CFVD™ was developed by Israel based Estimotion Inc. which was founded in July 2000 and was acquired by ITIS in December 2003.
CFVD is patented technology, which provides a unique, and high quality system for measuring and forecasting real time traffic flow based on anonymously sampling the positions of mobile phones. Whilst an individual record of a mobile phone's position is typically less accurate than a corresponding GPS record, this is compensated by the large number of mobile phones on any road, knowledge of the underlying road network and the application of statistical techniques.
ITIS has developed full working sites, using live mobile phone data in the Tel Aviv area of Israel, Antwerp in Belgium and in Baltimore and has successfully calibrated the results against traffic simulation models and loop data. ITIS has a US patent with 149 claims for this technology which complements the US patent Instantaneous Traffic Monitoring System which the company
acquired on 1 November 2002. |
