Pedestrian traffic flow can be constant or variable (e.g., employee entry or exit at specific times in a factory), planned or unplanned (e.g., system failure). When selecting the number of devices, the maximum pedestrian traffic flow should always be taken into account.

Typical types of pedestrian traffic flow:

  1. Low pedestrian traffic flow – occurs when the average number of people approaching a passage at the same time is no more than 1 person. There are no queues or bottlenecks. Simultaneous two-way traffic or the need for more than 2 people to move in one direction simultaneously occurs sporadically.
  2. Medium pedestrian traffic flow – occurs when the average number of people approaching a passage at the same time is no more than 2-3 people. Simultaneous two-way traffic or the need for more than 5-7 people to move in one direction simultaneously occurs sporadically.
  3. High pedestrian traffic flow – occurs when the average number of people approaching a passage at the same time is no more than 4-5 people. Simultaneous two-way traffic or the need for more than 8 people to move in one direction simultaneously occurs sporadically.
  4. Excessive pedestrian traffic flow – occurs when the average number of people approaching a passage is so high that it prevents efficient passage into the controlled zone and causes bottlenecks in front of the devices.
