Title: October 2729, 2005


1
  • October 27-29, 2005
  • Kaliningrad, Russia
  • ENVIRONMENTAL CONSEQUENCES OF MOBILITY
  • Linas Kliucininkas
  • Department for Environmental Engineering
  • Kaunas University of Technology

2
Trends in vehicle kilometers of travel in world
cities, 1960-1990 underlying drivers and policy
responses
  • Vehicle kilometres of travel (VKT) the total
    annual vkt by
  • passenger vehicles.
  • The relative importance of the factors affecting
    changes in vkt
  • FAC PG US CO VO
  • PG - population growth,
  • US urban sprawl,
  • CO car ownership,
  • VO - vehicle occupancy.

Some key land use and transport characteristics
of the seven case study cities

Transport and Energy Challenge for
technology
  • Energy consumption has a strong correlation with
    the level of development.
  • Among developed countries,transportation now
    accounts between 20 and 25 of all the energy
    being consumed.
  • Alternative fuels in the form of non-crude oil
    resources are drawing considerable attention as a
    result of shrinking oil reserves, increasing
    petroleum costs and the need to reduce
    pollutants emission.

Transport and Atmospheric Pollution
Challenge for producers, planners and society
  • Air quality standards are being implemented with
    increasing rigor in more and more countries
    around the world.
  • Two major groups of atmospheric pollutants could
    be seen as contributors to local and global
    effects.
  • Traditionally, the most significant conventional
    emissions are NOx, CO, VOCs, lead and particulate
    matter.
  • Some exhaust emissions from road transport
    give rise also to secondary pollution, such as
    photochemical oxidants.
  • The climate change problem is related to changes
    in the concentration of greenhouse gases, such as
    CO2, CH4, N2O, CFCs.

9
Transport and Noise Challenge for producers,
planners and society
  • Excessive noise levels (65dB(A) and gt) damage
    people health by contributing to high blood
    presure and cardiovascular diseases (OECD, 2001).
  • In OECD countries, around 30 of the population
    is exposed to noise levels higher than 55dB(A).
  • Continuous exposure to noise can lead to
    weakening of the auditory system and sleeping
    disorders. Noise has also negative affects on
    wildlife.

10
Transport and Land Take Challenge
for planners
  • Increased demand for transport is already placing
    enormous pressures for new infrastructures. Many
    of these transport facilities such as airports
    and ports require very large amounts of land for
    their own internal operations and for the
    external transport links that have to be
    provided.
  • While in several areas road transportation
    infrastructures are overused, a situation of
    over-capacity exists in others.

11
Transport in Cities Challenge for urban
planners
  • The geographical growth of cities has not been
    proportional to the growth of population.
  • For the developed world, the preference for road
    transportation has led to a massive consumption
    of space, which ranges between 1.5 and 2.0 of
    the total land surface devoted to the automobile,
    mainly with roads and parking lots.
  • The dependence on transportation has reached a
    point where 30 to 60 of urban areas are taken by
    road transportation infrastructure alone.

12
Traffic Planning
  • Spatial structure
  • Modes of transport

Integrated assessment of environmental impacts
fromtransport and traffic infrastructure
systems COST 350 action
  • Inventory of environmental mechanisms and
    decision-making mechanisms
  • Inventory of traffic and transport
    characteristics
  • Development of environmental impacts integration
    methods (scoring and aggregation)

16
Indicators of Transport and Environment
Integration TERM
  • Is the environmental performance of the transport
    sector improving?
  • Are we getting better at managing transport
    demand and at improving the modal split?
  • Are we optimising the use of existing transport
    infrastructure capacity and moving towards a
    better balanced intermodal transport system?
  • Are we moving towards a fairer and more efficient
    pricing system, which ensures that external costs
    are internalised?
  • (EEA)

17
Indicators of Transport and Environment
Integration TERM
  • How rapidly are cleaner technologies being
    introduced and how efficiently are vehicles being
    used?
  • Are environmental management and monitoring tools
    being used effectively to support policy-making?
