VariablesDescriptions

Personal characteristics
GenderMale, 0; Female, 1
AgeEstimated age group: young (<30), 1; middle-aged (30-50), 2; elderly (>50), 3
Mode of transportationPedestrian, 1; bicycle, 2; electric bicycle, 3
DirectionThe direction which the people come from when the people arrives at the intersection: left, 1; right, 2; back, 3

Arriving behaviour & environmental conditions
Arrival phaseThe phase of motor vehicles: the left-turn light of the approach whose direction is same as the direction of observation group is green (close left turn), 1; the go straight light of the approach whose direction is vertical to the direction of observation group is green, 2; the left-turn light of the approach whose direction is vertical to the direction of observation group is green (far left turn), 3
Speed change upon arrivalThe people’s speed change when the people arrive at the intersection: slower, 1; faster, 2; unchanged, 3
Cross traffic volumeAverage volume crossing motor vehicles per lane per minute during the red-light phase of pedestrians and cyclists when the people arrive at the intersection (rank from small to large): low (0-25%), 1; medium (26%-75%), 2; high (76%-100%), 3
No. of people waiting upon arrivalThe number of other pedestrians who are waiting for the green light when the people arrive at the intersection
No. of people crossing upon arrivalThe number of other pedestrians who are crossing against the red light when the people arrive at the intersection
IRLR behaviourWhether to run the red light immediately when the people arrive at the intersection: no, 0; yes, 1
RLR behaviourWhether to run the red light: no, 0; yes, 1

traffic volume definition of low to high: the quartiles of cross traffic volume are selected as the threshold for low, medium, and high (upper quartile for high and medium; lower quartile for medium and low). The actual values ar: low (0-25%) (volume ≤ 85v/15min), 1; medium (26%-75%) (85v/15min ≤ volume ≤ 103v/15min), 2; high (volume ≥ 103v/15min 76%-100%), 3.
