This site is no longer active as of 16 March 2011. The traffic feed from which it took it's data has been switched off. This is a decision that is out of my hands I'm afraid. The data was provided as part of the backstage BBC initiative as as such was never likely to be permanent.
The application was used to teach myself GWT and as such I guess it was successful. In it's earliest form it was one of the very first sites of it's kind. Map sites seem old-hat now but you will have to believe me that this looked mighty impressive in 2006. I still haven't seen anyone reproduce the timeline view.
Many thanks to all the people who used this site and thanks for all the support over the years. I might get time to resurrect it maybe using the Highways Agency RSS feed but not for the moment.
