2  Brief outline of the Project - Scope, Deliverables - Progress to Date  Other relevant projects  Where to from Here – A possible Action Plan  Conclusions

3  A road centreline with added intelligence that can be used for EM proximity based dispatch, planning and recovery, route planning, in vehicle navigation and tracking and route analysis and modelling, consistent with national standards and models.  A Business Case outlining possible routable road centrelines models, metadata standards, data collection and maintenance processes and recommendations for implementation incl. resource and funding requirements.  A Business Case identifying potential commercial and non- commercial models for ownership, distribution and usage.

4  RRCN Data Study 2006 (purpose: to investigate data requirements and identify possible sources of data  RRCN Working Group – (objectives: to follow up on the recommendations of the Data Study)

5  Several road centreline data sets – need to leverage current maintenance processes  Several road data custodians: Main Roads, Landgate, LG, FESA, PTA  Different approaches to representation and maintenance: MRWA data centric, spatial added, Landgate spatial first, data added…

6  Speed limit – Main Roads  Flow direction - LG, Landgate, significant maintenance program ongoing basis  Turning restrictions – as above  Height and Weight restrictions – Main Roads’ relationship between this data set and centreline data set  Temporary road closures – all road owners  Street addresses (incl parks, forest etc) - Landgate

7  Undertake a more detailed assessment of requirements, costs and practicalities of implementation, particularly ongoing maintenance  Improve the maintenance and quality of existing data sets  Adopt a staged approach: limit the data sets only to high priority, limit the scope to Metro at the beginning  Develop the data sets in line with the national framework and metadata standards and international standards

8  Intelligent Access Program IAP (managed by Transport Certification Australia TCA Limited)  The IAP is a voluntary program which provides heavy vehicles with improved access to Australia’s road network in return for monitoring of compliance with specific access conditions by vehicle telematics solutions.

9  Intelligent Speed Adaptation (ISA)   ISA is the generic name for systems where the vehicle ‘knows’ the speed limit and is capable of using that information to give feedback to the driver (advisory systems) or limit the vehicles’ speed (supportive systems).  How does it work? - A device fitted to the car and mounted on the dashboard alerts the driver to the speed limit of the road on which the vehicle is travelling, by taking bearings from satellites. - The device in the car refers to detailed maps of the surrounding road network in order to inform the driver, by means of an alert and flashing speed zone symbols, of the vehicles’ current speed and when the speed zone changes. - In supportive systems the vehicle can be gradually slowed down to the speed limit by reducing the quantity of fuel flowing to the engine.

10  PSMA Australia Limited   A public company owned by the state, territory and Australian governments.  The Transport and Topography dataset is underpinned by a road centreline layer of over two million kilometres of roads, together with more than 30 feature types within transport, hydrology and green-space themes.

11  Intergovernmental Committee of Surveying and Mapping (ICSM)   ICSM is made up of senior representatives from New Zealand and Australian (Commonwealth, States & Territories) government surveying and mapping/charting agencies.  Provides leadership, coordination and standards for surveying, mapping/charting and national requirements for national network data sets  A Harmonised Data Model (HDM) that consolidates the data models for the Australian Spatial Data Infrastructure (ASDI) and incorporates cadastre, topography, place names and street address.  HDM - a hierarchy of models to assist distribution and interpretation using Unified Modelling Language (UML) according to ISO Extensible Mark- up Language (XML) has been adopted as the encoding mechanism for the transfer of spatial data.

12  Euroroads   The main objective for the EuroRoadS project is to build a platform for a European road data solution through a specification framework and enable uniform and efficient data transfer between data road producers and providers of information and services to road users  Specification Framework: -road network information model (defines road feature types and method for relating attributes and features to the network) -Specifications for data exchange model and format and metadata Catalogue

13 A possible Action Plan includes identifying and assessing potential road centreline models against Requirements. -Road Network info requirements– who owns and provides the roads (e.g. state roads sourced from MRWA, LG roads sourced from X, FESA roads sourced from Y) network defined by road no, name? crway -Centrelines representation requirements e.g. intersections, roundabouts, lanes, ramps, carriageway, connectivity -Data requirements (street address, posted speed, access restrictions etc), best data source and data quality assessment against minimum quality specifications -Issues re how to attach data to road centreline for each model -Ongoing Maintenance issues (of centreline plus attached data) for each model Potential road centreline models: Landgate, MRWA, Hybrid Limit the scope to Metro

14  A lot of good will and good work so far  Improved understanding or each other business, needs and modus operandi  As no funding, continue the work through the current RRCN WG  Need to consolidate findings so far and start developing the BC  Develop and Agree on an Action Plan to support the development of the BC  Built on existing international and national metadata standards and data management framework  Focus on assessing the road centreline model, data requirements and ongoing maintenance needs, and not on ownership and distribution of the end product
