What are Turnstiles and Pedestrian Control Gates?

turnstiles

Turnstiles are a form of gate that allows one person to pass at a time in one direction. Also known as a baffle gate, they can be accessed by payment (coin, token, or card) or are used  simply to count the amount of people passing through and control the amount of people entering through a point. They are often found in amusement parks, airports, or subway terminals. The word “turnstile” is derived from the word “stile”, which is a type of fencing generally used for livestock that is structured in such a way (using steps, ladders, or narrow passages) that allows humans to pass without using a gate and without the risk of livestock escaping. There are three main types of turnstiles: waist-high, optical, and Roto-gates
