Available for absolutely nothing, Waze is an Android / iPhone / BlackBerry / Nokia application which works by sharing data between users. By sharing and collecting information on progress by other users it’ll help build a picture of road conditions. Their Live Map shows some of the reports – including notifications of speed traps, jams and obstructions.
The makers freely admit that their “driving community” has only just started developing and there’ll be a fair bit of data usage but it might be worth a try if other sat-nav software and traffic apps have left you flat.
