Motivation and Challenges
• Mobility remains important
• Solutions need to be sustainable
• High demands on mobility in urban areas
• Increasing safety standards in urban traffic (not just on freeways)
• Assistance functionalities should be linked and coordinated
• More intelligent traffic infrastructure needs to be deployed
• Energy efficiency should be improved in future vehicle & infrastructure design
• The driver should be supported according to the demands of city traffic

„Networked Traffic System“
Sub-project „Smart Intersection“
• The sub-project “Smart intersection” addresses the area near urban intersections
• Improvement of sub-optimal traffic by information, communication, cooperation and driver assistance.
„Better stopping“ and „better waiting“Driving tactics for long red phases and extended start-stop
„Better entrance to intersections“Optimizes entrance to an intersection/
adaption of driving to signal coordination
„Better decision support“Traffic horizon for local traffic state and turning restrictions
„Better starting“Increased alertness and automatic starting
„Better stopping“ and „better waiting“Proactive following by situation adaptive starting strategy
