You need location info in addition to distance since roads and infrastructure are owned and maintained by various agencies. The solution could be to build upon EZPASS. Have the EZPass readers in every signboard or lamppost along the highways. They can read and record distance travelled along a particular highway so that revenue can be attributed to appropriate agency.

This is a proposal to replace the gas tax, which doesn't give you that information today. So I don't see how it's required?

We could divide the money how we do today, or could sample road usage to estimate an appropriate division. We don't need per-car level data.
