    Abstract : Traffic congestion is increasing in almost all large cities, leading to a number of negative effects such as pollution and delays. However, building new roads is not a feasible solution. Instead, the use of the existing road network has to be optimized, together with a shift towards more sustainable transport modes. READ MORE

  2. 2. Analysis of Travel Patterns from Cellular Network Data

    Author : Nils Breyer; Clas Rydergren; David Gundlegård; Győző Gidófalvi; Linköpings universitet; []

    Abstract : Traffic planners are facing a big challenge with an increasing demand for mobility and a need to drastically reduce the environmental impacts of the transportation system at the same time. The transportation system therefore needs to become more efficient, which requires a good understanding about the actual travel patterns. READ MORE

  3. 3. Methods for Travel Pattern Analysis Using Large-Scale Passive Data

    Author : Nils Breyer; Clas Rydergren; David Gundlegård; Yusak Susilo; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Comprehensive knowledge of travel patterns is crucial to enable planning for a more efficient traffic system that accommodates human mobility demand. Currently, this knowledge is mainly based on traffic models based on relatively small samples of observations collected from travel surveys and traffic counts. READ MORE

  4. 4. Heavy-Duty Vehicle Platooning : Modeling and Analysis

    Author : Qichen Deng; Gunnar Flötteröd; Wilco Burghout; Clas Rydergren; KTH; []
    Keywords : Transportvetenskap; Transport Science;

    Abstract : Coupled with the growth of world economy, the demand for freight transport has escalated and will continue to do so. As the traffic intensity increases, the pressure on infrastructure, energy usage and environment becomes higher than ever. Meanwhile, the number of traffic accidents is also increasing year by year as a result. READ MORE

  5. 5. Transition Towards Fixed-Line Autonomous Bus Transportation Systems

    Author : Jonas Hatzenbühler; Erik Jenelius; Oded Cats; Clas Rydergren; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Buses; Public Transportation; Network Design; Resource Allocation; Simulation-based multi-objective Optimization; Transportvetenskap; Transport Science;

    Abstract : In the last years the steady development of autonomous driving technology has enabled the deployment of more mature autonomous vehicles. These vehicles have been applied in several pilot projects worldwide, most commonly in the form of small buses. READ MORE
