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

    Author : Ingrid Johansson; Xiaoliang Ma; Wilco Burghout; Henrik Pettersson; Xiaobo Qu; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 17. Timetable Analysis based on Social Cost and Simulation

    Author : Jennifer Warg; Markus Bohlin; Oskar Fröidh; Carl-William Palmqvist; Paola Pellegrini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway capacity allocation; timetable analysis; social costs; microscopic railway simulation; macroscopic railway simulation; passengers; timetable performance; early departing freight trains; Järnvägskapacitet; tidtabellsanalys; sociala kostnader; mikroskopisk järnvägssimulering; makroskopisk järnvägssimulering; resande; tidtabellseffektivitet; tidiga godståg; Transportsystem; Transport Systems;

    Abstract : The timetable is essential for railway traffic. Its design affects rail operations – and by extension all operators, passengers, and freight clients. International practice for capacity allocation varies and there is no common algorithm for designing and evaluating timetable changes. READ MORE

  5. 18. Hierarchical Modeling of Road Traffic Networks

    Author : Eugene Merritt; KTH; []
    Keywords : traffic simulation models; calibration and validation; field data collection;

    Abstract : The main objective of the thesis was to develop and applymethodologies for analysis and evaluation of the applicabilityof different types of road traffic simulation models for urbantraffic conditions. For this purpose a number of models ofmacroscopic, mesoscopic and microscopic type were applied,calibrated, validated and analyzed using extensive field datacollection to obtain traffic flow, travel time and queue-lengthdata for major road networks in Stockholm and Uppsala.

  6. 19. Developing Microscopic Traffic Simulation Models for the Transition Towards Automated Driving

    Author : Ivan Postigo; Clas Rydergren; Johan Olstam; Selpi Selpi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Vehicles with different capabilities for automated driving will gradually be deployed in road transportation systems over the coming decades. Mixed traffic conditions may change the characteristics of the traffic flow dynamics. Microscopic traffic simulation is used for studying traffic flow dynamics in transportation systems. READ MORE

  7. 20. Modelling of Traffic Performance for Swedish Roads and Motorways

    Author : Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

    Abstract : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. READ MORE
