thresholds for walk in an experiment in Australia. If Next, the authors observed the distribution
a segment whose average speed was less than 6 km/h of speed characteristics of segments on foot (Figure
and maximum speed was less than 10 km/h, it was 4), by bike (Figure 5) and by motorized modes
likely to be on foot. They classified a segment as (Figure 6). Statistics of speed profiles were
bike if its average speed was under 40 km/h and the documented in Table 1. It can be seen that speeds of
biker came from a household having bicycle(s). In a walk and bike in Hanoi were significantly lower than
th
study in New York (US) [12], the 85 percentile of that in previous studies. For example, the maximum
speed of walk should not be over 6 km/h whilst bike speed of bike was less than 9 m/s (32.5 km/h) whilst
was out of scope. Safi et al. (2016) [18] labelled 75% of walking segments had the median speed
motorized if a segment had an average speed of over under 1.34 m/s (roughly 4.8 km/h). The speed levels
5.6 m/s along with an average acceleration of over of many motorized segments were similar to those

0.23 m/s . of bike.
