  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.

  3. 2. Train crashes : consequences for passengers

    Författare :Rebecca Forsberg; Ulf Björnstig; Britt-Inger Saveman; Inggard Lereim; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accident; crash; disaster; experiences; injuries; injury inducing objects; media coverage; railway; safety;

    Sammanfattning : Background: Globally, and in Sweden, passenger railway transport is steadily increasing. Sweden has been relatively free from severe train crashes in the last decades, but the railway infrastructure is alarmingly worn and overburdened, which may be one reason for an increasing number of reported mishaps.

  4. 3. Dwell time delays for commuter trains : An analysis of the influence of passengers on dwell time delays

    Författare :Ruben Kuipers; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dwell time; Passengers; Delays; Trains; Railway; Station; Automatic passenger count data;

    Sammanfattning : The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. LÄS MER

  5. 4. Timetable Analysis based on Social Cost and Simulation

    Författare :Jennifer Warg; Markus Bohlin; Oskar Fröidh; Carl-William Palmqvist; Paola Pellegrini; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway capacity allocation; timetable analysis; social costs; microscopic railway simulation; macroscopic railway simulation; passengers; timetable performance; early departing freight trains; Järnvägskapacitet; tidtabellsanalys; sociala kostnader; mikroskopisk järnvägssimulering; makroskopisk järnvägssimulering; resande; tidtabellseffektivitet; tidiga godståg; Transportsystem; Transport Systems;

    Sammanfattning : The timetable is essential for railway traffic. Its design affects rail operations – and by extension all operators, passengers, and freight clients. International practice for capacity allocation varies and there is no common algorithm for designing and evaluating timetable changes. LÄS MER

  7. 5. Difficulties to Read and Write Under Lateral Vibration Exposure : Contextual Studies Of Train Passengers Ride Comfort

    Författare :Jerker Sundström; Shafiquzzaman Khan; Neil J. Mansfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lateral vibrations; passenger activities; reading; writing; sitting posture; frequency weighting; rated difficulty; field study; laboratory study; transient vibrations; stationary vibrations.; Vehicle engineering; Farkostteknik;

    Sammanfattning : Many people use the train both as a daily means of transport as well as a working place to carry out activities such as reading or writing. There are, however, several important factors in this environment that will hamper good performance of such activities. LÄS MER
