“…See Table 1 for the upper limit of capacity in each region. Analyse the medical process and time-consuming situation of medical links in fever clinic, use agent social force model [13] , the pedestrian path and interaction characteristics of entering fever patients are simulated, coupling the computational fluid dynamics is used for modelling. If the interpersonal spacing is 1.5m, there is no queuing constraint, when the occupants reach theoretical upper limit, the physical model of fever clinic is shown in Fig 1.…”

Since the COVID-19 outbreak, high numbers of patients with respiratory symptoms flock to fever clinic, cause overcrowding. Due to relatively densely populated space and the existing ventilation strategy, lead to space environment bearing capacity lose efficacy. The patients in waiting space are faced a high risk of cross infection. Thus, it must be strictly controlling the personnel density and fresh air dilution level, prevent SARS-COV-2 transmission though aerosols. This study takes the fever clinic of 3A Grade Hospital case, based on the monitoring results of CO2 concentration and the transport of exhaled pathogenic aerosols, predict the waiting patient’s cross infection risk in crowded space. Computational fluid dynamics simulations and agent social force behaviour model were used. When the number of fever clinic reaches the upper limit of theoretical capacity, under the three ventilation types, average exposure risk in different areas of waiting space were studied. Results show that when the infector is located at the front of the waiting corridor (upwind direction of natural ventilation), when there is only natural ventilation, the difference of average intake fraction in the three areas of waiting space is small, that is, the correlation between distance and exposure is small. Our results also show that when ceiling air conditioner ventilation and natural ventilation are coupled, the dilution effect is significantly lower than that of natural ventilation in the front and rear area, and higher than only run mechanical ventilation.

“…Another area of research is how the patient evacuation priority order can be combined with the strategic arrangement of patients in healthcare facilities. For instance, Li et al (2020) [106] placed dependent elderly onto the lower floors of long-term care homes and independent elderly who could evacuate independently onto higher floors. Any dependent older adults prioritized for egress can be evacuated quickly given their proximity to ground level, allowing for quicker response times to aid semi-dependent or fully independent patients shortly thereafter.…”

The built environment continues to become increasingly accessible to people with disabilities, yet there remains a lack of focus on how these individuals are evacuated in emergencies. The objective of this scoping review was to survey the academic literature to identify solutions for safely evacuating individuals with functional limitations from the indoor built environment (i.e., buildings). Journal articles and conference proceedings published in the year 2002 onwards were included. Two pairs of reviewers independently evaluated 3562 articles from ten databases and identified 99 articles. The results were categorized into six main evacuation solution types: notification, wayfinding, egress, building design, strategy, and training programs. Our findings highlight the importance of tailoring solutions to the needs of individuals with different functional limitations. Future work should focus on expanding the number of solutions available for (1) emergencies beyond fires (e.g., natural disasters); (2) unique building types that may require specialized engineering considerations; and (3) a greater variety of impairments (e.g., seeing, hearing, cognitive). We also emphasize the need for more interdisciplinary work and the importance of including rescuers and rescuees in emergency preparedness discussions. These collaborations will ensure that building designs, organizational procedures, and evacuation aids complement each other to maximize safety. To our knowledge, this is the first scoping review to identify solutions for evacuating individuals with functional limitations from buildings. These findings may help inform future recommendations for new evacuation guidelines around the world.

“…MassMotion can also be used to model the movements of groups not of the average general public. A study was found where the evacuation of elderly was examined using MassMotion (Li, et al 2020). The study was interested in finding the impacts to evacuation times due to the distribution of dependent elderly in higher floors of a nursing home.…”

Airport Landside Vehicle Modelling and Pedestrian Behaviour Modelling for the Connected and Automated Era

This research examines the current state of the airport landside operations using microsimulation models to help understand how these areas will change with the introduction of connected and automated vehicles. Data collection from an existing North American commuter airport curbside was conducted to support this research. The curbside models provide comparisons of capacity and estimates of level of delay to travellers based on the different uses of space for the curbside. The analysis of the travellers' journey is explored further by following their path through the pedestrian access corridor between the curbside and the airport security. Data of pedestrian movement speeds and total travel time within the corridor were collected. This was modelled to understand the impact of dynamic changes to desired walking speeds. The combination of the collected data and models gives a complete overview of the airport travellers' journey between the curbside and airport security.iii Acknowledgements This research would not be possible without the support and help of individuals and organizations who provided necessary support and guidance.Thank you to the airport authority for providing access to the data allowing this thesis to be completed using real-world data. Without this access this thesis would not have the same practical scope.Thank you to members of both Carleton and York University for help with both the discussion behind the permission of the data acquisition and the collection itself. A special mention to Timothy Young for his many long trips between the two Universities during this process. That you to the scholarship providers who helped fund this research. Thank you to NSERC and OGS for providing external scholarships. Thank you to the Department of Civil and Environmental Engineering at Carleton University for providing internal scholarships and teaching assistant positions. Thank you to NSERC for the internship opportunity of the Summers of 2021 and 2022 through the TrustCAV program provided to me through the Principal Investigator Prof. F.
