that drivers want exactly where it is needed
only when relevant in a non-distracting way
RONCALLILocation-based and dynamic road (safety) information in real time...
• visual + acoustic warnings when
speeding
• driver assistance system
• large-scale experiments in many
EU-countries
• remarkably good feedback from test
persons
• Prognosis: accident reduction up to 25 %
Intelligent Speed Adaptation
• warnings of sites or sections with high accident rates
• data source = accident database of KfV
• speed-dependent warning
High Risk Sites
• warnings near schools or kindergartens
• data source = information of communities
• speed-dependent warnings
• time-of-day-dependent warnings
• consideration of school-holidays
Sensitive Areas
• warnings only in wet road conditions
• warnings only when speed critical
• Source = survey of arsenal research (RoadStar)
Problems with skid resistance and ruts
• real-time road information directly transferred to server
by drivers
• e.g. in case of congestion, fog or accident

Acci-dent
...
Extended Floating Car Data
• priority information at complex crossways
• ECO-Driving energy efficient driving = safe
