Service 178 is a supplementary inter-town route serving between the housing estates of Woodlands, Bukit Panjang, Bukit Batok, Jurong East and Boon Lay. Much of its route plies through industrial areas (such as those around Woodlands Road, Corporation Road and International Business Park), hence demand is strongly skewed towards peak hours.
