    External research report
    Open Access
    Response of emergency units after natural disasters, such as earthquakes, has to be coordinated, fast and efficient in order to rescue and care for the victims, keeping all the population –and the units themselves– safe ...

  • Multi-vehicle route planning for efficient urban freight transport 

    Mrazovic, Petar; Eser, Elif; Ferhatosmanoglu, Hakan; Larriba Pey, Josep; Matskin, Mihhail (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    The urban parking spaces for loading/unloading are typically over-occupied, which shifts delivery operations to traffic lanes and pavements, increases traffic, generates noise, and causes pollution. We present a data ...
