Puducherry is a city in south of India which has during its history been colonized by Dutch, Portuguese, British and French although its na-tive history has been re-corded since 1st Century AD as a Roman trade destination.

Threat:There is a huge quantity of 2 wheeler traffic and it will keep growing, moreover, as seen in rest of India, more and more people will switch to cars further choking the mobility in the city.

Observation:The old parts of the town are a complete con-trast with the later development, the new areas lack walkability.The new development is chaotic and the streets lack legibility and structure making normal traffic and public transport unpredict-able and worsening pedestrian experience.

Government efforts:The transport body recently conducted a study on behalf of goverment to manage the traffic problem, however the study did not challenge how the need of trips by itself can be reduced. Moreover Pedestrian experience is not just a matter of the correct footpath widths but also the experience of walking which the study did not take into account.

Thesis aim:The thesis aims to suggest urban accupunc-ture interventions which will reduce the mo-torised traffic on streets and encourage pe-destrains and cyclists.The design proposal would be from an Ur-ban-Architecture perspective which will not just deal with easing out pedestrian or other traffic, but would try to reduce the need of commuting itself.

What will the thesis produce:

Steps and strategies to be able to make Puducherry a more pedestrian firendly city along with decongesting some of the streets.

“As long as Engineers are incharge of traffic studies, they will predict the need for engineering. The main problem with traffic studies is that they almost nev-er consider the phenomenon of induced demand.It is a name for what happens when increasing the supply of roadways lowers the time-cost of driving, causing more people to drive.”

ROLE OF CITY FABRIC ON MOBILITY

The way motorized traffic is ditributed onto the streets.

Overlaying the Traffic congestion map, one can see that it is these roads which suffer from slow moving traffic.

worsens

The New blocks are huge and the mobility is pushed to the edges because of discoun-tinous streets inside the block.

The medium sized blocks provide many more streets and intersections in the same area of land enhancing mobility

Plan of Pondicherry in 1788

From 1788 to 1820, the fortification around Pondicherry comes down and road is added.

Instead of continuing the grid, the new settle-ment develops around the road.

Street connectivity is measured by the number of street intersections in a neigh-bourhood. A higher value indicates more intersections and a greater degree of con-nectivity enabling more direct travel between two points using existing streets and

pathways. Walkability Index, Health & Community Design Lab | School of Population and

Public Health

A comparison between Old Puducherry, Piacenza and Prague brings up an interest-ing observation.Piacenza is generally more walkable for an end to end distance viewpoint because of its grid. Prague has more mystery because of its T Junections.However, both cities do not have too many dead ends and the streets connect to other streets. Something that lacks in the new development of Puducherry.

STRATEGY 1Connecting streets, bridging urban boundaries.

Continous streets are commercially viable, hence most activity gets shifted to exterior of neighbourhoods

Urban Accupuncture applied in a few places to allow the streets to become continous.

Continous streets have more commercial value, hence more businesses open up in the interior of the blocks bringing more activities to walkable distances.

STRATEGY 2 Neighbourhood self sufficiency

Merchants have always known that it is all important to be located precisely where people pass by and to have the display window facing the street.

FOR

Existing Area - Low Density

Adapting specific roads for better public transport. Traffic in india can have multiple dimensions, bicycles, auto rik-shaws, pedestrians, buses and cars all ususally have different speeds, this is one of the reasons why Indian roads are infa-mous for overtaking as the lanes are not defined.

Selected roads will be defined to resolve confliction of lanes.

STRATEGY 3Adapting specific roads for better public transport.

No standard width

No standard height

Regulating Pedestrian in-teraction with city edge

Advertising panels dominate the visual quality of the streets bringing chaos.

No standard colour

STRATEGY 4Improving experience of walking.

Different speeds of mobility on an Indian street

Defining clear spaces for Footpath and Parking

Even in cities with high residential densities and great transit systems, ample parking en-courages driving that would not occur without it.

Why does the Puducherry street have a conflict of interest ?

Undefined and Unregulated Spaces Jostling for Space

STRATEGIES APPLIED

Theory of WalkabilityJeff Speck

Useful means that most aspects of daily life are located close at hand and organized in a way that walking serves them well.

Eyes on the streetTraffic restricted internal streets

Safe means that the street has been designed to give pedestrians a fighting chance against being hit by automobiles; they must not only be safe but feel safe.

Interesting means that sidewalks are lined by unique buildings with friendly faces and that signs of humanity abound.

Comfortable means that buildings and landscape shape urban streets

into ‘outdoor living rooms.
