Statistical analysis of high-flow traffic states

Abstract

We present an analysis on the characteristics of so-called high-flow states of traffic, i.e. traffic states where the flow rate exceeds 50 vehicles per minute and lane. We investigate the duration, frequency and other statistics of such states. Moreover, we study the conditions under which they occur. The factors that influence the existence and occurrence of high-flow states in traffic are, for instance, the fraction of slow vehicles, themotorways’ general topology (e.g. number of lanes, slope, interchanges, ramps and exits), the flow rate on neighboring lanes, the hour of the day and day of the week.
