B. Why It’s Used
Paper II §16 of the TGPSC syllabus closes with “Current trends of National and International importance related to infrastructure, transportation, environment, disaster management, rural development, information system and technologies affecting urban and regional planning. Current and emerging concepts-BRTS, MRTS, LRTS, MMTS, NMT, TOD, CNG vehicles, electric vehicles, eco-housing, eco-sanitation, carbon footprint, carbon credits, renewable energies, eco-city and green cites, walkable city, compact city, smart city, inclusive city, resilient city, PURA and SDGs.” This is the broadest single module — every acronym the modern planner is expected to know. The exam tests acronym identification (which mode = what capacity), concept definitions (eco-city vs smart city vs resilient city), and policy frameworks (PURA, SDGs, Smart Cities Mission). Telangana-specific: Hyderabad Metro (MRTS), Strategic Road Development Plan, TS-SPIN (state police modernisation using smart tech), the IT corridor’s transit needs.
C. Mechanism in Words
-
Transit modes are classified by their right-of-way, technology, capacity, and integration. Bus Rapid Transit System (BRTS) — high-capacity buses operating in dedicated, physically segregated lanes (median or kerb-side), with off-board fare collection, level boarding, and priority at signals. Capacity 10,000–30,000 passengers per hour per direction (pphpd); capital cost ~₹15–25 crore/km. Indian examples: Janmarg (Ahmedabad, 2009 — India’s first full BRTS), Delhi BRT (failed; closed), Pune-Pimpri Chinchwad BRT, Indore iBus. Metro Rail Transit System (MRTS / Metro) — heavy rail transit, fully grade-separated, electric, high capacity (30,000–60,000 pphpd); capital cost ₹200–600 crore/km. Indian examples: Delhi Metro (largest), Mumbai Metro, Hyderabad Metro (world’s largest PPP metro), Bangalore Namma Metro, Chennai Metro. Light Rail Transit System (LRTS / Light Rail / Tram) — lighter rail vehicles, often at-grade or partially elevated, lower capacity than metro (5,000–15,000 pphpd), lower capital cost (~₹80–150 crore/km). Indian example: Kolkata tram (heritage); most Indian cities have chosen full metro over LRT. Multi-Modal Transport System (MMTS) — integrated suburban rail + bus + metro network; Hyderabad MMTS (2003) is the named example — a suburban rail service run by Indian Railways + state government connecting Hyderabad, Secunderabad, and surrounding areas.
-
Non-Motorised Transport (NMT) covers walking and cycling — historically neglected but increasingly prioritised. Walking is the dominant mode for short trips in Indian cities (often 30–50% of all trips); footpaths, crossings, signals, and street design determine walkability. Cycling has declined in many Indian cities (scooters and motorcycles replaced cycles); but cycling is making a comeback with cycle tracks, cycle-sharing schemes (smart-bike), and NMT corridors (e.g., the Sabarmati Riverfront in Ahmedabad; Mumbai’s cycling initiatives post-COVID). NMT design principles: continuous, well-shaded, well-lit, separated from motor traffic, safe at junctions. The Smart Cities Mission has funded many NMT projects; the CEEW (Council on Energy, Environment and Water) and ITDP (Institute for Transportation and Development Policy) are key advocacy bodies.
-
Transit-Oriented Development (TOD) is the planning approach that concentrates high-density, mixed-use development around transit stations to maximise ridership and reduce car dependence. The “5 Ds” of TOD (and good urbanism generally): Density (high enough to support transit — typically ≥ 100 dwelling units per acre near stations); Diversity (mixed land uses — residential, commercial, employment, civic); Design (walkable streets, active frontages, pedestrian priority); Destination accessibility (jobs/housing/retail reachable by transit); Distance to transit (typically 800 m walkable radius around stations). MoHUA’s TOD Policy (2014) and state-level policies (Delhi, Maharashtra, Telangana) operationalise this through FSI incentives near metro stations, parking maximums instead of minimums, mandatory mixed use, and walkable-street design. The Hyderabad Metro stations — especially those along the IT corridor — are intended to drive TOD-style development.
