Bangkok has 9.7 million automobiles and motorbikes, a number the government says is eight times more than can be properly accommodated on existing roads. And those numbers are increasing by 700 additional cars and 400 motorbikes every day. Charoen Krung Road, the first road to be built by Western techniques, was completed in 1864. Since then, the road network has expanded to accommodate the sprawling city's needs. Besides roads, Bangkok is served by several other transport systems. Bangkok's canals and ferries historically served as a major mode of transport, but they have long since been eclipsed by land traffic. A complex elevated expressway network helps bring traffic into and out of the city centre, but Bangkok's rapid growth has put a large strain on infrastructure. By the late-1970s, Bangkok became known as "the city of traffic disaster". Although rail transport was introduced in 1893 and electric trams served the city from 1894 to 1968, it was only in 1999 that Bangkok's first rapid transit system began operation. Older public transport systems include an extensive bus network and boat services which still operate on the Chao Phraya and two canals. Taxis appear in the form of cars, motorcycles, and tuk-tuks.

Bangkok Bus Line 8 is a bus route in Bangkok, Thailand. Running between Happy Land Village and Memorial Bridge via Lat Phrao Road, Phahonyothin Road, and Worachak Road. It is operated by many private-joint companies. The Line 8 is notorious for reckless driving and atrocious customer service. Riders filed 345 complaints about the poor services of No. 8 buses in 2015, the highest number of BMTA complaints. On average, Bus Line 8 receives about 20 complaints per month. In informal polling, it has been ranked as the worst bus service in Bangkok.
The Bangkok Elevated Road and Train System, commonly known as the Hopewell Project (โครงการโฮปเวลล์) after main contractor Hopewell Holdings, was a failed project to build an elevated highway and rail line from central Bangkok to Don Mueang International Airport. Construction started in 1990, but was suspended by the first government of Anand Panyarachun in 1992, and was finally halted by legal acrimony in 1997 with only 10-13% complete. The project was cancelled in 1998. Due to its resemblance to standing stones, it was comically nicknamed "Thailand's Stonehenge". As of 2021, idle pillars are still standing.

Don Mueang International Airport is one of two international airports serving the Bangkok Metropolitan Region, the other one being Suvarnabhumi Airport (BKK). Before Suvarnabhumi opened in 2006, Don Mueang was previously known as Bangkok International Airport.

The Mangmoom Card is a planned stored-value card for rapid transit systems in Bangkok. Currently, many commuters carry multiple cards, since the existing Rabbit Card only works on the BTS Skytrain and Bangkok BRT, while the MRT Plus card works on the MRT Blue Line and MRT Purple Line. The card was initially planned to launch in August 2016 but was delayed until at least 2018 as the Office of Transport and Traffic Policy and Planning required more time to integrate the ticketing systems of the different rail networks. In November 2016, Transport Minister Arkhom Termpittayapaisith announced the card would be available to use on the Skytrain, MRT, and Airport Rail Link by the middle of 2017.

The Mass Rapid Transit Master Plan in Bangkok Metropolitan Region or M-Map is the latest version in a series of Thai government plans for the development of an urban rail transit network serving the Greater Bangkok area. It was drafted under the care of the Office of Transport and Traffic Policy and Planning (OTP) of the Ministry of Transport.
