1. 1. 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

3. 2. 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

4. 3. Forecasting Indian Road Traffic Casualties: Guidance to Prioritize Road Safety Technologies and Regulations

   Författare :Pradeep Puthan Pisharam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effectiveness; safety benefit; Accidents; future crashes; vision zero; assessment; evaluation; crash; ADAS;

   Sammanfattning : India accounts for 11% (nearly 150,000) of global road traffic deaths and its fatality rate is 22.6 per 100,000 people, almost three times higher than that of the European region. India is committed to reducing fatalities and has signed the Stockholm declaration to halve the fatalities by 2030. LÄS MER

5. 4. 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

7. 5. A method for analysing the traffic process in a safety perspective

   Författare :Åse Svensson; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intermediate method; Accidents; pedestrian safety; safety hierarchy; severity; traffic conflicts; interaction; road user behaviour; traffic safety; traffic process; time to accidents; safety indicators; surrogate measures;

   Sammanfattning : The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. LÄS MER
