ASHWIN - DANISH - SUHAIL - ZARINA - VASIL

2. ● The Chennai Metro is a rapid transit system serving the city of Chennai, Tamil Nadu, India
● It is the third largest metro system in India after Delhi Metro and Hyderabad Metro
● The system has a mix of underground and elevated stations and uses standard gauge.
● Large-scale urbanization and rapid growth of vehicles population has laid severe
stress on urban transport system in city. The sharing of limited right of way by a
variety of modes and other utility services has resulted in traffic congestion,
accidents, inadequate parking area and environment deterioration.
● The usage of private modes is growing unabated mainly due to inadequate and
inconvenient public transport facilities with poor level of service.
● The Phase 1 of Chennai metro covers 54 km in three corridors including Extension.
Presently a total metro network of about 35 km is operational in the city. With a view
of augmenting the mass transit system in addition to the existing public
transportation and Phase-I Metro rail system
● As of November 2019, about 121,000 people use the service on a daily basis. There are
42 trains with four coaches each, making a total of 168 coaches, operating in the first
phase.
INTRODUCTION

3. ● The proposal includes
developing walkways along
the Buckingham Canal and
creating four subways 40
metres wide. The four
subways would be built above
the roof of underground
Chennai Metro stations, but
still be four metres
underground.

4. CHENNAI CENTRAL PAST - PRESENT

5. ● The square will have a multi-storied parking lot at its
basement, which will also form the foundation of the
complex. The 3-storied parking lot will have a
capacity to accommodate 1000 cars.The total area of
the square will be 154,950 sq meters. A
150-meter-tall, 33-storey building will mark the center
of the square
● The Parking of central square is connected to
chennai central metro station
● The space around the plaza as well as in front of
Ripon Buildings and Moore Market Complex will be
landscaped, with lawns, shrubs, benches and
pathways for people to go on a stroll. Two big
pedestrian subways connecting the Central railway
station with Rajiv Gandhi Government General
Hospital and Flower Bazaar will be built as part of the
square
PARKING AT CENTRAL SQUARE

6. Revamping Victoria Hall
● The Chennai Corporation will start
work on revamping the Victoria Public
Hall next month. At least 5.5 acres of
land will be landscaped by the civic
body, following the handing over of the
land by the Chennai Metro Rail Limited
(CMRL). “CMRL work on the premises
of the Victoria Public Hall is in its final
stages. They will hand over the land to
the Corporation in one month
● Work on restoring the Victoria Public Hall
started in 2009, and was delayed owing
to Metro work in the last 10 years. The
Victoria Public Hall will then be used as
a town hall for gathering of residents’
welfare associations to discuss civic
issues.

7. Pedestrian & Disabled Friendly Design:
● To promote walking a minimum of 1.2m wide footpath has been
proposed on the local roads whereas a continuous footpath of 2m
width is proposed on the major roads to provide accessibility to
people on wheelchairs.
● Wherever entry/exit is proposed on the footpath area, it has been
ensured that minimum 3m width is left for walking.Junctions and
intersections are proposed with proper pedestrian crossings. Inthe
design, table top crossings has been proposed wherever
possible,otherwise ramps with gentle slope ranging from 1:5-1:7
have been designed for pedestrians and wheelchair users.
● Proper road markings, Traffic Signages, Zebra crossings and
pedestrian signals are proposed to provide safe and uninterrupted
pedestrian movement
● Design considerations like ramps for wheelchair movement, lifts
have been proposed in the station design for ease in movement of
physically challenged

8. ● The construction posed a challenge from the time
work to build the station began. Extreme variation
in the soil strata, excavation under several heritage
structures, multi-storeyed buildings with shallow
foundation, railway tracks and Buckingham Canal
slowed down construction. There was a thick layer
of rock, under a layer of loose soil below the road
level, which had to be cut and covered with curved
concrete slabs that formed the rings of the tunnels.
The concourse level was built around a different
type of loose soil, while the upper and lower decks
were built on rocks. The mixed soil strata
drastically reduced the average speed of tunnel
boring on the stretch.
● At one point, engineers took more than six months
to excavate a 300 m stretch between Rajiv Gandhi
Government General Hospital and Chennai Central
due to rocky soil condition. Engineers did not apply
more pressure while drilling through the rocks as it
would have affected the weak structures as well as
heritage buildings on the road.

