Transportation environment
- 2. WHAT IS TRANSPORTATION? • Transportation is a means to carry our goods from a place to other. In urban areas automobiles form a significant source of a number of air pollutants, namely, particulates, NOx, hydrocarbons, carbon monoxide and lead. These pollutants are produced when fuel is burnt under less than ideal conditions. • Non-uniform oxygen supply within the combustion chamber and lower flame temperature leads to incomplete combustion releasing CO, HC and un-burnt particles in the exhaust.
- 4. TRANSPORT MARKET OUTCOMES Economic Outcomes Environmental Outcomes Social Outcomes • Accessibility • Transport operation cost • Productivity • Efficiency • Costs to Economy • Benefits to Economy • Resource use • Emissions to air • Emissions to soil and water • Noise • Waste • Accessibility and affordability • Safety and security • Fitness & health • Equity • Working
- 5. NEGATIVE INFLUENCE OF TRAFFIC GLOBAL Contribution to the Green house effect. REGIONAL Damage of vegetation, acid and nitrogen deposition. LOCAL Direct pollution, noise, pollution of soil and water.
- 6. NEGATIVE INFLUENCE OF TRAFFIC • Transportation infrastructural requirements like parking places, roadways, airports etc. need space for which we cut trees on a large scale, shrink our agricultural fields or even cover our water bodies. • Air-conditioning systems constitute CFCs caused ozone layer depletion. • Habitat fragmentation is also responsible for endangering our bio-resources. • Transportation of hazardous substances increases a risk of spillage. • Transport allows urban expansion which consumes valuable agricultural lands. Noise and vibrations cause mental disability, irritation and lack of concentration. Transport can increase bio-security risks. • Transportation produces solid wastes in bulk through the maintenance of old parts or when vehicles become old. Besides, regular change of oil etc. also leads to water and soil pollution • Energy crisis as energy is the most worrisome resource.
- 7. TRAFFIC EMISSION • 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).
- 8. CONTAMINATION OF THE AIR BY EMISSIONS NOx Damage to respiratory tracts. CO Reduces oxygen uptake in blood. Noise Pollution Irritability, nervousness, damage to hearing, disturbed sleep, high blood pressure.
- 9. TRAFFIC INFLUENCES ON HUMAN HEALTH DIRECT INDIRECT Noise Restriction of active transport means Air pollution Restriction of spontaneous motional activities Accidents Restriction of social contacts
