Detailed aspects of MfS
Improve conditions for pedestrians and cyclists by:
•
•
Reducing the dominance of motor traffic
Improving the street’s sense of place
Detailed aspects of MfS
To reduce the dominance of motor traffic while
maintaining a sense of place, make the street
self-calming by, for example:
•
•
•
Reducing sightlines
Narrowing the carriageway
Reducing signing which gives indications
of vehicle priority
Detailed aspects of MfS
Improve the street’s sense of place by, for
example:
•
•
•
Reducing the dominance of motor traffic
Encouraging increased pedestrian activity
Reducing unnecessary clutter

Local Transport Note 1/11
• Published October 2011
• Provides guidance on designing
shared space to meet the needs
of all
• Shared space is a design
approach that seeks to change
the way that streets operate
• Low speeds required for street
to be fully shared
Shared space is defined as…
A street or place designed to
improve pedestrian
movement and comfort by
reducing the dominance of
motor vehicles and enabling
users to share the space
rather than follow the clearly
defined rules implied by
more conventional designs.
Enhancing the Place function
Shared space is
best considered
as a design
approach which
emphasises the
place function of a
street.
Sharing requires low speeds
Low vehicle speeds have more influence on
encouraging sharing than any other aspect of
street design.
Low vehicle speeds can be encouraged by:
• making the street look and feel different;
• creating ambiguity for drivers; and
• making it physically difficult to drive through quickly.
Vision, Purpose, Action
Traffic Signs Policy Paper
• Published October 2011
• The most significant traffic
signs policy review in 40
years
• One of its key aims is to
reduce signing on the road
network
• The Action Plan says we
will provide guidance on
auditing signs
Example - Hierarchy of Give Way signing
Diag. 1003
1 - 1003
2 - 1003 +1023
Diag. 1023
Diag. 502
3 - 1003 +1023 + 502
