The idea consists in posting virtual tags close to speed cameras in order to warn the other drivers. These users will then get an alarm when they are closer than 15 seconds to a critical point, and a red point locating the speed camera appears on their screen. You can signal a fixed speed camera by pressing the key "1" of your mobile phone, a mobile one by pressing key "2" and that a camera disappeared (you get an alarm but you do not see any speed camera) by pressing "0". You are also invited to signal speed cameras that have already been tagged; by confirming their presence, you create trust links with other users and get more reliable information. The system excludes automatically users that do not vote "like the others". Roughly speaking, the more you participate, the more the information you get is reliable. FoxyTag is a "collaborative" system. Tags posted by FoxyTag are directional. So, tags posted for users driving in the opposite direction won't be signalized to you.
FoxyTag motivates neither speeding nor any other risky behavior, but allows the driver to concentrate on the road instead of having is eyes fixed on the speedometer, by fear of being flashed. We observe that drivers tend to brake suddenly when they see a speed camera (even if they are not speeding), which can provoke traffic jams or even accidents (chain collisions or slidings, like in this video). FoxyTag signals in advance the presence of speed cameras, so that the driver has enough time to check his speed and adapt it if necessary.
Proposed for free by the company arx iT, FoxyTag is used for scientific researches leaded by Michel Deriaz at Geneva University.
