Joint project OD-FCD - Identification of traffic relations from the fusion of floating car data with traffic intensity measurements
The knowledge of the current traffic relations in road networks is an essential basis for advanced traffic management procedures. The capacities of the traffic networks can only be used optimally if the traffic demand as well as the travel times of the routes are known. With these inputs, the traffic flow on the network can be distributed efficiently. This knowledge represents the core information of almost all traffic management procedures, such as change direction signs, construction site management or light signal control in urban road networks. However, this essential information cannot yet be measured at a reasonable cost. For this reason, traffic management procedures usually use simple assumptions about traffic relations in order to achieve the best possible use of the existing traffic infrastructure.
It is now possible to determine this basic information of traffic management up-to-date and with high accuracy by means of a suitable fusion of mass data. Such data is the data obtained from detector loops and probe vehicles data or so-called Floating Car Data (FCD).
