1. An autonomous in-vehicle virtual traffic light system comprising:

  • a) an in-vehicle apparatus further comprising;

    i) at least one memory comprising computer program code for one or more programs;

    ii) a database comprising;

    (i) position coordinates of track points along the center line of roads and at center points of intersections for determining geographic sections and leg segments of intersections, wherein the position coordinates of track points are arranged in database tables and one or more table represent one or more geographic section;

    (ii) predefined leg segments associated with predefined intersections;

    (iii) a plurality of predefined cases and threshold delay times;

    (iv) green and turning times associated with the predefined cases;

    (v) red and turning times associated with the predefined cases; and

    ,(vi) position coordinates of track points along the center line of roads for determining road sign image IDs, and road sign images associated with the road sign image IDs, wherein the position coordinates of the track points are arranged in database tables and one or more table represent one or more geographic section;

    iii) at least one GPS receiver module to enable the vehicle to determine its position coordinates, speed, course and date/time at real-time status; and

    ,iv) at least one processor being coupled to said database and said memory;

    b) a visual display coupled to said in-vehicle apparatus, and able to present visual and audible information, wherein the visual information comprises traffic signal phases and images of road signs, wherein the audible information comprises, indicating traffic signal phases, indicating road sign images, and indicating alerts;

    wherein the system mimics conventional traffic signal systems and neither depends on vehicle to vehicle communication nor vehicle to intersection or road sensors communication nor vehicle to wireless network communication.
