Contribution to alleviation of key problems
Appropriate contexts All of the implemented examples of guided bus systems have been introduced
along radial ccorridors within cities. In some cases they have been on-street,
eg in Leeds, and in other cases they have been off-street for at least
part of their route, eg Adelaide and Ipswich. In most cases relatively
short sections of guideway are provided to enable buses to avoid key congestion
hotspots; the Adelaide busway differs from these in that it comprises
a more or less continuous guideway, stretching 12km from the suburbs to
the edge of the city centre. For these reasons, the following table is
a little difficult to complete for guided bus systems and we urge the
reader to consider these aspects when interpreting the table. Appropriate area-types
Advers side-effects The main adverse side-effect is that the guideway can represent a barrier to movement. That is, the kerbs may be of such a height as to make it difficult for pedestrians– impossible for some – to cross the guideway and prevent vehicles from crossing the guideway (this latter aspect is also one of the advantages of guided bus systems as it avoids unauthorised vehicles obstructing the guideway). Hence, guided bus systems are a little at odds with the pursuit of a barrier-free environment. This is a major reason why they have not been introduced in city centres and is the reason why they have been deemed as least appropriate to being introduced in the city centre in the previous table.
