Annex B: Dropped crossing methodology

· Approach to design options (See glossary below for definitions):

o Option 1 – Can an uncontrolled crossing point (pair of dropped kerbs with tactiles, with gradient not exceeding 1:12 as specified in national guidance and shown in Figure 5B below and standard detail at the end of this document) be delivered? If not;

o Option 2 – Can a reduced depth uncontrolled crossing point be delivered (pair of dropped kerbs with tactiles, with gradient not exceeding 1:12 as specified in national guidance and shown in Figure 5A below and standard detail at the end of this document)? If not;

o Option 3 – Can an uncontrolled raised crossing point with tactiles be delivered (key considerations include height and gradient, drainage, road marking, signage and lighting – the introduction of a 20 mph zone for the City Centre may be required to enable the delivery of raised crossings)? If not;

o Option 4 – Can an uncontrolled crossing point with tactiles be provided using build outs (key considerations include height and gradient, carriageway widths, potential parking issues, drainage, required signage and lighting)? If not;

o Option 5 – Can an uncontrolled crossing point with tactiles be provided by dropping the full width of the footway on both sides (key considerations include height and gradient, potential parking issues, drainage)? If not;

o Option 6 - Can another location nearby accommodate any of the options listed above? If not;

o Option 7 – Can a dropped kerb without tactiles be delivered (not compliant with guidance due to gradient and/or lack of matching dropped kerb opposite for example)?

CROSSING POINTS GLOSSARY (at grade crossings)

Controlled crossings: A facility provided to help people cross a carriageway but where they have priority over motorised traffic.

Types of controlled crossings include:

· Zebra crossings; and

· Signalled controlled crossings.

Uncontrolled crossings: Uncontrolled crossings do not afford pedestrians any particular priority over motorised traffic, although some layouts may result in some drivers deciding to give way. Some pedestrians may decide to assert priority over drivers, but this cannot be relied on.

Types of uncontrolled crossings include:

· Dropped kerb crossings;

· Flat-topped road hump;

· Refuge/central reservation (allowing crossing in two stages on wider roads, generally not applicable to city centre streets);

· Build-out;

· Side road entry treatment;

· Blended junction or continuous footway (level walking surface where drivers cross the footway, which continues across the junction – applicable to side roads).
