Automating Vehicle Occupancy Verification

At Carma, we believe in rewarding high-occupancy vehicle (HOV) travel. Increasing the number of people in a car is the most effective way to fight traffic congestion, local air pollution and climate change. All over the world, government agencies are experimenting in rewards for high-occupancy vehicles, including dedicated HOV lanes, HOV toll discounts, preferential parking access and road user charging. 

However, until now, verifying vehicle occupancy has been impossible. Most agencies deploy roadside law-enforcement for periodic spot checks, but it's not easy to count people in a car that's moving quickly in traffic, in varying weather conditions. It's also dangerous for the police officers, and degrades traffic flow. Other agencies use automated digital imaging systems for peering inside cars - but these fail for the same reasons. 

Carma's patented system takes a different approach. Our smartphone app automatically verifies your occupancy in a vehicle. It does this by using Bluetooth Low Energy (BLE) communications to detect its proximity to a small in-car device - a Car Beacon - that simply transmits a Bluetooth identifier. In this way, vehicle occupancy is reported to the agency and you qualify for preferential HOV treatment.

One of the great features of the solution is that it requires no user interaction at all. You can keep the phone in your pocket and the app will automatically verify your occupancy. Our product design process focuses on completely remove all barriers to someone adopting behavior change. This is one of the reasons why Carma's solution is ideal for government agencies wishing to verify vehicle occupancy for enabling toll discounts. As you drive through a toll gantry, agencies can simply query for the number of people in your car and apply a reduced rate for carpools.

In this way, Carma is building the future of personal mobility - connected, hassle-free and rewarding.
