Figure 7 shows the effects of 'number of pedestrian crossings' and 'length' on the
85
th
percentile speed for weekday model. As indicated in the figure, the 'length' vari-
able is positively correlated with the 85
th
percentile speed. On the other hand, the
'number of pedestrian crossings' is negatively correlated with the 85
th
percentile
speed. The highest 85
th
percentile speed (71.50 km/hr) is found for highest 'length'
(2.9 km) and least 'number of pedestrian crossings' (0-1).
