1. Road traffic metals : sources and emissions
Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER
2. Traffic Emissions of Aerosols
Sammanfattning : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. LÄS MER
3. Health costs of particle emissions : economic valuation of increased mortality due to exhaust emissions of fine particles
Sammanfattning : .... LÄS MER
4. Nanoparticles from shipping and road traffic
Sammanfattning : In the urban environment road traffic is the dominant source of aerosol particles while in coastal and harbour areas shipping is also a significant source. For shipping there are no direct regulations regarding particle emissions. LÄS MER
5. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation
Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER
