CA2645180A1 - Hexagonal roadway system and traffic control system thereof - Google Patents

Abstract

The present invention relates to the urban roadway system and accompanying underground railway system, which provide the efficient use of limited constructible areas of the congested cities, and also relates to the traffic flow control system capable of the effective control of vehicular movements through the roadways. In the whole or partial areas of a city, the roadway network is constructed and connected in the honeycomb-like net structure. Compared with a typical tetragonal city, the hexagonal city of the present invention can reduce 22% of road extent, 63% of road area and 30% of constructible area in total, and the traffic flow can be improved enormously. The present invention also proves that the hexagonal roadway system enables vehicles to move in average 75% less time without meeting stop-signals by the synchronized signal system for traffic flow controls

Claims (8)

1. [1] A method of constructing roadways comprising: constructing inter-block roads formed by means of connecting a roadway network of the whole or partial areas of a city in the net structure of hexagonal meshes like the cross-section of a honeycomb, and constructing inner-block roads Inside each hexagonal block divided by said inter-block roads of said roadway network, and placing buildings or facilities which are suitable for the topographic or geographic properties of said block in the areas divided by said inner-block roads, and connecting the roads beside buildings or facilities to the respective said inner-block roads.
2. [2] The method of constructing roadways of claim 1, wherein a group of said inner-block roads includes orthogonal roads, circular roads and other local roads, and each of said orthogonal roads connects the central part of a said block with those of other adjacent said blocks, and intersects the corresponding inter-block roads, and said circular roads of a said block are arranged in the appropriate intervals one another, and intersect the respective said orthogonal roads of the same block.
3. [3] The method of constructing roadways of either claim 1 or claim 2, wherein the central land of each said block is provided for a central plaza, governmental building, library, or other architectural facilities of public use.
4. [4] The method of constructing roadways of claim 3, wherein underground railways are installed under said orthogonal roads and said inner-block roads with possible entrance of two different lines of said railways on the parallel lines of a platform in a station, and stations for said railways are built under a central plaza or a certain intersection of said orthogonal roads and said inner-block roads.
5. [5] A method of establishing traffic control system comprising: connecting a roadway network of designated urban areas in the net structure of hexagonal meshes like the cross-section of a honeycomb, wherein each inter-block road of said roadway network containing at least 2 lanes per way, and each intersection contains 3 different inter-block roads, and every intersection except in outskirts or borderlands of said roadway network is connected with three adjacent in-tersections through said inter-block roads, and signal lights of each said in-tersection are set up for the corresponding turns of 6 traffic-lines.
6. [6] The method of establishing traffic control system of claim 5, wherein said signal-cycle of every said intersection consists of 3 signal-units of identical interval for allowing left-turns according to the predetermined order for said traffic-lines of the three roads of each said intersection, and the allowable speed for vehicles and the length of said signal-cycle are adjustable to cover 2 sections per signal-cycle.
7. [7] The method of establishing traffic control system of claim 6, wherein setting up said order of left-turns counterclockwise by one and one sequence for the three pairs of said traffic lines, the vehicles of each pair of traffic-lines running on either side of a roadway simultaneously pass overall intersections of unitary roadway network with left-turn during a signal-cycle.
8. [8] The method of establishing traffic control system of claim 7, wherein the go-signals of the two adjacent crosswalks of the other side of said roadway are turned on together with said left-turn, and pedestrians can cross said crosswalk half by half through the mid-safety island.
