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

...

Extended Floating Car Data

• priority information at complex crossways

• ECO-Driving energy efficient driving = safe
