Peak Pricing

Hey, DC Metro people: Here's an idea: stop charging based on distance, and start charging based on congestion. The marginal cost of adding one more person to an empty train is basically zero, regardless of how far they travel. But the marginal cost of one more rider on a crowded train is an additional iota of misery for everyone on board the train. Distance based policy just discriminates against long-distance travelers.

The system already tracks where someone gets on/off. Correlating that to their location, and the location on a train during a peak period is trivial. Then you can charge them for it. Some people might get surprised; add a 'peak' light to the train, and start charging on stations after that.
