A must-have iPhone application for people who drive a lot is “Trapster” the app for avoiding speed traps. Or a better description by Paul Carr before he was fired from The Guardian: “Yes, that’s Trapster: the mobile distraction for when driving at high speed isn’t fucking dangerous enough.”

The free program uses the GPS receiver built into new iPhones to track a driver’s location and warn of nearby speed traps and red light cameras. It’s also available for phones running Google Android and some BlackBerries.  Drivers can add new locations to the app by hitting buttons to mark speed traps and red light cameras for other drivers. Users can also rate the accuracy of speed trap reports, which helps weed out fake inputs.

It’s been nearly a year since the debut of Trapster, a controversial but popular app that alerts you of nearby speed traps, cameras, and the like. It’s had more than 1 million downloads, and is “getting about 50,000 downloads a day right now” to add to that.

Version 3.5 released back in September, bringing with it some impressive–and, for many users, long-awaited–new features. Here’s the rundown ((courtesy of CNET):

• Improved interface Five features (some of them new) are now accessible by tapping blue icons that span the right side of the screen.
• Bluetooth audio If your car supports Bluetooth, you can pair Trapster to your stereo to get audio alerts over your speakers. Even better, if your car supports A2DP (i.e. stereo Bluetooth), you can take advantage of:
• Built-in iPod controls Tap the little musical-note icon to slide open Trapster’s iPod audio controls. Obviously, you don’t need stereo Bluetooth to use them, but it sure is a nice combo.
• Rotating maps Trapster tacks your position in real-time on a moving map. Now, that map can rotate depending on your direction of travel rather than staying in “always-North” mode. The top blue icon toggles this feature on and off.
• Real-time traffic The bottom blue icon slides out a Google Traffic map, which shows you trouble spots in your area. Handy, but it’s too bad the developers could’t integrate this with the main map instead of requiring you to view a second one.

Trapster crowdsources the data from its users who report speed traps.  This information is stored in the server and sharing with other Trapster users who come later near the same location, thus making the road safe . The more users, the more data, and the safer the roads are for speeders. The app potentially can help users speed or run lights more often. Nonetheless, police are largely supportive of Trapster, because they hope it will get users to slow down.

“Anything that gets people to slow down on the highway, or drive in a more responsible manner, is a good thing,” said Corinne Geller, public relations manager for the Virginia State Police.  She said the state itself uses that logic to announce some red light cameras and speed-limit enforcement areas.  “We don’t hide,” Geller said.

Here are some interesting stats from the Trapster website (as of Sep 10, 2009)
