Virginia's $40 Toll Road Better Be the Future of Driving

The main driver was that Southern Virginia had the political power at the time and refused to allocate money for roads in the north, preferring instead to build multi-lane highways to nowhere in the south. It's all different now with the explosion of the size of the federal government increasing the population of the north so that they're now in the driver's seat - 30 years too late now that the growth has occurred.
They did build the amazing HOV lanes on I95/I395 that manage to fit 2 lanes of traffic into the same space where 6 lanes could have been built. The 2 lanes change direction mid day further inhibiting traffic.
I never understood how they got these numbers.
* commuter average hourly wage * time spent in traffic (basically time the commute took in traffic minus the amount of time the commute would hypothetically take if drove at the speed limit)
That's easy although imperfect...might also want to account for other things like delayed meetings due to traffic.
