commutation แปลว่า

"but there was no city officer to stand forth and ask for it — not even so much as to require frequent trains, low fares, and commutations on that part of the road which ran within the city limits."

"These permit the limited number willing to abandon their automobiles for long hikes to visit some of the most rugged terrain in Southern California. Major resort centers with substantial year-around residence (and much commutation) occur in the western Santa Monica Mountains, the San Bernardino Mountains, and around Idyllwild in the San Jacinto."

"After decades of complaint that cities are exploited by suburban commuters, the American metropolis is experiencing more and more commutation in the other direction. In some metropolitan areas, there is as much commutation out of the city as into it."
