How do parking garages work




















Heres how emergency brakes work in your carThe parking brake is used to prevent the vehicle from rolling down an incline. How the system works. What happens if you lose your parking garage ticket. More advanced systems will. Others will have a ticket station when you enter. You can own 6 properties apartments garages stilt houses condos each can store anywhere from personal vehicles Max.

Most parking garages have clearly signed entrances and exits. Parking garage entrance with an automated barricade 2 Parking garages often require you to pay a fee or pick-up a ticket before you enter. As you slowly drive into the entrance of the parking garage, look for a ticket booth or parking attendant. Make sure that you carefully steer your car through the entrance equipment. Make a payment or pick up your ticket. A man getting a ticket to pay later at the exit. Entrance to parking garages are usually controlled by an automated barricade.

After you have made a payment or retrieved a ticket, the automated barricade should open. Wait until the arm is in the upright position before driving your car into the parking garage. Do no stall underneath the automated barricade. Be aware that parking garages often have very low clearance. If you drive an especially tall or large vehicle, you should practice good judgment before entering the parking garage.

Drive through the parking garage slowly and with caution. Watch for hazards such as confused pedestrians looking for their vehicles, drivers backing out of parking spaces without noticing you approaching, and vehicles emerging from behind a corner of the parking garage.

In dim light, switch on your low-beam headlights to make your vehicle more visible to others. Meanwhile, you're getting honks from the cars lining up behind you and cursing that lying "space available" sign. You look at the clock — 31 minutes to takeoff. Even though more parking garages have upgraded to automated car-counting systems, some of the busiest lots seem to suffer from inaccurate tallies.

Actually it's the customers who suffer, teased into a dead-end corner of the lot with promises of open spaces, only to be forced to execute a point turn and retreat in failure. To understand how parking garage counting systems work — and why they often don't work — we spoke with Dale Fowler, company director of Indect USA , a division of an Austrian firm that designs and installs advanced parking guidance systems for airports, hospitals, malls and casinos around the world.

His company's bread and butter is a single-space system that mounts a sensor over every single parking spot in the garage and indicates open spaces with easy-to-spot green LED lights.

One of the company's first high-profile clients was the Dubai Mall 15, parking spaces. Since every space is fitted with its own ultrasonic sensor, and every sensor is But older parking garages are more likely to be using induction loop sensing technology. That's been around for 50 years and is prone to some counting errors. Induction loops are coils of wire that are cemented under the road surface at the entrance and exit of a parking garage.

They work like a metal detector — just the same way one would work at the beach if you were looking for jewelry. In this case, the loop registers disturbances in the coil's electrical field caused by metal objects large enough to be a car.

Parking garages will place a pair of induction loops at the entrance — one to trigger the ticket box and gate, and one to confirm the direction that the vehicle is traveling. The same two-loop system is used at the exit, to raise and lower the bar as a car leaves. The most basic system will count the number of vehicles coming and going and keep a running tally of how many spots are still available.
