Introduction to Roundabout Design

Overview:

A 2-day module designed to provide an understanding of the principles and practice of designing roundabouts. This module is aimed at a broad range of professionals who are involved in designing or assessing the adequacy of junctions. The course consists of informal short lectures, practical workshop and discussion sessions, case studies and examples.

Aims and Objectives:

To assist delegates to understand the issues involved in designing and
constructing roundabouts or carrying out improvements
To provide delegates with the knowledge, skills and understanding to carry out
their professional roles
To provide the opportunity for delegates to network and discuss local roundabout
design process
To provide advice to delegates on their own projects and improve their design
and implementation skills

Topics Covered:

Types of roundabout and principles of roundabout design
Delegates will:
Examine the different types of roundabout, their common features and principles
of operation
Geometric design of roundabouts including workshop
Delegates will:
Understand the importance of approach alignment, entry path curvature (deflection) and entry angle requirements
Construct and measure entry path curvatures and entry angles for a roundabout design
Examine the use of build-outs and overrun areas to improve entry path curvature
Re-design the roundabout to improve entry path curvature
Identify and discuss the issues raised
Visibility, signs, road markings and landscaping
Delegates will:
Examine visibility standards for roundabouts discuss their importance
Examine a range of other detailed design factors such as road markings, signing and landscaping
Undertake an audit of a scheme
Identify and discuss the issues raised
Design evaluation workshop
Delegates will:
Evaluate the design of a common type of roundabout
Analyse and discuss the issues raised
Designing for pedestrians and cyclists
Delegates will:
Investigate the provision of facilities for pedestrians and cyclists
Design pedestrian and cycling facilities at a roundabout
Analyse and discuss the issues raised
Circulatory road markings
Delegates will:
Examine the different marking systems available
Design a circulatory marking system
Analyse and discuss the issues raised
Segregated left turn slip roads
Delegates will:
Examine the design principles for segregated left turn slips
Design a segregated left turn slip
Analyse and discuss the issues raised
Compact roundabouts
Examine the design principles for compact roundabouts
Design a segregated left turn slip
Analyse and discuss the issues raised
Vertical geometry at roundabouts
Delegates will:
Examine the methods of designing the vertical geometry
Capacity issues including ARCADY 6
Delegates will:
Understand the principles of capacity design for roundabouts and mini-
roundabouts
Measure the geometry necessary to provide the required information for a
capacity assessment
Observe a demonstration of a capacity calculation using ARCADY 6
Assess and understand how to interpret a typical output from ARCADY 6
Identify the key capacity modelling issues
Road safety issues
Delegates will:
Examine the road safety records of roundabouts and aspects of design that affect this
Undertake a road safety audit of a roundabout design
Identify and discuss the issues raised

Certification:

Delegates completing this course will receive a CPD certificate of attendance, recognised by both the IHE and CIHT.
