Patent US10332401

a) a plurality of cellular-assisted and location-indicative vehicle units carried by a different one of a plurality of vehicles;

b) one or more forwardly directed optical sensors mounted on a same vehicle which are configured to capture road-related images;

c) an image processing unit configured to analyze said captured roadrelated images in real time and to determine, based on said analyzed images, whether the vehicle on which said one or more optical sensors are mounted is to be considered as a running vehicle that is spaced from a traffic light or a traffic sign by a distance shorter than a threshold safe braking distance and that is liable to endanger other vehicles;

d) an alert signal generating unit responsive to the determination of said image processing unit as a running vehicle, for generating a collision avoiding alert signal; and

e) a remote server adapted to receive each of said alert signals and location data of each of said vehicle units, said server comprising a database in which map data representative of a physical layout of a plurality of inspected areas is stored,

wherein said server is operable to process the map data and the received location data of vehicle units for a given inspected area and to determine, for each of the vehicles located within said given inspected area, an instantaneous distance between the vehicle and the traffic light or traffic sign and an instantaneous vehicular speed, and a decision as to whether it is separated from said running vehicle by less than a collision-liable distance,

wherein said server is operable to transmit an additional alert signal, based on the processed map data and location data, to the vehicles found to be separated from said running vehicle by less than a collision liable distance, to indicate to each driver thereof that a braking force must be urgently applied or that any other evasive action must be taken.
