Speed trap detection and warning system

摘要

There is provided an apparatus and method for alerting the driver of a vehicle to a speed trap by monitoring the position of the vehicle against one or more databases of speed trap positions to determine whether the vehicle is within a predetermined distance of a speed trap. To reduce the incidence of false alarms, the database(s) or the data therein distinguishes between speed traps situated on a motorway and speed traps situated on other types of roads. When the vehicle is travelling on a motorway, the driver is alerted if the vehicle approaches within a predetermined distance of a motorway speed trap, but is not alerted if the vehicle travels within a predetermined distance of a non-motorway speed trap. <IMAGE>
