Already existing parking (especially curbside parking) should be priced to reach approximately 85% occupancy. Less, and you are leaving too many spaces empty, higher and people have to cruise for a while before they find a spot.

That pricing will not discourage too many people directly---because you price it exactly at a point where not too many people are discouraged. (That point might have to be adjusted over time.)

Like a congestion charge, you shift from people bidding with their willingness to sit in traffic and endure queues, to people bidding with their chequebook. (Interestingly, your mix of parkers would shift towards more people who value their time more than their money. Affluent customers are good customers!)

Congestion charges worked out well for Singapore and London.

Politically, it's a good idea to hand out the fees from parking at the same level as the people who can decide about it. So if local opposition could derail the scheme, you have to hand out the proceeds very locally. Otherwise you get the political dynamics you describe.

Charging for parking is relatively easy and does not require high-tech. For example Singapore uses a scheme (amongst others) where you buy a bunch of perforated cards. When you want to park, you take a card and push out the appropriate chads to indicate the date and time of day and display the card in your car's window. Each card is valid for an half-hour slot. You can punch out multiple cards with consecutive slots. Each card can only be used once (obviously).

(If you want a crud variable pricing, you can require people to display multiple simultaneous cards for peak hours.)

I have also seen a system where you send a premium SMS with your licence plate number to pay.

Except that you're admitting to discouraging 15% of the customers. If there isn't enough parking for everyone then the shops much prefer people to be cruising around so that as soon as a space opens up there is someone to take it, rather than not showing up in the first place because they can't afford parking.

You can't actually make more money strictly by losing profitable customers, even if the customers you lose are below average customers.

It is like a congestion charge, which have exactly the same problems.

They keep poor people off the roads so rich people can use them, anyway.

People don't use the high-tech stuff because it's harder. Either way you need something vs. the alternative where you don't need anything.

The problem is there are no "proceeds" -- the money is going to come from the local residents whether it's parking fees or taxes. The only way you can save anything is to have fewer parking spaces, which nobody is going to allow until after there is already a better alternative in place.
