Description

PEDESTRIAN SUBWAY
TECHNICAL FIELD
The present subject matter relates to a subway and, more particularly, to an improved and efficient design of a subway designed for pedestrians and/or cyclists.
BACKGROUND
Underpasses are constructed when it is necessary for pedestrians to cross a railway line or a dual carriageway such as an interstate highway. A subway appear at the exits from underground rapid transit systems. The subways when constructed to enable people to cross an ordinary city street are referred to as "pedestrian subway". It is a well acknowledged fact that building a passage underneath road is many times more resource intensive and expensive than constructing a passage above the road. For instance, the estimated cost for an elevated metro rail is around Rs 200 crore per km, while for an underground line, the cost is estimated as anywhere between Rs 500 crore and Rs 600 crore per km and thus, setting a huge cost difference between the two design alternatives.
Due to high cost of constructing a passageway below the earth surface, such a construction has only been reserved and employed for heavily funded projects. Thus, benefits of such a construction have not been realized and utilized to its full extent.
Further, the limitation in constructing and optimally utilizing the subways as aforementioned act as a major hurdle in enforcing pedestrian safety, particularly, in a developing country like India. The pedestrians are most prone to road and train accidents, and statistics show that an estimated 4,280 pedestrians died in road crashes in 2010 and 69,000 pedestrians were injured in 201 1 in road related incidents.
In terms of the cost involved, a foot-over bridge is considered to be the most suitable alternative to building an underground tunnel. However, an overpass or an over bridge is required to use elevators or long ramps in order to make them favorable for wheelchair users and/or mobility handicaps. The said requirement of elevators or ramps to a considerable height above the ground adds up to enormous amounts in constructing the foot-over bridge. Also, there is a general tendency amongst the users to avoid the effort required in climbing up the bridge and hence, it's use.
Therefore in view of foregoing, there is an exigency of a cost effective and easy-to-build underpass passageway that is commercially viable; provides an easy access to pedestrians, cyclists and handicaps etc.; and also helps overcome the aforementioned deficiencies associated with state-of-the-art designs.
SUMMARY
It is a primary object of the present subject matter to construct a subway designed for pedestrians and/or cyclists and other users.
It is another object of the present subject matter to provide a cost-effective and easy-to-build pedestrian subway.
It is yet another object of the present subject matter to provide an underpass passage that is convenient to use and easily accessible to wheelchair users and/or mobility handicaps. The present subject matter described herein relates to a pedestrian subway designed for enabling pedestrians to cross from one side of a road or multi-road intersection carrying vehicular traffic to another side of the road or multi-road intersection, without interrupting the vehicular traffic flow. The pedestrian subway is provided with a tunnel beneath the road or multi-road intersection, the tunnel having a first opening on one side and a second opening on another side of the road or multi-road intersection. The roof of the tunnel at each tunnel opening is maintained at a level higher than the level of the side-of-the-road; and a portion of the tunnel is maintained under the ground by providing slope on side-of-the-road.
In one embodiment of the present subject matter, the side-of-the-road is a footpath.
In another embodiment of the present subject matter, the portion of the tunnel under the ground is a passageway for the pedestrians.
In one embodiment of the present subject matter, there is described a method for enabling pedestrians to cross from one side of a road or multi-road intersection carrying vehicular traffic to another side of the road or multi-road intersection, without interrupting the vehicular traffic flow. A tunnel is constructed beneath the road or multi-road intersection; and the tunnel is provided with a first opening on one side and a second opening on another side of the road or multi-road intersection. The roof of the tunnel at each opening is maintained at a level higher than the level of the side-of-the-road; and a portion of the tunnel is maintained under the ground by providing slope on side-of-the-road.
In another embodiment of the present subject matter, the side-of-the-road is a footpath.
In another embodiment of the present subject matter, the portion of the tunnel under the ground is a passageway for the pedestrians.
These and other advantages and features of the present subject matter will also become readily apparent to those skilled in the art from the following detailed description of the embodiments, having reference to the attached figures, the disclosure not being limited to any particular embodiments disclosed.

DETAILED DESCRD7TION
The following presents a detailed description of various embodiments of the present subject matter with reference to the accompanying drawings. The embodiments of the present subject matter are described in detail with reference to the accompanying drawings. However, the present subject matter is not limited to these embodiments, which are only provided to explain more clearly the present subject matter to the ordinarily skilled in the art of the present disclosure. In the accompanying drawings, like reference numerals are used to indicate like components.
Referring Figs. 1 to 4, the pedestrian subway designed in accordance with an aspect of the present subject matter is well illustrated. Fig. 1 represents a two-lane road (1) carrying vehicular traffic and divided by a divider (2); however, the design as proposed in the present subject matter is applicable and feasible with multi-lane roads as well. The sides of the road (1) have a raised path i.e., a pavement or a footpath (3) as known in state-of-the-art.
The present subject matter proposes to construct a tunnel (4) beneath the ground as represented in Figs. 1 to 4. The tunnel (4) is build by providing a slope on the footpath (3) i.e., a slanted footpath on both sides of the road (1) as also represented in Fig. 2, thereby making a passageway for the pedestrians, including cyclists and/or mobility handicaps to walk through. The slant angle of the footpath (3) is not set to any particular value, and is subjected to change and can be altered as per the requirements of the design. The slant as provided in the footpath (3) also helps in avoiding water logging.
The tunnel (4) opens on both sides of the road (1), with one opening on one side of the road (1) formed by the slanted footpath (3), as also shown in Fig. 4, and a similar opening on another side of the road (1).
According to an aspect of the present subject matter, the road (1) is partially elevated to a predetermined height and upto a predetermined distance, as can be seen in Fig. 3. The road (1) is further excavated partially to a predetermined depth. The dimensions of the elevation and depth provided to the road (1) can be maintained and catered as per the needs and requirements of the design.
It is also in accordance to an aspect of the present subject matter that the slant as provided in the footpath (3), and the partial elevation and depth in the road (1) are not necessarily equal, and are adjusted as per the requirements of the design. According to an aspect of the present subject matter as shown in Fig. 2, the roof of the tunnel (4) is designed at a level higher than the level of the side-of-the-road i.e., a footpath (3) at each tunnel opening.
Although the invention has been described with reference to specific embodiments and ranges used in specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications in the embodiments as disclosed, as well as alternate embodiments of the invention, will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore, contemplated that such modifications can be made without departing from the spirit or scope of the present invention as defined.
