To cross a road successfully, individuals must coordinate their movements with moving vehicles. This paper describes use of a walking simulator in which people walk on a treadmill to intercept gaps between two moving vehicles in an immersive virtual environment. Virtual reality allows for a safe and ecologically varied investigation of gap crossing behavior. Manipulating the initial starting distance can further the understanding of a participant's speed regulation while approaching a gap. The speed profile may be assessed for various gap crossing variables, such as initial distance, vehicle size, and gap size. Each walking simulation results in a position/time series that can inform how velocity is adjusted differently depending on the gap characteristics. This methodology can be used by researchers investigating pedestrian behavior and behavioral dynamics while employing human participants in a safe and realistic setting.
为了成功过马路，个人必须使其动作与行驶的车辆相协调。本文描述了一种步行模拟器的使用，在这种模拟器中，人们在跑步机上行走，以便在沉浸式虚拟环境中拦截两辆行驶车辆之间的间隙。虚拟现实允许对间隙穿越行为进行安全且生态多样的研究。操纵初始起始距离可以进一步加深对参与者接近间隙时速度调节的理解。可以针对各种间隙穿越变量（如初始距离、车辆尺寸和间隙尺寸）评估速度剖面。每次步行模拟都会产生一个位置/时间序列，该序列可以说明速度如何根据间隙特征进行不同的调整。研究人员在安全且现实的环境中使用人类参与者时，可以采用这种方法来研究行人行为和行为动力学。
