Innovation and Best Practice in Performance Measurement and Transport Outcomes

Watch Now:

‘What gets measured gets managed’ (Drucker, 1954). Performance metrics, indicators and benchmarks describe how our road assets (and transport systems) are functioning and operating within the context of the road users’ (and societal) expectations. This enables agencies and authorities to manage investment and resources to address the areas of greatest need.

Austroads first developed National Performance Indicators (NPIs) in 1993 to promote consistency in reporting of road performance across state transport agencies. Over time, however, the uptake of NPIs has diminished due to a misalignment with state agencies’ own performance reporting needs, concurrently with the advent of new datasets and the increased value that these datasets provide.

This webinar, presented by Simon Latham, Scott Benjamin and Robert Kane, explores the current performance reporting practices used nationally and internationally including the type and application of urban road network performance indicators and metrics. The webinar highlights challenges and opportunities related to existing performance indicators and reporting and discusses the recommendations which look to support consistent and commonly agreed performance indicators (revised NPIs) for urban road-based transport performance measurement.

Road Cross-Section Design for Road Stereotypes and a Safe System

Watch Now:

This webinar, presented by Richard Fanning, Noel O’Callaghan and Madeleine Bekavac, is about the guidance on road cross-section design for road stereotypes, which have been developed to assist road managers, planners and designers to achieve improved road safety outcomes through the application of consistent standards along a road corridor.

 

Practitioners will learn about the thirteen midblock road stereotypes that cover rural and urban roads ranging from freeways and motorways to local access roads. Through a number of case studies, presenters will demonstrate the application of the stereotypes for the development of network safety plans that illustrate how to achieve reductions in crash risk along the network.

 

Presenters also outline a range of cross-sections with different attributes that were considered appropriate for each road stereotype and assessed for crash risk using the International Road Assessment Program (iRAP) star ratings, the Australian National Risk Assessment Model (ANRAM) fatal and serious injury (FSI) crash prediction models.

 

A user guide developed to assists practitioners in selecting the most appropriate stereotypes suitable for the needs of their jurisdictions is also discussed.

Pedestrian Planning and Design for Activity Centres

Watch Now:

This webinar, presented by Ann-Marie Head and Jeanette Ward,  focuses on the planning and design considerations that contribute to walkable activity centres - vibrant places where people shop, work, meet, relax and often live. The session also explains where this information can be found in Austroads’ guides.

The webinar covers the following key topics:

  • what data to collect
  • planning/network considerations
  • examples of applying walkable characteristics
  • design considerations
  • types of shared space streets
  • best practice examples.

This session is the fourth in the series of webinars held by Austroads to step practitioners through the updated pedestrian planning and design information.

Austroads’ review of the pedestrian planning and design guidance in the Guide to Traffic Management (AGTM) and Guide to Road Design (AGRD) identified a total of 120 planning and design gaps. Recommended changes to the AGTM were published in April 2020 followed by a series of exceptionally popular webinars.

Recommended changes to the AGRD have been reviewed and approved by the Road Design Task Force and will find their way into the AGRD as part of its update and restructure planned by the Road Safety & Design program in FY20-21.

Transitions Between Steel Beam and Concrete Barriers

Watch Now:

A transition in a safety barrier system is a short section between a more flexible system and a less flexible system to decrease the flexibility gradually along its length. At present there are various transition designs being used by road agencies.

This webinar describes the development, testing and evaluation of a proposed Australasian transition from a strong post public domain W-beam to a concrete barrier.

Presented by Rod Troutbeck, Daniel A. Naish and Jade Hogan.

Road Space Allocation for Pedestrians

Opportunities to Build Capacity in Traffic Management

Watch Now:

An Austroads study of Australian and New Zealand roads capability (AP-R574-18) identified capability/learning gaps amongst graduates and novice practitioners in traffic management. The 2018 study also confirmed that road agencies are experiencing skill shortages and the existing roads workforce will be under threat from rising activity in other sectors.

To address this recognised lack of traffic management knowledge and skills, a series of ‘short and sharp’ learning modules were developed on a range of fundamental traffic management topics.

The learning modules were developed in collaboration with Austroads member agencies and informed by user testing with young practitioners.

Designed for practitioners entering the field and anyone who wishes to increase their knowledge and improve their capabilities in traffic management, the learning modules cover 21 topics and contain supporting quizzes and tutorials. The units include an Introduction to Traffic Management, Traffic Theory, Studies and Analysis, Network Operations Planning and Management, the Safe System Approach and Intelligent Transport Systems.

This webinar discusses the selection of traffic management topics covered in the learning modules and the processes involved in their development and testing. It demonstrates the learning modules and shows how to access them from the Austroads website.

Presented by Paul Bennett and Graham McCabe.

Development of Design Procedures for Lightly Bound Cemented Materials in Flexible Pavements

Watch Now:

The addition of a small amount of cementitious binder to non-standard granular materials may result in a fit for purpose base or subbase at a significantly lower cost than crushed rock complying with standard specifications. Such lightly bound cemented (LBC) materials have particular use in pavement rehabilitation and heavy patching as they are less susceptible to block cracking and crocodile cracking than cemented materials.

The binder content and strength of LBC materials are significantly lower than heavily bound cemented (HBC) materials. Austroads’ recent report, which reviewed the performance of selected Queensland pavements with LBC bases, has shown that it is possible to design and construct a low-strength material with base thickness and subbase support sufficient to limit the extent of the micro cracking development that leads to macro-cracking.

Considering the use and performance of LBC for moderate to heavily trafficked roads, a structural design method was developed for pavements containing LBC materials and HBC materials in the post fatigue cracking phase of life, including:

  • A new elastic characterisation method, applicable to LBC materials and HBC materials in the fatigue cracked state, including methods to vary the design modulus according to the design modulus of the layer supporting the cracked material and the thickness and modulus of the overlying bound materials.
  • Design charts to select LBC base thicknesses to inhibit the development of block cracking and crocodile cracking, with the minimum thickness varying with design traffic loading and the support provided by the layer under the LBC base.

This webinar, presented by Dr Geoff Jameson and Dr James Grenfell, explains the structural design method in detail, including its development and application.

Improved Guidance on Interrupted Traffic Flow Theory

Watch Now:

Austroads has recently completed a project to review and propose improvements to the guidance on interrupted traffic flow theory contained within the Austroads Guide to Traffic Management (AGTM), Part 2 and Part 3. The updates will broaden practitioners’ understanding of interrupted traffic flow theory and enable them to manage congestion on road networks more effectively.

This webinar, presented by Mark Plattz and Emily Plath, will equip practitioners with the knowledge of the existing topics and emerging best practice in the assessment of simple and complex traffic scenarios in an Australasian context.

Presenters outline the work undertaken during the project and detail the proposed changes to Part 2 and Part 3 of the Guide to Traffic Management. The key areas that have been identified for development in AGTM Part 2 and Part 3 include bottlenecks, travel time reliability, roundabout theory, analysis of signalised intersections, active transportation and demand management, multi-modal considerations and traffic flow impacts of heavy vehicles.
