Abstract

Abstract An urban settlement covering a rectangular area is encircled by a multilane peripheral highway connected with several outwardly radiating feeder roads by means of interchanges at the corners of the rectangle. The interchanges include traffic circles enabling left turns and U-turns. Between these interchanges, ramps lead to parking facilities in either direction alongside the peripheral highway and to subway entrances forming part of a rapid-transit system underneath the settlement. This system includes a set of three parallel tracks, formed into endless loops, with the center track traveled by a continuously running express train and the two lateral tracks utilized by shuttle trains which accelerate from standstill at loading and unloading platforms to the speed of the express train and dock with the latter to facilitate the transfer of departing and arriving passengers.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 194 words
A traffic network comprising a plurality of interchanges between a highway and a plurality of intersecting roadways, said highway peripherally encircling an urban settlement, with offstreet parking facilities at a plurality of locations between said interchanges, and local transport means connecting said parking facilities with the interior of said settlement, said local transport means comprising: at least one rail link with three parallel tracks including a central track and two lateral tracks; a continuously running passenger carrier on said central track; a pair of intermittently moving shuttle carriers on said lateral tracks; and several stations each forming a loading platform alongside one of said lateral tracks and an unloading platform alongside the other of said lateral tracks; said loading platform giving access to one shuttle carrier upon a halting thereof at the station for boarding by waiting passengers, said unloading platform being accessible to arriving passengers on the other shuttle carrier upon a halting of the latter at the station, said shuttle carriers being accelerable to the speed of said continuously running carrier and being provided with docking means for temporarily locking onto said continuously running carrier to facilitate the transfer of passengers therebetween.
Claim 2
Dependent Claim 194 words
A traffic network comprising a plurality of interchanges between a highway and a plurality of intersecting roadways, said highway peripherally encircling an urban settlement, with offstreet parking facilities at a plurality of locations between said interchanges, and local transport means connecting said parking facilities with the interior of said settlement, said local transport means comprising: at least one rail link with three parallel tracks including a central track and two lateral tracks; a continuously running passenger carrier on said central track; a pair of intermittently moving shuttle carriers on said lateral tracks; and several stations each forming a loading platform alongside one of said lateral tracks and an unloading platform alongside the other of said lateral tracks; said loading platform giving access to one shuttle carrier upon a halting thereof at the station for boarding by waiting passengers, said unloading platform being accessible to arriving passengers on the other shuttle carrier upon a halting of the latter at the station, said shuttle carriers being accelerable to the speed of said continuously running carrier and being provided with docking means for temporarily locking onto said continuously running carrier to facilitate the transfer of passengers therebetween.
Claim 3
Dependent Claim 18 words
A traffic network as defined in claim 1 wherein said tracks form a closed path for said carriers.
