1. A system for monitoring and supervising potential traffic infraction events, said system comprising:

  • a single potential traffic infractions detector;

    one or more image capture devices; and

    a single multi-thread capture routine configured to simultaneously generate a distinct thread for each one of a plurality of potential traffic infraction events occurring at least one of almost simultaneously or simultaneously in a same lane or in different lanes of a road, each distinct thread containing therein a complete record of simultaneously captured images of an associated one of the plurality of potential traffic infraction events,wherein;

    separate and distinct threads of different traffic infractions may be simultaneously or almost simultaneously generated using the same one or more capture devices as another distinct and separate traffic infraction violation thread;

    as many separate and distinct threads as a previously programmed number of frames per second may be created until fulfilling a total time of a pre-event;

    upon creation of a circular buffer of the many separate and distinct threads, at least one thread that exceeds the total time of the pre-event is discarded and at least one new separate and distinct thread is simultaneously created to replace the at least one thread having been discarded;

    each circular memory buffer discards an oldest frame upon input of each new framein response to at least one of the plurality of potential traffic infraction events resulting in an actual traffic infraction event, the single thread capture routine is further configured to identify, retain, and use a thread having therein a complete record of simultaneously captured images of the actual traffic infraction event, and to simultaneously therewith create a new thread to replace the thread having been identified and used;

    capture of the actual traffic infraction event is performed in real-time; and

    in response to two potential traffic infraction events occurring within a few thousandths of a second of difference between one another, the single thread capture routine is further configured to create one or more backup threads and to save the backup threads frames of pre-events existing in a sole capture thread, such that, upon occurrence of one or more actual traffic infraction events associated with the two potential traffic infraction events, each backup thread thereupon saves necessary images in real-time for the each of the backup threads.
