Slide 2: Background

Rear-end collisions - caused by slow/stopped traffic
Queue warning systems (QWS): Timely reaction of drivers facing the queue
Connected vehicles-based BOQ estimation: Faster and more accurate

[This slide contains a photo of the queue warning symbol with LED technology.]

Slide 3: BOQ Estimation Methodology

[This slide contains a flowchart of the BOQ estimation methodology steps.]

Slide 4: Results

Estimated queue lengths: connected vehicle-based vs detector-based and ground truth

[This slide contains two charts of results from estimated queue lengths: the worst TCA Run and the median TCA run.]

Slide 5: Results

T-test Conducted for Determining the Effect of Queue Warning System on the Number of Rear-end Conflicts Resulted from the SSAM (Surrogate Safety Assessment Model)

[This slide contains a table of the results of tests conducted for Determining the Effect of Queue Warning System on the Number of Rear-end Conflicts Resulted from the SSAM.]
