Table 1 Coding information description for each fixation
From: Pedestrian gaze pattern before crossing road in a naturalistic traffic setting
Coding categories | Explanation |
|---|---|
Trial ID | Identify which decision-making trial the fixation belongs to; |
Target ID | Identify the gazed target; |
Target type | Record the type of the gazed object; motor vehicle = 0; Non-motor vehicle = 1; Other road elements = 2 |
Dist_Longitudinal | The actual longitudinal distance of the fixation |
Dist_transverse | The actual transverse distance of fixation |
Gaze duration | Duration of the fixation recorded by eye-tracker |
Vehicle size | Normal = 0 (like sedan and taxi); big = 1 (like bus and truck) |
Vehicle type | Divided by vehicle function; Car = 0; bus = 1; taxi = 2 |
Vehicle color | White and silver = 0; black = 1; green = 2; yellow = 3; red = 4; blue = 5 |
Vehicle components | We divided vehicles into 12 different components. Figure 3 shows these components |
