Public buses form a significant part of public transport in Singapore, with over 3.6 million rides taken per day on average as of December 2021. There are 352 scheduled bus services, operated by SBS Transit, SMRT Buses, Tower Transit Singapore and Go-Ahead Singapore. The newest bus operator, Go-Ahead Singapore started operation on 4 September 2016. There are also around 5,800 buses currently in operation as of 2020. History Early history Buses were first introduced into Singapore when the Singapore Traction Company (STC) was established under the Singapore Traction Company Ordinance of 1925 to replace the ill-fated electric tramway with a trolleybus system. The first trolleybuses began operations on 14 August 1926 between Joo Chiat Road and Tanjong Pagar whereas trams were phased out by 1927, with 66 trolleybuses plying on six routes with a mileage of 15” by 30 September that year. The STC later phased in motorbuses in 1929 when seven Dennis G-type buses began plying between Geylang and Finlayson Green before being transferred to serve Seletar. However, the STC faced heavy competition from “mosquito-buses”, a form of informal paratransit operated using privately owned modified Ford Model T vehicles. Reckless driving of such “mosquito-buses” led to the government imposing heavy regulation on them, including having to stop at fixed stops (1923) and speed limits (1927). By 1935, “mosquito-buses” were replaced with more formalised bus services with the former “mosquito-bus” owners establishing what came to be known as the Chinese bus companies; these Chinese-operated buses connected the rural parts of Singapore to the town as opposed to the inner town services of the STC. During the Japanese Occupation during the Second World War, all bus operations were briefly unified under the , fuel shortages then led to some buses being charcoal-powered. 1950s-1960s: Post-war recovery and troubles After the end of the war, the British Military Administration (BMA) was established to oversee the rebuilding of British institutions in its Malayan and Singapore colonies. Under the BMA, the STC slowly returned to normal operations with much of the dilapidated bus fleet replaced with newer motorbuses of the Albion make whereas the Chinese bus companies sought after numerous British makes such as Vulcan and Bedford. On the other hand, trolleybus operations were scaled down with only 50 new Ransomes, Sims & Jefferies-built trolleybuses procured as opposed the original 108 AEC-built trolleybuses from the pre-war period. Trolleybuses were eventually phased out by 1962 and
