| Abstract This study explored the influence of different information sources and environmental cues on decision-making behaviour at route intersections during flood evacuation. The information sources included traffic police officers, navigation systems, and road signs. The environmental cues involved floodwater on the streets and congestion. The talk-through method developed by Lawson (2011) was employed, in which participants were presented with hypothetical flood scenarios and asked to explain how they would respond. The results showed that receiving routing directions from a traffic police officer to follow the planned route increased the likelihood of complying with the instructions and staying on the planned route the most. In contrast, observing floodwater along the planned route was the strongest factor in decreasing the likelihood of staying on it and switching to an alternative route. Following a within-subject design, these findings were based on nonparametric statistical analysis, in which the Friedman test and the Wilcoxon Signed-Rank test assessed differences in participants’ rating scores across conditions. This research makes an important contribution to understanding how information sources and environmental conditions influence decision-making during floods. |
