The "notice boards", (2 off 1mx1m frames at the back of the
shelter) are paid for by Adshel. They were part of the DBO contract
with LTA. The left hand noticeboard is for Town council to use and
the right hand is for LTA Transit Link to place the bus
timetable.
Transitlink have commenced the rollout of the timetables island
wide. Approx 50% of the 3000 Adshel sites have noticeboards, this
number and the locations were determined by LTA prior to tender
based on number of services. LTA can be contacted to install more
if deemed required. Contrary to some of the posts, LTA do not pay
Adshel for the display of posters in the noticeboards. Only the
Adpanel 1.8x1.2m display at the end of the shelter is used for
advertising.
Hope this helps.
PS. LTA Road Projects and Maintenance look after all bus shelters
in Singapore and the control of both Adshel ,JCD and other
contractors. The bus operators have no jurastriction or payments to
look after the bus shelters or associated street furniture.
