Description

Traffic control system, elevator system and method for controlling a traffic control system Technical Field The present invention relates generally to the field of traffic control. In particular, the invention relates to traffic control of elevators. Background Generally, door devices such as security doors and turnstiles may include traffic controls. The pass control allows only authorized users to pass through the door device. The pass control may be based on the use of a key card, a tag, an identification code, such as a Personal Identification Number (PIN) code, an ID number, and/or biometric techniques, such as fingerprint, facial recognition, iris recognition, retinal scan, voice recognition, etc. The door device may be communicatively coupled to the elevator system to enable an elevator call to be generated in response to the identification of an authorized user by the door device. Disclosure of Invention The following presents a simplified summary in order to provide a basic understanding of some aspects of various embodiments of the invention.
