MEVE 016: Unit 13 – Urban Transportation and Energy Conservation
UNIT 13: URBAN TRANSPORTATION AND ENERGY CONSERVATION
13.0 Introduction
Urban transport
systems form the backbone of economic productivity and social interaction in
cities. However, traditional modes of urban mobility have
resulted in traffic congestion, increased fossil fuel consumption, vehicular
emissions, and adverse health impacts. As cities expand, ensuring
energy-efficient, low-carbon, and sustainable urban transport becomes a
critical challenge for urban planners and policymakers.
This unit explores
the interrelationship between urban transport and energy consumption,
identifies core transport challenges, and discusses strategies for achieving
energy efficiency and reducing emissions through better design, alternate
technologies, and sustainable transport models.
13.1 Objectives
After studying this
unit, the learner will be able to:
- Understand the
energy implications of urban transport systems.
- Analyze issues
in inter-city and intra-city transportation.
- Explain the role
of urban structure in transport efficiency.
- Identify
sustainable, low-carbon transport strategies.
- Explore
alternative technologies for energy-efficient human settlement planning.
13.2 Energy
Efficiency and Policy Measures: Systemic Approach to Urban Mobility
13.2.1.1 Urban
Transport & Energy
Urban transport is a
significant consumer of energy, primarily petroleum-based fuels. Cities with
inefficient layouts and poor public transport rely heavily on private vehicles,
leading to higher energy usage and environmental degradation.
- Private vs
Public Transport: Private vehicles are less
energy-efficient per capita than public transport.
- City Design: Compact cities
reduce travel distance and energy use, while sprawled cities promote car
dependency.
13.2.1.2 Transport –
Its Global Contribution to Energy Demand
Globally, the
transport sector accounts for around 25% of energy-related CO₂ emissions,
with urban transport being a major contributor. The majority of urban transport
energy is derived from non-renewable fossil fuels.
- In India, urban
transport accounts for about 18% of final energy use and continues
to grow due to rising urban populations and incomes.
13.2.1.3 Urban
Structure and Efficiency of Various Transport Modes
- Dense, mixed-use
development
enables walking, cycling, and short-distance public transport.
- Low-density
suburban layouts often increase vehicle ownership and
travel distances.
- Energy
Efficiency by Mode:
- Walking and
cycling: Zero emissions.
- Bus Rapid
Transit (BRT): High energy efficiency per passenger-km.
- Cars and
motorcycles: Least energy-efficient.
13.2.1.4 Transport
Sector Emissions and Urban Transport
- CO₂ Emissions: A direct
result of fuel combustion in internal combustion engine (ICE) vehicles.
- Air Pollution: Vehicular
exhaust releases PM2.5, NOx, CO, and unburnt hydrocarbons—causing
respiratory illness and smog.
- Urban Heat
Island Effect: Paved roads and traffic congestion
contribute to rising temperatures.
13.3 Parameters for
Inter-City and Intra-City Transport Issues and Interventions
13.3.1.1 Growth of
Urban Centers
Urban population
growth intensifies pressure on transportation systems. In India, megacities
like Delhi, Mumbai, and Bengaluru face critical congestion and travel
delays due to inadequate and aging infrastructure.
13.3.1.2 Inadequate
Transport Infrastructure
- Poor road design, lack of
pedestrian paths, and limited public transport coverage reduce
efficiency and accessibility.
- Overloaded
systems
lead to delays, energy wastage, and higher emissions.
13.3.1.3 Vehicular
Emission, Pollution and Health Impact
- Emissions from
transport are a leading cause of urban air pollution.
- Chronic exposure
leads to respiratory diseases, cardiovascular issues, and
premature deaths.
- Cities like
Delhi consistently rank among the world’s most polluted.
13.3.1.4 Road Safety
Issues
India has one of the
highest rates of road accidents globally. Contributing factors include:
- Poor traffic
enforcement.
- Inadequate
pedestrian crossings.
- Unsafe road
design.
- Lack of public
awareness.
13.4 Use of Alternate
Technology for Designing Human Settlements
13.4.1.1 Approaches
to Land Use and Transport Planning
- Integrated
Planning:
Align land use with transport systems to minimize travel distances and
encourage public transport.
- Transit-Oriented
Development (TOD): Develop high-density, mixed-use
communities around transit stations.
13.4.1.2 Public
Transport Networks
- Metro Systems: Efficient and
low-emission solution for high-density corridors.
- Bus Rapid
Transit (BRT): Offers rapid service at lower cost than
metros.
- Feeder Services: Last-mile
connectivity via mini-buses, e-rickshaws.
Public transport
significantly reduces energy use per passenger and offers inclusive
mobility.
13.4.1.3 Transport
Energy Consumption and Urban Form
- Compact Urban
Form:
Reduces overall energy consumption by shortening travel distances.
- Sprawled
Development:
Leads to car dependency and higher emissions.
- Mixed-Use
Development:
Enables residents to live near workplaces, schools, and shops, reducing
transport needs.
13.4.1.4 Challenges
and Issues of Transport
- Institutional
fragmentation among agencies.
- Poor data for
planning and evaluation.
- Resistance to
behavior change and public transport adoption.
- Rising
two-wheeler and car ownership in mid-tier cities.
13.5 Sustainable and
Low Carbon Transport
13.5.1.1 Potential
Measures
- Electrification
of Public Transport: EV buses, e-rickshaws, and metro systems.
- Non-Motorized
Transport (NMT) Infrastructure: Cycling lanes, pedestrian
pathways.
- Digital
Solutions:
Smart traffic systems, GPS-based tracking of buses.
- Fuel Efficiency
Standards
and Vehicle Scrappage Policies.
13.5.1.2 Sustainable
Development Benefits of Low Carbon Transport
- Environmental: Lower GHG
emissions and air pollutants.
- Social: Greater access
to opportunities for all income groups.
- Economic: Reduced fuel
import dependence, job creation in clean technology sectors.
- Health: Reduced noise
and air pollution improve urban quality of life.
13.5.1.3 Strategic
Approach for Low Carbon Transport Systems
- Policy
Integration:
Urban planning and transport must work together.
- Incentives for adoption of
EVs and use of public transport.
- Public Awareness
Campaigns:
Promote eco-friendly commuting habits.
- Public-Private
Partnerships (PPP): Encourage investment in infrastructure.
Case Example: Ahmedabad
BRTS and Delhi Metro have significantly reduced travel time, energy
use, and emissions.
13.6 Let Us Sum Up
Urban transportation
is one of the largest energy-consuming sectors in growing cities. A sustainable
future demands integrated solutions that include compact urban planning, public
transit investment, clean energy use, and behavior change.
This unit emphasized
the link between energy consumption and transport patterns, challenges of rapid
urban growth, and potential policy interventions for creating low-carbon,
efficient, and inclusive urban transport systems.
Promoting public
transport, electrification, compact city design, and pedestrian-friendly
infrastructure is essential for future-ready, energy-efficient urban
development in India.
