1. 1. Young Drivers and Their Passengers : Crash Risk and Group Processes

   Författare :Inger Engström; Kjell Granström; Nils Petter Gregersen; Håkan Alm; Linköpings universitet; []
   Nyckelord :Young drivers; passengers; crash risk; group processes; Unga förare; passagerare; olycksrisk; grupprocesser; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Sammanfattning : The overall aim was to elucidate the effects of vehicle passengers on young drivers. This generated two specific aims and four papers. The first aim was to investigate the crash risk for young drivers with passengers and to establish whether such accidents involve any special circumstances compared to those that occur without passengers.

   Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER

4. 3. Simulation and Evaluation of Urban Rail On-board Crowding

   Författare :Soumela Peftitsi; Erik Jenelius; Oded Cats; Andreas Tapani; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

   Sammanfattning : As travel demand grows in many metropolitan areas, overcrowding in public transport systems has become a major issue. Crowding distribution can be highly uneven over station platforms and multi-car transit vehicles. This implies that cars are not equally utilized and thus, passengers perceive on-board crowding higher. LÄS MER

5. 4. Transition Towards Fixed-Line Autonomous Bus Transportation Systems

   Författare :Jonas Hatzenbühler; Erik Jenelius; Oded Cats; Clas Rydergren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Buses; Public Transportation; Network Design; Resource Allocation; Simulation-based multi-objective Optimization; Transportvetenskap; Transport Science;

   Sammanfattning : In the last years the steady development of autonomous driving technology has enabled the deployment of more mature autonomous vehicles. These vehicles have been applied in several pilot projects worldwide, most commonly in the form of small buses. LÄS MER

7. 5. Aspects of improving punctuality : from data to decision in railway maintenance

   Författare :Birre Nyström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : The increasing demand for transportation and sustainability makes railways attractive. The ongoing deregulation of state-owned railways means that many new organisations are entering the railway sector. LÄS MER
