Additional guidance to BV165
Please Note: This is DfT draft clarification of guidance not yet
adopted by ODPM or the Audit Commission.
For the purposes of calculating the BV165 indicator :
=B7 a pedestrian crossing will be defined as a signal-controlled
crossing carrying pedestrians across a highway from one footway to
another footway, irrespective of any intermediate islands or refuges;
=B7 A mid-block crossing of either a single or dual carriageway will
count as one crossing; and
=B7 a four-arm junction with crossings on all arms would count as
four crossings, regardless of whether the arms are single or dual
carriageways.
Audible and tactile signals
To comply with the indicator crossings installed before the revised
indicator came into operation on 1 April 2002 must be fitted with either
audible or tactile indicators. Crossings installed or substantially
refurbished after that date should be counted if they have both tactile
and audible indicators, except where it would be unsafe to install
audible indicators or where local objections have led to their removal.
Tactile surfaces
To comply with the indicator all crossings should be installed or
refurbished with tactile paving and dropped kerbs in accordance with the
Department for Transport's Guidance on the use of tactile paving
surfaces (DTLR 1999). However it is recognised that changes may occur
during the life of a crossing, so that dropped kerbs on older crossings
may still be regarded as compliant with an upstand up to 3mm different
from the dimensions in the guidance.
General
It is not possible for guidance to cover all potential variations in
physical conditions at crossings throughout the country. This is
recognised in the final paragraph of the indicator which states that "*
those crossings counted as meeting the BVPI will have the facilities
appropriate to their local conditions."=20
If physical conditions at a site mean that the guidance listed in the
indicator, is inapplicable; a local authority should make their own
assessment of whether a crossing complies, and record the reasons for
their decision for possible examination by the Audit Commission.=20
However, it is not acceptable for a crossing to be regarded as
compliant in circumstances where other traffic management alterations
could be made to allow the crossing to be fully compliant. For example
if the installation of additional detection to allow an extended
clearance period when traffic is caught within a junction at the end of
the vehicle green would in turn allow installation of audible and/or
tactile indicators in circumstances where otherwise such signals would
not be provided for risk of directing visually-impaired pedestrians to
begin crossing when traffic was still moving.
