Transportation

River and canals network

An elaborate network of canals known as khlongs gave Bangkok the nickname "Venice of the East" at a time when most transportation was by boat. Today, nearly all of the canals have been filled in and converted into streets. While many khlongs still exist with people living along them and markets often being operated along the banks, most are severely polluted.[20] A notable khlong market is the floating market in Taling Chan district. Through downtown Bangkok runs the Khlong Saen Saeb, which has a canal boat service. The wide river Chao Phraya, flowing through the city, has several cross-river ferries and the Chao Phraya Express Boat with as many as thirty stops along the both banks extending as far as the northern suburb of Nonthaburi.

Roads
Several elevated highways, newly rebuilt intersections, and many partially finished road and rail projects dot the landscape around greater Bangkok, but have done little to overcome the notorious traffic jams on Bangkok's surface roads as private vehicle usage continues to outstrip infrastructure development.

Due to a large number of traffic jams in Bangkok, the elevated highway (Thai: ???????, RTGS: thang duan, "express way"), linking most road networks in Bangkok together, is another choice for the rush. However, tax is to be paid for utilizing the highway depending on size of the vehicle. This highway also leads to some outskirts of Bangkok including Suvarnabhumi International Airport.

Inner-City Buses
A regular bus service is provided by the Bangkok Mass Transit Authority (BMTA) and it operates throughout Bangkok as well as to adjoining provinces around the clock on certain routes. Public buses are plentiful and cheap, with a minimum fare of 7 baht to most destinations within metropolitan Bangkok. Air-conditioned buses have minimum and maximum fares of 11 and 24 baht, respectively. Air-conditioned micro-buses charge a flat fare of 25 baht all routes. A bus route map is available at bookshops.
