TRAFFIC-LIGHT-FREE OVERPASS AT INTERSECTION

A traffic-light-free overpass at intersections has roads arranged as follows: arranging from west to east a straight lane for ground-level motor vehicles, a straight lane for ground-level non-motor vehicles and pedestrians, a left-turn lane for ground-level motor vehicles, a right-turn lane for elevated motor vehicles; arranging from east to west a straight lane for elevated motor vehicles, a straight lane for elevated non-motor vehicles and pedestrians, a left-turn lane for elevated motor vehicles, a right-turn lane for ground-level motor vehicles; arranging from south to north a straight lane for underground motor vehicles, a straight lane for underground non-motor vehicles and pedestrians, a right-turn lane for elevated motor vehicles, a left-turn lane for elevated motor vehicles, a section of straight lane for elevated motor vehicles, a left-U-turn lane for underground motor vehicles; arranging from north to south a straight lane for underground motor vehicles, a straight lane for underground non-motor vehicles and pedestrians, a left-turn lane for ground-level motor vehicles, a right-turn lane for ground-level motor vehicles, and a left-U-turn lane for underground motor vehicles. The traffic-light-free overpass at intersections of this functional invention is built on the established roads rather than the new lands, which saves the capital investment, and has a complete function, where this overpass has exclusive lanes in each direction without crossings. The scale of the overpass is 5 times less than those in the market, which is beneficial to the rational use of the metropolitan tracks and traffic resources.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This functional invention relates to a multi-level traffic system architecture for traffic flow crossing intersections, and more particularly to a traffic-light-free overpass at intersections.

2. Description of Related Art

Currently, the overpass as disclosed in the prior arts has the deficiencies including a large scale, complicated layout, high construction costs and incomplete functions, requires the assistance of the traffic lights to control the traffic flow, fails to functionally meet the needs of motor vehicles making a left turn and U-turn and the needs of pedestrians and non-motor vehicles crossing the roads without obstacle, which consequently incurs the unsmooth traffic flow and affects the life quality of civil residents.

SUMMARY OF THE INVENTION

An objective of this functional invention is to provide a traffic-light-free overpass at intersections, which has a reasonable arrangement and achieves the easy access and smooth traffic flow, thereby solving the problems existing in the prior arts.

The technical issue to be solved by this functional invention is realized by the following technical solution. This functional invention includes a traffic-light-free overpass at intersections, which is characterized by that this overpass has roads arranged as follows:

(1) arranging from west to east:

a straight lane for ground-level motor vehicles (motorized vehicles), and a straight lane for ground-level non-motor vehicles (non-motorized vehicles) and pedestrians which is next to the straight lane for ground-level motor vehicles;

a left-turn lane for ground-level motor vehicles, which is diverged to left at the ground level and merging to a section of straight lane for elevated motor vehicles travelling from south to north;

a right-turn lane for elevated motor vehicles, which is diverged to right and continuously extends to form a section of straight lane for elevated motor vehicles travelling from north to south;

(2) arranging from east to west:

a straight lane for elevated motor vehicles, and a straight lane for elevated non-motor vehicles and pedestrians which is next to the straight lane for elevated motor vehicles;

a left-turn lane for elevated motor vehicles, which is diverged to left and continuously extends to form a section of straight lane for elevated motor vehicles travelling from north to south, where the end of the straight lane for elevated motor vehicles extends to the ground level and continues going straight from north to south and underpassing the left-turn lane for elevated motor vehicles travelling from south to north;

a right-turn lane for ground-level motor vehicles, which is diverged to right and continuously extends to form a section of straight lane for ground-level motor vehicles travelling from south to north;

(3) arranging from south to north:

a straight lane for underground motor vehicles, and a straight lane for underground non-motor vehicles and pedestrians which is next to the straight lane for underground motor vehicles;

a right-turn lane for elevated motor vehicles, which is diverged to right and continuously extends to form a section of straight lane for elevated motor vehicles travelling from west to east;

a left-turn lane for elevated motor vehicles, which is diverged to left and continuously extends to form a section of straight lane for elevated motor vehicles travelling from east to west;

a section of straight lane for elevated motor vehicles, which is joined with the left-turn lane for ground-level motor vehicles travelling from west to east.

The traffic-light-free overpass at intersections of this functional invention is advantageous in the following aspects.

1) When the overpass is built strictly abiding with the design standards, the scale of the overpass will be 5 times less than those in the market, which facilitates the rational use of the metropolitan tracks and traffic resources.

2) The traffic-light-free overpass at intersections of this functional invention is built on the established roads rather than the new lands, which saves the capital investment.

3) The traffic-light-free overpass at intersections of this functional invention has a complete function, where this overpass has exclusive lanes in each direction without crossings.