9. CONCEPTUAL SECTION OF CMRL

10. OVERHEAD FOOTBRIDGE FAILURE

11. CENTRAL SQUARE
● The Central Square, Chennai is an upcoming major
intersection proposed by the Government of Tamil Nadu in
Park Town, Chennai. Areas surrounding the Ripon
Building, Victoria Public Hall , Moore market complex ,
Chennai central, the Southern Railway Headquarters and
the Government General Hospital will be developed as
part of the Central Square. Development is estimated to
cost about ₹4 billion (US$56 million) and will be funded by
the CMDA
● The ambitious plan for the Rs.400-crore Central Square
by Chennai Metro Rail Limited was proposed last year and
now the initial design is ready. It will be a seamless transit
hub connecting the outstation trains, MRTS, suburban
services, metro rail and buses. And much of the vast
network will be underground.

12. Underground stations of Chennai Metro
Phase II corridors are proposed with
full height Platform screen doors. The
use of full height Platform screen doors
will reduce air conditioning requirements
of stations.
Thus, ventilation and air
conditioning system is proposed in
following two parts:
Environment Control System (ECS)
Tunnel Ventilation System (TVS)
•One of the major changes that helped in
actualizing the small station concept is
the redesign of the tunnel ventilation
system. This has resulted in the
arrangement of vertical fans, as against
the horizontal fans as proposed in
Phase 1.

13. • Implementation of Multi Modal Integration Strategy
• Formation of Chennai Central Square
• Merger of MRTS with CMRL
Metro Feeder Services by City Bus Transport Operators
• Working Group of CUMTA
• Introduction of Non Motorized Policy
CMRL Initiatives: Towards Better Accessibility

14. MULTI - MODAL TRANSIT STATION
● With six lakh pedestrians passing each day, at the intersection of six rail
corridors in the city - one MRTS, three suburban and two upcoming Metro rail
corridors, this project encourages pedestrian movement by creating clear,
direct and short routes between transit modes.
● The idea is to have multi-modal transport system and facilitate as many
pedestrians as possible to use underground facilities to cross the busy roads.
● The square and the plaza are expected to link all modes of transport including
suburban, MRTS and metro rail services, outstation train services, private
and government local and outstation buses.
● Once the square comes up, passengers alighting from any train or bus could
have easy access to other transport facilities for their onward journeys either
through walkways or pedestrian subways.
● They can also park their vehicles in the underground parking facility before
they board a train or bus to travel outstation.

15. MIXED USE DEVELOPMENT
● The main part of the Central Square is , the Central Plaza, a 20-storey
building with bus bays for private and government buses, passenger
amenities, shopping area and office space.
● Vertical type of mixed use development like
residential land use over the commercial places so
that the distances between the activities is
decreased.
● A three-level underground parking that could
accommodate more than 800 cars will take vehicles,
now parked on road corners blocking traffic, off the
road.

16. STREETSCAPE DESIGN
● As a part of the beautification project, the pedestrians can relax on a bench
surrounded by prune lawns and pathways in front of Ripon Buildings or
Moore Market Complex as they watch the bustling traffic on EVR Periyar
Salai.
● Trees and landscaping add interest, ornamentation and continuity between
urban spaces, while contributing to a reduction of air and noise pollution.

17. ARCHITECTURAL VARIETY
● Contains variety of visually appealing building within the first 400m from
station area.
● Buildings with different architectural styles such as Indo-Saracenic,
Neoclassical, Art deco and Gothic revival can be found.
● These variety of structures have stood over time and still holds its
significance and acts as a landmark.