-
Alternative fuels — CNG and Electric Vehicles (EVs) — are key to decarbonising transport. Compressed Natural Gas (CNG) — natural gas compressed to ~1% of its volume; used in vehicles (buses, autos, cars); burns cleaner than petrol/diesel (lower PM, NOx, CO2). Delhi’s 1998 Supreme Court-mandated switch of all public transport to CNG dramatically improved air quality. Indian examples: Delhi Transport Corporation buses, Indore City Bus, many auto-rickshaws across cities. Electric Vehicles (EVs) — powered by batteries or hydrogen fuel cells; zero tailpipe emissions (although upstream electricity may have emissions). FAME India (Faster Adoption and Manufacturing of Electric vehicles in India) — central scheme; FAME I (2015); FAME II (2019) with ₹10,000 crore budget. EV adoption is growing rapidly — electric buses (every major city is piloting), electric three-wheelers, electric cars. Telangana’s EV Policy (2020) targets manufacturing and adoption.
-
The “eco-city” / “green city” family of concepts emphasise environmental sustainability. Eco-city — a city designed to live within its ecological footprint, with renewable energy, closed-loop materials, green buildings, extensive public transit, urban agriculture, and biodiversity. Examples: Masdar (UAE — prototype), Curitiba (Brazil — pioneer of BRTS and green planning). Green city — similar but with more focus on green infrastructure (parks, trees, urban forests, green roofs) and green building rating (IGBC, LEED). The Indian Green Building Council (IGBC) and GRIHA (Green Rating for Integrated Habitat Assessment) provide ratings. Carbon footprint is the total greenhouse gas emissions attributable to a person, organisation, or city, typically in tonnes CO₂-equivalent per year. Carbon credits are tradable certificates representing one tonne of CO₂-equivalent reduced or removed; under the Kyoto Protocol’s Clean Development Mechanism (CDM) and now under Article 6 of the Paris Agreement.
-
The “smart city” concept integrates information and communication technology (ICT) with infrastructure and services. Definitions vary, but a smart city uses sensors, data, networks, and analytics to improve urban services — traffic management, water supply, energy, governance, public safety. The Smart Cities Mission (SCM, 2015) is India’s flagship — 100 cities selected through a competitive process, each with a Special Purpose Vehicle (SPV) to implement area-based and pan-city initiatives. Examples: Ahmedabad, Bhubaneswar, Pune, Surat, Hyderabad not selected (it chose not to compete), but nearby Karimnagar in Telangana was selected. Common smart city components: Integrated Command and Control Centres (ICCC), smart parking, smart street lighting, smart water meters, e-governance apps. Critiques: smart city programmes have been criticised for top-down implementation, focus on IT rather than basic services, and uneven benefit distribution.
-
The “compact city” / “walkable city” concepts emphasise urban form. Compact city — high-density, mixed-use development with clear boundaries (green belt or urban growth boundary); minimises land consumption and trip lengths; supports public transit. The antithesis of urban sprawl. European cities (especially in the Netherlands, Germany, Scandinavia) exemplify compact urban form. Walkable city — designed for pedestrian priority: continuous wide footpaths, narrow streets, mixed uses at ground level, frequent crossings, traffic-calmed zones. Walkability is measured by Walk Score, the Jeff Speck framework, and ITDP’s “People Near Transit” indicators.
-
The “inclusive city” / “resilient city” concepts respond to equity and climate change imperatives. Inclusive city — designed so that all residents (regardless of income, gender, age, ability, caste, religion, language) can access services, livelihoods, public space, and decision-making. Inclusion spans physical accessibility (universal design), affordability (housing, transit, services), social inclusion (no discrimination), and procedural inclusion (participation in planning). Resilient city — designed to withstand and recover from shocks and stresses — physical (earthquakes, floods, cyclones, fires), environmental (climate change, pollution), economic (job losses, financial crises), and social (communal violence, pandemics). The 100 Resilient Cities network (Rockefeller Foundation) pioneered the Chief Resilience Officer role; many Indian cities (including Chennai, Pune, Surat) were members.
-
PURA (Provision of Urban Amenities in Rural Areas), proposed by President APJ Abdul Kalam, addresses the rural-urban divide from the other direction. Rather than bringing rural people to cities (urbanisation), PURA brings urban-style amenities to rural clusters — physical connectivity (roads, power, transport), electronic connectivity (telecom, internet), knowledge connectivity (education, health, skills), and economic connectivity (markets, processing). The central government implemented PURA as a pilot scheme (2004–05); it was restructured and eventually merged into other rural development programmes. PURA’s spirit continues in the Shyama Prasad Mukherji Rurban Mission (SPMRM, 2016) — a programme to develop 300 “rurban” clusters across India with urban-style infrastructure.
