The British colonial government gradually abolished rickshaws from the late 1920s in the interests of safety, especially with the rise in motor traffic.9 At its height in the early 1920s, there were nearly 30,000 licensed rickshaws in Singapore; however, this number had dwindled to 3,693 by 1940.10 After World War II, trishaws replaced the rickshaws, particularly after the latter was banned in 1947 on humanitarian grounds.
