   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

   Sammanfattning : Swedish towns have been developed according to the planning guidelines issued by the National Road Administration and the National Board of Urban Planning in 1968; SCAFT 1968 Riktlinjer för stadsplanering med hänsyn till trafiksäkerhet (The SCAFT Guidelines 1968 Principles for urban planning with respect to road safety). The five principles for urban planning suggested are; Locating activities and functions, Separating different classes of traffic, Differentiation within each road network, Clearness, simplicity and uniformity as well as Neighbourhood units.

5. 9. Accidents between pedestrians, bicyclists and motorized vehicles: Accident risk and injury severity

   Författare :Höskuldur Kröyer; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accidents; pedestrians; bicyclists; exposure; risk; consequence; speed; age.;

   Sammanfattning : The aims of this work are to better understand (1) the relation between exposure and the risk of an accident between pedestrians and motorized vehicles and between bicyclists and motorized vehicles occurring at urban intersections and (2) how the speed environment and the victim´s age relate to the injury severity/outcome once a pedestrian or a bicyclist has been struck by a motorized vehicle. Cross sectional studies are used, and the relations are analyzed using multinomial logit models, negative binomial regression and other statistical methods. LÄS MER
