Definitions

  • Collective traffic can also be separated from remaining traffic by constructing elevated drive lanes and tracks for one or more typres of transit vehicles above the streets. This method enables the collective traffic capacity to be increa ⁇ sed without the expense entailed by the construction of underground tunnelways and without needing to utilize valu- able existing road space.
  • Such elevated traffic lanes inten ⁇ ded solely for collective traffic require but small space at ground level, are highly flexible with regard to span,- can be readily constructed quickly- and cheaply, and have- a high traffic capacity.
  • Various types of elevated track-bound traffic systems are known to the art.
  • SE-A-368.730 corresponding to US-A-3,376,830 (Bingham) ; SE-A-226.668 and SE-A-313.328 (both Pneuwais Development); US-A-3,209,702 (Lemoke) ; FR-A-2 203 336 (C.I.M.T.-Lorraine) ; DE-A- 2.309.088 (Baldelli) and DE-B-2.427.771 (Rheinstahl) .
  • this transit system has the same dis- advantages as all other track-bound traffic systems, these disadvantages primarily including a high degree of inflexi ⁇ bility and the inability to adapt to differing traffic requirements.
  • CH-B-402.921 (Bucher) describes the arrangement of vehicle so-called fender means in conjunction with crash barriers, comprising a stepped fender edge, with a progressi ⁇ vely increasing incline on the ender means and vehicle return means which engage the vehicle -wheels.
  • This fender - means has the orm of a. separate element placed on a road surface beneath a post-carried crash barrier. This des ⁇ cation, however, does not provide a solution to the parti ⁇ cular. roblems encountered with elevated lanes for bus traffic.
  • the present invention relates to a pillar-supported elevated lane structure for bus traffic, comprising sequen ⁇ tial arrays of two mutually parallel and mutually opposite lightweight prefabricated structural sections, preferably
  • an elevated lane system for bus traffic of this kind is that it can be used in heavily trafficated parts of a large city while at the same time enabling the superior flexibility of the bus in comparison with other types of public transport vehicles to be utilized to the full in those areas where traffic is not so dense and where the bus is able to leave the elevated highway and join the conventional road and street network of the city or town, optionally along separate lanes reserved solely for bus traffic.
  • the bus driver tends to ensure that the bus follows an ideal driving- line, including permitted "wavering" deviations therefrom, because of the discomfort experienced by both the driver and the passengers when driving up onto the fender edge.
  • the bus is forcibly returned to the ideal driving line when devia ⁇ tions therefrom are excessive.
  • This elevated traffic lane construction also takes into account the problem relating to the so-called sweep- radius which determines the increase in lane width for respective inner and outer wheel tracks.
  • sweep- radius determines the increase in lane width for respective inner and outer wheel tracks.
  • the curve radius drops to the permitted minimum of about 30 m, however, the sweep area and therewith the need for a wider lane increases drastically. In such cases it may be necessary to increase the lane width by some tens of percent of the standard lane width.
  • the aforesaid increase in lane width ensures - despite a considerable increase in sweep area, particularly in curves of " small radius - free and unimpeded driving of the bus without risk of damage to the bus from the lateral barriers.
  • One object of the present invention is to provide an improved elevated lane construction for bus traffic of the aforesaid kind which avoids the aforementioned disadvantages inherent with known elevated traffic lane systems and other disadvantages encountered therewith; which can be constructed readily at low cost; which enables buses of conventional design to be used; and which increases passenger safety.
  • Another object of the invention is to provide an eleva ⁇ ted traffic lane construction in which in the event of an emergency, e.g. in the event of fire while holding the driving line, the bus can be quickly evacuated.
  • An elevated lane system for bus traffic constructed in accordance with the invention is mainly characterized in that the fender means is an integral reinforcing and stiffe ⁇ ning part of a respective structural section, so that both the stepped edge and the progressively inclined profile surface form structural-section defining surfaces.
  • the invention enables the structural sections as a whole to be manufactured more readily and to more slender dimen ⁇ sions, this slender design of the sections meaning that they can be transported more easily to the construction site and facilitating their erection on the tall concrete pillars.
  • the improved strength properties of the sections increase the passenger safety factor, which is of essential importance in the case of elevated traffic lanes, where the risk of failure due to driving against the lateral barriers is naturally much greater than when driving along conventio ⁇ nal roads and highways.
  • the distance from the lateral barriers, at least at one of two opposing structural sections, to the adjacent side of the bus is preferably such as to provide access to the space between the barriers and the bus in the event of an emergency.
  • An elevated lane system for bus traffic constructed in accordance with the invention is primarily intended for manually driven buses.
  • One particular advantage afforded by the inventive elevated lane construction is that it can be readily adapted for automatic vehicle control purposes.
  • the space between mutually opposing structural sections can be utilized to accommodate electric cables or like conductors which permit automatic, contact- less control of a bus with the aid of electronic devices.
  • the lateral barriers may also incorporate guide means of the aforesaid kind or, e.g., guide rails for mechanical guidance.
  • guide means of the aforesaid kind or, e.g., guide rails for mechanical guidance.
  • the lateral barriers act as a noise barrier, the fender means per se serving as a noise screen.
  • the fender means may also incorporate separate sound absor ⁇ bing devices.
