SINGAPORE: The Land Transport Authority (LTA) said on Saturday (Apr 18) it is investigating technical issues that were again causing inaccurate bus timings and long wait times to be displayed at bus stops and on transport apps.<\/p>\n
The latest issues, affecting the Expected Time of Arrival (ETA) system for buses, came months after a similar incident earlier this year.<\/p>\n
\u201cBus operations are not affected and all services continue to operate at their usual frequencies,\u201d said LTA in a Facebook post on Saturday.<\/p>\n
\u201cOur engineers and ETA system contractors are working to rectify the issue as soon as possible. We apologise for the inconvenience caused.\u201d<\/p>\n
In January this year, LTA reset its ETA system after technical issues prevented buses from transmitting location data to a central server, causing inaccurate timings and long wait times to be displayed at electronic displays at bus stops and interchanges, as well as apps like MyTransport.SG, CityMapper and Google.<\/p>\n
LTA had said that its engineers and the ETA system contractor identified a “memory cache build-up” in on-board systems, which affected around half of the bus fleet across all operators.\u00a0<\/p>\n
Technicians were required to physically service the affected on-board devices, involving the clearing of memory caches and manually updating the firmware for the transmitters.<\/p>\n
The issue, first detected on Jan 10, was fully restored more than a month later on Feb 12.<\/p>\n
Acting Transport Minister Jeffrey Siow told parliament last month that financial penalties would be imposed on a third-party vendor over technical issues.<\/p>\n
CNA has contacted LTA for more information.<\/p>\n<\/div>\n
