  1. 1. Är Stockholm anpassad för synskadade?

    Kandidat-uppsats, KTH/Transportplanering

    Författare :Helin Celep; Victoria Remmel; [2021]
    Nyckelord :Visual impairment; blindness; accessibility; color contrasts; urban environment; Synnedsättning; blinda; tillgänglighet; ledstråk; kontrastmarkeringar; stadsmiljö;

    Sammanfattning : There is a lot of talk about the necessity of creating accessibility within cities, but is it created for everyone? A multitude of different disabilities exists and this study focuses on the accessibility for the visually impaired in Stockholm. Persons with visually impairment have it more difficult to participate in the physical and social environment on the same terms as a person with full vision, and it is therefore important to create an environment where they can participate.

  3. 2. Data-driven methods for estimation of dynamic OD matrices

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Ina Eriksson; Lina Fredriksson; [2021]
    Nyckelord :Large-scale mobility data; Dynamic OD matrix; Unsupervised learning; Sensor fusion; Kalman filter; Principal component analysis; Online estimation; OD estimation;

    Sammanfattning : The idea behind this report is based on the fact that it is not only the number of users in the traffic network that is increasing, the number of connected devices such as probe vehicles and mobile sources has increased dramatically in the last decade. These connected devices provide large-scale mobility data and new opportunities to analyze the current traffic situation as they traverse through the network and continuously send out different types of information like Global Positioning System (GPS) data and Mobile Network Data (MND).

  4. 3. Analysis of vehicle route choice during incidents

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Joakim Janmyr; Daniel Wadell; [2018]
    Nyckelord :Route choice; Map matching; Route set generation; GPS traffic observations; Inferring paths from GPS observations;

    Sammanfattning : The use of GPS observations for investigating routing behaviors can be a good alternative to using more traditional traffic simulation models. In this paper, a method for inferring paths from GPS observations is proposed. Further, a route set generation algorithm is implemented. LÄS MER

  5. 4. Hantering av säkerhetsfarliga fel inom järnvägsinfrastruktur utifrån tillståndsbedömning med mätvagn

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Mohammad Taha; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A train accident at high speeds can result in serious consequences, and in worst case the loss of human life. Hence, there are stringent requirements related to traffic safety on the railway system. These requirements are valid for both the infrastructure and the rolling stock. LÄS MER
