A system for characterizing the driving style of vehicle drivers

An assessment system of a risk indicator of the vehicle driver is disclosed, which uses an accelerometer (21) to detect acceleration and deceleration values (A, D, I) of a vehicle, a GPS (22) to detect position (L, G) and speed (V) of the vehicle and a GSM/GPRS module (24) to send the detected data to an operations center (300) that calculates the assessment of the risk indicator of the vehicle driver.
