The claim, plainly

The Gyeongbu Expressway cut travel time between Seoul and Busan from 15 hours by train to 4 hours by road, carrying 3.7 million vehicles in its first year.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The claim bundles three specific factual assertions regarding the Gyeongbu Expressway. Two legs are accurate, but one is factually misattributed: (1) The ~15-hour pre-expressway travel time was for the old unpaved road route (or the original 1905 railway opening), not the pre-highway train system of the late 1960s, which ran express trains in 4 hours 45 minutes to 6 hours 10 minutes (and ordinary trains in 10 to 12 hours); (2) Driving time on the new expressway was indeed cut to approximately 4 to 4.5 hours upon its July 1970 opening; and (3) Official Korea Expressway Corporation records confirm approximately 3.6 million to 3.7 million vehicles used the expressway during its first year of operation.

Korea Expressway Corporation and MOLIT historical records show that the 15-hour journey prior to 1970 was via existing national roads, whereas 1960s express trains (Jaegeon-ho, Maengho-ho, Gwangwang-ho) took 4.75 to 6.2 hours.
Post-opening transit time by road on the full 428 km expressway was officially reduced to 4 to 4.5 hours following its July 7, 1970 completion.
Official toll and traffic statistics recorded total first-year (1970) traffic volume on the Gyeongbu Expressway at approximately 3.6 to 3.7 million vehicles.
