    Författare :Sven-Olof Lundkvist; KTH; []
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  3. 2. Older car drivers - Needs of vehicle support for safe individual mobility

    Författare :Thomas K Broberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elderly driver; Collision avoidance; Older driver; On-road assessment; ADAS; Driver attitudes; Active Safety; Driver assist; Driver behaviour;

    Sammanfattning : As the demographic is changing with the growth of the population of older citizens, concerns have been raised for this group in terms of mobility as well as traffic safety. In this context the automobile is an important means of transport. LÄS MER

  4. 3. Predictive model of perceived driving stability at high speeds under aerodynamic excitations

    Författare :Arun Kumar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver-vehicle interaction; unsteady aerodynamics; Driving simulator; on-road tests; predictive model; vehicle stability; subjective evaluation;

    Sammanfattning : The automotive industry is continuously advancing towards more energy-efficient vehicle designs.  Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when  exposed to external excitations such as unsteady aerodynamic forces created by the flow of air  around them.

  5. 4. Driving assessment and driving behaviour

    Författare :Helena Selander; Torbjörn Falkmer; Jönköping University; []
    Nyckelord :;

    Sammanfattning : IntroductionDriving is an important part of everyday life and represents independence. Activities, both productive and social, may be affected if a person can no longer drive. Older drivers, as a group, have a low crash rate. LÄS MER

  7. 5. Automated Gravel Road Condition Assessment : A Case Study of Assessing Loose Gravel using Audio Data

    Författare :Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Diala Jomaa; Mirka Kans; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Gravel roads; road maintenance; convolutional neural network CNN ; SVM; decision trees; ensemble bagged trees; GoogLeNet; ResNet50; ResNet18; sound analysis;

    Sammanfattning : Gravel roads connect sparse populations and provide highways for agriculture and the transport of forest goods. Gravel roads are an economical choice where traffic volume is low. In Sweden, 21% of all public roads are state-owned gravel roads, covering over 20,200 km. LÄS MER
