Yahoo Incorporated"s free online mapping service will begin giving driving directions in 34 European countries as part of an upgrade aimed at luring traffic away from rivals AOL and Google. In April, AOL"s industry-leading Mapquest service attracted 49.2 million U.S. visitors, a 3% increase from last year, while traffic to Google"s maps surged 49% to 30.8 million visitors, according to comScore Media Metrix. Meanwhile, U.S. traffic to Yahoo maps declined 5% to 29.4 million. The Sunnyvale-based company also said it will feature more landmarks and other visual cues to help people find their way around. By relying on new software, Yahoo believes its maps will be more accurate, too.
