1 ft = 0.3 m

Table Assumptions

Mode split is 55% adult bicyclists, 20% pedestrians, 10% runners, 10% in–line skaters, and 5% child bicyclists.

An equal number of trail users travel in each direction (the model uses a 50%/50% directional split).

Trail volume represents the actual number of users counted in the field (the model adjusts this volume based on a peak hour factor of 0.85).

Trail has a centerline.

Table Assumptions

Mode split is 75% adult bicyclists, 7.5% pedestrians, 7.5% runners, 5% in–line skaters, and 5% child bicyclists.

An equal number of trail users travel in each direction (the model uses a 50%/50% directional split).

Trail volume represents the actual number of users counted in the field (the model adjusts this volume based on a peak hour factor of 0.85).

Trail has a centerline.
