ATC SR&T WG: Visibility of Strategically Important Transportation Data

     Visibility of Strategically Important Transportation Data
1.       Executive Summary
The November 2008 ATC meeting endorsed the Data Action Plan proposed by the Strategic Research
and Technology Working Group (SR&T WG). The Action Plan includes identifying strategically
nationally important transportation data, identifying data gaps and developing minimum metadata
standards for such data.
Consultation in every State and Territory culminated in a national workshop in Sydney (February
2009) that confirmed data needs, the existing data used and data gaps and these are listed in this
paper. The workshop highlighted data visibility as the highest priority for the Data Action Plan.
Previous attempts at establishing national transportation data websites for access and visibility have
floundered due to issues around data custodianship. Having a well targeted website is international
best practice and continues to be the obvious way forward but needs to address issues that
previously prevented similar initiatives from being implemented.
The first step for the improving data visibility is to pilot a website that tests the visibility of meta data
        Acting as a data directory only, not a data warehouse;
        Systematically describing the data and its quality attributes using minimal metadata;
        Linking directly to custodian’s data, where appropriate; and
        Establishing protocols for running the website and ensuring cooperation and commitment of
         data owners, for example, ensuring data ownership and control are not infringed.
The lessons learnt from the pilot will inform recommendations to the November 2009 ATC meeting
for a functional and enduring website and the steps that need to be taken to achieve it. This will
include further development and ongoing maintenance costs and a proposed business process to
support it.
The long-term vision is for a few clicks of a mouse to give access to agreed data vital for evidence-
based policy development by the Commonwealth, States and Territories. It will also facilitate other
important outcomes of the Data Action Plan

2.       Purpose

This paper supports the transportation data recommendations of the Strategic Research and
Technology Working Group to the ATC meeting of 7 May 2009. It identifies:
        Existing nationally important transportation data collections, their purpose and currency;
        Gaps in existing nationally important transportation data;
        A draft set of minimum metadata items;
        Data gaps; and
        A list of priority datasets for which metadata will be collected and made visible via a web-
         based system.
The nationally important transportation data collections, listed in Attachment 1, were developed
following extensive consultation with key transport data owners and users, and finalised following a
workshop of key stakeholders, held in Sydney in February 2009. The list of nationally important
transportation data will help inform identification of strategically important national transportation
data sets and data gaps.
Visibility of metadata is an important first step in improving the accessibility of transportation data.
In this context, visibility means identifying available transportation datasets that are nationally
important and providing metadata statements to assist users in deciding fitness for purpose.
Development of the Strategic Research Agenda will be completed after the May 2009 ATC meeting.
The Agenda will identify strategically important national data priorities, and a set of strategically
important national datasets will be produced to accompany the Strategic Research Agenda Working
Group recommendations for the November 2009 ATC.
This paper:
        Contributes to the requirements of Transportation Data Action Plan’s Action items 1 and 2;
        Prepares the groundwork for undertaking Actions 3, 4, 5 and 6; and
        Proposes the way forward for undertaking Action 7.
The paper also addresses ATC’s direction to develop a common definition for minimum metadata
standards covering transportation data.
The paper does not cover all of the data activities being undertaken by the Strategic Research and
Technology Working Group

3.       Background

3.1      ATC Recommendations

At its meeting of 29 February 2008, The Australian Transport Council (ATC) agreed to accept a new
National Transport Policy Framework (NTPF).

                                                                                                 Page 4
ATC SR&T WG: Visibility of Strategically Important Transportation Data

The Strategic Research and Technology (SR&T) Working Group, chaired by the Tasmanian
Government has the objective:
           “To present a viable model for the advancement of strategic research and
           technology that integrates modes, jurisdictions and technologies to support the
           operation of a single marketplace for transportation.”
Data was identified by the ATC as an issue to be addressed by the SR&T Working Group. The
research undertaken by the SR&T Working Group confirmed that there was no recorded agreement
on what constitutes nationally important transportation data and there was little systematic
coordination. It found that developing a case and strategy for integrating and improving the quality
of transport data was essential and there was a need to develop:
          The quality requirements of national transportation data;
          A governance model for transportation data, within the broader SR&T governance; and
          Data visibility models.
At its meeting of the 7th November 2008, the ATC endorsed the SR&T Working Group’s
recommendations. The recommendations relevant to transportation data were:
        2. ATC AGREES to jurisdictions adopting the ABS Data Quality Framework as the common
           data framework for all strategically important national transportation data.
        3. ATC DIRECTS the Strategic Research and Technology Working Group to develop a
           common definition of the minimum metadata standards for strategically important
           national transportation data for adoption by transportation agencies.
        4. ATC AGREES with the Action Plan for improving transportation data and DIRECTS the
           Strategic Research and Technology Working Group to initiate its implementation.

3.2     Transportation Data Action Plan

A paper supporting the recommendations listed the Transportation Data Action Plan:
        Action 1     Identify strategically important national transportation data.
        Action 2     Identify data gaps and coordinate data collections and other approaches to
                     filling these gaps.
        Action 3     Define classification systems, collection methodologies and standards to be
                     used for strategically important national transportation datasets.
        Action 4     Establish minimum accuracy criteria for strategically important national
                     transportation data.
        Action 5     Establish minimum data currency criteria for strategically important national
                     transportation data.
        Action 6     Improve the institutional environment for managing strategically important
                     national transportation data.
        Action 7     Provide access to strategically important national transportation data via a web-
                     based data gateway.

