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.

       9 . The hexagonal roadway system of the urban areas of a city comprising:
 a plurality of intersections each being connected normally with three adjacent intersections of an identical kind in different directions through the respective sections of the inter-block roads dividing every unit-block and being overground, single-leveled and double-sided;   a plurality of orthogonal roads being formed by connecting the respective central parts of adjacent unit-blocks one another and intersecting the corresponding said inter-block roads;   a plurality of circular roads being arranged in appropriate mutual intervals and intersecting every said orthogonal road inside each said unit-block; and   a traffic control system capable of centralized control over said inter-block roads.   
   
   
       10 . The hexagonal roadway system of  claim 9  including:
 underground railways being installed under said orthogonal roads and being paralleled between a plurality of different lines on the identical level of a platform of a station.   
   
   
       11 . The traffic control system of  claim 9  including:
 the signal-cycle being defined to be the approximate value of double the required time for a vehicle to run one said section at a specific speed and being applied identically at every said intersection;   a signal-unit being defined to be a segment of one third of one said signal-cycle; and   a pair of traffic-lines being defined to be the round course of a vehicle toward a distant destination being completed through alternating between left-turn and right-turn at each said intersection of said inter-block roads.   
   
   
       12 . The traffic control system of  claim 9  including:
 a left-turn signal for a pair of said traffic-lines being generated simultaneously at each said intersection during a said signal-unit.
