Definitions

  • the present invention relates to a flyover bridge for a road intersection.
  • Another conventional solution to the problem posed by the crossing of two traffic routes is to elevate one of the routes allowing the other to pass underneath. It is an improvement over traffic lights because it allows both routes to proceed simultaneously rather than alternately, thereby allowing an increased volume of traffic along each route.
  • the present invention aims at solving the above noted problems.
  • the present invention is intended to provide a new intersection system, in particular a new elevated flyover bridge, which uses less land, is small in scale to thereby permit use in city environment and yet is convenient for automobiles to go straight on or turn right or left, either entirely free of interruption by traffic lights or 5 subject to the least possible interruptions.
  • Another aim of the present invention is to provide an intersection system which is suitable to be built by reforming an existing road intersection.
  • the object of the present invention is a flyover bridge designed to connect two road sections leading to an intersection by passing over the said intersection io and the other road sections which lead to it, characterised in that it is
  • unidirectional in that it is curved in a plan parallel to the plan of the intersection so as to reduce the longitudinal distance between its two ends; and in that the roadbed of the flyover bridge is inclined with respect to a plan parallel to the plan of the intersection towards the radius of the curvature.

  • the third and the fourth road sections 3, 4 run both east-west and include both a plurality of eastbound and westbound traffic lanes (not illustrated in figure 1 and 2), while the fifth road section 5 (figure 2) runs south-east-north-west and also includes a plurality of south-eastbound traffic lanes and north-westbound traffic lanes (not illustrated in figures 1 and 2).
  • a first unidirectional flyover bridge 6 connects a north-eastbound traffic lane 21 a of the second road section to a northbound lane 1 1 a of the first road section passing over the intersection 10 and the third, fourth and fifth road sections 3, 4, 5 thus permitting for a continuous traffic flow from the first to the second road sections 1 , 2 in an essentially north direction.
  • a second unidirectional flyover bridge 7 connects a southbound lane 12a of the first road section 1 to a south-westbound lane 22a of the second road section 2.
  • the said flyover bridges 6, 7 allowing both routes to proceed continuously and simultaneously.
  • a vehicle on the northbound traffic lanes 11 of the first road section 1 wishing to go left or right and join any one of the third, fourth or fifth road sections 3, 4, 5 can do so normally by following a different northbound lane 1 1 b not leading to the flyover bridge 6.
  • the traffic flow from either one of the first or second road sections 1 , 2 to either one of the third, fourth or fifth road sections can be fluidized and handled with less interruptions due to the fact that the traffic flow going straight from the first road section 1 to the second road section 2 has no influence on the rest of the traffic at the intersection 10 due to the flyover bridges 6, 7.
  • Figure 3 illustrates another embodiment of the invention in which four road sections lead to an intersection 20.

  • the more curved the curve 8, 80 of the flyover bridge according to the invention the shorter the longitudinal distance between the two ends 6a, 7a, 60a, 70a of the flyover bridge 6, 7, 60, 70.

  • the roadbed 6b, 7b, 60b, 70b of a flyover bridge 6, 7, 60, 70 according to the invention is further designed so as to be able to clear itself from snow, or small debris which could accumulate on the said roadbed. More precisely and as illustrated in figure 5, the said snow, dust and small debris are pressed down under the pressure of the tires through the cells 81 in a special container 82 placed under the roadbed 6b, 7b, 60b, 70b where they are collected.
  • flyover bridges according to the invention have many advantages: it allows continuous traffic in at least two directions and permits to eliminate traffic lights in those directions.
  • the curvature of the said flyover bridge while not stopping the traffic forces the vehicles to slow down to a safe speed level. Due to the said curvature of the flyover bridge, the longitudinal distance between the two ends of the flyover bridge according to the invention can be greatly reduced, hence offering an efficient solution for congested intersections having small scale ideal to use in an urban area.
  • flyover bridges according to the invention can be fitted at low cost on any existing intersections to connect any one of the road sections leading to the said intersection and with limited aesthetic impact.

Abstract

La présente invention concerne un pont de croisement à niveaux différents (6, 7, 60, 70) conçu pour relier deux sections routières (1, 2, 100, 200) qui mènent à une intersection (10, 20) en passant par-dessus ladite intersection (10, 20) et les autres sections routières (3, 4, 5, 300, 400) qui y mènent. La présente invention est caractérisée en ce qu'elle est unidirectionnelle, en ce qu'elle est incurvée dans un plan parallèle au plan de l'intersection (10, 20) afin de réduire la distance longitudinale entre ses deux extrémités (6a, 7a, 60a, 70a) ; et en ce que la plateforme (6b, 7b, 60b, 70b) du pont de croisement à niveaux différents est inclinée par rapport à un plan parallèle au plan de l'intersection (10, 20) vers le rayon de la courbure.
