Over the years, Singapore's public bus has become more reliable, connected and integrated with the larger land transport network. LTA's Bus Contracting Model (BCM) was introduced in September 2016 as part of these efforts to improve bus services. Under this model, the government owns the bus assets, infrastructure (including integrated transport hubs) and systems. LTA is responsible for planning bus services.

Bus operators receive payment to run bus routes at service standards set by LTA. This is done through competitive tendering. It raises the reliability of bus services and improves waiting times for commuters. The model also motivates operators to invest in hiring, training and upgrading the bus workforce.

The four bus operators in Singapore are SBS Transit, SMRT Buses, Tower Transit Singapore, and Go-Ahead Singapore. Together, they manage 14 bus packages. The latter two joined the industry after the introduction of the BCM.
