  1. 11. Short term traffic speed prediction on a large road network

    University essay from KTH/Matematisk statistik

    Author : Titing Cui; [2019]
    Keywords : ;

    Abstract : Traffic flow speed prediction has been an important element in the application of intelligent transportation system (ITS). The timely and accurate traffic flow speed prediction can be utilized to support the control, management, and improvement of traffic conditions. READ MORE

  3. 12. Machine Learning Approaches on a Travel Time Prediction Problem

    University essay from KTH/Optimeringslära och systemteori

    Author : Sara Danielsson; [2018]
    Keywords : ;

    Abstract : This thesis concerns the prediction of travel times between two points on a map, based on a combination of link-scale road network data and historical trip-scale data. The main idea is that the predictions using the road network data can be improved by a correction factor estimated from historical trip data. READ MORE

  4. 13. The road to food security : evaluating and improving open-access road data in Tanzania with satellite imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Corey Nicholas Ragosnig; [2018]
    Keywords : Physical Geography and Ecosystem Analysis; Human Geography; Remote Sensing; Road Extraction; Food Security; Open-Access Data; Earth and Environmental Sciences;

    Abstract : Metoderna som används för att göra den globala livsmedelsförsörjningen tryggare har bytt fokus från själva produktionen av jordbruksgrödor till att öka människors tillgänglighet till marknader. Analyser visar att det finns ett samband mellan inkomst, avlägsenhet, och hur stor andel av god jordbruksmark faktiskt används för jordbruk. READ MORE

  5. 14. Deep Learning Models for Route Planning in Road Networks

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

    Author : Tianyu Zhou; [2018]
    Keywords : Route Planning; Pathfinding; Shortest Path Algorithms; Road Networks; Deep Learning; Neural Networks.; Ruttplanering; Sökning; Algoritmer för att finna kortaste väg; Vägnät; Djupinlärning; Neuronnätverk.;

    Abstract : Traditional shortest path algorithms can efficiently find the optimal paths in graphs using simple heuristics. However, formulating a simple heuristic is challenging under the road network setting since there are multiple factors to consider, such as road segment length, edge centrality, and speed limit.

  6. 15. Road traffic congestion detection and tracking with Spark Streaming analytics

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

    Author : Thorsteinn Thorri Sigurdsson; [2018]
    Keywords : streaming; graph processing; congestion; community detection; connected components;

    Abstract : Road traffic congestion causes several problems. For instance, slow moving traffic in congested regions poses a safety hazard to vehicles approaching the congested region and increased commuting times lead to higher transportation costs and increased pollution. READ MORE
