There was this multi-level parking garage I was at where right at the beginning of the ramp up to another level, it would tell you how many spaces that level has available or if it's completely full.

I can't figure out how that would work though. how does it count cars?

probably the same way traffic lights detect cars at an intersection, by using induction sensors underneath each space

I think you'd only need one sensor per level, and then count the cars going past each sensor. Knowing how many spaces are on each level, you could calculate how many cars are on each then determine how many are free.

You'd probably need one sensor at the entrance counting cars going in, and one at the exit of each floor counting cars leaving so that you know when spaces free up.

Some airport parking lots and rental car places have individual inductive sensors in each parking spot. And they also have signs above the spots to show if the spot is in use or if the car is reserved for a certain person.

Problem is it doesn't take into consideration cars entering and leaving the area. :(

BWI airport's garage has this.

There are sensors above each of the parking spots with a small LED light. The light turns red when a car pulls into the spot and turns green when it leaves the spot. All the sensors are networked together, and there are signs throughout the garage that say "No available spots" or "x spots here", with arrows directing you where to go. It's an extremely effective system, and makes finding a parking spot incredibly easy.

efficient no doubt, but I can forsee a major problem.

there's one parking spot left and 3 motorists are guided by arrow coming from different directions. who will get to park there? the one who get there first or the one who sees the arrow first? I think accident will increase as people scrambling to follow the arrow and ignore everything else.

There are signs everywhere in order to eliminate situations like this. There's a spiral ramp at one end of the garage with exits to each floor. At the ramp exit, you see how many spots are available. Then there are additional signs at each aisle. If there are only three spots on a floor, logically you would drive up to the next floor. Similarly, if there is one spot in one aisle and 5 spots in another, most people will go for the 5 spot aisle. I've never encountered a situation in the garage where more than two cars all went for the same spot.

as i implied, seems really unnecessary.... if you have a one way system with a gate that only lets in when someone comes out (when it is full), then you all find a space- works fine at all the multi-level car parks i've been to...

That works with people walking to stores and museums and such. Not with cars. They use inductive technology to detect the large amounts of ferrous metal in a car passing over it. Unless you're carrying a 20lb piece of steel with you, you won't trip it.
