Vehicle Occupancy Verification for Toll Road Discounts

Road operators have for years invested massive resources trying to enforce High Occupancy Vehicle (HOV) rules on various types of facilities including: toll roads, high-capacity, managed or express lanes, carpool and diamond lanes.

Current methods of manual enforcement are unsafe, contribute to network degradation, and erode public trust in lanes that are intended be premium lanes that serve as a faster alternative to general purpose lanes. 

GoCarma removes the high-risk of roadside enforcement, and changes the focus from enforcement to verification in the most intuitive hands-off way that technology allows.


GoCarma allows toll operators to focus on mobility, and get out of the business of enforcement.
