1. 11. Konkurrens, anbudsvärdering och entreprenörernas innovativa agerande inom vägbyggnadssektorn

   Författare :Anna Seeger Meriaux; Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vägtransportteknik; Road transport technology; innovative actions; road construction; competition; tender evaluation; Construction technology; Anläggningsteknik; Transportteknik; Transport technology;

   Sammanfattning : The Swedish National Road Administration SNRA is responsible for the long term de-velopment of the road transport system, and spends large sums on road construction and 'operation and maintenance'. Improvements in efficiency which are small in per-centage terms therefore yield relatively large monetary effects. LÄS MER

3. 12. Utvärdering av cykelfälts effekter på cyklisters säkerhet och cykelns konkurrenskraft mot bil

   Författare :Annika Nilsson; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mode choice; route choice; bicycle flow; bicycle counts; level of service; attitudes; speed; lateral position; Road transport technology; behavior; Vägtransportteknik; Bicycle traffic; traffic safety; bicycle planning; bicycle lanes;

   Sammanfattning : This work presents an evaluation of bicycle lane effects on cyclist safety and the ability of bicycles to compete with car traffic. Thirteen Swedish urban streets were studied before and after bicycle lanes were introduced. LÄS MER

4. 13. Valuing Reductions in the Risk of Traffic Accidents Based on Empirical Studies in Sweden

   Författare :Ulf Persson; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Säkerhetsteknik; Safety technology; Vägtransportteknik; Road transport technology; Road Traffic; Risk Reduction; Value of Life; Cost of Accidents; Stated Preference; Contingent Valuation;

   Sammanfattning : At the beginning of the 1990s the Swedish National Road Administration (SNRA) adopted the willingness to pay (WTP) approach for estimating the benefits of safety improvements. However, since then there have been discussions about how to find the most valid and reliable empirical methods to conduct WTP studies. LÄS MER

5. 14. Passenger assessments of quality in local public transport- measurement, variability and planning implications

   Författare :Helena Sjöstrand; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passenger; public transport; quality; survey; Stated Preference; assessment; assignment; planning; Transportteknik; Transport technology; Road transport technology; Vägtransportteknik;

   Sammanfattning : The aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. LÄS MER

7. 15. On the Relations between Driving Patterns, Exhaust Emissions and Network Characteristics in Urban Driving

   Författare :Lena Smidfelt-Rosqvist; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic calming; intersections; driving adaptation; speed limits; Road transport technology; driving behaviour; Vägtransportteknik; overall effects; trip-long; non-local effects;

   Sammanfattning : The planning and design of street networks in cities influence driving behaviour and give rise to variations in driving patterns (i.e., speed and acceleration profiles) that affect exhaust emissions and fuel consumption. LÄS MER
