Going Up?
As pointed out by TSYS School associate
professor of computer science Anastasia
Angelopoulou and her colleagues Konstantinos Mykoniatis of Auburn
University and Tianqi Gao Smith of the Mayo Clinic in their 2021 study
appearing in the International Journal of
Simulation and Process Modelling, pedestrian behavior in urban spaces has
abruptly changed amidst the COVID-19 pandemic due to government-issued
restrictions such as social distancing.
Although it is unclear whether pedestrian behavior will remain altered
and/or urban spaces will be changed accordingly post-pandemic, these
researchers take these changes and uncertainties, and the unique
characteristics of pedestrian traffic (as opposed to vehicle traffic), into
consideration in creating a hybrid simulation model that is capable of
examining the efficiency of several types of escalator pedestrian behaviors in various
non-crowded scenarios. According to
Angelopoulou, “our generic simulation model allows future users to evaluate the
efficiency of the escalator operation scenarios they would like to simulate by
providing output measures such as time spent in system and throughput and
allowing customizations of escalator dimensions and pedestrian-related
parameters based on user-specific requirements.” The researchers’ simulation, which employs the
AnyLogic simulation software, is useful for a number of scenarios, such as
emergent/evacuation vs. regular operation, capacity and number of available
escalators, escalator's dimensions (e.g., height and length) and speed, and
pedestrian preference (e.g., standing vs. walking).
