§System
Functionality and Performance
□INFLO system delivers
Q-WARN and SPD-HARM messages to the drivers at least 1 mile in advance of
congestion.
□INFLO system delivers
messages to drivers within 5 seconds of detection of congestion.
§Algorithm
Performance
□With adequate market
penetration, connected vehicle-based speed data by itself can provide estimates of
the location of the back of the queue and the length of the queue that are
comparable to that provided by infrastructure-based speed sensors only.
§Measured
Driver Behavior
□On average, there are
fewer panic stops as indicated by longitudinal deceleration.
§Driver
Feedback
□On average, drivers
report that they find Q-WARN and SPD-HARM messages useful, valuable and
appropriate for traffic conditions.
□On average, drivers
report that they believe Q-WARN and SPD-HARM messages will improve safety by
notifying them of slowed and congested traffic ahead.
