  1. 1. Traffic State Estimation on Swedish Highways : Model Comparison using Multisource Data

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

    Author : Jiaqi Xu; [2023]
    Keywords : Traffic State Estimation; Macroscopic Traffic Model; Extended Kalman Filter; Particle Filter; Data Fusion; Trafiklägesuppskattning; Makroskopisk trafikmodell; Utökad Kalman-filter; Partikelfilter; Datafusion;

    Abstract : Due to the escalating demand for traffic information and management, the significance of traffic state estimation, which involves the assessment of traffic conditions on road segments with limited measurement data, is increasing. Two primary estimation methods are model-driven and data-driven. READ MORE

  3. 2. Machine Learning-Based Data-Driven Traffic Flow Estimation from Mobile Data

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

    Author : Pei-Lun Hsu; [2021]
    Keywords : Intelligent transport systems; Traffic flow estimation; Machine learning; Artificial neural network; Mobile data; Intelligenta transportsystem; Estimering av trafikflöde; Maskininlärning; Artificiellt neuronnät; Mobila data;

    Abstract : Comprehensive information on traffic flow is essential for vehicular emission monitoring and traffic control. However, such information is not observable everywhere and anytime on the road because of high installation costs and malfunctions of stationary sensors. READ MORE

  4. 3. Daily pattern recognition of dynamic origin-destination matrices using clustering and kernel principal component analysis

    University essay from KTH/Transportplanering

    Author : Zhiwu Dong; [2021]
    Keywords : origin-destination; pattern recognition; principal component analysis; kernel principal component analysis; k-means cluster; ursprung-destination; mönsterigenkänning; huvudkomponentanalys; analys av kärnhuvudkomponent; k-medelkluster;

    Abstract : Origin-Destination (OD) matrix plays an important role in traffic management and urban planning. However, the OD estimation demands large data collection which has been done in past mostly by surveys with numerous limitations. READ MORE

  5. 4. Link flow destination distribution estimation based on observed travel times for traffic prediction during incidents

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Anna Danielsson; Gabriella Gustafsson; [2020]
    Keywords : incident management; logit model; route choice estimation; route set generation; traffic flow modelling; traffic prediction;

    Abstract : In a lot of big cities, the traffic network is overloaded, with congestion and unnecessary emissions as consequence. Therefore, different traffic control methods are useful, especially in case of an incident. READ MORE

  6. 5. Traffic State Estimation for Signalized Intersections : A Combined Gaussian Process Bayesian Filter Approach

    University essay from KTH/Transportplanering

    Author : Michael Sederlin; [2020]
    Keywords : Traffic State Estimation; Traffic Flow modelling; Gaussian Processes; Bayesian Filtering; Kalman Filter; Traffic Signals; Intersection; Non-parametric;

    Abstract : Traffic State Estimation (TSE) is a vital component in traffic control which requires an accurate viewof the current traffic situation. Since there is no full sensor coverage and the collected measurementsare inflicted with random noise, statistical estimation techniques are necessary to accomplish this. READ MORE
