RANIP Located on the junction of 132’ Ring Road and the Radhaswami Road, Ranip junction is a very important junction as the proposed metro is going to be integrated with the existing GSRTC bus terminal and BRTS. The site houses an interesting demography with residents belonging to many different religions and castes, creating a harmonious environment. Majority of the residents work in the city, so the public transport plays a very important role in their lives.

M

The proposed Ahmedabad metro has two routes: one from the north to the south and from running in the east west direction. The proposed site is Ranip, which lies in the North-South route, one station prior to the Sabarmati station.

METRO STATION AND AN INTERCHANGE

Located adjacent to the existing bus terminus, the proposed metro station at Ranip will serve as an important multimodal transport interface. It thereby becomes essential that the interchange is not merely an infrastructural intervention, but a vibrant, humancentered place of activity. This project seeks to use ‘Transit Oriented Development’ and architecture as a tool to achieve the same. The underground crossing acts as the fulcrum, converging the polarities of the site. Serving as a marketplace and the main access to the metro, the underground creates a parellel path for movement, away from the chaos of the road above. A pavillion proposed on the southern side of the interchange, is a place with shade, a place for commuters to eat, interact and move.

As a case study, the Delhi metro provided important insights into the design and functioning of a metro rail system. The site visit helped classify the experience of transit from point A to B into reference points and segments of the journey.

Transit Oriented Development is the exciting fast growing trend in creating vibrant, livable, sustainable communities. Also known as TOD, it’s the creation of compact, walkable, pedestrian-oriented, mixed-use communities centered around high quality train systems. This helps bring the communities closer to the public transport network, creating a vibrant neighbourhood. Dealing with the last mile to first mile connectivity becomes pivotal to the strategy, so that the user’s interaction with the transit is smooth and hassle free throughout their journey.

CON CER N AND DESIGN APPR OAC H

Given the presence of the GSTRC mall as a heavy mass on the site, the effort in creating a metro station must go into balancing this with a permeable, light structure, unlike most transport structures which are solid and opaque, acting as a dead mass in the midst of a bustling road environment.

The interchange is spilt into different levels, creating more porosity, more visual connection, less chaos on the road, leading to a sustainable design. Such public infrastructure must open out more to the public, rather than catering only to its users.

Of the options for the layout for massing, Layout 2 is most appropriate as it caters satisfactorily, to every node on the junction. The seamless layout comes from the existing axes of movement and transit, without disturbing the existing transit mechanisms.

The double peir ystem helps in creating the space under the bridge, which generates opportunities for public functions like the bus interchange. This helps in making use of the underbridge space whichis generally wasted. It helps in making the structure visually porous and barrier free shaded space for pedestrians and commuters to move around freely. This is complimented by pavillions and shaded places for public gathering at opposite ends which would contribute to dissolving the stark boundaries of new structures by super imposition of human activity along them.

Since the intervention deals with various transit systems, the movement across the interchange becomes all the more important. The interchange functions on three different levels, the underground, the road and the upper metro level. The road level is the platform for the BRTS and GSRTC bus services and also acts as a concourse for the upper metro level. The access to the bus services happens through a raised road level crossing. The underground level acts as a crossing for the road level, and primarity serves as the access to the upper metro platform level. This can be accessed from the four nodal points in the corners of the junction. The level caters to the differently abled user groups through lifts and escalators connecting it to the bus stations as well as the metro platform above. The platform above serves as a single surface for movment whichis guided to some extent by the structure, this single island platform facilitates the provision of common services and helps in better functionality and easier orientation.

STRATEGIES 1. CLOSING THE EXISTING GAPS AND RAISING THE MALL’S SIDEWALK IN ORDER TO RESTRICT TWO WHEELERS FROM ENTERING, INTEAD, A BIG COMMON ENTRANCE IS PROVIDED FOR BUSES, PEDESTRIANS AND TWO WHEELERS. THE ENTRANCE TO THE UNDERGROUND IS PROVIDED (GATE 1) 2. FOR BETTER ROAD LEVEL CROSSING AND ENTRANCE TO THE METRO PLATFORM, A GATE TO THE UNDERGROUND IS PROVIDED WITH A DROP OFF FACILITY. 3. WITH THE SMART CITY PROPOSED, THIS BECOMES THE MOST IMPORTANT NODE, THUS A PAVILION WHICH CAN HOST VARIOUS PUBLIC ACTIVITIES, AND TOILET FACILITIES. THIS CATERS BOTH TO THE COMMUTERS AS WELL AS THE GENERAL PUBLIC. 4. AS PER FUTURE PLANS OF THE ASHRAM TRUST FOR PUBLIC RECREATION FACILITIES, THE GATE 4 ACTS AS A THRESHOLD SPACE.

By identifying activity nodes around the site, interventions like plazas and pavilions are provided for people’s appropriation. This pavilion acts as an important place with shade suring the daytime, and highlights the entrance to the metro. During the night time , this place serves as a generic food court for the people from the surrounding neighbourhood. Given the habit of the people of Ahmedabad to eat out in the open as a recreational activity at places like Manekchowk and Lawgarden, this pavilion will go on to serve as a landmark of the people of the locality.

The basement serves as the fulcrum, as the intersection and point of convergence of the polarities of the site, with each of the access points of the basement located in a manner so as to allow a smooth flow of pedestrian movement accross the site. It serves as the market place catering to the people of neighbhourhood as well as the commuters providing for daily amenities making travel easy and efficient.
