1. 1. Monitoring winter road friction using floating car data

   Författare :Sofia Sollén; Johan Casselgren; Mikael Sjödahl; Hawzheen Karim; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Floating Car Data; Winter Road Maintenance; Tire-to-Road Friction; Road Safety; Vision Zero; Intelligent Transport Systems; Experimental Mechanics; Experimentell mekanik;

   Sammanfattning : More than a million people die every year due to road traffic accidents globally where one in five serious or fatal accidents occurs during severe weather conditions. Sweden is in the lead of Vision Zero, with the aim of zero casualties due to road traffic, and every year new countries and organisations accept the challenge of saving lives. LÄS MER

3. 2. Evaluation of Road Equipment with Emphasis on Condition Assessment

   Författare :Sven-Olof Lundkvist; Ulf Isacsson; Rolf Magnusson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road equipment; Condition assessment; State-of-the-art; Mobile measurement; Road marking; Road sign; Post delineator; Traffic light; Street lighting; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : This doctoral thesis deals primarily with condition assessment of road equipment. The road equipment concept is defined by five main groups, road lighting, fences and barriers, vertical signs, horizontal signs and traffic signals, respectively. LÄS MER

4. 3. Safety Evaluation of Road Characteristics

   Författare :Sarbaz Najib Othman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident data; FOT data; Overtaking maneuvers; Road safety; PC-Crash; Critical road parameters; Horizontal curves;

   Sammanfattning : Accidents are rare and widely distributed on the road network, which poses a challenge for road safety improvement. Traditional methods alone, such as accident analyses and experimental studies, do not explain all accident causation factors. LÄS MER

5. 4. Distributed Road Grade Estimation for Heavy Duty Vehicles

   Författare :Per Sahlholm; Karl Henrik Johansson; Emilio Frazzoli; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; estimation; distributed systems; automatic control; heavy duty vehicles; road grade; road maps; Automatic control; Reglerteknik;

   Sammanfattning : An increasing need for goods and passenger transportation drives continued worldwide growth in traffic. As traffic increases environmental concerns, traffic safety, and cost efficiency become ever more important. Advancements in microelectronics open the possibility to address these issues through new advanced driver assistance systems. LÄS MER

7. 5. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies

   Författare :Anna Markiewicz; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic pollutants; nanoparticles; stormwater; sorption filters; road dust; emulsions; washwater; vehicle wash; road runoff; microparticles; sweepsand; colloids; street sweeping;

   Sammanfattning : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. LÄS MER
