The role of traffic management in automated driving Siebe

Slide 2
Bottom-up optimisation?
Slide 3
Some guidance needed
Slide 4
Area wide optimisation Bottom-up automation is not the answer,
but Intelligent vehicles work as intelligent sensors Intelligent
vehicles give new types of information Automated vehicles will more
readily accept guidance from area-wide optimisation o Better
compliance improved performance o Better compliance new challenges
for stability
Slide 5
Local optimisation / control Local infra-based optimisation
benefits Optimisation criteria can be based on network policies o
Network-wide o Environment Non-automated vehicles are integrated
Local intelligence can act as conductor Each vehicle plays its own
part, but acts according to a common score Local intelligence
shapes conditions for safety
Slide 6
Early gains from limited automation typical scenario
Slide 7
Early gains from limited automation infra assisted
Slide 8
Evolution of Urban Traffic Control Opportunity Shaping Control
(close to Fixed Time)
Slide 9
Evolution of local controller From: Device with infra-based
sensors Actuation through man-interpreted signals Lots of cables,
physical sensors and actuators Difficult to configure Expensive
(prime example: Traffic Light Controller) To: Network of sensors
and control nodes o Traffic control o Lighting control Cooperative
communication Communication node Local optimisation (as part of an
area network) Self-configuring Inexpensive Unobtrusive
