1. A system on-board vehicles for predicting a plurality of primary signs of driving while impaired or driving while distracted to reduce road-way accidents, and to prevent running red lights at predefined intersections by a traveling vehicle, the system comprising:
- a) in-vehicle cameras facing roads to monitor traffic lane lines;
b) in-vehicle automatic brakes;
c) the autonomous in-vehicle virtual traffic light system comprising;
an in-vehicle apparatus integrating with said automatic brakes and said cameras, the in-vehicle apparatus further comprising;
i) at least one memory comprising non-transitory computer readable media 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, leg segments of intersections, and the angles between the leg segments of each intersection;
(ii) predefined leg segments associated with predefined intersections;
(iii) a plurality of predefined cases associated with predefined intersections for generating in-vehicle virtual traffic signal phases autonomously; and
,(iv) road sign images for determining the speed limits and the traffic conditions of the roads;
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;
d) the autonomous in-vehicle virtual traffic light system further comprising 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 database and the computer program code are configured to, with the at least one processor, cause the in-vehicle apparatus to determine a plurality of parameters required by mathematic formulas of the system of predicting a plurality of primary signs of driving while impaired or driving while distracted, wherein said plurality of parameters comprise;
the status of the traffic signal phases at each upcoming predefined intersection;
the distance between the vehicle and each upcoming predefined intersection;
a deviation angle;
a perpendicular distance from the vehicle'"'"'s position to the line between two track points between them the vehicle is traveling;
the angles between leg segments of the upcoming predefined intersection; and
, speed limits.
