§Performance Observer
□Derived from BSM Data
(Trajectories)
□Process Trajectories to
compute observed
▪Delay (Average,
Variability),
Travel Time
(Average, Variability), and Traffic States (Queue Length)
□Performance Measures
Used for
▪Monitoring and Assessment, DSRC
Performance, and Section Level Control (Coordination Updates)
§Approach
□Defining appropriate
performance measures and metrics
▪Traditional: Overall
Vehicle Delay, Number of Stops, Throughput, Maximum Queue Length, Total
Travel Time
▪More recent: Time to
Service, Queue Service Time
▪Connected Vehicle
System: DSRC Range, Packet Drop
□Understanding how
improvements to one mode may impact another mode
□Understanding how
connected vehicles information, can help to estimate performance measures
