The COVID-19 pandemic globally affected the complete transport sector
and especially passenger air transport with nosediving traffic numbers,
wide-ranging travel restrictions and long-lasting uncertainties (see IATA,
2020). As air travel starts to recover cautiously from severe losses of
traffic volumes over the pre-pandemic year 2019 and travel restrictions are
relaxing, air transport providers have to ensure that passengers as well as
people working within the air transport sector will remain safe and be
prepared for the next Pandemic. For Example, arboviruses have the potential
to spark the next epidemic, warns the World Health Organisation (WHO) and it
might only be a question of time when the next pandemic will rise. Airports
need to prepare to cope with the next pandemic efficiently and effectively.
For this purpose, we develop a toolbox to analyse and evaluate operational
measures along the process chain of travelling at an airport.This paper
examines the contamination risks at airports covering the travel process
from security checks to aircraft seat. In our study we examine the
possibility of an infection by dint of simulation with the Pandemic
Simulation Model (Pandemic SiM). For this purpose, we advanced an earlier
version of Pandemic SiM that only covered the security check area by adding
typical boarding processes of a medium sized European airport. The model is
based on a real European airport serving around 12 million passengers per
year (in 2019). The simulation model incorporates a new algorithm
calculating the probability of spreading a virus (like COVID-19) via
droplet, airborne or contact transmission during different airport travel
processes along the travel chain. The algorithm considers different
infection situations and incidence values and allows for a quantification of
infection risks per individual simulated passenger. Based on the output of
the simulations of the process chain in combination with that algorithm we
can show the effectiveness of measures like social distancing and their
consequences to minimize contamination risks along travel processes at
airports. The paper describes the modelling, the algorithm to calculate
contamination risks, as well as results and findings of the simulation runs.
It will show how contamination risks, capacity, waiting times and waiting
space are affected. This will provide airport operators with decision
support for challenges arising from the need to be prepared for the next
pandemic.
