Quality Assured Road Information for ITS-Applications – the Quality Concept of EuroRoadS

For future ITS-applications and particularly for advanced driver assistance systems (ADAS) a harmonised and cross border road data infrastructure of high quality is neces-sary, fulfilling the requirements stated by the car manufacturers. The project EuroRoadS (Pan-European Road Data Solution) granted by the European Commission will lay the groundwork for the creation of such an infrastructure by national mapping agencies, road administrations, private enterprises, and the research sector. The specific challenge regard-ing quality is to prepare a common model describing the quality assured data flow from acquisition and updating of the digital map up to its final application. This paper describes a quality concept, consisting of a quality model for describing information quality in ITS-application and an analysing procedure evaluating information quality within information flow. This concept will be the base for the necessary quality assurance of the entire infor-mation chain. The application of the quality concept will be illustrated by a system draft of a map-based speed alert system
