1. 11. Consequences of Traffic Casualties in Relation to Traffic-Engineering Factors - An Analysis in Short-term and Long-term Perspectives

   Författare :Monica Berntman; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Police and Hospital Data; Traffic Casualties; Consequences for Society and Individulas; in Short-term and Long-term Perspectives; Health Index; Traffic-Engineering Factors; ISS; Potential Traffic Safety Measures; Predictors; Road transport technology; Vägtransportteknik;

   Sammanfattning : The over-arching objectives of this thesis were to formulate a method to describe the consequences of traffic casualties, and to explain the influence of different traffic engineering factors on these consequences for society and individuals over time. A more detailed objective was to examine whether available short-term indicators can be used to predict consequences in a long-term perspective. LÄS MER

3. 12. Towards an efficient use of infrastructure and the built environment : Essays in transport and housing economics

   Författare :Lina Jonsson; Fastighetsvetenskap; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hedonic pricing; Noise; Railway traffic; Road traffic; Congestion pricing; Acceptability; Road user charging; Political Economy; Railway; Marginal cost; Accident probability; Level crossings; Housing Economics; Property tax;

   Sammanfattning : All four papers in the thesis share a common theme: how to achieve an efficient use of infrastructure and the built environment. In the presence of externalities, pricing according to the (short-run) marginal cost is one answer on how this can be achieved and the first two papers estimates parts of the marginal cost of traffic.

4. 13. Development of traffic conflicts technique for different environments: A comparative study of pedestrian conflicts in Sweden and Jordan

   Författare :Lina Shbeeb; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perception of conflicts.; non-signalised junctions; signalised junctions; accident prediction; accident to conflict conversion factors; TA-speed graphs; conflict speed; time to accidents; conflict sub-grouping; severity index; threshold; relevant road-user; pedestrian conflict; Traffic safety; traffic conflict technique; Technological sciences; Teknik; Social sciences; Samhällsvetenskaper;

   Sammanfattning : This study is aimed at improving the current Swedish Traffic conflicts Technique [TCT] in relation to vehicle-pedestrian conflicts. The present definition of conflict severity appears to produce less severe conflicts than they might be, particularly if the relevant road user (RRU) is the pedestrian. LÄS MER

5. 14. 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. 15. 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
