What services provide realtime (or daily-updated) basic traffic informations for Western Europe ?
For example, traffic.com/Navteq provides such data to Bing Maps for US/Canada and Microsoft suggests CENTRICO/OTAP for Europe in its documentation (which is outdated, EasyWay seems to have replaced this service), but its website is slightly confusing.
Are there other major actors in this market for Europe ?
For example, One Step Ahead seems to provide [free] data for Germany, Netherlands and Belgium, but it's a single file per country (hence not tiled data), and I'm not sure how often it is updated.
