  1. Environmental impact of individual transport Collective of Environmental Section Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  2. Negative influences of traffic • Emissions • Producing traffic means • Construction and operation of roads • Colours and paint coat of traffic signs • Chemical de-icing materials • Abrasion of tyres and surface of road • Fragmentation of landscape • Storage and transport of fuels • Transport of dangerous substances • Land use Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  3. Negative influences of traffic on different levels • Global (contribution to greenhouse effect) • Regional (damage of vegetation, acid and nitrogen deposition) • Local (direct pollution, noise, pollution of soil and water, barrier effect) Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  4. Traffic emissions • Exhaust gasses contain many chemical substances in different concentrations with effect on human health • Toxic, genotoxic and muttagenic effects • Mass unit of air pollutants from road traffic is 10 times higher in cities and big agglomerations in comparison with air pollutants from the other sources (industry) Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  5. Contamination of the air by emissions Pollutants • With limits: NOx, CO, SO2, PM • Without limits: CO2, N2O, CH4 • Others: PAHs, PCDDs, PCDFs, PGE(Pt, Pd, Rh), phenols, ketone, tar, benzene, toluene, xylene, 1,3- butadiene Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  6. Negative effects of selected pollutants • Greenhouse effect (CO, CO2, CH4, N2O) • Respiratory disease (NOx, SO2) • Toxicity (benzene) • Muttagenity, carcinogenity (PAHs, n-PAHs, aldehyde) Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  7. CO2 emissions -trends and prognosis • Increase depends on consuming of petrol and diesel oil • Decrease until 2015 is not real Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  8. CO emissions - trends and prognosis • Decrease – influece of catalyzers Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  9. NOx emissions – trends and prognosis • Increasing by spark ignition engine only (closed-loope catalyzer) Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  10. NM VOCs emissions – trends and prognosis • There are influence of catalyzers • New cars perform the rules of EURO Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  11. PM emissions - trends and prognosis • The diesel emissions of PM are limited • The trends are variable because the consumption of diesel oil increase Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  12. SO2 emissions - trends and prognosis • Depends on sulphur contain in fuels • The change in the graph reflects adoption of low-sulphur fuels Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  13. PAHs emissions - trends and prognosis • There are not significant different between old and new cars Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  14. Trends and prognosis of emissions • Limited emissions decrease excepting particular matters, which have variable trend • The main problem - greenhouse gasses and POPs: In these cases, measures (catalytic converters, promotion of public transport, emission limits EURO, etc.) do not manage the rapid increase of transport performance especially in road traffic Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  15. Traffic influences on human health • Direct • Noise, air pollution, accidents, annoyance • Non-direct • Restriction of active transport means • Restriction of spontaneous motional activities • Epidemiological risk of international mobility • Restriction of social contacts Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  16. Influences of noise on human health • Acute effects: stress-defence • Increase of blood pressure • Accelerated pulse • Contraction of blood-vessels • Increase of the adrenalin level • Loss of magnesium • Effect on psychics – tiredness, depression, annoyance, agressivity, unwillingness • Decrease of performance, memory, attention Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  17. Influences of noise on human health • Chronic effects: civilization desease • Fixing acute effects • Origin of hypertension • Damage of blood-vessels • Decrease of immune ability • Feeling tiredness • Existence of civilization disease is direct rule of noise Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  18. Physical inactivity • Significant health problem • Estimation: • - Takes part in 1.9 million of deads and 19 millions DALYs (disability adjusted life years) • - Takes part in 10-16 % of events of breast and bowel carcinoma, diabetes and in 22% of ischaemic heart disease • - Share of deaths, where physical inactivity takes part is about 5-10 % with important subregional differences; that is around 600.000 a year, what is approximately 5 times more than due to traffic accidents Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  19. Situation in European cities • More than 50% of car journeys is shorter than 5 km that´s 15 minutes by bicycle • More than 30% of car journeys is shorter than 3 km that´s 20 minutes of walk • During one day, an average European living in a city: - Rides a bicycle for 0,5 km - Walks 1 km - Travels by car a distance of 27,5 km Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  20. Factors that influences the choice of traffic • Availability • Speed • Comfort • Pertinence Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  21. Factor that influences the choice of traffic • Real and perceive danger of a traffic accident (where is safety, where could I let go children) • Environment of roads affect negatively and dangerously, cyclists and pedestrians are at a bump in the higher danger of healthy effects over against users of cars • Danger bump of pedestrian and cyclist with car is indirect rule of proportion in quantity of pedestrians and the cyclists, which are on a road Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  22. Influencing needs of transport by the land planning • Responsibility of the municipality for the behaviour of the citizen in transport - The way of the organization of activities in the area - transport distances - Suburbanization - Commercial zones in the vicinity of cities Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  23. The possibilities decreassing of negative effect • Restriction of increase of total volume of transportation • Changing of modal split to rail transport • Including external cost to total cost of traffic • Adoption of stricter norms for exhaust and noise emissions • Using of alternative fuels • Restriction of traffic operation in resident agglomerations Brno, Czech Republic, 24 June 2005 COST 355 – WG2

  24. THE PEP • Transport, health and environment pan-european programme • Accepted by „High-level meeting on transport environment and health (Geneva, 5 July 2002) • Three important area were selected from „UNECE Programme of Joint Action on Transport and the Environment and the WHO Charter on Transport, Environment and Health“: - Connection environmental and health with traffic policy - Travel demand management and changes in traffic - Urban transport Brno, Czech Republic, 24 June 2005 COST 355 – WG2
