Denver has tried something very similar with a "supply/demand" fee, where the HOV lanes have been converted to a combination HOV/transponder-based lane. During early hours before and after "rush hour" the fee is something like 75 cents. During rush hour the fee is more like 3 dollars to go some 5 or 6 miles. While it does not solve the congestion problem by any means, it allows for some alleviation of frustration for the price of a latte.

but charging people is not the best way to keep the traffic congestion down! If the problem is too many cars then they should either widen the freeways, or if that isn't a possiblity (such as in New York City where the freeways are already as wide as they can be because they have run out of space) then put traffic lights at the freeway entrys to make so a steady but smaller stream of cars flows onto the freeway.

I really want this guy to run for governor. The I-5 corridor is an abomination.
