Road Charge Projects

Technology is changing the way Californians move around the state. Not only are people driving more fuel-efficient and electric cars, they’re also using rideshare apps instead of driving. Use of transit and active transportation is growing. Freight patterns are shifting. Government agencies and private companies alike are also testing autonomous vehicle systems. The landscape of how we travel in California is changing. We have to prepare for the future and that includes how we fund road infrastructure.