                                                                                                Page 5

3.3          Process

The process undertaken included:
     (i)         Developing a definition for transportation data of strategic and national importance;
     (ii)        Consultation with transportation data users from a broad spectrum of transportation
                 agencies via interviews and local workshops;
     (iii)       Documentation of the information collected by common themes and preliminary
                 identification of data gaps as per the table in section 5 of this report;
     (iv)        Conduct of a national workshop with broad representation from all sectors to ensure
                   Possible oversights in the initial consultation were overcome;
                   Perspectives from the many important stakeholders were brought to light; and
                   Biases and errors in the documentation, which may reflect the position of asset
                     owners and regulators as compared to the views of users, were addressed.

4.           Nationally important data collections and data needs

4.1          Clusters of Data Needs

In analysing nationally important data needs and collections, data was grouped into six clusters:
            Transportation and the economy;
            Transportation operations and performance – people and freight movement;
            Transportation demand;
            Transportation infrastructure;
            Transportation safety and externalities; and
            Transportation and land use planning.
These clusters proved useful in consultation and during the workshop. While a need may be primary
to a particular cluster, any one need may have some requirements in several clusters. To avoid
duplication and confusion, data needs are generally listed only under their primary cluster.

4.2          Data Needs, Data Collections and Data Gaps

The list of data needs, data collections and data gaps in Attachment 1 are the combined outcome of
the series of stakeholder consultations and the February data workshop. Development of the
strategic research and technology agenda may uncover further data needs and these will need to be
The list will be finalised and forwarded for endorsement to the November 2009 ATC. Compilation of
this list contributes to the delivery of Action items 1 and 2 of the Data Action Plan.

                                                                                                    Page 6
ATC SR&T WG: Visibility of Strategically Important Transportation Data

In the longer term, the emergence of new policy needs may result in new data needs. Periodic
review of the data requirements will need to be undertaken.
Attachment 1 lists the data needs, data collections serving them and data gaps.

5.       Data Visibility Priorities
5.1      Need for Data Visibility

Knowledge of the existence of data is a widely recognized issue for transportation data users and
this is particularly true for some jurisdictional data. There are many reasons including:
        The size of transport agencies and their governance arrangements;
        The production and use of data by academic and commercial organisations;
        The quality of statistical data management practices varying within agencies;
        Lack of recognition of the value of data holdings to potential users outside of the immediate
         business area; and
        Suitability of the form or medium through which the information can be accessed.
Identifying and obtaining information about potentially rich and relevant data sources can be time
consuming and once found other aspects of accessibility often emerge as barriers to obtaining the

There is no single up-to-date national source of information about transportation data available in

The Data Action Plan’s action 7 is to “Provide access to strategically important national data via a
web-based data gateway.” The Transportation Data Report which supplied supporting information
to the November 2008 ATC data recommendations gives background and considers options.

Previous attempts to establish data gateways or data portals have been unsuccessful in part due to
the proposals threatening the ownership of datasets. Success requires a step-wise approach that co-
operatively engages data owners.

The first step to having a web-based data gateway for strategically important national transport data
is to provide visibility to the most valuable available transportation metadata.

In this context, visibility means:
        Being web-based and publicly available;
        Having the features of a data directory;
        Having metadata with the minimum level of description of the data necessary to understand
         what the data represents.; and
        Including contact details of whom to contact and information on how to obtain the data.
The task of developing a system and metadata to populate it for all of the datasets identified in
Attachment 1 is not insignificant . A proof of the concept as a working system is required before a
full system should be developed. For this reason criteria were developed to assist in the selection of
data sets that had priority and would be the first to be recorded.

                                                                                                 Page 7
       ATC SR&T WG: Visibility of Strategically Important Transportation Data

       5.2     Metadata Content

       The minimum metadata required to make Australian transportation data more visible will likely
              Name of survey/collection;
              Data owner/custodian;
              Collection purpose;
              Scope and coverage;
              Description of the dataset;
              Data frequency and currency;
              Access arrangements; and
              Contact details.

       5.3     Criteria for Data Visibility Priorities

       The criteria for choosing priority datasets for visibility:
              Likely to be of high importance for the NTPF;
              Already existing;
              Have identifiable owner(s);
              Have data owner (s) likely to be willing to make the minimal level of metadata visible on a
               website; and
              Have metadata likely to be available (even if the metadata might not yet be described in a
               user-friendly form).

       5.4     Priority Datasets for Visibility

       The following table lists the datasets identified as being of priority for data visibility.

ATC SR&T WG: Visibility of Strategically Important Transportation Data

5.5     Further Work
Between May and November, the SR&T WG will:
       Identify strategic nationally important transportation data sets
       Finalise minimum metadata standards for national important transportation data;
       Develop minimum metadata for the data visibility priority data sets; and
       Establish protocols for running the website and ensuring cooperation and commitment of
        data owners, for example, ensuring data ownership and control are not infringed.
A paper outlining the minimum metadata standards will be produced for the owners of the priority
datasets for visibility and critical stakeholders.
The lessons learnt from the pilot will inform recommendations to the November 2009 ATC meeting
for a functional website and the steps that need to be taken to achieve it.
The long-term vision is for a few clicks of a mouse to give access to jurisdictionally agreed data vital
for evidence based policy development and monitoring by the Commonwealth, States and
Establishment of the website will facilitate important outcomes of the Data Action Plan:
       Facilitation of shared objectives
       Reduction of duplication of data collection
       Reduction of conflicting policy advice
       Development of opportunities for transport providers to collaborate on research
       Development of commercial opportunities for data analysis
As well as data Visibility, there will be other recommendations to the November ATC about the
Transportation Data Action Plan, for example, filling data gaps, improving data quality and ensuring
effective data governance beyond 2009.

                                                                                                Page 10
