On vehicular traffic data analysis — •Martins Brics and Reinhard Mahnke — Institute of Physics, Rostock University, Germany

This contribution consists of analysis of empirical vehicular traffic flow data. The main focus lies on the Next Generation Simulation (NGSIM) data. The first findings show that there are artificial structures within the data due to errors of monitoring as well as smoothing position measurement data. As a result speed data show discretisation in 5 feet per second.

The aim of this investigation is to construct microscopic traffic flow models which are in agreement to the analysed empirical data.

The ongoing work follows the subject of research summarized by Christof Liebe in his PhD thesis entitled "Physics of traffic flow: Empirical data and dynamical models" (Rostock, 2010), see http://rosdok.uni-rostock.de.
