Service 139 is a trunk route connecting the residential areas of Toa Payoh, St. Michael’s, Boon Keng and Bukit Merah with connections to the city areas of River Valley, Dhoby Ghaut, Little India and Farrer Park. Offering various unique route connections, demand is largely moderate throughout the day. Double-deckers were first added to the fleet in 2011.
The route receives considerable demand between Whampoa and Toa Payoh, as residents of St. Michael’s commute to nearby Toa Payoh Town Centre. The sector has been enhanced with a supplementary bus service, Service 139M, from 14 Sep 2014.
MAVIS App Trial
In January 2019, the Land Transport Authority (LTA) launched a six-month Assistive Passenger Information System (APIS) trial for commuters with special needs using an app called MAVIS, short for Mobility Assistance for the Visually Impaired and Special users.
Under the initial trial, 3 buses were equipped with APIS and were deployed on Service 139 serving Enabling Village till end-April 2019, and thereafter redeployed to Service 141 serving Singapore Association Of The Visually Handicapped (SAVH).
During the Committee of Supply Debate 2020, it was announced that the trial would be expanded for 3 years to cover all buses deployed on Services 139 & 141, beginning from Q4 2020.
