# Research on the Evacuation Characteristics of Cruise Ship Passengers in Multi-Scenarios
## 4 Discussion of Simulation Results
### The Analysis of the First 10% and Last 10% of Arriving Passengers
For type 1, 2, 6, and 7 passengers with a fast walking speed, some of them are in the last 10% of arrivals under the night scenarios. The reasons for this phenomenon are analyzed by combining the types and initial positions of passengers. Figure 12 shows the initial positions of types 4, 5, 9, and 10 of the first 10% of arriving passengers under the night scenario, and types 1, 2, 6, and 7 of the last 10% of arriving passengers under the night scenario can be seen in Figure 13. As can be seen from these figures, most type 4, 5, 9, and 10 passengers are distributed on Decks 3, 4, and 5. For type 1, 2, 6, and 7 passengers, they are mainly distributed on decks that are higher than Deck 5. In addition, the first 10% of arriving passengers are mainly located in MVZ 2, 3, and 4. The last 10% of arriving passengers are mainly in the two MVZs near the bow and stern. Further analysis is conducted through the initial MVZs where these passengers are located. As shown in Figure 14, the proportion of types 4, 5, 9, and 10 of the first 10% of arriving passengers in MVZ 1 and 5 is low. The proportion in MVZ 5 is not more than 20%, and the proportion in MVZ 1 does not exceed 10%. From the previous analysis, the evacuation efficiency of passengers in these two MVZs is low due to the distribution of staircases. Therefore, more than 70% of these passengers are distributed in the MVZ 2-5 area. Although the walking speeds of these four types of passengers are slow, they may \begin{table}

In the individual scenario of Figure 15a, the proportion of types 1, 6, and 7 of the last 10% of arriving passengers are almost over 80% in MVZ 5, and over 10% in MVZ 1. In the group scenario of Figure 15b, the proportions of the four types of passengers in MVZ 5 are also more than 60%, and the proportions in MVZ 1 are nearly 20%. For these four types of passengers under both scenarios, the sum of proportions of MVZ 1 and 5 is more than 80%. It can be seen that although these four types of passengers move fast, they may also arrive at the embarkation area in the final stage of evacuation if their initial position is distributed on a higher deck or in the MVZs near the bow and stern.
