Benefits of technology

[0007] A primary object of the present invention is to provide a crossroad without disadvantage mentioned above which permit continuous traffic flow.
[0008] Another object of the present invention is to provide a crossroad where vehicles can either drive straight through or turn without interruption.
[0009] Another object of the present invention is to provide a crossroad where vehicles can make turns in several ways.

Problems solved by technology

Traffic jam at intersection of roads is a conventional problem all over the world.
Multi-level roadway interchanges, which permit continuous traffic flow, are commonly used, but they take up much land, time and money to build and are impractical in a crowded city environment.
These types of mono-level interchange cannot effectively handle large volume in major cities.
In addition, traffic accidents occur frequently at crossroads.

Embodiment Construction

[0031] Referring to FIG. 1 and FIG. 2, a crossroad comprises road 1 and road 2 intersected from each other. The road 1 has two roadway 11 and roadway 13 separated by a median 12. The roadway 11 is for traffic traveling in one direction. The roadway 13 is for traffic traveling in one direction opposition to that of the roadway 11. The road 2 has roadway 21 and roadway 23 separated by a median 22. The roadway 21 is for traffic traveling in one direction. The roadway 23 is for traffic traveling in one direction opposition to that of the roadway 21. Two entrances for U-turn 121 and 122 are provided between the roadway 11 and the roadway 13 and on opposite side of the road 2 respectively. Two entrances for U-turn 221 and 223 are provided between the roadway 21 and the roadway 23 and on opposite side of the road 1 respectively. Two entrances for turn 222 and 224 are provided between the roadway 21 and the roadway 23 and on opposite side of the road 1 respectively.

Abstract

The present invention relates to road traffic field, providing a two-level continuous flow crossroad and construction method and prefabricated parts thereof. The crossroad comprises a first road and a second road intersected with each other. At least one overpass or underpass crosses the first road and merges with the second road. The overpass or underpass each has a bypass branched from one side thereof. The bypass merges with the first road. The construction method includes constructing the two roads or starting from two existing roads. The prefabricated parts include a vaulted strip main body for overpass and vaulted strip for U-turn. Upon the crossroad of the present invention, traffics can make left turn, right turn and U-turn and go ahead without interruption. The crossroad of the present invention has simple structure and takes up less land.

Description

CROSS REFERENCES TO RELATED APPLICATIONS [0001] This application is related to and claims priority to Chinese Application No. 200510033805.7, filed Mar. 22, 2005, incorporated herein by reference in its entirely. BACKGROUND OF THE PRESENT INVENTION [0002] 1. Field of Invention [0003] The present invention relates to a crossroad, and more particularly to a two-level continuous flow crossroad and construction method and prefabricated parts thereof. [0004] 2. Description of Related Arts [0005] Traffic jam at intersection of roads is a conventional problem all over the world. Multi-level roadway interchanges, which permit continuous traffic flow, are commonly used, but they take up much land, time and money to build and are impractical in a crowded city environment. Major crossroads controlled by traffic lights are also widely employed, but vehicles are required to stop on the red light, and are free to go on the green light. These types of mono-level interchange cannot effectively hand...
