1 ITS Action Plan Task 1.3 Digital Maps Stakeholder consultation results 29 th March, Brussels

2 Aims of the stakeholder consultation Develop an understanding of: The organisations involved in the delivery of road data Remit Network coverage Technical aspects Types of data held Standards used Quality issues Accuracy requirements Costs of data collection, aggregation and dissemination Benefits of a harmonised approach Future visions for data sharing between the public and private sector Slide 2

3 Who engaged? Online survey open for just over 1 month 78 complete, 41 partial responses 90% public sector, 10% private sector Interviews with 15 organisations Not necessarily a representative sample France United Kingdom Austria Germany Belgium Netherlands Ireland Czech Republic Denmark Finland Poland Sweden (blank) Estonia Hungary Lithuania Norway Slovakia Luxembourg Romania Latvia Greece Italy Malta Portugal Slovenia Spain Switzerland FYROM Par<al Complete Slide 3

4 Respondents Range of organisations responded to the survey Respondents identified the scope of their activities E.g. public/private; sell/collect data; network coverage General organisation types Type 1 = public, responsible for data collection at a local level Type 2 = public, responsible for data collection at a regional level Type 3 = public, responsible for data collection at a national level Type 4 = private sector However, each organisation has a different scope/remit, and this has an impact on their responses to the questions Slide 4

Collecting data Types of data collected Geometry Safety related

The majority of data collected is basic geometry data 40% 20% 0%

Limited collection of other data 60% 40% Potential implications?

5 Collecting data Types of data collected Geometry Safety related data 100% 80% 60% Traffic management rules What does this tell us? The majority of data collected is basic geometry data 40% 20% 0% Network geometry Lane info Slope Banking Local Regional Na<onal Limited collection of other data 60% 40% Potential implications? Limited support for certain applications 20% 0% Local Na<onal Slide 5

6 Collecting data (cont.) Who collects the data Mixed ownership (the organisation themselves [50-65%], contractors, third parties) What does this mean? Limited control over the data chain Potential impact on the ability to share the data Need a robust approach to assuring the quality of that data across the data chain Slide 6

7 Managing data Quality management Use of quality procedures (c. 55%), reinforced by standards Variety of update methods Varying time between updates What does this tell us? Potential impact on the use of the data on downstream applications/services 120% 100% 80% 60% 40% 20% 0% 45% 40% 35% 30% 25% 20% 15% 10% 5% 0% In place Documented Based on standard Quality procedures Geometry Safety- Related Traffic Management Update Method Periodic Don't know No Yes Updated when changed Combination of periodic and change- based Other Slide 7

channels Range of methods If the data is published in a physical format it requires additional processing to make it useable by 3 rd

8 Sharing data Issues affecting the sharing of data Access conditions Some organisations grant access to their data Others do not Others apply certain restrictions to access The basis for collecting data can have an impact on the availability of that data Publishing channels Range of methods If the data is published in a physical format it requires additional processing to make it useable by 3 rd parties 80% 70% 60% 50% 40% 30% 20% 10% 0% Physical (paper) Physical (data carrier) Online viewing Online data Other Na<onal Regional Local Slide 8

9 Costs of data collection Varying costs between organisations, types of organisations, MS Slide 9

10 Costs Basis for varying costs Reasons for collecting the data Quality requirements Type of data collected Method of collection Downstream use of the data Format of the data Method of dissemination Slide 10

11 Benefits of a harmonised approach Support the certain applications/services e.g. ADAS Helps to meet safety targets Support the commercial exploitation of data Identify the true costs/benefits of data collection Improve efficiency within an organisation Enhanced comparability of data sets Support cooperation between different parties Providing a reliable basis for a data or information exchange model Slide 11

12 Future visions for sharing data We invited comments on what the ideal future model of cooperation between the public and private sector might involve Examples of public sector views: Review the licensing conditions to make it easier to share data Data to be provided to all stakeholders at production costs Reciprocal agreement between public and private sector authorities Public authorities publish only network change data Slide 12

13 Digital Map Providers - Data Collection Sources for construction of digital maps in new markets: Public and private data suppliers and partners Mapping agencies through 1-on-1 relations Road authorities through 1-on-1 relations Aerial photographs and satellite imagery Proprietary survey vehicles Advanced positioning and inertia instruments (odometer, gyroscopes) Cameras providing a 360 degree view Light Detection And Ranging (LIDAR) Increasing use of crowd sourcing Floating vehicle data Navigation user feedback Community based map editing Less dependency on public sources for map updating ITS AP - Digital Maps: Online survey results Slide 13

14 Digital Map Providers public cooperation Currently one-on-one relations with public road and mapping authorities; costly Digital map providers Need standard interfaces to public authorities (i.e. ROSATTE) Need quality assurance for public road data (i.e. ROSATTE) But free road geometry data will kill willingness to invest in high quality road data collection Limit public data to safety attributes (including road and traffic regulation) OSM Community based data will be better and more up-to-date than public and private map data Make all data public for free now (any format) ITS AP - Digital Maps: Online survey results Slide 14
