Tourists and busy New Yorkers don't have time to waste on subway delays, road construction and traffic jams. Finally, they don't have to. Thanks to two travel information services offering real time updates on public transit and car travel, it's now actually possible to plan a trip armed with up-to-date travel information on accidents, construction and other mass transit and transportation conditions. One such service is the popular, multi-city Web site Hopstop. The latest entrant into the NYC real-time travel information marketplace is "511 NY," launched in October 2009. 511, which provides information from its Web site, or by telephone (but not via PDA mobile, yet) is a serviced provided by New York State.

The best news for tourists and residents alike is that both Hopstop and 511 NY are free.
