By analyzing a large data-base of car-driving data in a generic way, a few elementary facts on car-following have been found out. The inferences stem from the application of the mutual information to detect correlations to the data. Arguably, the most interesting fact is that the acceleration of the following vehicle depends mostly on the speed-dif...

As part of the "dNet Bayern" project, it is planned to control the large-scale network of federal freeways in Bavaria by means of variable traffic signs. Due to the partly very low detection density, it is conceived to derive a reliable detection of incidents by means of a directly measured travel time and to derive control strategies for large-area network meshes. The aim of the project is to develop an automatic incident detection algorithm based on Bluetooth detection. Different approaches and methods are investigated in order to develop a fast as well as robust algorithm for incident detection based on the raw data of the sensors. A further focus is on the estimation of capacity constraints in case of a detected incident.
