Urban Planning Definitions Flipbook – Expert Terms (Part 3 of 3)
U. Research Methods & Survey Design (T201–T210)
Key terms for thesis, dissertations and empirical urban research.
A research hypothesis is a clear, testable statement predicting the relationship between two or more variables in a planning study (for example, “proximity to parks is positively associated with children’s physical activity”).
Operational definition specifies exactly how a concept is measured or observed in a study (for example, accessibility measured as minutes of walking time to the nearest bus stop).
Sampling frame is the list or database of units (households, individuals, schools, plots) from which the sample is actually drawn in a survey.
Stratified sampling divides the population into homogeneous sub-groups (strata) such as income group or zone and selects samples from each, to improve representation and precision of estimates.
Cluster sampling selects groups of units (for example, blocks, wards, slums) as clusters, and then surveys all or some units within selected clusters, useful when population is spread over a wide area.
Pilot survey is a small-scale trial run of the questionnaire with a few respondents to check clarity, timing, sequence and reliability before the main survey is conducted.
Reliability refers to the consistency or stability of a measurement tool—if repeated under similar conditions, it should produce similar results (for example, Cronbach’s alpha for scales).
Validity indicates whether an instrument actually measures what it is intended to measure—content validity, construct validity and criterion validity are important in planning surveys and indices.
Cross-sectional study collects data at one point in time from different respondents, useful to describe current conditions or associations between variables but not causal directions over time.
Longitudinal or panel study follows the same units (households, children, neighbourhoods) over time to track changes and infer dynamic relationships, such as impact of new infrastructure on behaviour.
V. Health, Equity & Well-being (T211–T220)
Planning concepts linking environment, access and public health.
Health-impact assessment systematically evaluates how a plan, policy or project may affect population health and health inequalities, and recommends design or mitigation to enhance positive impacts.
Environmental justice means that no group of people, especially the poor or marginalised, should bear disproportionate environmental burdens or have reduced access to environmental benefits like parks or clean air.
Food desert is an urban area where residents have limited physical and economic access to affordable, nutritious food, often due to absence of markets, especially affecting low-income neighbourhoods.
Walkability index is a composite measure describing how friendly an area is for walking, typically based on land use mix, density, street connectivity, footpath quality and safety indicators.
Active travel refers to walking, cycling and other non-motorised modes used for daily trips to work, school or errands, supported by planning through safe networks and mixed land use.
Health equity means that everyone has a fair opportunity to attain their full health potential, and no one is disadvantaged from achieving this potential because of social or spatial conditions such as neighbourhood, income or gender.
Social determinants of health are conditions in which people are born, grow, live, work and age—such as housing, transport, education and environment—that strongly influence health outcomes and are shaped by planning decisions.
Mental well-being refers to positive psychological health, which can be supported by planning through quiet green spaces, social interaction opportunities, reduced noise and stress-reducing environments.
Age-friendly city ensures that urban environments, services and opportunities are designed to support older persons—barrier-free access, benches, safe crossings, health facilities and social participation spaces.
Health-sensitive land use planning explicitly considers health impacts when deciding locations of schools, industries, parks, liquor outlets and traffic corridors, to reduce exposure to hazards and promote healthier choices.
W. Economic & Industrial Planning (T221–T230)
How planning interacts with economic structure, employment and industry.
Economic base of a city consists of export-oriented or basic activities that bring income from outside (for example, manufacturing, IT, tourism), supporting non-basic local services and overall urban growth.
Industrial location theory explains where industries choose to locate based on transport cost, labour, raw materials, markets and agglomeration advantages, informing zoning and infrastructure planning.
SEZ is a notified area with special fiscal and regulatory incentives to promote exports, investment and employment, often planned with dedicated infrastructure and simplified procedures.
Industrial estate is a planned cluster of industrial plots and sheds with shared infrastructure such as roads, power, water and effluent treatment, to promote organised industrial development.
Agglomeration economies are cost and productivity advantages gained when firms locate near each other, due to shared suppliers, skilled labour, knowledge spillovers and large markets, influencing spatial planning of economic zones.
Informal economy cluster is a concentration of informal activities—like home-based garment work, small workshops or markets—often not formally recognised in zoning but crucial for livelihoods and requiring supportive planning approaches.
Service sector-led growth refers to urban economies dominated by services such as IT, finance, education and health, which create different land use, skill and infrastructure demands compared to manufacturing-led cities.
