It is a known fact that most accidents today result from human errors. Common are excessive lane switching and repeated acceleration changes. Nevertheless, most modern vehicles are equipped with various sensors and measurement devices. In light of the above, we have fabricated a real-time device aimed to automatically alert dangerous driving. The control system is a five sub-system assembly. (1) A Global Positioning System. (2) An acceleration gauge. (3) On-board diagnostic system (OBD). (4) RF transmitter. (5) A General Packet Radio Service (GPRS).

The GPS system was used as a basic logging tool, which provided position and velocity as well as the vehicles course. The gauge was applied to measure extreme driving behavior like turns, brakes and excessive lane switching. OBD system measures motor operation data such as load & fuel consumption. In order to alert near drivers an RF transmitter was used. An alert is transmitted whenever a driver commits a dangerous maneuver. GPRS transmits data to an internet server in order to (1) notify authorities whenever needed, (2) identify traffic jams and (3) provide technical information for car service providers. A graphic user interface for the driver was designed, which includes RPM indication, velocity scale (taken from both OBD and GPS) and a gas consumption scale. A separate interface was designed for research needs, showing all measured parameters such as incline, acceleration, engine information etc. Remark: both interfaces may alert the user when improper driving occurs, and indicate the suggested speed.
