Any improvements to
the parking and access facilities are likely to change the number
of visitors. In this instance, limits could not be set immediately
but would be determined from the results of surveillance conducted
over the first 5 years of the new regime.
1. The total annual
number of visitors, or a representative sample, for the whole, or
part, of the site. (This can be used to measure trends.) Until the
implications of any possible changes are established by
surveillance, a lower limit should be set at the annual number of
visitors indicated in the last survey. The upper limit would be the
level at which the quality of visitors' experience is diminished by
overcrowding. This could be measured by
questionnaires.
2. The number of
educational groups. A lower limit should be set at the current
level.
3. Level of
satisfaction measured formally by, for example, structured
questionnaires or visitor surveys.
4. The number of
complaints or compliments.
