1. Performance Measures of Road Infrastructures
Sammanfattning : Roads are transport infrastructures that play a fundamental role in the development of societies and businesses. They are valuable assets, as they connect places, provide mobility, create jobs and stimulate economic prosperity. LÄS MER
2. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions
Sammanfattning : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

3. EstimatingChloride concentration in surface water and groundwater duet to deicing salt application
Sammanfattning : A road in operation along with its traffic can pose aserious pollutant threat to groundwater and surface water inits vicinity. Examples of pollutants are metals from thecorrosion of vehicles, rails and poles and the wear of roadsurfaces and tyres; hydrocarbons from the wear of roadsurfaces, tyres, exhausts, oils; sodium chloride from roadsalt; and hazardous goods discharged in accidents.

4. Road Ecology for Environmental Assessment
Sammanfattning : Transport infrastructure is closely linked to several politically relevant sustainability issues, and since 1985 a formalized environmental assessment process is linked to planning and construction of new roads and railways in the EU (EU directives 85/337/EEC and 2001/42). The aim of the environmental assessment process is to think in advance; to identify, predict and evaluate significant environmental changes resulting from a proposed activity, in order to adjust the proposed activity accordingly and to avoid unnecessary and unexpected consequences.

5. Analytical tools and information-sharing methods supporting road safety organizations
Sammanfattning : A prerequisite for improving road safety are reliable and consistent sources of information about traffic and accidents, which will help assess the prevailing situation and give a good indication of their severity. In many countries there is under-reporting of road accidents, deaths and injuries, no collection of data at all, or low quality of information. LÄS MER
