This article describes exactly why the NS (Dutch Railways) provide a cheap card (which is even on sale like half the year) allowing one to get 40% off the fare provided they travel during off hours. The off hours are: mo - fr between 9 AM and 4 PM & from 6.30 PM till 6.30 AM, weekends, and holidays. If you check in, it counts from that time (even if you swap trains or travel for 3 hrs straight into peak hours).
There's a few more versions of the card which are essentially trying to achieve the same, just assume you travel in higher volume. For example, there's a more expensive version of the card which makes travel completely free in the weekends.
Thing is, people who work get the travel costs reimbursed from their employer so they generally don't care. Its up to the employer to adapt. And given you can game the logging in time I am not sure how effective it is to decrease congestion/pressure.
I've also noticed the effect on my partner's job. She works 4 days a week, and wants one day off. Well, the most popular days to take off are Wednesday (because it is in the middle of the week) and Friday. Same with taking days off. Some days and dates are popular, for social reasons. Someone who is antisocial won't have much understanding for that, just like you put.
The power system is another example. At times, the German electricity grid is operating on a surplus!
Yet another example is getting paid 150% of 200% during holidays such as Christmas (which is how it works in horeca).
Fascinating discussion, but just being against social behaviour won't change these situations. There needs to be incentive. Being antisocial or being OK with that with the benefit of receiving a discount seems like a great way to achieve this in situations where it makes sense. Does anyone know examples where it'd make sense, but where it isn't currently applied? Or where it has been tried locally, but isn't implemented world-wide? If you take the toilet flush example: we're not paying for toilet usage in our households (right..?) but we are paying for water. If the price of water would be dynamic based on current demand, and the current demand is transparent, that could decrease demand during peak times just like the other examples do. At the very least, those who cause the congestion pay for it, and pay for the extra costs attached to the peak's effect. On a side note, the thought of highly fluctuating water prices sends shills down my spine.
