Urban Transport & Planning

Transport is central to urban life — it determines how easily people can access jobs, education, healthcare, and leisure. For AQA GCSE Geography, you need to understand the transport challenges facing cities in both HICs and LICs/NEEs, and evaluate strategies for making urban transport more sustainable.

Why Is Urban Transport Important?

• Economic productivity: Efficient transport allows workers to reach their jobs and businesses to move goods.
• Social inclusion: Good transport gives people access to education, healthcare, and social networks.
• Environmental impact: Transport is a major source of CO2 emissions, air pollution, and noise pollution.
• Quality of life: Long commutes, traffic congestion, and poor air quality reduce wellbeing.

In the UK, transport accounts for approximately 27% of total CO2 emissions — the largest single source.

Transport Challenges in HICs

Traffic Congestion

Traffic congestion is a major issue in almost every large HIC city:

City	Average commute time	Key issue
London	~40 minutes (one way)	Overcrowded Tube; road congestion
Los Angeles	~55 minutes	Car dependency; limited public transport
Tokyo	~48 minutes	Overcrowded trains (200% capacity at peak)

Causes:

• High car ownership — most HIC households own at least one car
• Urban sprawl — low-density suburbs require car travel
• Inadequate public transport in suburban and rural-urban fringe areas
• Peak-hour concentration — most travel occurs during short morning and evening peaks

Effects:

• Economic cost — congestion costs the UK economy an estimated £8 billion per year
• Air pollution — vehicles emit nitrogen dioxide (NO2), particulate matter (PM2.5), and CO2
• Health impacts — stress, respiratory disease, road traffic accidents
• Environmental damage — habitat fragmentation, noise pollution

Public Transport Pressures

Even cities with good public transport face challenges:

• Overcrowding on trains and buses during peak hours
• Ageing infrastructure — London's Tube was built in the 1860s; many lines need major upgrades
• High fares — London has some of the most expensive public transport in the world
• Unequal access — suburban and peripheral areas are often poorly served

Transport Challenges in LICs and NEEs

Transport challenges in LIC and NEE cities are fundamentally different:

Rapid growth outstripping infrastructure

• Cities like Lagos, Dhaka, and Mumbai have grown so fast that transport infrastructure cannot keep up
• Roads are often unpaved, narrow, and poorly maintained
• Traffic management systems (traffic lights, lane markings, one-way systems) may be absent or ignored

Congestion in LIC/NEE cities

City	Average commute time	Key issue
Lagos	3–4 hours (each way)	Severe congestion; limited road capacity
Mumbai	~90 minutes	Overcrowded trains (4x capacity)
Dhaka	2–3 hours	Limited road network; flooding disrupts transport

Informal transport

In many LIC/NEE cities, the gap left by inadequate public transport is filled by the informal transport sector:

• Minibuses/shared taxis: Danfos in Lagos, matatus in Nairobi, jeepneys in Manila
• Motorcycle taxis: Okadas in Lagos, boda-bodas in Kampala
• Cycle rickshaws: Common in South Asian cities
• These services are flexible and affordable but often unsafe, unregulated, and polluting

Strategies for Sustainable Urban Transport

1. Bus Rapid Transit (BRT)

BRT systems use dedicated bus lanes, pre-paid boarding, and high-capacity vehicles to provide fast, reliable public transport at a fraction of the cost of building a metro system.

City	BRT Details
Curitiba, Brazil	Pioneered BRT in the 1970s; 2 million passengers/day; tube-shaped stops
Lagos, Nigeria	BRT-Lite launched 2008; 200,000+ passengers/day; reduced commute times by ~30%
Bogota, Colombia	TransMilenio system; 2.4 million passengers/day; dedicated lanes on major arterial roads
London, UK	Not a full BRT but has dedicated bus lanes on key routes

Exam Tip: BRT is a favourite AQA exam topic because it is relevant to both HICs and LICs/NEEs. Curitiba's BRT is the classic example, but Lagos's BRT-Lite shows it can work in a very different context.

2. Metro and Rail Systems

• London Underground: The world's oldest metro (1863); 272 stations; carries ~5 million passengers/day
• Elizabeth Line (Crossrail): Opened 2022; connects Heathrow to east London; reduces congestion on existing lines
• Lagos Rail Mass Transit: Blue Line opened 2023; planned to reduce road congestion
• Delhi Metro: Opened 2002; now has 12 lines; carries ~6 million passengers/day; has reduced car use and emissions

3. Congestion Charging

London Congestion Charge (introduced 2003):

• £15/day charge for driving in central London (Zone 1)
• Reduced traffic in the zone by approximately 30% in the first year
• Revenue is invested in public transport improvements
• Critics argue it disproportionately affects lower-income drivers and small businesses

Other examples: Stockholm, Singapore, Milan all operate congestion charging or road pricing schemes.

4. Cycling Infrastructure

City	Cycling Details
Copenhagen, Denmark	62% of residents cycle to work; 400 km of segregated cycle lanes
Amsterdam, Netherlands	More bicycles than people; cycling accounts for 38% of all trips
London, UK	Santander Cycles scheme; expanding "Cycleway" network; but cycling remains ~5% of trips
Freiburg, Germany	400 km of cycle paths; 27% of trips by bicycle

5. Pedestrianisation

• Converting roads to pedestrian-only zones reduces traffic, improves air quality, and creates more pleasant urban spaces
• Examples: Times Square (New York), Exhibition Road (London), Stroget (Copenhagen)
• Can increase footfall and spending in shops and restaurants
• Concerns: access for deliveries, disabled people, and emergency vehicles

6. Car-Free Zones and Low Traffic Neighbourhoods (LTNs)

• Vauban, Freiburg: Residential car-free district; cars parked on the periphery
• Pontevedra, Spain: City centre has been car-free since 1999; pedestrian casualties dropped to zero; CO2 emissions fell 70%
• London LTNs: Introduced during COVID-19 and expanded since; controversial — reduce rat-running but can increase traffic on boundary roads

Evaluating Transport Strategies

No single transport strategy is perfect. Each has advantages and disadvantages:

Strategy	Advantages	Disadvantages
BRT	Low cost; quick to build; flexible	Lower capacity than metro; still uses roads
Metro/Rail	High capacity; fast; reduces road congestion	Very expensive; takes years to build
Congestion charge	Reduces traffic; raises revenue	Regressive (hits low-income drivers); displacement of traffic
Cycling	Zero emissions; healthy; cheap	Limited by weather, terrain, and safety concerns
Pedestrianisation	Improves air quality and public space	Reduces access for vehicles; can displace congestion
Car-free zones	Dramatic environmental and health benefits	Controversial; difficult to retrofit in existing cities

Exam Tip: In a 9-mark question about transport, evaluate at least two strategies. For each, explain how it works, give a specific example, discuss advantages, and identify limitations. Conclude by stating which strategy you think is most effective and why.
