FLOATING CAR DATA
Floating Car Data (FCD) are information on traffic conditions which are based on the current position data which comes from fleet vehicles of Princip Company.
The position data of each vehicle are being sent regularly to central application server for evaluation of current traffic state.
The road network is divided to sections according to the localization database. These sections describes the most important road segments used by regular traffic.
One section of localization database is identical to the distance between two road intersections that have a significant influence on the traffic flow distribution over the road network in the city.
Based on position data of each vehicle in the fleet the level of traffic load is evaluated in particular section of localization database.
The traffic level value is shown in the four level scale, where the first level represents the minimum traffic load in the section (normal traffic flow speed),
and the fourth level is the maximum traffic payload of the section which corresponds with congested state of traffic.
The map shows only the current data which were calculated. If there is no valid value in the section or the calculated value is older than 10 minutes, the section traffic state is not displayed.
