Urban Planning, Morphology, and Sustainable Mobility

Comprehensive vocabulary flashcards covering urban planning concepts, sustainable transport, healthy cities, historical models, sprawl, morphology, zoning, and growth management.

Mobility

A measure of how far, fast, and easily people or vehicles move.

Accessibility

The ability to reach daily needs and destinations safely, affordably, and comfortably.

Active Transport

Human-powered modes of travel, including walking, rolling, cycling, wheelchairs, and e-bikes.

Intermodality

The practice of combining multiple transport modes within a single journey, such as walking and taking a bus.

5Ds of Sustainable Mobility

A built-environment framework comprising Density (people/jobs per area), Diversity (mixed uses), Design (street connectivity and block size), Destination accessibility (reachable opportunities), and Distance to transit (nearby stops).

Transit-Oriented Development (TOD)

A planning approach that clusters compact, mixed-use, walkable development and quality public space around transit stations to reduce car dependence.

Sikkak

Narrow pedestrian alleyways or passages between plots in Abu Dhabi that shorten walking routes through superblocks.

Complete Streets

Streets designed and operated to safely accommodate all users, ages, abilities, and travel modes, prioritizing vulnerable road users and efficient transit while managing cars.

Safe System

A transport safety approach that accounts for human fallibility to eliminate fatal and serious injuries through safe roads, speeds, users, vehicles, and post-crash care.

First/Last Mile

The segment of travel required to get between a transit stop or station and a trip origin or final destination.

Transfer Penalty

The perceived or actual cost in extra waiting time, physical effort, or discomfort that travelers experience when changing between transit modes or lines.

Healthy City

An urban environment that continually improves living conditions, physical spaces, and basic services while fostering partnerships that sustain health, wellbeing, and inclusion.

Health Impact Assessment (HIA)

A formal combination of procedures and methods used to evaluate how a proposed policy, plan, program, or project may affect the health of a population and its subgroups across six stages: screening, scoping, assessment, recommendations, reporting, and monitoring/evaluation.

Green-Blue Infrastructure

Networks of natural and semi-natural landscape elements—such as vegetation, parks, watercourses, and wetlands—that manage stormwater, mitigate urban heat, and enhance ecological and mental wellbeing.

Barcelona Superblocks

An urban design model that clusters a $3 \times 3$ grid of standard street blocks (roughly $400 \times 400\text{ m}$), routes through-traffic to perimeter roads, and transforms interior streets into pedestrian, cycling, and green community spaces.

Health in All Policies (HiAP)

A governance strategy that systematically integrates public health and health equity considerations into decision-making across all public policy and governmental sectors.

Urban Planning

The technical and political discipline of organizing land use, transportation, infrastructure, and urban activities to improve urban life.

Zoning

Legal regulations and ordinances by which local governments control how land is used, developed, and occupied in designated districts.

Garden City

A conceptual model formulated by Ebenezer Howard proposing planned, self-contained communities that integrate town and country living surrounded by permanent agricultural greenbelts.

Neighborhood Unit

An urban design framework created by Clarence Perry that places schools and community services at the center, groups residences around them, bounds the area with arterial roads, and excludes through-traffic from interior streets.

New Urbanism

A planning and development movement emphasizing walkable, compact, transit-oriented neighborhoods with diverse housing types and mixed land uses as an alternative to suburban sprawl.

Urban Sprawl

A pattern of low-density, fragmented, and car-dependent outward urban expansion characterized by strictly separated land uses.

Morris Five Sprawl Characteristics

The defining physical traits of urban sprawl: low density, separated land uses, automobile dependence, disconnected road networks causing congestion, and inadequate public transit.

Spatial Mismatch

The geographical separation between where low-income or marginalized individuals live and where suitable jobs are located, measured by the share of employment situated outside a $10\text{-mile}$ radius from the central business district.

Infill Development

The construction or repurposing of buildings on vacant, underutilized, or previously developed parcels situated within already established urban fabrics.

Urban Regeneration

An integrated strategy that simultaneously delivers physical, social, economic, and environmental upgrades to revitalise an existing urban area.

Urban Renewal

A redevelopment strategy historically centered on large-scale site clearance, demolition, and infrastructure modernization, often resulting in community disruption and displacement.

Retrofitting

Upgrading, adapting, and improving the functional or environmental performance of existing buildings or neighborhoods without undertaking full demolition.

Regeneration Trauma

The adverse community impacts triggered by poorly managed urban redevelopment, including physical displacement, cultural erasure, late top-down planning, and private market capture.

Urban Morphology

The spatial and geographical study of the physical form, structure, and fabric of cities, the processes that shaped them, and how they evolve over time across plots, streets, buildings, and blocks.

Diachronic Analysis

The morphological study of a single geographical location across different historical points in time to identify morphological persistence and structural evolution.

Synchronic Analysis

The morphological comparison of different urban locations observed at the same point in time and at an identical scale to discern similarities and differences.

Lynch's Five Elements

The spatial features proposed by Kevin Lynch that people use to navigate and form mental maps of cities: Paths, Edges, Districts, Nodes, and Landmarks.

Permeability

The extent to which an urban street network provides a choice of accessible, interconnected routes through an area.

Link-Node Ratio

A street network connectivity indicator calculated by dividing the total number of street segments (links) by the total number of intersections or dead ends (nodes), with values above $1.4$ representing high connectivity.

Police Power

The legal and constitutional authority of government to enact regulations that safeguard public health, safety, morals, and general welfare.

Comprehensive Plan

A long-range statutory policy document that coordinates future land use, housing, transportation, infrastructure, and environmental systems across an entire municipality.

Euclidean Zoning

A traditional regulatory practice that segregates incompatible land uses into distinct geographic districts, which protects against nuisances but can increase car dependence and sprawl.

Floor Area Ratio (FAR)

A zoning formula measuring building bulk and development intensity, calculated by dividing the total building floor area by the gross plot area.

Urban Network Analysis (UNA)

An analytical spatial modeling framework that evaluates street networks and building plots using reach, gravity, straightness, betweenness, redundant paths, and closeness.

Pedestrian Route Directness (PRD)

A GIS network metric expressed as the actual network travel distance divided by straight-line Euclidean distance; higher values denote greater detours.

Growth Management

A set of regulatory, financial, and planning policies designed to guide where, when, and how urban development occurs to match public infrastructure capacity.

Urban Growth Boundary (UGB)

A designated planning line intended to contain municipal outward expansion, concentrate development inside existing centers, and protect surrounding rural land from sprawl.

Concurrency

A regulatory growth management mandate that conditions development approval on the documented availability of adequate infrastructure and municipal services.

Impact Fees

Financial exactions charged to developers by local governments to help pay for off-site public infrastructure capacity necessitated by new development projects.
