1. 11. Visuospatial inattention and processing speed : Predictors of long-term outcome and patterns of change after ischemic stroke

   Sammanfattning : Impairments of visuospatial attention, language, and processing speed (PS) are common early after stroke and have been associated with unfavorable short-term functional outcomes but little is known about this relationship in the long-term. This thesis investigates 1) the potential importance of visuospatial inattention (VSI) and language impairments (LI) as predictors of functional outcomes 7 years after an ischemic stroke (studies I-II) and 2) presence of lateralized inattention 7 years after stroke and potential predictors of this phenomenon (study III).

   Sammanfattning : Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. LÄS MER

4. 13. In-vehicle speed adaptation - On the effectiveness of a voluntary system

   Författare :Magnus Hjälmdahl; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Vägtransportteknik; Traffic safety; In-car observations; Long-term effects; Speed; Driver behaviour; ISA; Active Accelerator Pedal;

   Sammanfattning : The overarching aim of this thesis is to study the long term effects of a voluntary speed adaptation system, the Active Accelerator Pedal (AAP), and its effectiveness for different driver types. The papers making up this thesis are based on a study carried out on 284 vehicles and drivers in the Swedish city of Lund from 1999 until 2002. LÄS MER

5. 14. Speed characteristics of urban streets based on driver behaviour studies and simulation

   Författare :Karin F. M. Aronsson; Karl-Lennart Bång; Bengt Holmberg; KTH; []
   Nyckelord :Speed; Characteristics; Urban area; Road network; Street; Traffic; Driver; Side-friction element; Driving simulator; Simulation; Measurement; Behaviour; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The objective of the study was to gain in-depth knowledge of speed relationships for urban streets. The speed characteristics were examined using a number of methods for data collection. LÄS MER

7. 15. Bilars hastighet längs gator med gupp: metod för framställning av hastighetsprofiler och analys av hastighetsförlopp

   Författare :Joachim Karlgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road hump; speed reducing effect; traffic calming; speed measurement; speed profile;

   Sammanfattning : There is a well-documented relationship between motorists speed and the number, respectively severity, of accidents in urban streets. Also, studies have shown that vehicle emissions can increase on streets where speed reducing measures are installed, if the driving pattern of the motorists becomes more jerky. LÄS MER
