Under the scheme, passengers will travel free of charge on 134 bus routes from July 1.
The city's Public Transport Management Centre has restored road markings at 1,572 bus stops, removed disused shelters and upgraded the Sai Gon Bus Station with modern facilities, including new public toilets.
Bus stop bays have been painted with reflective green markings, while older shelters are being replaced and covered walkways added at key bus-metro interchanges.
The city also plans to build four modular multi-storey car parks at major bus terminals and study the development of six to eight smart parking facilities near metro stations, parks and other high-demand locations.
On the digital front, an electronic ticketing system has been rolled out across 135 bus routes, with card readers installed on more than 1,980 buses. The network has also been integrated with all 14 stations on Metro Line 1.
The MultiGo mobile application allows passengers to search routes, track bus arrivals, receive service updates and make electronic payments. More than 17,500 students have registered through the app.
Passengers can travel free without identity verification from July 1 to Sept. 30. From Oct. 1, free travel will require verification through a citizen ID card, VNeID or other approved electronic payment methods.
The city currently operates 180 bus routes with a fleet of 2,432 buses, nearly 68 per cent of which run on electricity or compressed natural gas (CNG).
Officials aim to convert all inner-city buses to electric or other environmentally friendly vehicles by January 2027, with the entire fleet, including interprovincial buses, expected to be fully electric by 2029.
