The water transportation has diminished its role due to the widespread development of land transport network that can be obviously seen in Figure 2. Prior to present the water transportation in Bangkok, it is best perhaps to highlight the current situation of the public transportation systems in Bangkok. Presently, Bangkokians are able to commute in the city by various public transport modes. A variety choice of traveling either by land or water transport is accessible due to the geographical advantages of the Chao Phraya River that plays a roles main river of the Bangkok. Land transit modes are comprised of rail, bus and para -transit systems both conventional and unconventional modes. The most recent and modern transit in Bangkok is the rail transit which includes both underground (subway) and elevated rail systems. While the current city’s major workhorse transit mode, the bus transit is composed with airconditioned and non-air-conditioned bus services. In addition, there are minibuses running around the city to provide supplementary services. In Bangkok, apart from these typical transit modes of rail and bus, commuters can also commute by the more personalized para-transit system which include the typical para-transit of taxis and a unique 3wheeled taxi locally known as “tuk-tuk” as well as the informal or unconventional para-transit modes of hired-motorcycles or motorcycletaxis and a passenger van or van transit.
