Railway stations and metros are one of the busiest, bustling areas, especially those located in the heart of the city. Such locations are also open to the public, which means that there will most definitely be a large number of people frequenting it and human traffic may be denser during peak hours. As such, traffic and access control is vital. The implementation of access control systems will also help to keep the traffic subdued and allow people to make their entries and exits in an orderly fashion. Besides that, video surveillance also helps to heighten security, allowing security personnel to keep watch at all times, indirectly reducing possible crimes such as pickpocketing and thievery. And, as with large spaces that are open to the public, there will be a need to install fire exits and emergency escape hatches where necessary, in case of a fire or any other form of emergency.
