Experiences Problems
Quality assurance for incident management on
the local leve link control
Traffic and weather monitoring Data errors
LCS Overview
Experiences
Automatic Incident Detection (AID) Undetected
incidents, late detection False alarms Lots of
parameters ? no optimisation means
Quality assurance
New control system
Conclusion
Incident management Strategies not adapted to the
traffic situation Inconsistencies between messages
