• type and condition of road surface
• road width
• sight distance and traffic volume.
Tables 2 and 3 and Appendix 2 can be used to determine appropriate travel
speeds and stopping and sight distance requirements along the road and at
road junctions.
Turnouts should be located in suitable numbers (intervisible and often three
or more per kilometre) on single-lane roads to accommodate user safety. The
recommended lengths and taper widths for turnouts, based on stabilized road
width, can be determined from Table 4.
The Manual of Geometric Design Standards for Canadian Roads, published
by the Roads and Transportation Association of Canada (RTAC) provides
design standards that can be used for forest roads.
