Many studies on drivers' speeding behaviour have been reported in the last decade. Most of the previous studies, however, have concentrated on the relationship between drivers' speeding behaviour and road/vehicle characteristics, without considering other important factors such as personal characteristics and drivers' perception of the speed limit. This paper analyses Korean drivers' speeding behaviour by taking into account such factors as trip characteristics in addition to personal, vehicular, and attitudinal factors. Speeding behaviour is measured by a categorical measure over the speed limit, and an ordered probit model is used to econometrically estimate the speeding behaviour equation. Results indicated that male drivers with higher income tend to drive faster, and experienced drivers drive at higher speeds than others; that vehicles with more horsepower and vehicles with safety features go slower than vehicles with less safety features; that trip distance and frequent use of the road are important factors for speed selection behaviour; and that perceived speed limit of the road and expectation of being caught for speeding are important factors for driving behaviour.
