Rationalisation of bus services are carried out by the Land Transport Authority (LTA) to optimize service levels offered by Singapore’s public transport network. These efforts include the reduction of operating frequency or operating hours of certain bus services, or the merger and withdrawal of certain bus services that suffer from low demand.
Under the Bus Contracting Model (BCM), the LTA assumes the role of a central planning agency, and decides on bus services to be provided, and the service standards which operators have to meet. As part of this responsibility, public transport connections that are duplicitous or underutilized are rationalised to optimise the usage of resources and cut down on financially unsustainable services.
Historically, large-scale rationalisation of bus services were conducted following the opening of new rail lines to avoid duplication. In modern times, rationalisation of bus services are more restrained and targeted at the most underutilized bus routes.
This article summarises these changes to bus services since the start of 2019, and will be updated with instances of upcoming announced bus service rationalisations where implemented.
