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 Simulation Modelling of Rural Roads and Driver Assistance Systems
Sammanfattning : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. LÄS MER
3. Trafikslag på undantag : Cykeltrafiken i Stockholm 1930-1980
Sammanfattning : The modal share of bicycle traffic in Stockholm increased from 20 per cent to over 30 per cent during the 1930s, and reached staggering levels during World War Two – peaking at over 70 per cent. Soon after the war, however, the share declined rapidly. LÄS MER
4. 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
5. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems
Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.
