Method for calculating expected vehicle arrival time using real-time traffic information, traffic signal control method, and system for applying same

Disclosed is a method for calculating an expected vehicle arrival time using real-time traffic information, a traffic signal control method, and a system for applying the same. A device for calculating an expected arrival time of a target vehicle to a destination using real-time traffic information comprises: a traffic information collection unit for collecting real-time traffic information corresponding to the target vehicle; a travel path analysis unit for classifying intersections and links on a travel path by analyzing the travel path from a current location of the target vehicle to the destination; a link travel time calculation unit for calculating a link travel time using the real-time traffic information corresponding to the intersections and the links classified through the travel path analysis unit; and an adding unit for calculating the expected arrival time by adding the link travel times for the links on the travel path.