KBUD focuses on universities, R&D, innovation hubs and creative industries as key drivers of urban economic development, requiring specialised land use, housing and public spaces for knowledge workers.
Employment density is the number of jobs per unit area (for example, jobs per hectare) in a zone, used to estimate travel demand, transit capacity and supporting land use-balance in plans.
Polycentric urban region is an area with several cities or towns of comparable importance, linked by strong economic and commuting ties, where planning aims to distribute growth and avoid dominance of a single core city.
X. Utilities, Logistics & Energy (T231–T240)
Backbone systems that make a city function daily.
Utility corridor is a reserved strip of land (often along roads) where multiple utilities like water mains, sewers, power cables and telecom ducts are laid in an organised, accessible manner for maintenance and future expansion.
Non-revenue water is the difference between water put into the distribution system and water billed to consumers, including losses due to leaks, theft and metering inaccuracies, a key efficiency indicator in planning improvements.
Sewerage refers to the system for collection and conveyance of wastewater (domestic and industrial effluents), while stormwater drainage handles rainwater runoff; both require separate planning though often integrated spatially.
ISWM is a holistic approach combining waste reduction, segregation, recycling, composting, energy recovery and sanitary landfilling, planned together to minimise environmental impacts and maximise resource recovery.
Last-mile connectivity is the final segment of travel or delivery from a transport network node (such as metro station or logistics hub) to the user’s destination, crucial for service quality and mode choice in planning.
Urban freight or city logistics planning focuses on movement of goods within cities—location of warehouses, loading bays, time-windows and truck routes—to reduce congestion, emissions and conflicts with passenger traffic.
Distributed energy systems generate power close to the point of use (for example, rooftop solar, micro-grids), reducing transmission losses and increasing resilience, relevant for planning building codes and layouts.
Energy-efficient urban form is a spatial structure—density, orientation, street pattern and building layout—that minimises overall energy use for transport, cooling and lighting, for example, compact mixed-use with good transit.
Smart metering uses digital meters and communication networks to record and transmit electricity or water consumption in near real-time, enabling demand management, leak detection and more accurate billing by utilities.
Resilient infrastructure design ensures that utility networks like power, water and communication can continue functioning or quickly recover during and after shocks such as floods or storms, by redundancy, elevation and backup systems.
Y. Mega-projects, Corridors & New Towns (T241–T250)
Large scale, strategic development concepts often asked in exams.
Mega-project is a large, complex, and capital-intensive project such as metro systems, expressways or new townships that significantly transform urban form and require multi-agency coordination and risk management in planning.
Transport or economic corridor is a linear region organised around a high-capacity transport route (such as highway, rail, freight corridor) along which industrial, logistic and urban growth is strategically guided by planning policies.
New town is a planned settlement developed on a previously undeveloped site to accommodate population and employment, designed with its own land use, transport and infrastructure systems rather than incremental city expansion.
Satellite town is a smaller independent town near a major city with its own employment base, whereas dormitory town mainly provides residential areas for commuters working in the main city, with limited local jobs.
TCD is planned, higher intensity and mixed-use development along major public transport routes (such as BRT, metro corridors) with appropriate street design and feeder systems to capture transit benefits and shape growth patterns.
Land value capture refers to mechanisms by which government recovers part of the increase in land values created by public investments (like metro stations or highways) through tools such as betterment levy, impact fees or TDR.
Phased development means implementing a new town or large greenfield area in planned stages, synchronising infrastructure with demand, managing financial risk and allowing learning from earlier phases to refine later ones.
Brownfield redevelopment involves transforming previously developed or contaminated sites—like old industrial areas—into new mixed-use or infrastructure projects, often located along strategic transport corridors to reuse land assets.
SIR or corridor node is a large, delineated area planned for intensive industrial, logistic and urban development as part of a wider industrial or freight corridor, with dedicated governance and infrastructure frameworks.
Impact assessment of mega-projects evaluates their environmental, social, economic and spatial consequences—such as displacement, traffic, ecological loss and regional imbalance—to guide approval conditions and mitigation strategies.
Z. International & Contemporary Concepts (T251–T260)
Ideas like New Urbanism, smart growth, compact city etc. that often appear in theory questions.
Smart growth is a planning approach promoting compact, transit-oriented, walkable, mixed-use development, protection of open space and reinvestment in existing communities instead of sprawl at the periphery.
