Taking the Highway out of Albany Highway
 
‘There’s no way I’d let my child cycle to school on that road’. That was the general opinion of many parents whose children attend school along Albany Highway.  Although we tend to start most design projects with a brief relating to standards, the Albany Highway project is one of the first corridors in New Zealand to be designed with its end users driving the process – a truly customer focused project.
The existing Albany Highway is a typical two lane highway. Over time the land adjacent has developed to include a business park, university campus and four schools.
 
The challenge for the project was to create a more relevant corridor which provides for all modes and is more productive in terms of the number of people that could use the corridor.
 
So providing infrastructure which supports changing travel behavior became a foundation to scheme development.  The Auckland Transport Community Transport team engaged with the schools and businesses to look at how they travel and measures which would encourage use of alternative modes. This was a huge success in itself – encouraging a 15% reduction in car trips along the corridor.

In terms of cycling infrastructure the message was clear – to get kids on bikes you need to convince parents that it will be safe. A share with care type approach isn’t practical on one of the regions cycle highways and so the concept of Auckland’s first Copenhagen style corridor was born.

The Corridor Management Plan for Albany Highway provides a clear vision for the corridor which added value during the detailed design process. 
 

  • Compromises to design standards – such as reducing lane width to 3.2m were agreed early and documented
  • Intersection treatments were developed which accommodated all users – this got stakeholders on board including cycling advocates
  • Early constructability and maintenance considerations to reduce risk
  • Clarification of the nearside lane as a High Occupancy Vehicle Lane allowed other design components such as bus stops and signs can be developed appropriately




“the proposal looks suitable for just about everyone – from novices or school children to commuter cyclists who may be in more of a hurry. … Cycle Action Auckland is very happy to see these kinds of plans come forward “on their own”. It shows that Auckland Transport and road designers like GHD are increasingly aware of how to provide for cyclists. So even if Albany isn’t your patch, it’s good news for cycling in Auckland.”
Cycle Action Auckland – July 2011

At intersections cyclists have the option to remain off road or rejoin the carriageway
 
Through the detailed design process the team were able to focus on reducing risk and improving the quality of the scheme.

Materials were selected which differentiated between driveways, footpath and cycleway. This reduces street clutter and improves the overall amenity of the corridor.

A tree line was maintained to act as a ‘shadeway’ providing pedestrians and cyclists with a level of comfort in summer.

The initial concept of cycle treatment at intersections was developed to meet safety considerations and provide a smooth transition for users.

The scheme has now gone to the market for construction and it is a credit to Auckland Transport that the integrity of the concept has been maintained through the detailed design process.
The new improved Albany Highway is scheduled to open at the end of 2016 and with it a generation of new cyclists.

REAAA Technical Sub-Committee TC – 2 Pavements

Status Report April 2014

The goal of the pavements technical committee is for member countries to study the improvement of pavement maintenance technologies, including management systems, in order to maintain the road network in a good condition for as long as possible.  The committee shares information on pavement maintenance by summarising and examining the best practices in member countries in terms of management systems, monitoring methods, materials and methods for pavement maintenance and repair work.  Ecological issues associated with pavement maintenance/repair works, including recycling technologies and the use of environmentally-friendly materials, are also relevant.

The committee is made up of members from Australia, Brunei, Indonesia, Japan, Korea, Malayisa, New Zealand, Philippines, Singapore, Taiwan and Thailand.
 
Compendium on Pavement Durability

After the formation of REAAA Technical sub-committee TC-2 (Pavements) in late 2010, the committee members approved the preparation of a Compendium on Pavement Durability in line with its Terms of Reference (TOR) during its first cycle of operation.  This study involved the assessment of effective methods and measures in terms of their life cycle costs (LCC) and environmental impact.
 
The first stage of the study was the preparation of a questionnaire which was sent to all member countries seeking information regarding the types of roads in their region, the most common types of pavements/layers, the typical types of pavement distress encountered, countermeasures to improve them, and an assessment of the effectiveness of the measures taken.  A total of 15 case studies from seven countries were submitted to the Working Group.
 
The main types of pavement distresses identified in terms of the need to maintain a durable pavement were: fatigue cracking, rutting, roughness/faulting and potholes.  The main counter-measures included: the use of new or specific materials; improvements in construction methods; and improvement in quality assurance/control.  As expected, these measures were reported as being successful in most cases.
 
The second stage of the study involved the collation of reports and technical papers describing members’ experience in the management of durability. A total of 11 reports were submitted by five countries.
 
Most of the measures used to manage durability were symptomatic and undertaken in the maintenance stage in response to emerging needs.  However, they can also be taken into account in the planning and design stages of pavement management.  In other words, a well-planned, middle or long term strategy will be the best way to improve pavement durability.
 
The compendium is currently undergoing final review and editing and should be completed by the middle of 2014.

 The Technical sub-committee TC 2 Pavements is also compiling the results from a survey on pavement recycling completed by its member countries.  This topic is one of three themes currently being studied by the PIARC committee TC4.2 Road Pavements.  If the information collected through the survey is informative, REAAA TC 2 will seek to collaborate with PIARC TC4.2 at the XXV World Roads Congress, to be held in Seoul, Korea, on 2-6 November 2015.
 
In terms of the main theme of the pavements committee the working group is hoping to compile a report/compendium on “pavement maintenance practice” by collecting typical maintenance practice in the member countries.  This will commence in May 2014.

NZ Transport Agency 2014/15 Research Programme

In September last year The NZ Transport Agency asked selected transport sector organisations to report to them the key land transport challenges they are facing - and how research can assist to address these challenges. 

The organisations who are nominated as transport decision makers for the purposes of the research programme, namely the Transport Agency, the Ministry of Transport and Local Government NZ, considered the challenges in the formulation of research topics for 2014/15. 

The list of research topics formally approved is now published on the NZ Transport Agency website at http://www.nzta.govt.nz/resources/research/docs/approved-2014-15-research-topic-list.pdf.
 
Further information is available about the Research Programme at http://www.nzta.govt.nz/resources/research/index.html

Advanced Pavement Design ENTR603 at University of Canterbury

Advanced Pavement Design course (ENTR603) covers several important topics for design, maintenance and rehabilitation of both flexible and rigid pavements. The course covers distresses in flexible and rigid pavements (types, reasons, and possible repair), pavement structural condition evaluation using pavement condition data and deflection analysis,  mechanistic-empirical pavement design (AASHTOWare Pavement ME Design) and Austroads M. E. design, concept of preventive maintenance, a preventive maintenance program, maintenance materials, typical treatments, recycling of pavement materials, sustainable pavement design and endurance limit, perpetual pavement, Superpave technology for binders and aggregates  characterisations and mix design, rigid pavement design, and overlay design for both flexible and rigid pavements.  This year, international expert Dr Michael Mamlouk, Professor and Chair of the Civil, Environmental and Sustainable Engineering, Arizona State University, USA, will cover the first three day block of the course. This will be great opportunity to introduce the AASHTO Mechanistic Empirical Pavement Design by one of the North American international expert and to compare this method with the currently adopted  Austroads M.E.  Attached is the course outline and the first block course planner.
 
Further information on the course can be found here Course ENTR603 or at the University's website www.canterbury.ac.nz
