Modelling people's behaviour is a complex task, not only because of their intrinsic complexity but also because of their interaction with the environment and other individuals. The traditional format for discrete choice experiments involves the use of text and images. However, there is a growing tendency for using tools that offer a more realistic representation of complex and dynamic attributes in discrete choice experiments. The Virtual Immersive Reality Environment (VIRE) emerges as a resource for a better understanding and presentation of variables that are difficult to understand using text-only experiments. Despite its advantages, VIRE experiments are costly and have additional complications in their practical use. This study aims to analyse the benefits of using VIRE in discrete choice modelling, comparing with the traditional text-only format with image surveys in two contexts. The first context considers the study of pedestrian behaviour when choosing alternatives for crossing an urban street. The second context deals with the behaviour of people during an emergency exit situation inside a covered sports arena. The results suggest that the assisted use of VIRE allows respondents to perceive environmental dynamics better than traditional choice experiments. VIRE adds realism and seems to improve a respondent's cognitive understanding of complex elements in the environment created by the modeller.

对人们的行为进行建模是一项复杂的任务，这不仅是因为其内在的复杂性，而且还因为他们与环境和其他个人的互动。离散选择实验的传统格式涉及文本和图像的使用。但是，在离散选择实验中，使用能够更真实地表示复杂和动态属性的工具的趋势正在增长。虚拟沉浸式现实环境（VIRE）成为一种资源，可以更好地理解和呈现使用纯文本实验难以理解的变量。尽管具有优势，但VIRE实验的成本很高，并且在实际使用中还会带来其他复杂情况。这项研究旨在分析在离散选择建模中使用VIRE的好处，与传统的纯文本格式进行比较，并在两种情况下进行了图像调查。第一种情况考虑了在选择穿越城市街道的替代方案时对行人行为的研究。第二种情况涉及在有盖体育馆内紧急出口情况下的人的行为。结果表明，VIRE的辅助使用使受访者比传统选择实验更好地感知环境动力学。VIRE增加了真实感，似乎可以提高受访者对建模者创建的环境中复杂元素的认知理解。第二种情况涉及在有盖体育馆内紧急出口情况下的人的行为。结果表明，VIRE的辅助使用使受访者比传统选择实验更好地感知环境动力学。VIRE增加了真实感，似乎可以改善受访者对建模者创建的环境中复杂元素的认知理解。第二种情况涉及在有盖体育馆内紧急出口情况下的人的行为。结果表明，VIRE的辅助使用使受访者比传统选择实验更好地感知环境动力学。VIRE增加了真实感，似乎可以提高受访者对建模者创建的环境中复杂元素的认知理解。
