1. A hazardous vehicle alert system comprising:

  • a control module, comprising;

    a processor, a data storage medium, and a software package;

    a graphical user interface, comprising;

    at least one display screen, at least one hand operated control, a required reaction time input, a minimum vehicle speed input, and a minimum vehicle distance input,a vehicle speed and distance detection device with an operating range of at least 1500 feet and a conical-shaped send and capture operational zone;

    an alert module; and

    at least one power source, whereinsaid control module is controllably coupled to said graphical user interface, said vehicle speed and distance detection device, and said alert module, and electrically coupled to said at least one power source,said graphical user interface, said vehicle speed and distance detection device, and said alert module are electrically coupled to said at least one power source,said software package is installed on said data storage medium and produces said graphical user interface on said at least one display screen, where said inputs may be adjusted with said at least one hand operated control, with data transfer essentially continuously flowing between said graphical user interface and said data storage medium through said processor, which executes a set of instructions contained in said software package,said instructions including the continuous update of required reaction time input, said minimum vehicle speed input, and said minimum vehicle distance input in said graphical user interface according to the relationship;

    said reaction time input=said minimum vehicle distance input/said minimum vehicle speed input, where the most prior adjusted input parameter between said three input parameters is held constant during said continuous recalculation, where the most prior adjusted input parameter is a rolling designation as input parameters are iteratively adjusted, until the final said three input parameters is chosen by the user and saved into said control module,said control module sends commands to said vehicle speed and distance detection device for it to report back to said control module with the actual vehicle speed of detected vehicles at designated said minimum vehicle distance location; and

    in response to said speed reports from said vehicle speed and distance detection device to said control module, said control module sends commands to said alert module to start an alert process when it receives vehicle speed measurements at or above said minimum vehicle speed at said minimum vehicle distance, thereby alerting personnel to hazardous vehicles.
