Project Goals Determine where WWDs are occurring
Determine what the driver was doing before the
incorrect movement was made
Did they self correct quickly?
After a pattern is determined, treat specific
area with enhanced signing, painting, and
lighting. (Low-Medium Cost)
If problem continues, use ITS (Medium cost)
May need to consider geometric changes
(High Cost)
Notify 911 centers to intercept (was #2+

Quickly moved to look
at system that „detects‟ WWD
Created a “Test Bed” and invited
vendors that claim they can do wrong
way driving detection (using video
analytics)
Performed testing November
What is “Video Analytics?

“Test Bed” Evaluation Found that Video Analytics is mature
enough to detect Wrong-way driving
Still must deal with „False Positives”

Current Status
One vendor has allowed us to continue
to test
Funding for corridor deployment has not
been approved yet.
Other companies are taking note and
coming up with new systems

Positives of “Point of entry”
Video Detection
Eliminates multiple sensors
Can identify actions before WWD
Confirm / Remove False Detections
Can find out what was going on during
self correction phase
Speeds up time to determine problem

After system was turned on, Nov 13 it
detected 2 WWD within a few weeks.
One 100% positive, one 98% positive
Waiting for 3rd…. But that took 7 more
months. 3rd one

Lessons learned
Must have video confirmation
Locations that you don‟t think a WWD
would happen, actually do!
10 second video clips are too short
Combination of entry points and mid
interchange are a good idea.
Test daily (8am, reverse flow detection)
