Sometime last year I discovered BBC Backstage, a selection of feeds and resources provided by the BBC for developers. Having re-discovered these pages recently, I decided it would be fun to integrate one of the traffic feeds with Google Maps. My attempt at plotting the Southampton feed can be found here. The main interface is written in XHTML and AJAX, whilst a PHP script running in the background parses the TPEG feed provided by the BBC and outputs XML data containing a list of traffic problems.
