Abstract

A cracking rate was calculated from the video by the video camera with the road surface property of the Tamagawa cycling course by the machine learning method. The cracking rate measurement distance accounted for 26.4% of 18.2km in total length of the Tamagawa cycling course at 4.8km.

Cr = 100% were mixed with cracking rate Cr = 60% at width 2.0m with crazing rate Cr = 0% at width 3.0m.

Right-side gap rate RGr of a bicycle run and the walker was measured by the video measurement of the traffic state.

Right-side gap rate RGr was 70%±5% without depending on width in the case of an independent bicycle run, walk.

On the other hand, a right-side gap rate decreased so that cracking rate Cr increased in width 2.0m by the two-way traffic and was RGr25% - 38%.

right side gap rate RGr was 35% - 50% at width 3.0m.

In addition, the acceleration of the Z-axis direction increased so that cracking rate Cr increased, and the maximum of the Z-axis acceleration was 75.5m/s2 in 25km/h per an hour, crazing rate Cr = 100%.
