Cooperative intelligent transport systems have been identified as an enabling technology for solving several of today’s traffic systems challenges. Several initiatives to standardize vehicle-to-vehicle and vehicle-to-infrastructure communication exist and numerous applications intended to increase driver awareness have been developed. To fully exploit the potential of communication we argue for the need to standardize a minimal ontology of concepts and relations relating to the road transport domain as well as a format for exchanging sets of behavioral rules expressed using the ontology. We identify traces of ad-hoc behavioral specifications already in the current standards for vehicle-to-vehicle and vehicle-to-infrastructure messaging and show that the need for expressing behavior becomes clear when considering applications such as emergency vehicle warning, platooning and intersection control.
