The Stage Bus Service Transformation (SBST) programme (Malay: Program Transformasi Bas Berhenti-Henti), commonly branded as BAS.MY (formerly known as myBAS, an abbreviation for Malaysia Bas Awam Sepadu), is a government initiative launched by the Ministry of Transport of Malaysia to enhance public bus networks in key state capitals and urban areas outside the Klang Valley. The programme is regulated by the Land Public Transport Agency (APAD) in Peninsular Malaysia, and the Commercial Vehicle Licensing Board (LPKP) in Sabah and Sarawak.
According to the SPAD 2017 Annual Report, the SBST programme implements a gross-cost contracting model designed to improve the reliability of stage bus services. The initiative is built upon four main concepts: network planning, gross-cost contracts, cashless payments, and performance monitoring. Under this framework, routes are strategically designed based on established network planning principles rather than individual operator preferences.
Bus operators are paid based on vehicle kilometers traveled under an eight-year contract, while the government, through the regulating agency, absorbs the operational risk, covers operating costs, and collects all farebox revenue. To enhance passenger convenience, the programme implements an electronic ticket payment system. Furthermore, strict performance monitoring is enforced; buses are equipped with real-time GPS tracking that feeds data directly into a central Command and Control Centre, and operators face financial penalties if they fail to meet stringent service Key Performance Indicators (KPIs).
The Stage Bus Service Transformation programme was first announced during the tabling of the 2015 Budget in October 2014. The initiative aimed for gradual implementation in Kangar (Perlis), Seremban (Negeri Sembilan), Ipoh (Perak), and Kuala Terengganu (Terengganu).
The myBAS service commenced operations in Kangar on 1 August 2015, initially covering 337 km across six trunk and four feeder routes. This was followed by Seremban on 15 November 2015, which was expanded in January 2016 to cover 656 km with a fleet of 110 buses operating 22 routes. Ipoh saw its first phase launched on 1 June 2016, followed by a second phase in September 2016. The Ipoh network was subsequently revamped on 15 March 2018 to cover 367 km with 16 routes integrated at Medan Kidd and Terminal Amanjaya. Operations in Kuala Terengganu began on 1 March 2018. Notably, Kuala Terengganu and Johor Bahru were designated as the first cities under the scheme to introduce electric buses into their fleets.
The scheme was later expanded to other major cities. Johor Bahru launched its myBAS service on 31 March 2022. Subsequently, Melaka introduced its SBST service on 1 May 2024. These were the first services to implement contactless card payments via Visa and Mastercard, as well as the My50 unlimited bus pass for Malaysian citizens.
In 2024, Transport Minister Anthony Loke announced a comprehensive revamp of the SBST programme, rebranding it as BAS.MY. This rebranding involved a transition from the original blue-and-white livery (or yellow-green-white in Johor Bahru) to a standardized pink livery. The revamp also introduced digital fare payment methods via QR codes, alongside the implementation of the My50 unlimited pass and free travel passes for students, the elderly, and persons with disabilities (OKU).
Following the rebranding, the scheme was expanded to further cities in 2025:
Public bus networks operating under the Stage Bus Service Transformation programme were established in the following cities:
