Description

The present disclosure relates to track-based transportation systems.

As a new means of transportation other than buses and railroads, there is known a track-based transportation system in which running wheels with rubber tires run on tracks. This type of track-based transportation system is generally called a "new transportation system".

In such a track-based transportation system, in order to effectively use the space on the existing roads, the track on which the vehicle travels is formed as an elevated track arranged on an elevated bridge. For example, in US Pat. No. 6,200,000, tracks are formed on a plurality of spaced struts on a median strip. The track is formed by a pair of main girder beams fixed on the struts and a plurality of connecting beams connecting the pair of main girder beams. Moreover, in such an elevated track, stations are arranged on the road as elevated stations.

JP-A-58-188748

Such an elevated track requires the provision of a plurality of elevated bridges and the provision of bridge girders on the elevated bridges, which may result in high construction costs. Therefore, if an elevated track is used for the entire line, the installation cost will increase. In addition, if the track is installed at the same height as the road instead of using an elevated track, it is necessary to install a railroad crossing like a railway so that cars and pedestrians can cross the track. However, in track-based transportation systems, guide rails (guide rails) that guide the vehicles and overhead wires (overhead lines) that supply power to the vehicles crawl on the tracks in order to operate the vehicles (guide rail-type railway vehicles). It extends continuously at a low height such as Therefore, a structure that crosses the track like a railroad crossing will be cut off from the guide rail and the overhead contact line, so it cannot be applied, and an overhead crossing will be required. As a result, the installation cost increases.

The present disclosure has been made to solve the above problems, and aims to provide a track-based transportation system capable of reducing construction costs.

In order to solve the above problems, the track-based transportation system of the present disclosure includes a road having lanes, a guide rail-type track arranged at a position higher than the road and provided between the adjacent roads, a support structure for supporting the track with respect to the road, the track having a station installation section having a station and an embankment section connected to the station installation section, the support structure comprising: In the station installation section, a first elevated portion that supports the track above the road, and in the embankment section, the track is supported above the road at a position lower than the station installation section, and the track and an embankment structure section in which a traffic path is formed so as to intersect and penetrate through the interior.

According to the track-based transportation system of the present disclosure, installation costs can be reduced.

(Effect)
According to the track-based transportation system 1 configured as described above, the track 3 is supported by the first elevated portion 51 in the station installation section 3A, and by the embankment structure portion 53 in the embankment section 3B. Therefore, the station 35 can be installed as an elevated station. Although the station 35 needs to be larger in the width direction Dw than the track 3, the station 35 can be installed without blocking the first road 21 by being an elevated station. That is, there is no need to widen or change the width of the first road 21, and the station 35 can be installed at a reduced cost. Furthermore, in the embankment section 3B, the laying cost can be reduced by supporting the track 3 with the embankment structure 53, which is less expensive than the elevated structure. Moreover, the embankment structure 53 supports the track 3 at a position higher than the first road 21 to form a traffic route P1 under the track 3 . That is, a passage through which pedestrians can pass is provided under the track surface 31 so as to traverse the track 3 when viewed from above in the vertical direction Dv. In the track 3 on which the contact wire 32b and the guide rail 32a are laid, it is difficult to install a railroad crossing across the track surface 31 because the contact wire 32b and the guide rail 32a cannot be interrupted in the middle. In addition, when a pedestrian bridge is installed over the track 3, it is necessary to install a large-scale pedestrian bridge that also straddles the lane 2a, which increases installation and maintenance costs. On the other hand, by forming the traffic path P1 so as to penetrate the interior of the embankment structure 53, it is possible to form a passage that can traverse the track 3 at a reduced cost. As a result, the cost of laying the entire track 3 can be reduced. As a result, when laying a new track 3 on land where the first road 21 and the second road 22 have already been laid, as in a developing country, the track 3 can be laid at low cost. .

Furthermore, since a plurality of first main leg portions 51a are arranged apart from each other in the running direction Dr, and a space is formed under the first main girder portion 51b of the station 35, it can be effectively used as an installation place related to station facilities.

In addition, the track 3 is supported on the intersection 25 by the second elevated portion 52 in the bridge section 3C. Therefore, at the intersection 25, the automobile can run under the track 3 so as to cross the track 3 when viewed from above in the vertical direction Dv. Therefore, at the intersection 25, the vehicle can pass without affecting the track 3 on which the contact line 32b and the guide rail 32a are laid.

In addition, in the embankment structure portion 53, the bottom of the track 3 is filled with the frame portion 53a and the filler 53b, and no space is formed. However, by incorporating the box culvert 53c, the traffic path P1 can be easily formed.

Moreover, the difference in height between the station installation section 3A and the embankment section 3B is set to within 4.3 m. Therefore, the height difference between the station installation section 3A and the embankment section 3B becomes small, and it is possible to suppress deterioration of the ride comfort of the vehicle 4 traveling on the track 3.例文帳に追加Moreover, since the height difference between the station installed section 3A and the embankment section 3B is small, the installation cost of the first elevated portion 51 and the embankment structure portion 53 can be suppressed.

(Other embodiments)
As described above, the embodiments of the present disclosure have been described in detail with reference to the drawings, but the specific configuration is not limited to these embodiments, and design changes etc. within the scope of the present disclosure are also included. .

In addition, in this embodiment, the traffic path P1 is formed in a box culvert, but it is not limited to such a structure. The traffic route P1 may be formed through the embankment structure 53 so as to be able to pass under the track surface 31 . Therefore, the traffic path P1 may be provided by forming a hole penetrating the embankment structure 53 so as to form a tunnel. Also, a plurality of traffic routes P1 may be formed.

Further, in the inclined section 3D, the track 3 may be supported only by the first elevated portion 51 or the second elevated portion 52, or may be supported only by the embankment structure portion 53.
