1. 1. 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

3. 2. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems

   Författare :Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; urban roads; posted speed limits; road characteristics; free-flow speed; time headway; vehicle-bicycle interactions; logit model; yielding probability; cooperative systems and warning messages.; Transportvetenskap; Transport Science;

   Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

4. 3. Traffic Simulation Modelling of Rural Roads and Driver Assistance Systems

   Författare :Andreas Tapani; Jan Lundgren; Haris N. Koutsopoulos; Linköpings universitet; []
   Nyckelord :Traffic; Micro; Simulation; Model; Car following; Rural road; Driver; Fatigue; Rumble strip; Adaptive cruise control; Active safety system; Safety; Evaluation; Overtaking; Traffic lane; Mathematical model; Thesis; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

   Sammanfattning : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. LÄS MER

5. 4. Creating Safety in Air Traffic Control

   Författare :Johan M. Sanne; Boel Berner; Jane Summerton; Dave Randall; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Risk; safety; air traffic control; ethnography; schemes; rules; resources; cognitive; social; interaction; coordination; socio-technical systems; Social anthropology ethnography; Socialantrolopologi etnografi;

   Sammanfattning : Is flying safe? Indeed it is -- statistics tell us that it is far more dangerous to drive a car or take the train. But flight safety does not just happen. Instead, as it is argued in this book, it is created by a well-developed air traffic control system that continues to be highly effective -- despite increasing volumes of traffic. LÄS MER

7. 5. Safety at Rail-Road Level Crossings

   Författare :Mohammad Shahriari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver behaviour; risk analysis; traffic safety; rail road crossings; safety;

   Sammanfattning : Safety related to traffic at rail/road level crossings has long been a major issue for rail operators all over the world. Eliminating these level crossings entirely would be a desirable solution. However converting them into separate types is very expensive and not reasonable in many cases, e.g. LÄS MER
