11. Konkurrens, anbudsvärdering och entreprenörernas innovativa agerande inom vägbyggnadssektorn
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
12. Utvärdering av cykelfälts effekter på cyklisters säkerhet och cykelns konkurrenskraft mot bil
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
13. Valuing Reductions in the Risk of Traffic Accidents Based on Empirical Studies in Sweden
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
14. Passenger assessments of quality in local public transport- measurement, variability and planning implications
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
15. On the Relations between Driving Patterns, Exhaust Emissions and Network Characteristics in Urban Driving
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
