  1. 1. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adam Andersson; [2023]
    Keywords : Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Abstract : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. READ MORE

  3. 2. Construction of a machine learning training pipeline for merging AIS data with external datasources

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Sami Said Yahya; [2022]
    Keywords : AI; Machine Learning; Deep learning; AIS; anomaly detection; RNN; Maritime Traffic;

    Abstract : Machine learning methods are increasingly being used in the maritime domain to predict traffic anomalies and to mitigate risk, for example avoiding collision and groundingaccidents. However, most machine learning systems used for detecting such issues hasbeen trained predominately on single data sources such as vessel positioning data. READ MORE

  4. 3. Deep neural network for object classification and optimization algorithms for 3D positioning in Ultrasonic Sensor Array

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Hui Zhang; [2021]
    Keywords : ultrasonic sensor; simulation; CNN; optimization; localization; object classification;

    Abstract : Ultrasonic sensors are commonly used in automobiles to assist driving maneuvers, e.g., parking, because of their cost-effectiveness and robustness. READ MORE

  5. 4. Artificial Intelligence applications for railway signalling

    University essay from KTH/Transportplanering

    Author : Benjamin Smakic; [2021]
    Keywords : Artificial Intelligence; AI; Machine Learning; ML; Computer Vision; railway signalling; ERTMS level 3; GPS; autonomous train operations; Artificiell Intelligens; Maskininlärning; datorseende; signalteknik; autonoma tåg; självkörande tåg.;

    Abstract : The main purpose of this Master Thesis is to investigate how front-facing, train-mounted cameras and Computer Vision, a type of Artificial Intelligence (AI), can be used to compensate for GPS inaccuracies. By using footage from track-recording cameras, Computer Vision can be utilized to determine the number of tracks and the track occupancy of the train, which would compensate GPS inaccuracies in the lateral positioning.

  6. 5. 1D LIDAR Speed and Motion for the Internet-of-Things : For Railroad Classification Yards

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Edward Chancellor; Kasper Oikarinen; [2021]
    Keywords : LIDAR; Trains; Internet of Things; Motion-tracking; Rail transportation; Railroad classification yards.; LIDAR; Tåg; Sakernas internet; Rörelsespårning; Tågtrafik; Rangerbangårdar.;

    Abstract : This thesis is an investigation into the feasibility of one-dimensional Light Detection and Ranging (LIDAR) sensors for tracking the position and motion of trains on railroad classification yards. Carefully monitoring railway traffic in these areas is important, in order to avoid accidents, optimise logistical operations and hence reduce delays. READ MORE
