2. 1. Improved road design for future maintenance : analysis of road barrier repair costs

   Author : Hawzheen Karim; Ulf Isacsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Building engineering; Byggnadsteknik; Vägprojektering för minskade drift- och underhållskostnader;

   Abstract : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. READ MORE

4. 2. Safety margins in the driver

   Author : Rickard Nilsson; David Lee; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; Psykologi; Psychology; psykologi;

   Abstract : The primary aim of this thesis is to highlight the most important features of driving and to describe the models that have attempted to conceptualise these features. The discussion focuses on the concept of "safety margin." The concept is elaborated upon in an effort to enhance its usefulness as an empirical tool in traffic research. READ MORE

5. 3. A Simulation-Based Safety Analysis of CACC-Enabled Highway Platooning

   Author : Maytheewat Aramrattana; Tony Larsson; Cristofer Englund; Jonas Jansson; Vicente Milanés; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; driving simulator; traffic simulator; network simulator; C-ITS; cooperative intelligent transport systems; platooning;

   Abstract : Cooperative Intelligent Transport Systems (C-ITS) enable actors in the transport systems to interact and collaborate by exchanging information via wireless communication networks. There are several challenges to overcome before they can be implemented and deployed on public roads. READ MORE

6. 4. Pre-Crash and In-Crash Car Occupant Safety Assessment

   Author : Alexandros Leledakis; Chalmers tekniska högskola; []

   Abstract : Tens of millions are annually injured in Road Traffic Accidents (RTAs) worldwide, while the estimated number of RTA fatalities amounted to 1.35 million in 2016. In Europe, car occupants hold the largest share (48%) of fatalities among all road users. The high fatality and injury numbers motivate the work of enhancing road traffic safety. READ MORE

7. 5. Predictable and Scalable Medium Access Control for Vehicular Ad Hoc Networks

   Author : Katrin Sjöberg Bilstrup; Erik G. Ström; Elisabeth Uhlemann; Maria Kihl; Högskolan i Halmstad; []
