of the current Traffic 4 England 'free' status. The application is in its 'trial' phase, where you get to use it for free if you want. By the end of the year this trial phase will terminate and Traffic4England will no longer be available for free on the Android Market place.
For those that are unclear, we didn't make Traffic4England free for a limited time to 'trick' people into downloading it. We made it available for free to gather user feedback about its usefulness, and for people to get an opportunity to see if it was the type of product that would be useful to them.
If people are confused by the time limited nature of the product, we suggest that they uninstall it and use one of the other traffic apps on the marketplace.

The GPS function with Traffic4England is designed to provide an approximate location to base the traffic events.
Depending on when and where you use the GPS system, the accuracy will be anywhere between within 5 meters to within 5000 meters. Then android gets a GPS 'fix' it then attempts to do whats call reverse geocoding, which effectively calls the Google Map servers and ask them if they've an address for the current longitude/latitude position. Somethings there will be a full address, sometimes where won't, somethings it will be within 5 metres of where you are, sometimes it won't. The accuracy varies depending on where you are.
The GPS feature is there to provide a 'best effort' at placing your location so that the distance to the nearest traffic events realistic. Depending on the prevailing conditions, sometimes it will be accurate, sometimes it won't.
If you need to check, fire up the standard Google maps on Android and use the locate function. Tap the 'current location' marker to get it to show the accuracy in meters of the current GPS reading. This reading is effectively the best Traffic4England can do.
