Enhancing Short-Term Traffic Prediction for Large-Scale Transport Networks by Spatio-Temporal Clustering

Congestion in large cities is responsible for extra travel time, noise, air pollution, CO2 emissions, and more. Transport is one of the main recognized contributors to global warming and climate change, which is getting increasing attention from authorities and societies around the world. Better utilization of existing resources by Intelligent Transport Systems (ITS) and digital technologies are recognized by the European Commission as technologies with enormous potential to lower the negative impacts associated with high traffic volumes in urban areas.

The main focus of this work is on short-term traffic prediction, which is an essential tool in ITS. In combination with providing information, it enables proactive decisions to decrease severity of congestion that occurs regularly or is caused by incidents. The main contribution of this work is to develop a methodological framework and prove its enhancing effects on short-term prediction in the context of large-scale transport networks. It is expected to contribute to more robust and accurate predictions of ITS in traffic management centers.

The Centre for Traffic Research celebrates its 25th anniversary!

The Center for Traffic Research (CTR) was established in 1996 by the Royal Institute of Technology (KTH) and the Swedish National Road and Transport Research Institute (VTI) on the initiative of the then Swedish Road Administration (Vägverket) to gather and develop expertise in road traffic processes. The original name was Center for Traffic Simulation. Linköping University (LiU) soon joined as a partner.

Until 2012, Professor Ingmar Andreasson led CTR. Since Ingmar's retirement in 2012, Dr. Wilco Burghout has been the director of CTR, where he himself has researched and completed his doctorate.

CTR's research areas range from data-driven traffic predictions to modeling of multimodal transfer nodes, motorway traffic control, connected vehicles and micromobility.

Hitherto, CTR's research has produced over 200 research reports and scientific articles, as well as 17 doctoral degrees. Today, 22 researchers are linked to CTR, which has an annual budget of SEK 9 million with the Swedish Transport Administration (Trafikverket) as the largest financier.
