1. 1. Data-driven methods for estimation of dynamic OD matrices

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

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

   Abstract : 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).

3. 2. Daily pattern recognition of dynamic origin-destination matrices using clustering and kernel principal component analysis

   University essay from KTH/Transportplanering

   Author : Zhiwu Dong; [2021]
   Keywords : origin-destination; pattern recognition; principal component analysis; kernel principal component analysis; k-means cluster; ursprung-destination; mönsterigenkänning; huvudkomponentanalys; analys av kärnhuvudkomponent; k-medelkluster;

   Abstract : Origin-Destination (OD) matrix plays an important role in traffic management and urban planning. However, the OD estimation demands large data collection which has been done in past mostly by surveys with numerous limitations. READ MORE

4. 3. Dynamic Link Flow Estimation according to Historical Travel Times

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

   Author : Mahdi Abrishami; [2017]
   Keywords : DNLTT Algorithm; DTA model; Dynamic Network Loading; OD Demand Optimization; Historical link Travel Times;

   Abstract : Vast application of ITS and the availability of numerous on-road detection devices has resulted in variety of alternative data sources to be exploited and used in the field of traffic modelling. In this thesis, historical travel times, as an alternative data source, is employed on the developed method to perform dynamic network loading. READ MORE

5. 4. Evaluation of Load Balancing Algorithms in IP Networks : A case study at TeliaSonera

   University essay from Institutionen för teknik och naturvetenskap

   Author : Emil Hasselström; Therese Sjögren; [2005]
   Keywords : Technology; Load balancing; Traffic engineering; MPLS; OD Matrix; Simulation; TEKNIKVETENSKAP;

   Abstract : The principle of load balancing is to distribute the data load more evenly over the network in order to increase the network performance and efficiency. With dynamic load balancing the routing is undated at certain intervals. This thesis was developed to evaluate load balancing methods in the IP-network of TeliaSonera. READ MORE
