Taxicabs are a popular form of public transport in the compact sovereign city-state of Singapore, with fares considered relatively low compared to those in most cities in developed countries. As of December 2014, the total taxi fleet in Singapore was 28,736 taxis, operated by 6 taxi companies and 178 independent drivers. Taxis may be flagged down at any time of the day along any public road outside of the Central Business District (CBD). However, increased usage of Uber and Grab has resulted in a decrease in the usage of taxis.
