Why not just use a phone that supports Google Latitude? http://www.google.com/latitude/intro.html. All the work has been done for you.

It's one thing to monitor traffic for things like accidents and traffic jams, but NYC traffic is its own beast. While there are certain times of the day (morning/evening rush periods, midday lunch, etc) when there is heavy congestion that lasts for an hour at a time, a lot of times you get these little jams due to someone double parking, etc that lasts for 25-30 minutes tops. And they're more or less randomly distributed around the residential areas of Manhattan. Constantly rerouting to avoid these situations in NYC sounds like a nightmare. For instance, you could avoid all the congestion but take a circuitous route (25-30 minutes local - downtown to uptown), or you could sit through 10 minutes of congestion to get onto the FDR or West Side Highway + 15 minutes of driving. In the end, you're better off just listening to the cabbie for advice. While it's possible he might want to rip you off, more often than not, he wants to get you to your location fast for A) a better tip and B) so he can get more cab hires a day.

There are numerous monocular depth cues available, but you won't "see" in 3D; you'll just know you're viewing a 3D world. The answer to you question depends on what exactly you're referring to by "simulate 3d."

If it's just depth perception, then.. you can use motion parallax, occlusion, kinetic depth perception (when objects change size, while your viewpoint remains fixed), perspective lines, spatial frequency/texture gradients, etc..
