On May 9, 2023, the 19th Open Auto Drive Forum event was held at HERE in Chicago, USA. Originally planned as an onsite-only event, it was eventually also possible to participate online. The event was opened by Jeff Raimo, Sr Director Product, at HERE. He welcomed to Chicago and introduced UniMap, HERE’s mapping technology that creates fresher and more accurate maps. Following good tradition, Andras Csepinszky of NNG, spokesperson for OADF and co-chair of SENSORIS, gave an introduction to OADF for those attending for the first time. He then led through the agenda and moderated the sessions, assisted by Stephanie Chaufton (TISA), who looped in the online participants and managed the polls and presentations.

By popular demand, NDS technical coordinator Fabian Klebert was invited to the meeting to explain the role of serialization in the various standards and why the NDS chose zserio rather than Protobuf, which is used in many other standards. In his presentation, he compared the two approaches in detail in terms of features, code quality, data size, and encoding/decoding speed. In summary, NDS chose zserio over Protobuf because it is smaller, faster, allows for more advanced schemas, and supports the development of ASIL-compliant solutions.

The second invited talk was given by Takeshi Doihara, ISO/TC204/WG3 Expert and ISO/TC211/JWG11 Co-Convenor for the Geographic Data Files (GDF) standard. He first explained the scope of ISO/TC204 (Intelligent Transportation Systems) and TC211 (Geographic Information/Geomatics) and the importance of these standards for GDF development. Another focus of his presentation was the difference between GDF5.1-1 (GDF 5.0) and GDF 5.1-2 and the feature representation in GDF5.1. Furthermore, he reported on the harmonization between GDF and ISO 191xx and the planned revisions of GDF.

As in all OADF events, the OADF member organizations and ASAM reported on their recent activities:

• Jean-Charles Pandazis, ADASIS Coordinator and from ERTICO, reported that ADASIS v3 – 3.0.0. has just been released internally. It includes new profiles for speed limits and a request-and-response mechanism. ADASIS is also preparing a White Paper to be released in the coming months.
• Benjamin Engel, CTO at ASAM, gave an overview of the OpenX standards, with particular focus on the Offroad Concept Project, the ASAM Text Specification, and the ASAM OpenODD.
• Martin Schleicher, NDS Chair and Elektrobit representative to NDS, gave an overview of recent advances in NDS.Live, which is now available for evaluation purposes also for non-NDS members and explained how NDS.Live can now be used to distribute map data in various scenarios.
• Andras Csepinszky, Co-Chair of SENSORIS and Advanced Automotive Technology Director of NNG, reported on the latest SENSORIS version 1.6 and the planning for SENSORIS 2.0.
• Satoru Nakajo, SIP-adus founding member from the University of Tokyo, reported on the results of the SIP-adus program in Japan, which ended in March 2023, and on planned follow-up activities.
• Matthias Unbehaun, TISA Executive Director, provided information on TPEG2 and the requirements and ongoing discussions of the follow-up version related to automated driving.
• Christian Kleine, TN-ITS President and from HERE, introduced TN-ITS and reported on progress towards alignment with DATEX II and TN-ITS.

At the end of the event, Steffen Kuhn from Elektrobit organized a workshop on reliable maps for automated driving for the on-site participants. His teaser presentation on this topic sparked a lively discussion about Reliable Map Attributes (RMAs) and RMA deviation types. As a result of the discussion, the OADF will work out more detailed and more concrete recommendations for making maps highly reliable and align with other ISO working groups on the definition of map data quality attributes.

OADF looks forward to celebrating its 20th meeting with the next event. The date and venue will be announced soon on the OADF website.

The 18^th Open Auto Drive Forum event on November 22, 2022, was attended by more than 100 online participants. Andras Csepinszky of NNG, the OADF spokesperson and co-chair of SENSORIS, warmly welcomed the attendees and recalled the history and goals of OADF. He also gave an overview of recent OADF activities related to reliable maps and the OADF ecosystem.

Steffen Kuhn from Elektrobit introduced to ISO/AWI TS 5083 ‘Road vehicles – Safety for automated driving systems’, which will include a chapter on the use of HD maps in automated driving systems. This chapter will also provide the definition of reliable map attributes (RMAs), their deviation types, and mitigation of risks arising from RMA deviations.

Aria Etemad from Volkswagen gave an overview of the EU projects L3Pilot and its successor project Hi-Drive, of which he is the coordinator. L3Pilot aimed to test congestion, highways, parking, and urban applications. The Hi-Drive project began in 2021 and is scheduled to last 4 years.  It focuses on Automated Driving robustness and reliability, extended and defragmented Operational Design Domains (ODDs), and interoperability between countries and brands.

Trond Hovland of ITS Norway introduced ISO JWG 11 as a joint working group of ISO/TC 204 WG3 ‘ITS Geographic Data’ and ISO TC 211 ‘Geographic information/Geomatics’ and reported on the planning of a new version 6.0 of the Geographic Data Files (GDF).

In addition, the OADF member organization provided information on their recent activities in automated driving:

• Jean-Charles Pandazis, ADASIS Coordinator and of ERTICO, reported on the release of ADASIS v3.2, the planning for v3.3, which will integrate auxiliary providers, and the planning for v3.4, which will focus on a low-level protocol.
