Design Guidance
•
NRA DMRB
–
–
–
•
Traffic Management Guidelines
–
•
Junction design, VRU facilities, traffic calming
NTA National Cycle Manual
–
•
Road link & junction design
Sightlines
TD 41-42 revised in 2011 – Now includes design standards for local and
regional roads
Cycle facilities
DMURS

Design Manual for Urban Roads and Streets
Published 2013
Replaces DMRB in urban areas

DMURS
•
Design Manual for Urban Roads & Streets
–
–
–
Jointly Published by DTTAS & DoECLG in March 2013
For use in urban areas – cities, towns & villages
Applies to ALL roads & streets in urban areas except:
• Motorways
• In exceptional circumstances, certain roads & streets with the written consent of a
sanctioning body (NRA, NTA, DTTAS)
–
•
Use of the Manual is mandatory, and it supercedes the DMRB in urban areas
Purpose
–
Fill a policy gap
• Emphasis in road design standards on catering for vehicular traffic
• DMRB has been used as a default standard
–
Provide practical design measures to implement Government Policy e.g.
• Smarter Travel (2009)
• Sustainable Residential Development in Urban Areas (2009)
• Draft Planning Guidelines: Local Area Plans (2012)

DMURS
•
Need for DMURS
– Car dependence is now built-in to urban areas as the norm
– Application of DMRB - prioritisation of vehicular traffic over other modes
–
Proliferation of ‘Distributor’ type roads:
•
•
•
•
•
Almost ‘free-flow’ conditions
Wide, open roads
No active frontage
Accesses minimised
No parking
– Creates a hostile environment for VRU’s:
•
•
•
•
•
Promotes faster, inappropriate speeds
Severs communities
Reduces access to public transport
Lack of surveillance
Inhospitable crossing facilities

DMURS
•
What DMURS Promotes:
–
A balanced approach to street design
• Recognise that roads/streets have many functions, and balance function and context
–

Better Connected Communities
Conventional Network

DMURS Network
 Dead ends
 Connected Streets
 Higher Speed & Volume External Roads
 Traffic Calmed Streets
 Larger Junctions
 Smaller Junctions
7
DMURS

Self-Regulating & Liveable Streets:
 Speed based on a visual/psychological
interpretation of the street
 Regulation plays a secondary role

Place Making & Attractive Streets
 Example of a street in Youghal, Before
& after

DMURS
•
Application of DMURS
–
Promotes a multidisciplinary approach to street design
–
Offers guidance for all stages of development, from plan preparation to detailed
design
–
Contains a range of measures & guidance for Architects, Engineers, Planners,
Landscape Architects etc.
–
Manual includes a range of ‘hard’ & ‘soft’ measures to create self-regulating
streets, including:
•
•
•
•
•
•
•
•
•
Building heights & street widths
Hard & soft landscaping
Active street edges
Signage & road markings
Street furniture
Materials & finishes
Reduced horizontal & vertical alignment standards
Reduced stopping sight distances & visibility envelopes
Reduced corner radii & junction geometry
NTA Funded Schemes
• NTA Sustainable Transport Measures Grants (STMG)
• Annual funding to improve VRU facilities and to encourage use of
sustainable travel modes.
• Wide range of schemes completed including:
–
–
–
–
–
Swans Junction (Naas)
Johnstown roundabout upgrade
Captains Hill junction upgrade (Leixlip)
Fortbarrington Road junction (Athy)
Various footpath improvement schemes (e.g. Rathangan, Ardclough,
Prosperous, Athy, Caragh, Athgarvan, Castledermot)
• Approx. 1.4 million secured for 2015, examples of schemes include:
–
–
–
–
