Answered By: 
Peter Hendy (Commissioner, Transport for London)

In 2003, ITIS Holdings had 50,000 vehicles supplying data to their system and we understand this number has not increased since then. The number of working probes, however, has increased from around 31,000 in January 2004 to around 40,000 in 2006.
