Abstract:
The trolley bus is a mode of transport situated between the diesel bus and the light rail in terms of capital layout. As a result the trolley bus offers relatively lower limited costs compared to the diesel bus. However, this advantage is not fully utilised. In most cities where it is used the trolley bus does not have the advantage of restricted lanes and uses ordinary streets where it is held up by traffic jams. In addition the trolley bus and the diesel bus routes follow the same routes in many cities, with the result that the overhead lines and infrastructure have a lower utilisation. The ideal role of trolley buses would probably be where a high level of transport coordination exists - i.e.: - trolley and diesel routes should not overlap; - transfer facilities between routes must be sufficient; - timetables should be integrated; - combined fare systems must be offered. Because such circumstances do not exist in South Africa, the role of trolley buses has to be considered against a less favourable background. As a result a limited approach was followed. The aim of the study is to investigate the following aspects: - the role of the trolley bus in the development of a better image of public transport and attract passengers; - the anti-trolley bus arguments that were raised to justify its withdrawal; - the potential role of the trolley bus in third world cities; - the economic features of the trolley buses in South African circumstances.
