From a standpoint of transportation efficiency on forest roads, the author discusses speed difference between on gravel surface roads and on asphalt paved roads with the theoretical value from a braking distance, and the results from a survey of the running speed at the down-grade section on forest road. To improve transportation efficiency, it is desirable to pave forest roads with asphalt not only at the gentle grade section but also at the steep grade section.
