    Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER

  3. 2. A Traffic Simulation Modeling Framework for Rural Highways

    Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; Road: Traffic theory; Road: Traffic theory; Other technology;

    Sammanfattning : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. LÄS MER

  4. 3. Network-based Anomaly Detection for SCADA Systems : Traffic Generation and Modeling

    Författare :Chih-Yuan Lin; Simin Nadjm-Tehrani; Mikael Asplund; Aditya P. Mathur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure in society, such as electricity transmission and distribution systems. Modern SCADA systems are increasingly adopting open standards and being connected to the Internet to enable remote control. LÄS MER
