Unambiguous metrics for evaluation of traffic networks

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 known by the research partners. Afterwards, a set of base measures has been defined. Using that set, clear formulas for all metrics have been derived and are reported in this paper. Finally, an application example about a cooperative traffic light controller is given.
