Around the world

Historically, the types and features of buses have developed according to local needs. Buses were fitted with technology appropriate to the local climate or passenger needs, such as air conditioning in Asia, or cycle mounts on North American buses. The bus types in use around the world where there was little mass production were often sourced secondhand from other countries, such as the Malta bus, and buses in use in Africa. Other countries such as Cuba required novel solutions to import restrictions, with the creation of the "camellos" (camel bus), a specially manufactured trailer bus.

After the Second World War, manufacturers in Europe and the Far East, such as Mercedes-Benz buses and Mitsubishi Fuso expanded into other continents influencing the use of buses previously served by local types. Use of buses around the world has also been influenced by colonial associations or political alliances between countries. Several of the Commonwealth nations followed the British lead and sourced buses from British manufacturers, leading to a prevalence of double-decker buses. Several Eastern Bloc countries adopted trolleybus systems, and their manufacturers such as Trolza exported trolleybuses to other friendly states. In the 1930s, Italy designed the world's only triple decker bus for the busy route between Rome and Tivoli that could carry eighty-eight passengers. It was unique not only in being a triple decker but having a separate smoking compartment on the third level.

The buses to be found in countries around the world often reflect the quality of the local road network, with high-floor resilient truck-based designs prevalent in several less developed countries where buses are subject to tough operating conditions. Population density also has a major impact, where dense urbanisation such as in Japan and the far east has led to the adoption of high capacity long multi-axle buses, often double-deckers while South America and China are implementing large numbers of articulated buses for bus rapid transit schemes.
