Description

The utility model relates to road construction and can be used in the construction of intersections at different levels of roads.

There are various types of cloverleaf road interchanges that contain roads intersecting at different levels, adjacent to intersecting roads, four separate right-hand driveways and four left-hand ring exits.

For example, a traffic intersection is known [RU 2135673], including the intersection of roads located at different levels, forming four sectors in plan, the main overpass located in the center of the intersection on one of the roads, and in each sector there is a separate right-turn adjacent to intersecting roads driveway and left turn ring exit.

In “clover leaf” traffic interchanges, including the traffic interchange under consideration, right turns are made by driving along separate passages, and left-turning traffic is made after driving through the center of motorways intersection by turning to the right onto the roundabout with embedding to the center of motorways intersection in the direct flow directions.

The advantage of a clover leaf type of traffic intersection, including the transport interchange under consideration, is the provision of continuous traffic in two directions along intersecting roads.

However, in a “clover leaf” type of traffic intersection, including the transport interchange under consideration, it is difficult to maneuver the mutual rearrangement of transport in sections of the road located between the adjoining area of the left-hand turn exit for one left-hand direction and the area for unlocking from the left-hand drive exit for the left of another left-turning direction (on inter-ring sections), in which cars flowing into the direct flow from a left turn in front of the center eresecheniya roads should be reconstructed with cars, which run on a left turn, to exercise the right turn after crossing the road center.

In addition, in a “clover leaf” type of traffic intersection, including in the transport interchange under consideration, the mileage for transport when turning in the opposite direction is large, since for this a car must travel a path along two left-hand roundabouts (along two “clover lobes” "), as well as for vehicles making a right-hand turn from an area located near the center of the intersection of highways, because for this a car must travel a path along three left-hand roundabouts (three" clover m petals "), the radius of which in the transport interchanges of the type in question is significant, which is associated with ensuring the safety of the rearrangement of transport on inter-ring sections, as well as with the possibility of increasing the speed mode with an increase in the specified radius. The increase in mileage when performing these maneuvers causes the greatest inconvenience for public transport routes, carried out, in particular, in urban conditions.

Known transport interchange described in [textbook "Research and design of urban roads", M .: Transport, 1981, p.207, 209], which refers to the transport interchange type "improved clover leaf", and was selected by the author as the closest analogue.

The indicated interchange, including the intersection of roads located at different levels, as well as the main overpass located in the center of the intersection on one of the roads, forms four sectors in plan, each of which has a separate right-turn passage and a left-turn ring exit, adjacent to intersecting roads, departing from one road in the forward direction of traffic after the center of the intersection of roads and adjacent to another road in the forward direction of traffic orth to the center of the intersection of highways. In addition, in each sector, there is a loopback passage, departing from the highway, from which the left-turning ring exit located in this sector leaves, in the section located to the zone of joining of the specified left-turning ring exit, and adjacent to this highway in the section located after specified unlocking zone. At the same time, the left-turning ring exit and the separate loop passage in each sector intersect at different levels, and an additional overpass is located in the zone of their intersection.

In the transport interchange under consideration, the maneuver of mutual rearrangement of left-hand flows on the inter-ring section of the road was eliminated, since the left-hand flow of one direction, entering the road to the center of the intersection of roads, after the specified center of intersection moves along the loopway, which departs from the road to the unlocking zone from the left for left-hand flow of a different direction.

Thus, in the considered traffic intersection for the left-hand flow of each direction, its own separate passage is provided.

However, in the transport interchange under consideration, a significant mileage is required for vehicles making a reverse turn, as well as for vehicles making a right turn from an area located near the center of the intersection of highways, since for this a car must pass along two and three left-turning ring exits ("clover petals "), the radius of which in the considered traffic intersection of the type" improved clover leaf "also has a significant value to ensure the safety of MAKING traffic flows on the inter-ring areas and increase speed limit left turn movement.

The objective of the claimed utility model is to reduce the mileage for vehicles performing a maneuver of a reverse turn and a maneuver of a right turn from a zone located near the center of the intersection of roads.

