Case Study: Singapore Land Transport Authority (LTA)

Turnkey ITCS solution providing common management facilities

In March 2014 Trapeze were awarded the contract in Singapore to implement a new fleet management system for the Singapore Government Agency LTA (Land Transport
Authority).

LTA are undertaking a massive reorganisation of the way public transportation is funded and delivered in Singapore. They are changing from an operator led, revenue based, service delivery model to a model where the operators contract with the LTA to deliver services to a defi ned quality level.

During 2016 two additional operators have been introduced into the Singapore environment. The Trapeze system is at the heart of this reorganisation providing a common bus quality management and monitoring platform across all operators with facilities for LTA to monitor and measure the performance.
