Express Lanes Queue Study
Kestrel Data collected interstate queue data along the I-77 managed lanes corridor from I-485 north of Charlotte to Langtree Road near Mooresville. Kestrel flew a plane over the survey area every thirty minutes to collect high resolution imagery of the entire corridor. From this imagery, engineers were able to determine per lane max queues and bottlenecks at each on and off ramp through the corridor.
Individual images captured every 3 seconds as plane traverses over highway.
