  3. 2. Waiting for the Magic Bus: Unravelling the Impact of Bus Design on Station Dwell Time : A Comprehensive Analysis and Case Study

    University essay from KTH/Transportplanering

    Author : Efrat Aviad; [2023]
    Keywords : ;

    Abstract : With the continuous decrease in average speed in cities, public transport operators need to think of new ways to improve operation efficiency and shorten total trip durations. This thesis investigates how bus design aspects, like door configuration and engine type, can affect the station dwell time, in this case, service time per passenger. READ MORE

  4. 3. Identifying Piggybacking with Radar and Neural Networks

    University essay from Lunds universitet/Matematik LTH

    Author : Joel Sigurdsson; Hannes Olsson; [2022]
    Keywords : neural networks; classification; radar; access control; artificial; recurrent; convolutional; point clouds; cnn; ann; lstm; rnn; optimization; gradient descent; camera; piggybacking; tailgating; fmcw; pointnet; Mathematics and Statistics;

    Abstract : A common problem in access control is piggybacking. This is when a person without authorized access sneaks closely behind another with access through a door. This thesis seeks to answer whether using radar is a viable solution when attempting to detect piggybacking. READ MORE

  5. 4. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience

    University essay from KTH/Transportplanering

    Author : Yari de Graaf; [2021]
    Keywords : ;

    Abstract : Timetable development and design is a complex process that is crucial for safe and efficient railway operations. The combination of steel wheels and steel rails makes it possible to create trains and to transport many vehicles, thus passengers and freight, at the same time, but it also results in longer braking distances.
