This paper focuses on the findings on pedestrian free speeds. Table 1 shows pedestrian free speeds found in literature. Both the average free speed and the variance (if available) are shown, as well as the country where the study has been performed. 37 m/s. The standard deviation has been calculated as a mean of the free speeds in Table 1 using the co-efficient of variance. Weidmann (3) performed a literature study on pedestrian speeds in 1993. 6 m/s in Table 1). Under specific circumstances, the normal distribution can have a positive skewness.
