IN THIS PAPER, THROUGH A CASE STUDY ON COMMUTING TRIPS BY FACTORY WORKERS IN THE NORTHERN CORRIDOR OF SUBURBAN BANGKOK, COMMUTING TRIPS' CHARACTERISTICS ARE ANALYZED. THE RESULTS SHOW THAT THE LENGTH OF TRIP HAS BECOME LONG, MAINLY DUE TO IMBALANCED DEVELOPMENTS, THAT THE MODAL SHIFT TO PRIVATE ONES ARE OBSERVED DUE TO INCONVENIENCE OF BUSES, AND THAT HIGHWAY DESIGN DISREGARDS LOCAL TRAFFIC AND ARISES UNNECESSARILY LONG DETOUR TRIPS AS WELL AS INCONVENIENCE OF PEDESTRIANS AND CYCLISTS. THOSE POINTED ABOVE SHOULD BE CONSIDERED IN THE FUTURE PLANNINGS.
