And experts predict that the amount of data fed to fleet managers will increase by a similar amount over the next 10 years.
The trend shows why high quality reports are becoming the most important tool in fleet management, software specialist cfc solutions, which produced the figures, has claimed.
Managing director Jason Francis said: 'Ten years ago, the only data widely imported into fleet software was a floppy disc containing fuel card information.
'Today, data flows both in and out of fleet management software through interfaces with a multitude of sources including maintenance providers, insurance companies, tyre networks, human resources systems, accident management specialists and vehicle procurement sources.
'The potential contained in this information for making dramatic improvements in fleet management are enormous but not if the data is in its raw state.
'Going to the trouble of gathering this mass of information only makes sense if the right software reporting tools are available to automatically sort through the figures and recognise the areas where proactive management is required, and highlight them for the fleet manager.'
Francis added that the nature of fleet software reporting tools had not changed dramatically in more than a decade, and that a number of new approaches would be needed.
He said: 'This is one of the biggest challenges facing fleet software developers. While the reporting tools that we provide today are relatively sophisticated, they will almost certainly not be capable of handling the flood of information that could hit fleets over the next few years with widespread use of telematics systems, road tolls, congestion charging and even the satellite tracking of road use that has been recently mooted.'
