Example Embodiment

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] The first embodiment of the present invention is composed of two roads B and C forming a straight line, a road A intersecting with the two roads, and an intersection D, mainly in the two roads B and C forming a straight line. Set up outer guide islands B on C and near the intersection D 1 , inner guide island B 2 and Bypass B 1，2 , the outer guide island C 1 , inner guide island C 2 and detour C 1、2 , and connecting the two inner guide islands B 2 ,, C 2 and draw a closed loop line D in the middle of the intersection D 2 , as shown in Figure 1, where:

[0016] Outer guide island B 1 、C 1 and inner guide island B 2 、C 2 They are respectively set in the middle of roads B and C near both sides of the intersection D (where the road surface is partially widened), and the outer guide island B 1 、C 1 It is in the shape of "concave arc fa...

Abstract

The invention relates to a plat t-shaped cross road traffic overall arrangement that is made up of two roads on the same line, a road crossing the two roads, and a way crossing. The main feature is set out oriented island, inner oriented island and circumambulated way and break car line that connects the two islands. A closing loop is curved in center of the way crossing. Thus the traffic time is shortened and traffic jam would be decreased.

Description

technical field [0001] The invention relates to a traffic layout of a plane T-shaped intersection, in particular to a traffic layout of a plane T-shaped intersection of urban roads. Background technique [0002] At present, motor vehicles and non-motor vehicles on urban roads are most seriously congested at T-shaped intersections and cross-shaped intersections. Existing T-shaped intersections are usually used: one is multi-phase signal lights, which open all roads in sequence, but prolongs the waiting time for vehicles to stop; the other is two-phase signal lights, which go straight and turn left at the same Passing at the same time when the signal is on, shortens the time for vehicles to stop and wait. However, conflicts are likely to occur between straight-going and left-turning vehicles; The required passage time is longer than that required by non-motor vehicle traffic, and the distribution of passage time is unreasonable. In addition, motor vehicles and non-motor vehic...
