Abstract：In order to investigate the rate of influence of various types of eye-movement data on the duration of cognitive decisions made by subjects located at forks in the road or during turnbacks during wayfinding in emergency shelters,In this paper,we used the regression-based Shapley value decomposition to find the con-tribution of first gaze duration,total gaze duration,number of gaze points,and sweep duration,respectively.The results show that:the contribution rate of the number of gaze points is 32.32%,which is an important factor;the contribution rate of the total duration of gaze is 29.23%,which is a second important factor;the contribution rate of the duration of the first gaze and the length of sweeping is 12.76%and 25.69%,respec-tively,which are both second important factors.The conclusion of this study can provide data support and theoretical reference for the distribution design of emergency shelter signs at key nodes such as road junc-tions.
