Turnstiles ensure one person at a time entry and exit through a combination of mechanical design and electronic control systems. The primary mechanism is the rotating barrier, typically consisting of three or four arms that rotate around a central axis. This design physically restricts passage to one person per rotation. When a person approaches the turnstile, they must present a valid ticket, card, or token to unlock the mechanism. Once validated, the turnstile allows a single rotation, permitting one person to pass. The arms then return to their original position, ready for the next user. This mechanical action prevents tailgating, where multiple people attempt to pass through on a single validation. Advanced turnstiles incorporate sensors and electronic systems to enhance security and efficiency. Optical sensors detect the presence and movement of individuals, ensuring that only one person passes per validation. If the sensors detect more than one person attempting to pass, the system can trigger an alarm or lock the turnstile to prevent unauthorized entry. Some turnstiles use full-height barriers, which extend from the floor to above head height, further preventing unauthorized access by making it difficult to climb over or under. These are often used in high-security areas. In addition to physical and electronic measures, turnstiles can be integrated with access control systems, allowing for real-time monitoring and data collection. This integration helps in managing crowd flow, ensuring security, and maintaining accurate records of entries and exits. Overall, the combination of mechanical barriers, electronic validation, and sensor technology ensures that turnstiles effectively control the flow of people, allowing only one person to enter or exit at a time.

Turnstiles and swing gates are both access control devices used to manage the flow of people into and out of a facility, but they differ in design, functionality, and application. **Design and Structure:** Turnstiles are typically waist-high or full-height barriers with rotating arms that allow one person to pass at a time. They are often made of metal and are designed to be robust and tamper-resistant. Swing gates, on the other hand, consist of a single or double gate that swings open to allow passage. They can be made from various materials, including metal, glass, or plastic, and are often more aesthetically pleasing. **Functionality:** Turnstiles are designed to control and count the number of people entering or exiting a space. They often require a ticket, card, or biometric verification to unlock and rotate, ensuring that only authorized individuals gain access. Swing gates can also be integrated with access control systems but are generally more versatile, allowing for the passage of larger items, such as strollers or wheelchairs, making them more accessible. **Application:** Turnstiles are commonly used in high-security environments like stadiums, amusement parks, and public transport stations, where controlling and monitoring the flow of large crowds is essential.

In summary, the choice between turnstiles and swing gates depends on the specific needs of the facility, balancing security, accessibility, and user experience.

Turnstiles are generally not suitable for wheelchair access. Traditional turnstiles are designed to control pedestrian flow and prevent unauthorized entry, but their design inherently restricts access for individuals using wheelchairs. The rotating arms of a standard turnstile create a physical barrier that is difficult, if not impossible, for a wheelchair to navigate. For facilities that require both security and accessibility, alternative solutions are necessary. Accessible gates or doors, often located adjacent to turnstiles, are typically used to accommodate wheelchair users. These gates are wider and can be operated manually or automatically, allowing for easy passage. They are designed to comply with accessibility standards, such as the Americans with Disabilities Act (ADA) in the United States, which mandates that public spaces be accessible to individuals with disabilities. In addition to accommodating wheelchairs, these accessible gates can also serve other purposes, such as allowing entry for individuals with strollers, bicycles, or large luggage. They can be integrated with the same access control systems used for turnstiles, ensuring that security is maintained while providing necessary accessibility. In summary, while traditional turnstiles are not suitable for wheelchair access, facilities can implement accessible gates or doors to ensure compliance with accessibility standards and provide an inclusive environment for all individuals.

Swing gates accommodate strollers and wheelchairs by incorporating several design features that ensure accessibility and ease of use. Firstly, they are typically wider than standard gates, providing ample space for strollers and wheelchairs to pass through without difficulty. This extra width is crucial for maneuvering and ensures that users do not have to struggle with tight spaces. Secondly, swing gates often have a smooth, level threshold or no threshold at all, which eliminates any potential tripping hazards or obstacles that could impede the movement of wheels. This design consideration is essential for maintaining a seamless transition from one side of the gate to the other. Additionally, swing gates are equipped with user-friendly latching mechanisms that can be easily operated with one hand. This feature is particularly beneficial for caregivers or individuals who may need to hold onto a stroller or wheelchair while opening the gate. The latches are often positioned at a height that is accessible to both standing and seated users, ensuring that everyone can operate the gate independently. Moreover, many swing gates are designed to open in both directions, providing flexibility and convenience in various settings. This bidirectional opening capability allows users to choose the most suitable direction for entry or exit, depending on their specific needs and the surrounding environment.
