Adverse 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 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 why they have been deemed as least appropriate for introduction in city centres in the previous table.
