Floating Car Data
PTV can use so-called floating car data (FCD) to calculate up-to-date traffic data. Vehicles that serve as mobile data collection devices provide information about the current traffic situation. Anonymised data is transmitted via mobile phone networks to the FCD control centre. The FCD data record contains the current geographic coordinates and information on the precise time. As a result, all driving conditions can be modelled, even queues of standing traffic on motorways or at traffic lights, for example. The data is geocoded on a map based on the communication between the vehicles and the FCD control centre. The FCD control centre notifies all FCD participants of alternative routes as soon as an incident occurs.
Using floating car data in PTV's TrafficPlatform
PTV's TrafficPlatform not only uses stationary measurement data that is collected by means of conventional detectors, but also mobile measurement data that is included in numerous advanced traffic management systems. FCD helps planners to significantly improve the accuracy of analysis and forecast methods. The FCD harmoniser embedded in PTV's traffic platform ensures that the traffic management system can immediately use the data generated by each vehicle.
In addition to data collection and import of position reports, it is possible to model road network data. Traffic-related information can thus be calculated and then be aggregated.
