SINGAPORE: The system that shows estimated public bus arrival times, which has been faulty since Jan 10, will not be fully restored until early next week.
The new timeline, announced by the Land Transport Authority (LTA) on Tuesday (Jan 27), pushes back the authority’s earlier estimate on Jan 22 that full restoration would take around four days.
In its latest update, LTA said it had resolved the issues for 3,000 buses last week, and the Expected Time of Arrival (ETA) system would be "restored to 85 per cent" by the morning of Jan 28.
The system was first reset on Jan 21, following technical issues that caused long wait times to be displayed.
LTA said on Tuesday that another 1,000 buses will now require "manual firmware updates" in order for the system to be fully restored.
"We will do so over the course of the week, as this process can only take place after service hours. We expect the ETA system to be restored fully by early next week," said LTA.
LTA previously said that its engineers and ETA system contractor had discovered a “memory cache build-up” in the on-board systems, affecting around 50 per cent of the bus fleet across all operators.
It added that technicians would have to physically service the on-board devices.
Commuters were not able to see estimated bus arrival timings on electronic displays at bus stops and interchanges, and on apps like MyTransport.SG, CityMapper and Google during the system reset.
The system was switched back on at the start of passenger service on Jan 23, but bus arrival timings were not fully available or accurate amid ongoing restoration and testing.
CNA spoke to some commuters who experienced unreliable bus arrival information on Jan 23, with some buses arriving 20 minutes earlier than displayed and others arriving much later than expected.
The issue involving missed bus arrival predictions was first detected on Jan 10, LTA previously said, with further inaccuracies subsequently detected over the course of the week.
Buses have continued to operate at their usual frequencies throughout.
