Experiences and challenges with standards for location referencing from the GIS and ITS domains

Intelligent Transport Systems (ITS) for driver assistance, from basic route planners to systems for autonomous driving, depend on geospatial road information from various sources. One important source is authoritative information from road authorities concerning road networks, restrictions, traffic information, etc. ISO and CEN standardization committees in the domains of geographic information (GIS) and ITS have developed several standards with models, location referencing methods and exchange formats for geospatial information. Road authorities are maintaining information in systems based on GIS standards, while the exchange formats and the receiving systems on the ITS side are based on standards from the ITS domain. The senders and receivers of data will need to handle the different conceptual models and exchange formats from standards in the two domains. This paper presents an overview of relevant standards and specifications, identifies challenges related to interoperability, and suggest future research.
