Abstract
An apparatus and method for controlling a speed in an excess speed enforcement section are provided. The method includes determining one of a target speed, a lower limit speed, and a speed limit as a final target speed using a relationship between a target speed, a lower limit speed, and a speed limit. A required acceleration is calculated based on the final target speed and the vehicle speed and the vehicle speed is adjusted using the required acceleration.
