Embodiment Construction

[0043] Below, the present invention will be further described in conjunction with the accompanying drawings.

[0044] The present invention is a kind of method of the electronic program-controlled left-turn time lane of city crossroads, take the 8 lanes of A, B crossroads as an example. figure 1 Shown is a schematic diagram of the structure of road A at the intersection, including the time box facilities set on the road surface at the intersection of road A, and the information lamp group automatically controlled by the electronic program. The present invention constructs an electronic program-controlled time box on the road surface at the intersection of roads A and B, and sets box boundary marking lines 15, 15a at both ends of the box, that is, 135 meters away from the central point of the intersection, and on the straight lane 13 13a, 115 meters away from the center point of the intersection, set left-turn curve marking lines 14, 14a; on both sides of road A, 115 meters awa...

Abstract

The invention provides an electronic program control method for a left-turning time lane at an urban intersection. A time box system is established at the intersection, and a traffic information lamp group is controlled by writing a program for automatically controlling the information lamp group through an electronic program, so that a left-turning vehicle queue in a time box completes left-turning travel in all time of a straight-going vehicle queue which runs in the box. The method has the advantages that (1) straight-going time is changed into or the same as left-turning time through an automatic control function of the electronic program, so that the left-turning time lane which can replace a left-turning flyover is constructed, the left-turning vehicle queue and the straight-going vehicle queue can synchronously cross the intersection without interfering with each other, and the world problem of urban traffic congestion caused by intersection congestion is effectively solved; and (2) the left-turning time lane has the function of the left-turning flyover, so that the number of the left-turning flyovers constructed in numerous cities can be reduced, and great economic and social benefits are achieved.

Description

technical field [0001] The invention relates to a method for electronically program-controlled urban intersections, in particular to a method for electronically program-controlled left-turn time lanes at intersections. Background technique [0002] Today's world has entered the age of electronic information, and society is developing at an unprecedented speed. Humans can even take rockets, land on the moon, and explore Mars. However, in serious contrast to this, in China and even in the developed countries of the world, facing the world problem of urban traffic congestion, they are helpless and trapped in a predicament. Congestion has become a lingering trouble in many cities, and has seriously affected the development of cities and people's lives. The inventor realizes through in-depth study that will solve the problem of traffic congestion, must walk in three steps: [0003] The first step is to find the crux of the congestion. The inventor finds through observation an...