  • Figure 1 is a perspective view of a pillar-supported elevated bus-lane construction in accordance with the invention.
  • Figure 2 is a cross-sectional view of the elevated bus- lane construction shown in Figure 1.
  • Figure 3 is a cross-sectional view of a modified bus- lane of asymmetric configuration.
  • Figure 4 finally, is a plan view of a curve of short curve-radius incorporated in the elevated bus-lane construc ⁇ tion of Figure 1.
  • An elevated lane 1 for bus traffic is carried on pillars 2 and comprises a sequential array of pairs of mutually parallel and mutually opposing prefabricated, lightweight structural sections 3 having a length of 24 , for example.
  • the sections 3 of each pair of sections are mounted on respective pillar supports with an intermediate free space of, for example, about 0.9 m, this free space being bridged by respective spaces 4 and 5 which join together respec ⁇ tive opposing sections of each pair.
  • the free space between opposing sections can be filled with a grid as shown at 7.
  • the bus is able to deviate from an ideal driving line, i.e. a "wavering tolerance", to a corresponding extent on either side of said line before contacting or driving onto the stepped portion of the lane construction, which latter affords an unpleasant experience to both driver and passengers.
  • the structural sections 3 exhibit outwardly of the stepped edge 3a an inclined surface of progressively increasing slope.
  • This part of the section profile line serves as a fender means operative to tilt the bus and return it to the driving lane should the bus deviate excessively from the aforesaid ideal driving line.
  • This contour line 3b merges with a respective lateral barrier 3c, the main purpose of which is to prevent the. bus from leaving the elevated lane construction.
  • the fender means forms an integral reinforcing and stiffening part of respective structural sections 3, so that both the stepped fender edge 3a and the profile sur- face 3b exhibiting a progressively increasing slope form defining surfaces of respective structural sections.
  • the aforesaid lateral barriers 3c are provided with additional fender means 6 in the form of two semi-cylindrical elements, which may comprise rubber or a similar material.
  • the lateral barriers 3 are located at a substantial distance from the actual bus lane in a manner to leave a space between the sides of the bus and the respective lateral barriers, this space enabling the bus to be evacuated in an emergency, even with the bus located ut on the line. Because of the symmetrical configuration of the embodiment illustrated in Fig. 2, one such space is found on both sides of the bus. thus permitting traffic to move in two directions on the elevated lane system.
  • Fig. 3 illustrates in cross-section a modified embodi ⁇ ment in which the structural sections 3 are of asymmetric construction.
  • a free space 11 is found only on one side of the bus, outwardly of the bus door 10b illustrated in chain lines in Fig. 3 and shown in its open position.
  • This lane system is thus intended for one-way traffic only.
  • the Fig. 3 embodiment also incorporates additional fender means 6 in the form of elongated cylindrical elements adapted to contact the outer bus wheels 10a should the bus move further towards the lateral barrier 3c upon contact with the stepped edge 3a.
  • the resilient fender means 6 are intended to return the bus to the correct drive lane.
  • Fig. 4 illustrates in plan view a comparatively sharp curve of small radius.
  • the figure illustrates the need of widening the lane located in such a curve, as a result of the increased sweep area of the bus.
  • a curve of the illustrated kind needs to be widened by 0.3 m so as not to appreciably change the driving conditions.
  • the space 4 located between mutually opposing structu- ral sections 3 may accommodate an electric cable, a guide rail, contact rail or like device (not shown) to enable the bus to be controlled automatically with the aid, for example, of electronic and/or mechanical devices.
  • guide and control means may be incorporated in the lateral barrier 3c and/or the fender means 6 carried thereby.
  • the lateral barriers- 3c may incorporate or form sound- screening means so as to act as sound barriers.
  • the lateral barriers may be constructed in different ways and provided with suitable sound absorption devices for achieving the aforesaid sound-damping effect.
  • the structural sections of an elevated traffic-lane construction according to the invention are simple to manufacture and hence it is possible in many cases, without incurring high investment costs, to establish a separate factory or plant at or in the vicinity of an area upon which such an elevated lane construction is to be erected.
  • the structural sections are mechanically strong and highly reliable despite their lightness in weight and slender design, which in turn facilitates their transportation to the construction site and the mounting of the sections on respective concrete pillars.
  • the high mechanical-strength properties also afford additional safety in respect of the passengers, so that traffic using an elevated lane system according to the invention is able to travel with the minimum of risk.

Abstract

Structure (1) de voie surélevée pour le trafic des bus, soutenue par des piliers (2) et comprenant une série séquentielle de paires de sections structurales (3) préfabriquées en matériau léger, opposées et parallèles entre elles, et d'une longueur de 24 m par exemple. Les sections structurales opposées présentent un espace entre elles qui peut être recouvert par un grillage (7). Les sections structurales respectives comprennent plusieurs éléments amortisseurs et correcteurs de direction (3a, 3b; 6). Les éléments amortisseurs constituent une partie de renforcement intégrante d'une section structurale respective (3) et présentent un bord amortisseur en forme de marche (3a) et une surface inclinée (3b) en pente augmentant progressivement qui ensemble forment les surfaces définissant la section structurale en question. Dans les virages la distance entre des sections structurales opposées (3) ou leurs barrières latérales (3c) augmente de manière inversement proportionnelle au rayon du virage. La distance entre les barrières latérales (6) et les côtés du bus est suffisante pour permettre aux passagers d'être évacués du bus en cas d'urgence.
