Proven technology for stopping an HOV violation in its tracks.

Roadside HOV enforcement belongs in the rear view.

Roadside enforcement results in >30% HOV violation rates, and puts law enforcement officers at a high risk.

Verify HOVs accurately on any road using smartphones.

Our results show <2% HOV violation rates, without any requirement for law enforcement spot checks.

Success in the South

Dallas-Fort Worth, TX

80,000 people use the GoCarma app to qualify for HOV toll discounts across the nation’s largest network of managed lanes.

We reduced HOV violations from >30% to <2%, processing half a million monthly HOV verifications.

Our latest project

Baton Rouge, LA

GoCarma was selected by LA DOTD to operate a new 16-mile HOV Lane. The city’s traffic is ranked 4th worst in the U.S. Our end-to-end solution ensures HOV lanes are enforced and drivers save time.

Mark Compton, CEO of the Pennsylvania Turnpike Commission and former IBTTA President

“Carma’s groundbreaking technology makes it easier for toll operators to keep track of HOV drivers and reward them by charging them less for doing their part for the environment.

Automating the process of verifying occupancy on these roadways also eliminates the need for roadside enforcement, which makes the road safer and less congested.

All in all this is an innovative solution that we’re sure will catch on among tolling operators across the country.”

For us, it’s personal.

GoCarma’s customized in-app communications system offers customer support, discounts for low-income drivers and low-polluting vehicles, plus traffic announcements, surveys and live chat sessions.

GoCarma makes it easy.


Automatic Activation

GoCarma awakens when you drive on certain roads, even if the app is fully closed on your phone.

No driver distraction. No forgetting to flip a switch. No unnecessary GPS tracking. No battery drain. No roadside camera, or cops.

Real-time Verification

The vehicle’s HOV status is verified based on the coordinated proximity of GoCarma app users in the vehicle.

For children, and those without a smartphone, GoCarma provides a Bluetooth-enabled Occupant Pass that is carried in the vehicle.

AI Fraud Detection

Persistent HOV cheaters are identified through big data analysis of anomalous usage patterns.

Drivers receive a series of escalating in-app warnings, before account suspension or violation penalty.

With 2 simple APIs, connect to any existing toll system to confirm HOV eligibility.
