“…The result of [36] shows that θ had a relatively minor impact on the exit choice compared with NCE and DIST. This study shared similarities with the scenario presented in [36]. Both studies involved decisionmaking in a rectangular room with multiple exits, where exit visibility and pedestrian distribution influenced the choices.…”

“…The logit model was implemented in numerous numerical evacuation studies to simulate and depict individual behaviour in different scenarios [3,30,[34][35][36]. The model typically operates on the assumption that individuals are inclined to choose the option that yields the highest benefit or utility [37,38].…”

“…It is noteworthy, however, that other studies proposed alternative implementations of the multinomial logit model. For instance, Gao et al [36] replaced the expected utility theory with the cumulative prospect theory [41] and accentuation of differences [42] to accentuate the influence of context effects on exit choice. In their study, a power value function was used to transform the risk assessment attitude of the decision-maker into one that was more subjective-oriented:…”

This study investigated the interplay between exit selection models and local pedestrian movement patterns within floor field frameworks. Specifically, this investigation analysed the performance of a multinomial logit exit choice model, incorporating both expected utility theory and cumulative prospect theory frameworks when coupled with three distinct local-level pedestrian movement models (FF-Von Neumann, FF-Moore, and NSFF). The expected utility theory framework considers the deterministic component as a linear relationship, while the cumulative prospect theory framework further considers the decision-maker’s risky attitudes by transforming objective terms into subjective terms using a power value function. The core objective was to comprehend how local movement dynamics, as represented by the floor field models, influence decision-making during exit selection. Comparative analyses revealed intriguing variations between the three local models, despite their shared expected utility theory-based exit choice framework. These discrepancies stemmed from the diverse pedestrian trajectory behaviours generated by each model. Consequently, these local dynamics impacted the decision-maker’s assessment of critical factors, such as the number of evacuees close to the decision-maker (NCDM) and the number of evacuees close to an exit (NCE), which the exit choice model incorporates. These assessments, in turn, significantly affected higher-level decision-making. The integration of the three models with the multinomial logit exit choice model, using either cumulative prospect theory and expected utility theory frameworks, further strengthened the observed bilateral relationship. While the specific nature of this relationship varied depending on the chosen framework and its implementation details, these consistent findings demonstrate the robustness of the results. This reinforced the influence of local-level pedestrian dynamics on higher-level exit selection, highlighting the importance of accurate crowd dynamics modelling, especially when advanced exit choice models consider local movement factors.
