Abstract

The invention discloses a rapid passing overpass. The rapid passing overpass comprises a ground surface vehicle traveling layer (1) and a viaduct (2). The rapid passing overpass is characterized in that the ground surface vehicle traveling layer (1) is approximately discoid; all lane lines in the disc are anticlockwise; all lane lines (3) outside the disc are clockwise; inlets of the lane lines in the disc are provided with left turn lane lines and traffic signs for prohibiting direct vehicles to enter; no matter whether the viaduct (2) has a single-layer structure or a double-layer structure, and no matter whether direct lane lines (5) are available, the inlets (6) are all provided with traffic signs for prohibiting left turn vehicles to enter; a culvert (7) which is arranged below the viaduct (2) and is close to the edge of the discoid vehicle traveling layer is internally provided with a U-shaped lane line (8) turning left; the ground surface vehicle traveling layer (1) is internally provided with a left turn lane line (10) which rotates by 90 degrees anticlockwise, is connected with a corresponding inlet and a corresponding outlet, and does not exceed a disc center point (9). According to the rapid passing overpass provided by the invention, the traffic mode of completely insulating a direct traveling vehicle and a left turn vehicle is realized, so that the transport capacity of the overpass doubles that of the overpass with the same width, and therefore, the rapid passing overpass has an applicable social value.

Description

A kind of fast logical overpass bridge

Technical field

The present invention relates to the overpass bridge on road junction, particularly a kind of fast logical overpass bridge.

Background technology

Overpass bridge on current intersection, the particularly rotary island shape overpass bridge only having one deck above ground level, its straightgoing vehicle and left and right changing trains or buses all can go up bridge, lamp commander order is current in accordance with the instructions, bridge just has craspedodrome respectively, and left and right turn of three kinds of tracks, therefore just decrease the quantity of direct lane, again because being provided with left-hand bend indicator lamp therefrom, adding the stand-by period of straightgoing vehicle and causing traffic freely not cause traffic problems.

Summary of the invention

The object of the invention is the weak point overcoming existing overpass bridge, and the fast logical overpass bridge providing a kind of straightgoing vehicle and left turning vehicle to separate completely, this design scheme is also applicable to remake old bridge, makes the smooth traffic of intersection produce social benefit.

A kind of fast logical overpass bridge is made up of drive a vehicle layer (1) and viaduct (2) of ground, it is characterized in that ground driving layer (1) is discoid in being close to, in disk, all lane lines are all counterclockwise, the outer all runways (3) of disk are all toward the clockwise direction, in disk, the entrance of runway is provided with left turn lane, forbid the traffic sign that straightgoing vehicle enters, no matter viaduct (2) is single, double-decker, the traffic sign forbidding left-hand rotation car to enter is equipped with or without straightgoing vehicle diatom (5) its entrance (6), under the bridge of viaduct (2), there is the U-shaped lane line (8) of oriented left-hand bend in a culvert (7) at edge close to discoid driving layer (1).

Be provided with in ground floor runway (1) turn counterclockwise about 90 degree, connect corresponding import and export, be no more than the left turning vehicle diatom (10) of disc centre point (9) also can according to traffic need ground floor runway (1) interior setting to turn counterclockwise about 90 degree, the import and export that connect correspondence, the two car confluces that left turning vehicle diatom (11) is passing in and out disk that exceed disc centre point (9) are provided with tow-away zone.

Accompanying drawing explanation

Fig. 1 is the plane lane line schematic diagram of viaduct.

Fig. 2 is that ground floor connects corresponding import and export, is no more than the left-hand bend of disc centre point and the lane line of U-shaped and right-turn lane line floor map.

Fig. 3 is the lane line floor map of ground floor towards counterclockwise single direction.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in more detail:

Because no left turn car passes through on reference Fig. 1, viaduct (2), all tracks all return straightgoing vehicle to pass through, and because straightgoing vehicle diatom (5) increases, single, double floor height bridge formation (2) no longer include the current traffic lights of left-hand rotation car, can significantly improve bus capacity.

With reference to Fig. 2, because pavement behavior is had nothing in common with each other, so the lane line of being driven a vehicle on ground in layer (1) is designed to connect corresponding turnover, mouth as required, be no more than the left turning vehicle diatom (10) of disc centre point (9), with U-shaped lane line (8), under traffic lights commander, disk is left in the synchronous operation of subtend car, completes left-hand rotation car fast passing, the right-hand rotation runway of right-hand rotation car outside disk runs.

With reference to Fig. 3, when the runway in disk is designed to connect corresponding entering, outlet, exceed the lane line (11) of disc centre point (9), when vehicle enters, all vehicles are substantially all in operation conditions in the same way, owing to having the lane line of more than two in disk at least, therefore mutual spacing enough allows outgoing vehicles lane change run and leaves, and in turnover car confluce, be provided with tow-away zone, no matter pass in and out the left-hand bend vehicle in disk track, at least can hold after this Che Shicai enters this district leave close to road ahead all will be observed during this region, so ensure road unimpeded under not having traffic lights to command.

It is same as the prior art that part is not stated in this enforcement.

Claims

1. one kind soon logical overpass bridge be made up of drive a vehicle layer (1) and viaduct (2) of ground, it is characterized in that ground driving layer (1) is discoid in being close to, in disk, all lane lines are all counterclockwise, the outer all runways (3) of disk are all toward the clockwise direction, in disk, the entrance of runway is provided with left turn lane, forbid the traffic sign that straightgoing vehicle enters, no matter viaduct (2) is single double-decker, and whether straightgoing vehicle diatom (5) its entrance (6) is equipped with the traffic sign forbidding left-hand rotation car to enter.

2. fast logical overpass bridge according to claim 1, under it is characterized in that the bridge of viaduct (2), there is the U-shaped lane line (8) of oriented left-hand bend in a culvert (7) at the edge close to discoid driving layer (1).

3. fast logical overpass bridge according to claim 1, it is characterized in that being provided with in ground floor runway (1) turn counterclockwise about 90 degree, connect the import and export of correspondence, be no more than the left turning vehicle diatom (10) of disc centre point (9).

4. fast logical overpass bridge according to claim 1, it is characterized in that being provided with in ground floor runway (1) turn counterclockwise about 90 degree, connect corresponding import and export, exceed the two car confluces that the left turning vehicle diatom (11) of disc centre point (9) is passing in and out disk and be provided with tow-away zone.