18. Mobility Pattern
● Total No of Vehicles – 4.75 Millions
● Personalized vehicles (two wheelers & cars) account
for close to 40% of the total trips
• The two wheelers constitute 77% of registered motor vehicles
Public Transport Scenario:
• Bus – 4.5 Million trips/day
• Sub Urban rail – 1.0 Million trips /day
• MRTS – Around 0.12 Million trips/day
• Metro – 0.65 Million trips/day (After Phase 1
Network Completion)

19. SKYWALK
● Skywalk is a crossing space and connective tissue
that has a certain height above the ground and
serves as networks of above-grade interconnecting
pedestrian walkways consisting of sky bridges over
streets, second level corridors within buildings and
various activity hubs, such as shops and office
● Skywalk as one of the elements of urban linkage in
its current development not only acts as a space for
crossing but has evolved so that it can also become
a public space that triggers the optional and social
activities. However, to be able to provide meaning
and sense of place for the users, it is necessary to
create a city public space that is not just a "space"
but to be a "place". This proposal being conclusively
Dropped .

25. Merger of MRTS with CMRL
• Total length – 24.5 Km/ 21Stations
• Operational – 19.5 Km/18 Stations
• Integrated with Metroat St. Thomas
Mount
• Phase 1 of CMRL Project approval
includes, theintegration of
MRTS with CMRL
• Tamil Nadu, a first mover in attempting to
implement such an integration
• Detailed Study is under progress

26. ● There is a broad focus on sustainability and
improving public transport throughout
Europe. This includes within cities, between
cities, cross border transport to link regional
and national markets together and for the
freight market.
● Trafalgar Square is a public square in the City of
Westminster, Central London, built around the
area formerly known as Charing Cross.
● The transformation of Trafalgar Square
represents the first phase of the practice’s
Central London masterplan − the culmination of
many years’ work to improve the urban
environment in the heart of the capital. It is the
result of a careful balancing act between the
needs of traffic and pedestrians, the ceremonial
and the everyday, the old and the new

28. INFERENCES OF NEW URBANISM IN CMRL CENTRAL
● Axial urban sprawl can be evidently seen along the Main Corridor adjoining
Chennai Central .
● Smart growth as a functional concept can be evolved here can be evolved
with new proposals such as plaza & squares where Walkability to different
modes of transport nearby .
● Provide variety of transportation choices .
WALKABILITY NEAR CHENNAI CENTRAL
● Walkability as a facility wasn’t fully functional before but in future proposals
And design implementation its been given pivotal importance .
● Ample Pedestrian width with direct access to all major points in the vicinity .
● Safety aspect and hardscapes such as seatings & lights are give physical
sight of the pedestrian .
● As a result more importance to walkability inside the square and central plaza
.

29. IS CMRL CENTRAL UNDER URBAN FRAMEWORK ?
● Present status of Chennai CMRL & neighborhood has social , economic and proximal
advantages but lacks environmental and sustainable at very large scale , which can be
redeveloped in the proposal given .
● High Density poses a major problem here hence controlling vehicles can be hectic but
redirecting walking commuters can be easy .
● Public factors help in creating main source of power & capital .
● All the 3 components of urban space like software , hardware & orgware coexist in & around
chennai central CMRL .

30. KEVIN LYNCH INFERENCES - CMRL
● Better composition of the circulation in the CMRL layout creates a better connectivity
within a complex .
● The integration of transit spaces among the neighbourhood creates a opportunity for
high density commuters .
● Since CMRL acts as a major hub for transportation . Core importance has to be
given to pedestrian to switch between different modes of Transportation .
● Finishing of CMRL will add an contemporary touch to the various existing architectural
styles which brings a visual treat along the central corridor .
● According to jane Jacobs planners are more concerned with automobile movement
and they considered it as the only cause of city decay . But it should be considered as
the symptom but not the root cause .
● Effective transport system can be done by giving hierarchical importance from from
railways to the local access roads and street

31. CONCLUSION / TAKE AWAY
● The essential quality in a good station layout is the provision of adequate
space for efficient movement of passengers between ground level entrances
onto the trains and vice versa in the most direct, simple and logical way.
● Central Metro station acts as the connecting Medium to all transit areas and
circulation of the environment is planned according to it.
● A good urban solution always encourages people to self sustain through
public transports and life revolving around it .
● A TOD pattern is successful when it is flexible and efficiently attracts sufficient
job & residents to create a vibrant, transit supportive place .