The essence of the utility model is that in the traffic intersection, which includes the intersection of roads located at different levels, the main overpass located in the center of the intersection on one of the roads, and forms in plan four sectors, in each of which are located adjacent to intersecting roads separate right-turn passage, left-turn ring exit, departing from one road in the forward direction of traffic after the center of intersection of roads and adjacent to another road in the forward direction of transport to the center of the intersection of roads, as well as a loopway departing from the road, from which the left-turning ring exit located in this sector departs, to the unlocking zone of the indicated left-turning ring exit, and adjacent to this highway after the specified unlocking zone , while the left-turning ring exit and loopback passage in each sector intersect at different levels, and an additional overpass is located in the zone of their intersection, according to In each sector model, an arcuate branch branching to the right from the loop passage is located, the branch node of which is located in the zone located inside the left-right rotary ring exit, the radius of curvature of which is less than the radius of curvature of the left-rotary ring exit, adjacent to the same road as the left-rotary ring exit and forming with an additional circular exit located inside the left-turning ring with the part of the loopback passage located in the direction of transport to the branch node Vågå Congress.

In the particular case of the utility model, each of the roads has at least one additional lane of the carriageway on the inter-ring sections of the forward and reverse traffic directions.

The presence in the claimed transport interchange of the main and additional overpasses ensure the continuity of traffic on intersecting highways in the forward and reverse directions.

The presence in the claimed transport interchange located in each sector of the above manner of separate right-hand driveways provides the ability to make right turns from areas located in the forward direction of traffic below the inter-ring sections of roads.

The presence in the claimed transport interchange located in each sector in the aforementioned manner and located at different levels of left-hand ring exits and loop passages provide the possibility of making a separate passage for left-hand flow of each direction, including movement along a left-turn ring exit located in the corresponding sector, movement along the inter-ring section roads and traffic on a loopway located in the forward direction of traffic in adjacent the sector in question.

Thus, the maneuver of mutual reconfiguration of left-hand flows on the inter-ring section of the road was eliminated in the claimed traffic intersection, since the left-hand flow of one direction, entering the road to the center of the intersection of roads, after passing through the center of intersection of the roads, moves along a loopway that departs from the road to the wash zone left-turn ring exit for left-turn flow of a different direction.

Of fundamental importance in the claimed transport interchange is the presence of arched branches located in each sector in the aforementioned manner, forming, in combination with the above parts of the loopways, additional ring ramps having a radius of curvature less than the radius of curvature of left-turning ring ramps. Due to the presence of the indicated additional ring exits, the entrance to which coincides with the entrance to the loopback driveways, in the claimed transport interchange, it is possible to drive cars entering the highway after left-turning traffic on the left-turning ring exit.

The presence of additional ring exits allows you to reduce the mileage for cars making a reverse turn or a right turn from a zone located near the center of the intersection of highways, since when performing the indicated maneuvers after driving through a single left-hand round exit (one "clover lobe") having a relatively large radius , their further movement is carried out respectively on one or two additional ring exits of a smaller radius.

Thus, the technical result achieved in the implementation of the claimed utility model is to reduce the mileage for vehicles performing the maneuver of the reverse turn and the maneuver of the right turn from the zone located near the center of the intersection of roads.

The presence in the particular case of the utility model on each of the roads on the inter-ring sections of the forward and reverse directions of traffic, at least one additional lane of the carriageway provides a separate passage on the specified section of vehicles entering the highway, which improves the conditions for the rebuilding of traffic flows on the inter-ring sections , increases the throughput of these sections, and also helps to eliminate interference and increase the speed of movement in the forward direction.

The figure shows a General view of the claimed transport interchange.

The traffic intersection includes the intersection at different levels of roads 1 and 2. In the zone of intersection of roads 1 and 2 on the overlying road, in particular, on highway 2, the main overpass 3 is located.

The traffic intersection forms in the plan four sectors 4, 5, 6 and 7.

In each sector 4, 5, 6 and 7 there is a separate right-turn passage 8 adjacent to the roads 1 and 2, in particular having an arched shape, a left-turn circular exit 9 and a loop passage 10. Each left-hand circular exit 9 has an unlock zone 11 from one of roads 1 or 2, respectively, which is in the forward direction of the vehicle after the center of intersection of roads 1 and 2 (not indicated in the drawing), and an adjoining zone 12 to another road, which is in the forward direction of the vehicle to the center of sections of motorways 1 and 2. Each loopway 10 departs from the corresponding motorway 1 or 2 in section 13, which is located in the forward direction of traffic to the zone 11 for joining the left-hand ring exit 9 from this highway, and adjoins this highway in section 14, located in in the forward direction of traffic after zone 11. At the same time, the left-turning circular exit 9 and the loopway 10 located in the same sector intersect at different levels, and in the zone of their intersection there is an additional uteprovod 15. In particular, the levorotatory circularly exit 9 situated in said intersection zone at a higher level, and thereon is placed a further overpass 15 ..

