Top Safety and
Security Application
Q-WARN: Queue
Warning
Key data and
communication needs discussion points
Can use variety of
mobile wireless comm.
Need queue detection
technology , whether probes (highly preferred) or infrastructure
Need sufficient
warning time
Synergies with reqts
for other safety applications as well as dynamic speed harmonization
Distinguish between
warning and alert: this is more of an alert
Key research
needs
Tuning algorithm:
parameters for triggering and sending alerts, and response time for alerts
Queue detection
algorithms
HMI and driver
distraction
Develop
arterial/intersection extension to this application or to other hazards, e.g.,
work zones, fog, etc.
How close can this
application bring us to the transformative target?
One study: About half
of rear-end freeway crashes are end of queue crashes
