Traffic information providing method and system therefor

A traffic information providing system comprising:

• a communication interface;
• a memory in which a computer program is loaded;
• and
• at least one processor on which the computer program is executed,
• wherein
• the computer program includes instructions for performing operations of:
• inputting previously-generated multiple traffic pattern data and real-time traffic information into a traffic prediction model;
• outputting an error at a first time point for each of the previously-generated multiple traffic pattern data;
• and generating traffic information from a departure point to a destination using first traffic pattern data having a minimum error among the previously-generated multiple traffic pattern data, and
• each of the previously-generated multiple traffic pattern data is a combination of pattern speeds per link, which is a minimum unit of a road.

A computer-readable recording medium storing a computer program that, when executed in conjunction with a computing device, causes the computing device to:

• input previously-generated multiple traffic pattern data and real-time traffic information into a traffic prediction model;
• output an error at a first time point for each of the previously-generated multiple traffic pattern data;
• and generate traffic information from a departure point to a destination using first traffic pattern data having a minimum error among the previously-generated multiple traffic pattern data,
• wherein each of the previously-generated multiple traffic pattern data is a combination of pattern speeds per link, which is a minimum unit of a road.
