  1. 1. Automating condition monitoring of vegetation on railway trackbeds and embankments

    Författare :Roger G. Nyberg; Narendra K. Gupta; Mark S. Dougherty; Siril Yella; David J. Murray-Smith; Alistair Armitage; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Vegetation growing on railway trackbeds and embankments present potential problems. The presence of vegetation threatens the safety of personnel inspecting the railway infrastructure. In addition vegetation growth clogs the ballast and results in inadequate track drainage which in turn could lead to the collapse of the railway embankment. LÄS MER

  3. 2. 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

  4. 3. Developing decision support systems for last mile transportation problems

    Författare :Vijay Paidi; Johan Håkansson; Hasan Fleyeh; Roger G. Nyberg; Vitaly Komashilov; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; parking spaces; attended handovers; user satisfaction; pollution; business opportunities; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Last mile transportation is the most problematic phase of transportation needing additional research and effort. Longer waits or search times, lack of navigational directions and real-time information are some of the common problems associated with last mile transportation. LÄS MER

  5. 4. Parking support model for open parking lots

    Författare :Vijay Paidi; Johan Håkansson; Roger G. Nyberg; Hasan Fleyeh; Seifedine Kadry; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; parking; deep learning; pollution; cruising; detection; tracking; forecasting;

    Sammanfattning : Parking is a common process performed by vehicle drivers when they arrive at their destination. It is considered to be the last mile transportation problem of personal vehicles. Some of the common problems observed by drivers are additional cruising, congestion, pollution, and driver frustration. LÄS MER

  7. 5. Objective Assessment of Loose Gravel Condition using Machine Learning with Audio-visual Observation

    Författare :Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Niklas Lavesson; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road condition assessment; Loose gravel; Sound analysis; Machine learning; Image analysis; Audio analysis; Image and audio data fusion;

    Sammanfattning : A well-maintained road network is essential for sustainable economic development, providing vital transportation routes for goods and services while connecting communities. Sweden's public road network includes a significant portion of gravel roads, particularly cost-effective for less populated areas with lower traffic volumes. LÄS MER
