection for the left turn of vehicles entering the arterial road intersection and for the left turn of vehicles entering the arterial road intersection The distance from the access road to the arterial road intersection is greater than the distance from the access road to the arterial road intersection for left turns for vehicles leaving the arterial road intersection. By improving the way of road access, the degree of interference of vehicles entering the branch road on the main road is reduced, and the traffic congestion on the urban arterial road is alleviated. By improving the way of accessing the road, it can provide drivers with favorable ride conditions and improve the driver's ride safety. The number of conflict points on the road can be reduced, which is beneficial to driving safety.

Description

technical field [0001] The invention relates to a method for connecting a branch road on a trunk road connected to an intersection of a trunk road and the road thereof, in particular to a method for connecting a branch road and a trunk road and the branch road to the trunk road. Background technique [0002] Intersections include at-grade intersections, interchanged interchanges, and split interchanges. According to data, 1 / 3 of accidents on the road occur at intersections. Therefore, it is very meaningful for traffic safety to do a good job in the reconstruction design of the intersection black spot. [0003] For the reconstruction of intersections, it is generally necessary to do a good job including reducing conflict points between vehicles and pedestrians, improving traffic capacity, and improving the quality of information provided. The improvement technology of the intersection includes the improvement of the section of the intersection and the intersection itself (s...
