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-difference to the lead vehicle. This seems to be a causal...
Microscopic traffic simulation models are applied in the analysis of transportation systems for years. Nevertheless, calibration (and validation) of microscopic sub-models such as car-following and gap-acceptance models is still a recent matter. The objective of the calibration is to adapt the simulation output to empirical data by adjusting the model's parameters. However, simulation results may...
This paper presents an extensive set of unambiguous metrics that can be used for evaluation of new ITS applications. Currently in the literature most authors define their own metrics and small differences in definitions can lead to confusion when comparing the results. To derive the set of metrics presented in this paper, several steps have been taken. First, a list has been made with all metrics...
