Abstract:
1. A method for monitoring speed of a vehicle moving in a speed controlled road section of a road, said vehicle having a computing system therein, said speed controlled road section comprising a plurality of risk zones, said plurality of risk zones comprising a high risk zone that includes a posted speed limit at a location in the high risk zone, said method comprising: determining real-time road information pertaining to road conditions for each risk zone; storing the determined road condition information in the computing system; determining a threshold speed of the high risk zone as equal to the posted speed limit; determining a threshold speed of each risk zone other than the high risk zone, based on the stored road condition information and on a distance from each risk zone other than the high risk zone to the location of the posted speed limit within the high risk zone; storing the determined threshold speed of each risk zone in the computing system; determining a geographical position of the vehicle while the vehicle is moving in the speed controlled road section; storing the determined geographical position of the vehicle in the computing system; determining a current risk zone of the plurality of risk zones in which the vehicle is moving, based on the stored geographical position of the vehicle; determining a current speed of the vehicle moving in the current risk zone; ascertaining that the current speed of the vehicle exceeds the stored threshold speed of a particular risk zone selected from the group consisting of the current risk zone and another risk zone of the plurality of risk zones; and responsive to said ascertaining, performing an action selected from the group consisting of triggering an alarm within the vehicle, presenting a message to a driver in the vehicle, automatically regulating the speed of the vehicle by the computing system, and combinations thereof, wherein the action is specific to the particular risk zone and dependent on the stored road condition information.
