How It Works

We developed an HOV occupancy detection smartphone app that leverages the concept of VOD camera technology to accurately count and verify vehicle occupants. 

With just one smartphone, carpoolers can declare and verify their occupancy in about 5 seconds or less.

Proprietary Technology

Realness Verification

Mitigates any attempts to manipulate the verification process with pictures, mannequins, or videos. 

Facial Image Differentiation

Accurately differentiates occupants by comparing facial features.


Measures space deltas between occupant faces to optimize verification performance. 

Group Verification

Detects and verifies carpool occupants in approximately 5 seconds. Verification can be completed with a face mask, sunglasses, in all lighting conditions, and with children.  

Group Occupancy Verification

Agency Integration

Our VOD smartphone technology can be integrated with agency back-office systems through an API call or directly connect with transponder readers with a Bluetooth Low Energy transponder tag. The app can also fully integrate with advanced agency customer relationship management tools. 


RideFlag has numerous patents to protect its technology. These patents assure agencies that we have the full Freedom to Operate.
