Abstract
A method and system is discussed for detecting distances between passengers walking onto escalators and moving sidewalks or travellators and for providing alerts to the passengers when minimum social distancing between the passengers is not being maintained.
Claims20
A method for ensuring social distancing on an escalator or travellator between a first passenger and a second passenger, the method comprising:
- a) detecting when the first passenger passes by a first motion detector disposed at an entrance of the escalator or travellator;
- b) calculating a time period it takes the first passenger to travel a predetermined distance required for social distancing on the escalator or travellator based on a velocity the escalator or travellator operates at, wherein the time period starts when the first passenger passes by the first motion detector;
- c) detecting when the second passenger passes by the first motion detector;
- and
- d) alerting the second passenger to stop and wait if the second passenger passes by the first motion detector before the time period expires.
