EU EIP sub-activity 4.1 “Determining Quality of European ITS Services” has been dedicated to establish frameworks for quality assessment in several ITS data and service domains.
One product of this sub-activity is a quality framework for the domain of Intelligent Truck Parking Information Services (ITPS). This framework, called the ITPS Quality Package, defines quality criteria, quality requirements and assessment methods for ITPS across Europe. It has been published here:
As a follow-up action, the ITPS Quality Package has been validated under real-life operating conditions in the Netherlands and in Germany. The Netherlands validation has been already reported here:
These EU EIP elaborations were presented to about 20 truck parking stakeholders during an online workshop on December 17, 2020.
The workshop goals were to:
- learn about the current elaboration of the ITPS Quality Package,
- learn about the recent validation tests,
- discuss quality aspects and issues with the EU EIP team and other stakeholders, and
- give input for the upcoming work by EU EIP.
In the first part, Peter Lubrich, Radu Milea, Florin Vaduva and Michel Kusters from the EU EIP Quality group presented the background, motivation and working structure for the ITPS Quality Package, as well as the validation results, see the presentation.
Some new insights into the current ITPS Quality situation could be derived from the recent validations in the Netherlands and Germany. The Dutch validation looked on how individual quality criteria are met by the information basis in the National Access Point, based on ground-truth comparisons. One of the observations was that quality levels for public vs. private truck parking operators were quite different. Additionally, it was revealed that some private parking operators are not willing to expose their data on the NAP, to keep the number of clients rather restricted.
Within the German validation, the completeness of records about truck parking facilities, as provided in the National Access Point, was checked, looking at the mandatory data fields from the DATEX II profile. It was found that some basic data fields (such as geolocations) are mostly provided, whereas some other fields (such as service facilities) are only occasionally provided. Further, the completeness levels differ when looking individually at the German Bundesländer.
Both validations also indicate that the definitions from the ITPS Quality Package are stable. i.e. the criteria can be replicated in real-life environments, and quality requirements seem to be at reasonable levels.
Next, an open session was opened to review the approach of the EU EIP activity, and explore quality requirements by present ITPS experts. The following questions were discussed:
- Are the EU EIP quality definitions sufficient for a common understanding on Truck Parking Information quality?
- What is your experience on data quality from external providers?
- What is the role of private parking operators in the data eco-system?
- How to do quality checks for data about truck parking places?
The feedback on these questions was collected using a Miro Board, see here for results. Accordingly, data quality issues are important for the audience in terms of building a solid information base for the individual services. However, other issues seemed to be also important, such as the business perspectives of truck parking operators. It was stated that costs and benefits for delivering data (according to EC Regulations) do not always pay off. Further, audition procedures of truck parking facilities, to meet EU minimum standards, is another burden for such operators. For the Quality work, this means that the data perspective has to be put in a wider context, also reaching out to strategic and business goals of stakeholders in the ITPS domain
As one of the workshop benefits, new relationships were built between the EU EIP Quality group and dedicated ITPS experts and actors. The EU EIP Quality group will foster future exchange with these experts and actors in terms of quality issues.