In addition, in each sector 4, 5, 6 and 7, an arcuate branch 16 is located branching from the loop passage 10 to the right in the forward direction of the vehicle, the branch assembly 17 of which is located in the zone inside the left-hand ring exit 9, which has a radius of curvature less than the radius of curvature of the left-turning ring exit 9. The arcuate branch 16 is adjacent to the same road, respectively 1 or 2, which is adjacent to the left-turning ring exit 9. In particular, the arc-shaped branch 16 has a left-turning ring m exit 9, the common zone 12 adjacent to the corresponding road 1 or 2. The arcuate branch 16 in conjunction with the part of the loop passage 10, located in the direction of transport to the node 17 branches, form an additional ring exit located inside the left-hand ring exit 9.

Each of roads 1 and 2 has at least one additional lane 18 of the carriageway (two additional lanes 18 are indicated on the drawing), in particular, located in such a way that one of its end sections is connected with sections adjacent to the corresponding highway 1 or 2 of the left-hand circular exit 9 and the arched branch 16 (in particular, with a common zone 12 adjacent to the corresponding highway 1 or 2), and its other end section is connected with tkom 13 of the same road, which leaves the loop passage 10 from it.

The movement of traffic flows at the traffic intersection is as follows.

Right turns from the zone located in the forward direction of the vehicle below the center of intersection of roads 1 and 2 are carried out along separate passages 8.

Left-hand traffic for traffic flows moving in the forward direction, respectively, on roads 1 or 2, is carried out by turning to the right after passing the center of intersection of these roads on the corresponding left-turning ring exit 9 with subsequent passage on an additional lane 18 of the carriageway of the road, respectively 2 or 1, and then on loop passage 10 with embedding in a direct flow stream.

So, for example, to make a left turn, the flow moving in the forward direction along the road 1, passing the center of intersection of roads 1 and 2, turns right in zone 11, where the left-hand ring exit 9 located in sector 4 is unlocked, moves along the indicated left-hand turn roundabout 9, intersecting at different levels with the loopway 10 located in sector 4. Next, the specified stream enters highway 2 in zone 12, located to the center of intersection of roads 1 and 2, and moves along additional lanes е 18, located on the inter-ring section of the road 2. After passing the center of intersection of roads 1 and 2, the specified stream on section 13 of the road 2 enters loopback 10, located in sector 7, adjacent in the forward direction of traffic with sector 4, and moves along the specified loop passage 10, intersecting at different levels with the left-hand ring exit 9 located in sector 4. Next, the stream in question enters highway 2 in section 14, integrating into the direct flow stream moving along highway 2.

To perform a reverse turn, a traffic flow moving in the forward direction, respectively, on roads 1 or 2, performs the left-turn movement described above in the first and second sectors in the direction of travel until the branch 17 is reached in the second sector, and then moves along the arcuate branch 16, after which it enters, respectively, on highway 1 or 2, driving along the additional lane 18 of the carriageway located on its inter-ring section and along the looped passage located in the third sector in the direction of travel 10 s leduyuschim insertion into the flow of the forward direction, which is the inverse of the initial direction of traffic.

So, for example, to perform a reverse turn, the flow moving in the forward direction on the road 1 first travels as described above as a left-hand flow, and then after reaching the branch node 17 it moves along the arcuate branch 16 located in sector 7 and enters the road 12 in zone 12 1, passes along an additional lane 18 of the carriageway adjacent to the road 1 and, after the center of intersection of roads 1 and 2, passes along the loopback passage 10 located in sector 6, intersecting at different levels with sector 6 levorotatory annular Congress 9, followed by insertion portion 14 to direct in the direction of flow, moving along the highway 1.

To perform a right turn from a zone located near the center of intersection of highways 1 and 2, the stream moves in the same way as the stream making a reverse turn, and then after reaching the branch node 17 in the third sector, the stream moves along the arcuate branch located in the indicated sector 16, after which the flow moves along the corresponding additional lane 18 of the carriageway and along the looped passage 10 located in the fourth sector along the way, with subsequent integration in the indicated sector line 14, respectively, of road 2 or 1 into a forward flow moving along it.
