Abstract
A method for determining the traffic situation is based on traffic data which are obtained from reporting vehicles moving in the traffic, for a traffic network with traffic-controlled network nodes and roadway sections connecting them. Traffic data indicative of travel times on the roadway sections are obtained by reporting vehicles moving in the traffic, and are used to determine travel times on a roadway-section-specific basis. The mean number of vehicles in the queue, the mean number of vehicles, the mean vehicle speed outside the queue, the mean waiting time in the queue and/or the mean vehicle density outside the queue are determined from these travel times for the respective roadway section.
