  1. 1. Driver Modeling based on computational intelligence approaches : exploaration and Modeling driver-following data collected by an instrumented vehicle

    Författare :Xiaoliang Ma; Karl-Lennart Bång; Mark Dougherty; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is concerned with modeling of driver behavior based on data collected from real traffic using an advanced instrumented vehicle. In particular, the focus is on driver-following behavior (often called car-following in transport science) for microscopic simulation of road traffic systems. LÄS MER

  3. 2. Advance Traffic Signal Control Systems with Emerging Technologies

    Författare :Junchen Jin; Xiaoliang Ma; Iisakki Kosonen; Henrik Pettersson; Ruey Long (Kelvin) Cheu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transportvetenskap; Transport Science;

    Sammanfattning : Nowadays, traffic congestion poses critical problems including the undermined mobility and sustainability efficiencies. Mitigating traffic congestions in urban areas is a crucial task for both research and in practice. LÄS MER

  4. 3. Simulation Studies of Impact of Heavy-Duty Vehicle Platoons on Road Traffic and Fuel Consumption

    Författare :Ingrid Johansson; Xiaoliang Ma; Wilco Burghout; Henrik Pettersson; Xiaobo Qu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; microscopic traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; Transportvetenskap; Transport Science;

    Sammanfattning : The demand for road freight transport continues to grow with the growing economy, resulting in increased fossil fuel consumption and emissions. At the same time, the fossil fuel use needs to decrease substantially to counteract the ongoing global warming. LÄS MER

  5. 4. Discovering Contiguous Sequential Patterns in Network-Constrained Movement

    Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Clas Rydergren; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; map matching; trajectory pattern mining; closed contiguous sequential pattern mining; trajectory pattern visualization; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : A large proportion of movement in urban area is constrained to a road network such as pedestrian, bicycle and vehicle. That movement information is commonly collected by Global Positioning System (GPS) sensor, which has generated large collections of trajectories. LÄS MER

  7. 5. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data

    Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Mirco Nanni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; map matching; contiguous sequential pattern mining; contiguous sequential pattern comparison; movement pattern detection; Kartmatchning; sammanhängande sekventiellt mönster utvinning; sammanhängande sekventiellt mönster jämförelse; rörelsemönster detektering; Geoinformatics; Geoinformatik;

    Sammanfattning : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.
