Scalable road user charging with a flexible rate structure.

Smartphone-based mileage reporting since 2008.


Flexible mileage reporting options

We provide multiple data collection options for drivers, including through telematics integration, DMV integration, and odometer photos.

We also support data collection using plug-in OBD-II devices, but we don’t believe that’s a smart solution at scale.

Exclude miles on certain roads

For a fairer program that wins driver support, exempt miles traveled out-of-state, on tolled or private roads or near people’s homes.

Not only does this foster acceptance and support, but efficient cross-jurisdictional accounting will be important to every state in the nation.

Dynamic rate structure

Support your policy goals with discounts for low-income drivers, low-polluting vehicles, and traffic-mitigating travel choices.

GoCarma enables you to combine flat fees with rates that are responsive to traffic conditions, time-of-day, location, HOV status, vehicle class, air quality and more.

Personalized engagement

Offer complete in-app transparency and customer support with personalized communications and discounts.

Gaining driver buy-in requires personalized communications with complete transparency and privacy protections. GoCarma has unrivaled experience in this area.

Reduce your cost of customer acquisition to near-zero.

RUC programs to date have primarily focused on deploying costly plug-in technologies that don’t work in every vehicle, are difficult to install, and challenging to administer and maintain.

With GoCarma, drivers simply download an app.

50 Million Vehicle Miles Per Year

Our RUC solution already logs about 50+ million vehicle miles each year using OBD-II devices smartphones.

A flat per-mile fee is unfair, and a “backward step” for your policy goals.

“The principal advantage of RUCs is not their ability to raise revenue, but rather to variably allocate charges among various types of users and travel. Raising revenue is a primary motivation for any RUC rate structure, but it is also essential to clearly identify and prioritize the economic, environmental, equity and other outcomes to be advanced through the RUC.”

- Mineta Transportation Institute (2023)

Design a RUC program that increases equity and acceptance.

Our end-to-end RUC solution uses smartphones to improve transparency, offer personalized communications and apply fairer pricing for qualifying low-income drivers and low-polluting vehicles.

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.
