"Traffic Viewer" is a free software for visualization. Once it is installed in a mobile phone, it shows, in real time, the lastest screeshots performed by the traffic cameras located in Madrid, Barcelona, Bilbao, Sevilla, Valencia, Vigo, Toledo, Alicante, Palma de Mallorca, Granada, Logroño... etc. and surroundings (M40, M50, A1, A2...), which belong to their City Councils and DGT. Also, it shows for Madrid the status of roads which might be congested (each 5 minutes the information is refreshed) and for Santa Cruz de Tenerife.
