Weather Impact on Floating Car Data

Kurzfassung

Floating Car Data (FCD) is an accepted data source for capturing traffic states, especially in urban regions. If obtained from running fleet management systems, they are cheap to acquire, nearly no investments into the infrastructure are necessary. Since these data are very “noisy” – which means traffic state information generated from single vehicles vary very much – approaches exist how to obtain reliable traffic state information even from very sparse FCD. Within this paper the influences weather conditions have on the daily speed variation curves derived from FCD are shown. This information is very meaningful for prediction applications and can be taken into account in historical data analysis.