New Urbanism is an urban design movement favouring traditional neighbourhood structures—compact blocks, mixed land uses, walkable streets and varied housing types—over car-oriented suburban sprawl and single-use zoning.
Urban sprawl is low-density, car-dependent, leapfrog development at the urban fringe, characterised by single-use zoning and high infrastructure cost per capita, widely criticised for environmental and social impacts.
Creative city concept views culture, arts and creative industries as drivers of urban regeneration and competitiveness, emphasising support for creative clusters, public spaces and tolerant, diverse environments.
Inclusive city ensures equal access to opportunities, services, space and decision-making for all groups—especially women, children, persons with disabilities and the urban poor—reducing spatial and social exclusion through planning action.
Compact city strategy seeks to concentrate development within existing urbanised areas by promoting higher densities, infill, brownfield reuse and transit-oriented development instead of extensive outward expansion.
Smart city combines technology, good governance, data-driven decision making and citizen participation to enhance quality of life, economic competitiveness and environmental performance, not limited only to gadgets and sensors.
Resilient city is one that anticipates, absorbs, adapts to and recovers from shocks and stresses—such as climate impacts, economic crises or pandemics—while maintaining essential functions and learning from experiences.
Urban metabolism conceptualises the city as a system of flows of energy, water, materials and waste, analysing inputs and outputs to design more circular, resource-efficient urban systems.
Tactical urbanism uses low-cost, temporary interventions—like pop-up bike lanes, parklets or painted crossings—to test ideas, reclaim public space and build support for longer-term changes in the city.
AA. Indicators, SDGs & Indices (T261–T270)
Measurement tools linking local planning to national and global targets.
Indicator is a quantifiable variable used to track progress towards a target—for example, percentage of households with piped water, share of trips by public transport or per capita green space in a city.
Input indicators measure resources used (funds, staff), output indicators measure immediate products (kilometres of road built), and outcome indicators measure changes in conditions or behaviour (reduced travel time, fewer accidents).
SDG 11 aims to make cities inclusive, safe, resilient and sustainable, with targets on housing, transport, heritage protection, disaster risk reduction, environmental quality and public spaces, closely linked to urban planning practice.
Composite index combines multiple indicators into a single score using normalisation and weighting—for example, a livability index or accessibility index—to compare neighbourhoods or cities in a concise way.
Weighting is the assignment of relative importance to different indicators when aggregating them into a composite index, using expert judgement, statistical methods or policy priorities to reflect their contribution to the concept measured.
Urban livability index rates cities based on quality of life domains such as housing, environment, mobility, public services, safety and economic opportunities, used for benchmarking and policy focus in planning exams and practice.
EPI is a composite measure that ranks countries (and sometimes cities) on indicators of environmental health and ecosystem vitality, useful for contextualising national and urban environmental performance in planning discussions.
City-level SDG monitoring dashboard is a visual platform showing current values and trends of SDG-related indicators for a city, helping planners, administrators and citizens track progress and prioritise interventions.
Benchmarking compares performance indicators (for example, water coverage, waste collection efficiency) of one city to other cities or normative standards, to identify gaps and good practices in service delivery and planning.
Baseline study is an initial assessment of conditions and indicators before project implementation, against which future changes and impacts are measured during monitoring and evaluation.
AB. Participation, Behaviour & Social Planning (T271–T280)
Soft side of planning: community, behaviour and micro-politics of space.
Participatory planning actively involves citizens, community groups and stakeholders in analysing problems, generating options and choosing priorities, going beyond token consultation to shared decision-making where possible.
Social mapping is a participatory technique where community members draw maps showing households, facilities, vulnerable groups and social relations, providing planners with local knowledge about space and inclusion gaps.
Behavioural insight uses findings from behavioural science (for example, nudges, biases, heuristics) to design policies and environments that make desired behaviours—like using public transport or segregating waste—easier and more attractive.
CBO is a grassroots group formed by residents to pursue common interests—such as slum upgrading, water supply or women’s safety—often partnering with planners and ULBs in project design and monitoring.
Social exclusion describes processes through which certain groups are systematically disadvantaged in access to jobs, housing, services or public space due to their location, identity or institutional barriers, which planning seeks to correct.
SIA analyses the likely effects of a project or policy on people’s lives, livelihoods, culture and cohesion, including displacement, access changes and distribution of benefits and costs across groups in society.
Gender-sensitive safety audit is a participatory evaluation of streets and spaces from the viewpoint of women and other vulnerable users, assessing lighting, visibility, activity, policing and design features related to perceived safety.
