SECTION OVERSPEED WARNING APPARATUS AND SYSTEM

In a section overspeed regulating method of determining whether a vehicle overspeeds on the basis of whether an average speed of the vehicle in a regulation section exceeds a speed limit, the section overspeed warning apparatus and system determine whether the current speed of the vehicle traveling on a regulation section exceeds the speed limit, and warn a driver. Whether the speed of the vehicle traveling on the regulation section exceeds the speed limit of the section is determined depending on a travel distance from a starting position of the regulation section to a current position of the vehicle, a travel time taken for the vehicle to travel by the travel distance, and a remaining distance from the current position of the vehicle to an end position of the regulation section. If it is determined that the current position of the vehicle will exceed the speed limit of the section, overspeed warning messages are output in the form of text, voice, or warning sound. Further, the section overspeed warning apparatus and system recommend the maximum speed, which allows the vehicle not to violate the speed limit of the section at the current position, to a driver as a recommended speed.
