Hexagonal roadway system and traffic control system thereof

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.

Description

TECHNICAL FIELD [0001]The present invention relates to the urban roadway system and accompanying underground railway system, which provide the effective 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.BACKGROUND ART [0002]Using tools and machines, human beings customarily made things out of lines and tetragons. And furthermore, for thousands of years they have filled their surrounding spaces with the artifacts shaped in rectangles except in the case for incidental ornaments. Densely populated cities have been so constructed with the roadways inter-connecting the main placed of their districts directly as to have many crossroads. All the traffic problems caused by the expanded supply of automobiles have been regarded as the inevitable products of modern civilization. So far as every intersection of a conventional roadway system in concerned, it ...

AI Technical Summary

Benefits of technology

[0079]Ceaseless widening of roads in conventional tetra-cities comes from the fact supposing the road-capacity for entering cars during congestion of an intersection. The increase of traffic lanes forces drivers to choose one of the lanes. However, drivers are used to choose the middle lanes unintentionally. For such a reason, assigning more middle lanes causes the lack of left or right lanes, which results in another traffic problem. As the signal lights turn on in an intersection, changing lanes occurs between vehicles of other directions, and leads to the vicious circle of accumulative congestion.

[0080]The 3-way intersections of hexa-city not only eliminate all the hazardous elements of tetra-city, but also enhance the traffic efficiency by reducing the length of a signal-cycle approximately to 1 minute from 3 minutes of conventional crossroads. Drivers can choose lanes single-mindedly and, with broader fields of view while crossing intersections, make smoother traces of about 60 degree turning angle, which provides almost constant running speed without slowdown cornering. On the other hand, pedestrians can cross the roads safely during a sufficient time longer than a half of the signal-cycle without vehicular hindrance.

[0081]Symmetrically arranged six-side, six-bent inter-block roads induce vehicles to scatter spontaneously, and congestions can be absorbed within each block by assigning the most crowded facilities of public use to the central area. As vehicles have to stop and park somewhere on the inner-block roads, the disruptions between vehicles are remarkably decreased. Two remote spots on a hexagonal roadway network can be interconnected at the least distance of geometrical equality when compared with any other roadway networks, and vehicles on the roadway can pass the consecutive intersections without meeting any stop signals through the traffic control system of signal synchronization.

[0082]Therefore, hexa-cities eliminate the need of circumventing freeways which cause a new traffic problem of frequent jams around their interchanges or junctions.

[0083]As two different lines of underground railways installed along the orthogonal roads can come parallel on a floor of a station, passengers can transfer at the same platform.

[0084]The fluent curvatures of roadways and railways reduce frictional losses and consuming energies due to the de / acceleration of vehicles. The reduction of travel time and stopping frequency of vehicles enhance the efficiency of traffic, and proportionally, the life span of vehicles and roadways can also be prolonged, and urban pollution can be reduced enormously in result

Problems solved by technology

So far as every intersection of a conventional roadway system in concerned, it has been problematic even for a highly advanced computer system to establish a complete traffic flow control system which should combine 12 traffic-lines plus bi-directional 4 crosswalks.

But no perfect circles and spheres exist because of the effect of external forces.