-
The Sustainable Development Goals (covered in Lesson 3.1) include SDG 11 — Sustainable Cities and Communities. SDG 11’s targets include: 11.1 adequate, safe, affordable housing for all by 2030; 11.2 accessible, sustainable transport systems for all; 11.3 inclusive and sustainable urbanisation with participatory planning; 11.5 reduce deaths and losses from disasters; 11.6 reduce adverse environmental impact of cities (especially air quality and SWM); 11.7 universal access to safe, inclusive green and public spaces; 11.a support positive economic, social, environmental links between urban, peri-urban, and rural areas; 11.b integrate policies for inclusion, resource efficiency, mitigation, adaptation, and disaster resilience; 11.c support least-developed countries in sustainable building. Planners engage with SDG 11 through NITI Aayog’s SDG India Index, state-level SDG action plans, and ULB-level implementation tracking.
D. Core Concept Explanations
C1. Transit modes — capacity and cost
| Mode | Capacity (pphpd) | Capital cost (₹/km) | Indian examples |

| NMT (walk + cycle) | Variable | Low | Walking is dominant; cycle tracks emerging |
C2. TOD — 5 Ds
| D | Definition |
|---|---|
| Density | High enough to support transit (~100 DU/acre near stations) |
| Diversity | Mixed uses — residential, commercial, employment, civic |
| Design | Walkable streets, active frontages, pedestrian priority |
| Destination accessibility | Jobs/housing/retail reachable by transit |
| Distance to transit | ~800 m walkable radius around stations |

| Cities | 100 (selected competitively) |
| Implementation | Special Purpose Vehicle (SPV) per city |
| Components | Area-based development + pan-city initiatives |
| Telangana city | Karimnagar (Hyderabad chose not to compete) |
| Common projects | ICCC, smart parking, smart lighting, e-governance |
C4. “City concepts” — quick definitions
| Concept | Emphasis |
|---|---|
| Eco-city | Ecological footprint; renewables; closed-loop |
| Green city | Green infrastructure; parks; ratings |
| Compact city | High density; mixed use; boundaries (anti-sprawl) |

E. Worked Numericals and Parameter Tables
E1. TOD density requirement
To support a metro station with 30,000 daily boardings, the surrounding area (within 800 m radius) needs sufficient population and jobs. Catchment area = π × 800² ≈ 2,010,000 sq m ≈ 200 ha. If target is 250 persons + jobs per hectare: catchment pop+jobs = 200 × 250 = 50,000. At 1.5 trips/person/day, demand = 75,000 daily boardings+alightings — supports metro feasibility.
E2. EV emissions reduction
A diesel bus emits ~1.2 kg CO₂/km. An electric bus emits 0 (tailpipe) but consumes 1.1 kWh/km from the grid. At India’s grid emission factor ~0.7 kg CO₂/kWh, electric bus upstream = 1.1 × 0.7 = 0.77 kg CO₂/km. Emissions reduction = 1.2 − 0.77 = 0.43 kg/km ≈ 36% reduction. As the grid decarbonises, EV emissions fall further.
E3. Carbon credit value
A solar power project generates 10,000 carbon credits per year (1 credit = 1 tonne CO₂-equivalent). At ₹1,500/credit: annual revenue = 10,000 × 1,500 = ₹1.5 crore/year. This additional revenue improves project financial viability.
E4. Compact city land saving
A city of 1 million at 50 pph (sprawl) occupies 1,000,000/50 = 20,000 ha = 200 sq km. At 200 pph (compact), it occupies 5,000 ha = 50 sq km. Land saving = 150 sq km — equivalent to substantial preserved open space, farmland, or forest.
F. Design Criteria
| Parameter | Standard / Typical value | Source |
|---|---|---|
| BRTS capacity | 10,000–30,000 pphpd | ITDP / BRT Standards |
| Metro capacity | 30,000–60,000 pphpd | Industry |
| BRTS capital cost | ₹15–25 crore/km | Industry |
| Metro capital cost | ₹200–600 crore/km | Industry |
| TOD walkable radius | ~800 m from station | MoHUA TOD Policy 2014 |
| TOD density target | ~100+ DU/acre near station | MoHUA TOD Policy |
| FAME II budget | ₹10,000 crore | Government of India, 2019 |
| Smart Cities Mission | 100 cities | MoHUA, 2015 |
| PURA proposed | by APJ Abdul Kalam | Year ~2003–04 |
| SPMRM | 300 rurban clusters | 2016 |
| SDG 11 target year | 2030 | UN 2030 Agenda |
