Queues should be avoided, as the aisle areas between stands are usually areas designated purely for flows of people and have already been broadened by Koelnmesse in the planning of events.

Koelnmesse also recommends adding counters to stands for purposes of visitor processing. Accompanying measures can be used as well (e.g. scheduling appointments with customers).

Intervention may be necessary if Koelnmesse security staff notice queuing in aisles that restricts foot traffic.