Social capital refers to networks, norms and trust that enable cooperation among residents; good planning can strengthen social capital by providing shared spaces and encouraging community interaction and self-organisation.
Participatory budgeting involves citizens directly in proposing, discussing and voting on how a portion of public funds—often at ward level—should be allocated to local projects, enhancing transparency and relevance of spending.
Place attachment is the emotional bond between people and specific places—such as neighbourhoods, parks or streets—shaped by memories, social relations and identity, which planners should respect in redevelopment and relocation decisions.
AC. Housing Finance, Land & Tenure Tools (T281–T290)
Financial and legal mechanisms behind housing and land supply.
Mortgage finance is a long-term loan secured against a house or property, repaid in instalments with interest; availability and terms of mortgage finance strongly influence housing demand and affordability in cities.
Housing microfinance provides small, short- to medium-term loans to low-income households, often without formal land titles, to support incremental improvements or extensions of their dwellings under flexible conditions.
Cooperative housing society is a member-owned legal entity where individuals collectively own and manage housing, sharing responsibilities for maintenance, services and governance under cooperative law and bye-laws.
CLSS provides interest subsidy on home loans for eligible households, effectively reducing EMI and encouraging ownership of formal housing, widely used under PMAY–Urban and similar programmes.
Land title regularisation is the process of granting legal recognition, occupancy rights or titles to residents of informal or encroached settlements, giving security and enabling access to formal services and finance, subject to planning considerations.
Land banking involves acquiring and holding land in advance of development, so that the public agency can guide future land use, supply serviced plots and capture land value increases for infrastructure financing.
Land assembly is the process of bringing together multiple small land parcels into a larger contiguous site needed for infrastructure, public facilities or redevelopment schemes, achieved through acquisition, pooling or negotiation mechanisms.
Rent control or rent regulation consists of legal limits on rent increases and eviction conditions to protect tenants, but if poorly designed, it may discourage investment and reduce formal rental supply, an important debate for planners.
Inclusionary housing obligation requires private residential projects above a certain size to set aside a percentage of units or floor area for affordable housing or contribute equivalent funds/land, as part of development control or negotiated agreements.
Shared ownership model allows households to buy a share of a dwelling (for example, 50%) while paying subsidised rent on the remaining share, with options to “staircase” up over time, improving access to ownership for low- and middle-income groups.
AD. High-yield Miscellaneous Exam Terms (T291–T300)
Mixed important concepts that frequently appear in objective and theory questions.
Non-conforming use is an existing land use or building that was legal when established but does not conform to current zoning regulations; it is often allowed to continue with restrictions or phased out over time by planning authorities.
FSI incentivisation or premium FAR allows additional floor area beyond base permissible levels in exchange for payment of premium, provision of public amenities or adherence to specific planning objectives like TOD or affordable housing.
Land use compatibility refers to the degree to which different uses can coexist without negative impacts—such as noise, pollution, traffic or privacy conflicts—guiding separation, buffering or mixing decisions in zoning and layout design.
Buffer zone is a strip of land kept free of incompatible development around environmentally sensitive areas (like water bodies) or polluting industries, to reduce risk, protect health and maintain environmental functions.
Street hierarchy is the classification of roads into categories like arterial, sub-arterial, collector and local streets, each with different roles, design standards and access/through-traffic functions within the urban transport network.
Urban land ceiling refers to legal limits placed on the amount of urban land an individual or entity could hold under earlier policies like the Urban Land Ceiling and Regulation Act, intended to prevent land hoarding and support equitable distribution, though often critiqued for implementation issues.
Floor plate efficiency is the ratio of usable or lettable area to the gross floor area of a building floor; high efficiency implies minimal space wasted in cores, circulation and services relative to usable space, relevant in commercial and high-rise projects.
Impact fee is a one-time charge levied on new development projects to cover the additional burden they place on infrastructure and services, for example, roads, water or schools, linking development approvals with infrastructure capacity upgrades.
Statutory plan is legally binding, prepared under specific legislation with enforceable zoning and regulations, while perspective or indicative plan provides a strategic vision and guidance without direct legal enforceability, influencing but not replacing regulatory instruments.
Compliance monitoring is the ongoing process by which authorities verify that construction and land development occur according to sanctioned plans, bye-laws and conditions of approval, using inspections, GIS, remote sensing and digital permit systems to detect violations.
