    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Christian Rosdahl; [2017]
    Keywords : Technology and Engineering;

    Abstract : In today’s society, traffic congestion is a major problem in several aspects. Apart from the obvious problem that people are losing valuable time due to the resulting delays, it also has negative impact on as well the economy as the local and global environment. READ MORE

  2. 2. Calibration of fundamental diagrams for travel time predictions based on the cell transmission model

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Christoph Seybold; [2015]
    Keywords : Cell transmission model CTM ; Fundamental diagrams; Calibration; Dynamic sources; Dynamic sinks; Split ratios;

    Abstract : Road traffic increases constantly and the negative consequences in the form of traffic jams can be realized especially in urban areas. In order to provide real time traffic information to road users and traffic managers, accurate computer models gain relevance. READ MORE

  4. 4. Framework for Calibration of a Traffic State Space Model

    University essay from Kommunikations- och transportsystem; Tekniska högskolan

    Author : Mats Sandin; Magnus Fransson; [2012]
    Keywords : traffic; framework; calibration; macro traffic model; ensemble kalman filter; cell transmission model;

    Abstract : To evaluate the traffic state over time and space, several models can be used. A typical model for estimating the state of the traffic for a stretch of road or a road network is the cell transmission model, which is a form of state space model. This kind of model typically needs to be calibrated since the different roads have different properties. READ MORE
