1. 6. On Men and Cars : An Ethnographic Study of Gendered, Risky and Dangerous Relations

   Författare :Dag Balkmar; Jeff Hearn; Cecilia Åsberg; Victoria Robinson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gender; masculinity; technology; cars; risk; danger; emotions; car modification; Genus; maskulinitet; teknik; bilar; risk; fara; emotioner; bilstyling; Gender Studies; Genusvetenskap;

   Sammanfattning : It is well known that young men constitute a high-risk group in terms of accidents involving both themselves and others. But comparatively little is known about the roles of gender, masculinity and automobility in reproducing or subverting such particularly risky performances of identity. LÄS MER

3. 7. Road surface characterization using near infrared spectroscopy

   Författare :Johan Casselgren; Matti Kutila; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spektroskopi; Väglagsklassificering; Friktion; Väglagskarakterisering; Experimental Mechanics; Experimentell mekanik;

   Sammanfattning : This thesis presents a technology and method for classifying and characterizing different road conditions such as dry asphalt and asphalt covered with water, ice and snow. The method uses light sources of different wavelengths to illuminate the road surface and a detector to measure the reflected light from the road surfaces, dependent on how the surface have absorbed, scattered and polarized the light it is possible to classify the road condition.

4. 8. Towards an efficient use of infrastructure and the built environment : Essays in transport and housing economics

   Författare :Lina Jonsson; Fastighetsvetenskap; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hedonic pricing; Noise; Railway traffic; Road traffic; Congestion pricing; Acceptability; Road user charging; Political Economy; Railway; Marginal cost; Accident probability; Level crossings; Housing Economics; Property tax;

   Sammanfattning : All four papers in the thesis share a common theme: how to achieve an efficient use of infrastructure and the built environment. In the presence of externalities, pricing according to the (short-run) marginal cost is one answer on how this can be achieved and the first two papers estimates parts of the marginal cost of traffic.

5. 9. Cycle paths’ degradation processes and surface condition assessment

   Författare :Martin Larsson; Sigurdur Erlingsson; Anna Niska; Inge Hoff; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction design; cycle paths; degradation; distress modes; maintenance; municipalities; survey; cycling comfort; road surface measurements; surface evenness; surface texture; Building Materials; Byggnadsmaterial;

   Sammanfattning : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. LÄS MER

7. 10. A Sound Approach Toward a Mobility Aid for Blind and Low-Vision Individuals

   Sammanfattning : Reduced independent mobility of blind and low-vision individuals (BLVIs) cause considerable societal cost, burden on relatives, and reduced quality of life for the individuals, including increased anxiety, depression symptoms, need of assistance, risk of falls, and mortality. Despite the numerous electronic travel aids proposed since at least the 1940’s, along with ever-advancing technology, the mobility issues persist. LÄS MER
