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 and Tollway 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.

The Bangkok tram system (รถรางกรุงเทพ) was a transport system in Bangkok, Thailand. Its first-generation tram network first operated as a horse tram system, and was eventually converted to electric trams in the late nineteenth century.
