Transit-Oriented Urban Design for the 500 m Influence Zone of a Namma Metro Interchange, Bengaluru

This M.Arch thesis designs the 500-metre influence zone around a Namma Metro interchange station in Bengaluru as a transit-oriented neighbourhood. Metro stations in the city have been built fast, but the areas around them still work as if the metro did not exist: long compound walls, missing footpaths, surface parking, auto-rickshaw scrums at the exit, and low-rise plots that cannot add homes or jobs near the station. People who could walk ten minutes to the metro instead take a two-wheeler.

The thesis uses the National Transit Oriented Development Policy 2017 and the Metro Rail Policy 2017 of the Ministry of Housing and Urban Affairs, the URDPFI Guidelines 2015, and the ITDP TOD Standard as its policy base. It maps the existing zone in QGIS — land use, building footprints, plot sizes, street network, block size, footpath continuity, and walking catchments along the real street network — and scores it against TOD principles: walk, cycle, connect, transit, mix, densify, compact and shift.

The design proposes a station-area plan with a new pedestrian and cycle network, a multimodal interchange plaza, active street edges, a density and mixed-use framework tested as three FAR scenarios in Rhino/Grasshopper, and detailed urban design for two key streets and the interchange plaza. Deliverables are an urban-design framework, design guidelines, street sections, a 1:1000 area model and a 1:200 plaza model, defended before an external jury.

Abstract

Bengaluru's metro network is expanding quickly, yet land around stations remains car- and two-wheeler-oriented. National policy asks cities to plan the 500–800 m around stations for higher density, mixed use and walking. This thesis translates that policy into an urban-design proposal for one interchange station's influence zone, demonstrating how streets, plots and public spaces can be reorganised so that walking and cycling to the metro become the obvious choice.

Introduction

The chosen zone (the station is not named in this bundle; the student selects one) combines older residential layouts, a commercial arterial, a few large institutional campuses and vacant or under-used government land. Interchange stations attract the heaviest footfall and the worst congestion at their exits, making them the most demanding test case for TOD.

Literature review and gap

Peter Calthorpe's work defined the TOD idea of compact, walkable development around transit; Jan Gehl's work on public life gives methods to observe how people actually use streets; the ITDP TOD Standard converts principles into measurable indicators. Indian policy documents set targets but leave the design of individual station areas to cities. Published Indian studies are mostly policy critiques or city-scale analyses; few show a plot-by-plot, street-by-street design for a real station area with density scenarios tested against infrastructure and open-space norms. This thesis addresses that gap.

Existing condition vs proposed approach

• Existing: large blocks, discontinuous footpaths, gated campuses blocking short-cuts, surface parking, informal feeder stops, uniform low FAR regardless of distance from the station.
• Proposed: a fine-grained pedestrian network with new through-block links, continuous shaded footpaths and cycle tracks, an organised feeder interchange for buses, autos and cabs, active frontages, graded density and mixed use highest near the station, and managed parking.

Feasibility

• Technical: all analysis uses open data (OpenStreetMap, Bhuvan imagery) plus the student's own surveys; tools are QGIS and Grasshopper.
• Regulatory: the proposal works within the national TOD policy's recommendations and suggests changes to local development regulations as an influence-zone overlay.
• Social: the design keeps existing street vending and adds space for it, and avoids displacement by using under-used public land first.

Metro stations in Bengaluru are surrounded by urban form that discourages people from walking to them. Blocks are large and fenced, footpaths are broken or occupied, feeder transport clusters chaotically at exits, and development regulations do not allow more homes and jobs close to the station than far from it. The result is under-used transit capacity, congestion at station entries, and continued dependence on private vehicles despite large public investment in the metro.

National policy recommends compact, mixed-use, walkable development in station influence zones, but there are few worked examples of what this means for a specific Indian station area. The problem this thesis addresses is: how can the 500 m influence zone of a metro interchange be redesigned — its streets, blocks, plots and public spaces — so that walking, cycling and feeder transit become the dominant ways of reaching the station, while density and mixed use increase within the capacity of infrastructure and open space?

In scope

• The 500 m influence zone around one interchange station, with a context study to 800 m.
• Urban-design framework: movement, land use, density, open space, built form.
• Detailed design of the interchange plaza and two streets at 1:500 and 1:200, with sections at 1:100.
• Design guidelines for plots (setbacks, frontage, height, parking) inside the zone.

Out of scope

• Architectural design of individual buildings beyond massing.
• Traffic micro-simulation; movement is analysed with network analysis, counts and design standards.
• Financial modelling of land value capture beyond a qualitative discussion of policy tools.
• Statutory amendment of the master plan.

The thesis runs over two semesters as a research-by-design study.

Methods: document review, GIS spatial analysis, network analysis, direct observation and counts, intercept interviews, comparative precedent analysis and scenario testing. Results are reported as the student's own measured values, never borrowed figures.
