A method for calculating and comparing evaluation indices for a signal system of an intersection includes: a traffic statistical information generation step of receiving image information in real time through cameras to derive traffic object information including traffic volume for each driving direction and traffic volume for each lane on a corresponding road at a preset first cycle, and to generate traffic statistical information including the traffic object information and intersection environment information; a digital twin generation step of inputting the traffic statistical information to a simulator, and implementing a traffic situation of the intersection as a graphical digital twin; and a composite congestion index derivation step of deriving a composite congestion index from each of an actual digital twin and a virtual digital twin, in which the evaluation indices are derived based on a congestion time of a predetermined number of vehicles at the corresponding intersection.

Method and system for calculating and comparing evaluation indices for signal system of intersection

The present invention relates to an object region detection method, an object region detection apparatus, and a non-transitory computer-readable medium thereof, and more particularly, to an object region detection method, an object region detection apparatus, and a non-transitory computer-readable medium thereof, capable of further accelerating analysis of object recognition and tracking by preliminarily detecting an object region based on a parameter value obtained from an image decoding process and referring to the detected object region for image analysis.
