Abstract
A system for increasing awareness of a driver to traffic-signs on the road is provided herein. The system includes: a sensor attached to a vehicle and configured to determine a type of one or more traffic-signs that are present in a scene containing the vehicle, wherein at least some of the traffic-signs are time-variant traffic-signs which present time-variant visual indicators; and a controller configured to: monitor and analyze, in real time: relative metrics indicative of one or more spatial relations between the vehicle and the one or more detected traffic-signs; and temporal data associated with the time-variant visual indicators of the time-variant traffic-signs; apply one or more decision functions to at least two of: the detected one or more traffic-signs and to the monitored relative metrics, and the temporal data associated with the time-variant visual indicators, so as invoke an action selected from a predefined set of actions.

16. A system comprising:
-
a gated sensor attached to a vehicle and configured to receive pulsed and/or modulated signals from a scene, and determine a type of one or more traffic-signs that are present in a scene containing the vehicle, wherein at least some of the traffic-signs are time-variant traffic-signs which present time-variant visual indicators; and a controller configured to; synchronize the gated sensor with said reflected pulsed and/or modulated signals; monitor and analyze, in real time; relative metrics indicative of one or more spatial relations between the vehicle and the one or more detected traffic-signs; and temporal data associated with the time-variant visual indicators of the time-variant traffic-signs; apply one or more decision functions to at least two of;
the detected one or more traffic-signs and to the monitored relative metrics, and the temporal data associated with the time-variant visual indicators, so as invoke an action selected from a predefined set of actions. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method comprising:
-
receiving, via a gated sensor, pulsed and/or modulated signals from a scene; determining, from a vehicle, a type of one or more traffic-signs that are present in a scene containing the vehicle, wherein at least some of the traffic-signs are time-variant traffic-signs which present time-variant visual indicators; synchronizing the gated sensor with said reflected pulsed and/or modulated signals monitoring and analyzing, in real time; relative metrics indicative of one or more spatial relations between the vehicle and the one or more detected traffic-signs; and temporal data associated with the time-variant visual indicators of the time-variant traffic-signs; and applying one or more decision functions to at least two of;
the detected one or more traffic-signs and to the monitored relative metrics, and the temporal data associated with the time-variant visual indicators, so as invoke an action selected from a predefined set of actions.
