Your mobile phone or navigation device alerts you as you approach police speed traps.
HOW DOES TRAPSTER WORK?
When you see a trap, report it by pressing a button on your phone, or calling a toll free number. Other user's phones will alert them as they approach the trap. Trapster learns the credibility of traps based on how many users agree. It also learns the credibility of each user, over time.
So how does it work? Our goal is to make it so simple that you don't need to know. But in case you are interested, it combines technologies such as GPS and wireless location, voice transcription, geocoding, reverse geocoding, and SMS, with a central database server. It communicates in real time, using the Internet.
