Table 3: The boarding and alighting times in Scenario 1 without markings on the floor. Figure 6: Scenarios at the laboratory experiments: (**a**) Scenario 1 without markings on the floor for boarding and alighting; (**b**) Scenario 2 with markings on the floor for boarding and alighting. However, the Level of Service (LOS) was measured in both scenarios, in which Scenario 1 presented a LOS of C compared to Scenario 2 with a LOS of B. It is important to highlight that the improvement of the LOS could bring more accessibility for those passengers boarding and alighting, which is in line with the literature review. In addition, a survey was conducted with participants of the experiment, where they were asked about their comfort level regarding accessibility in both scenarios. The survey was conducted with the following questions:  
1. Age;
2. Gender;
3. Number of days you use the metro;
4. Scenario 1: Based on the experiment, how was your experience on a scale from 1 to 5? With 1 being very uncomfortable and 5 being very comfortable;
5. Scenario 2: Based on the experiment, how was your experience on a scale from 1 to 5? With 1 being very uncomfortable and 5 being very comfortable. Questions 4 and 5, related to the experience in Scenarios 1 and 2, respectively, are intended to assess the level of satisfaction, which corresponds to how participants feel about the laboratory experience. As a result of the survey, 77% reported being 18 years old, while the rest recorded an age older than this. Meanwhile, 73% were men and 22% were women. Most of the participants used the metro frequently (e.g., more than 3 days a week). Figure 7 shows the results of questions 4 and 5, where a clear preference for Scenario 2 is observed, which recorded a higher number of responses in the \"comfortable\" and \"very comfortable\" levels. \begin{table}

Table 4: The boarding and alighting times in Scenario 2 with markings on the floor. Subsequently, within the survey, participants were asked to respond to two open-ended questions. The first question was: \"Have you noticed any obstacles or problems when boarding or alighting from the metro? If so, could you describe them?\" The second question asked: \"How could you improve the travel experience from the design of these spaces?\". For the first question, the participants' responses were distributed as follows: 7 people identified issues related to \"Accessibility\", 16 people identified issues related to \"Time\", 6 people identified issues related to \"Space\", 28 people identified issues related to \"Time\" again, and finally, 4 people identified issues related to \"Signage\". Regarding the second question, the participants' responses were distributed as follows: 13 people would like improvements related to \"Space\", 16 people would like improvements related to \"Layout\", 4 people would like improvements related to \"Time\", 8 people would like improvements related to \"Infrastructure\", and finally, 11 people would like improvements related to \"Other types\", referring to teaching people how to behave in pedestrian transit spaces.
