The Land Transport Authority (LTA) announced in a statement on Jan. 22 that the Expected Time of Arrival (ETA) system on the MyTransport.SG app is undergoing restoration works and will be switched back on from Jan. 23 onwards.
The system was met with technical issues that led to inaccurate waiting time estimates, the organisation said in a statement on Wednesday.
It was then reset at 8pm on Jan. 21.
The problems, which were first detected on Jan. 10, caused some commuter touchpoints to display unusually long or incorrect bus arrival times.
Checks by Mothership on MyTransport.SG app early on Jan. 21 showed that wait time estimates at a bus stop were as long as 44 minutes.
Root problem
LTA said that the root cause of the issue has been identified, pointing to a memory cache build-up in the on-board systems of some buses.
This disrupted data transmissions between on-board bus systems and the central ETA processing servers, leading to missing bus arrival timings, the statement added.
About 50 per cent of the bus fleet across all bus operators was affected.
Missing figures expected
While the system will be switched back on on Jan. 23, there can be some expected missing arrival figures while restoration works go through progressive testing and restoration.
"Bus arrival timings will not be fully available or accurate during this period as we progressively restore system performance and complete thorough testing," said LTA.
Works are expected to take approximately four days to be completed.
From Jan. 23, more than 60 per cent of bus arrival timings will be available for commuters at touchpoints such as the electronic passenger information displays at bus stops and interchanges, apps like MyTransport.SG and third-party apps such as CityMapper and Google Maps.
All other bus services will experience missing arrival timings or timings with longer headways, though these should gradually become less common, LTA said.
