The data collected for this study reveals that the appropriate design user for shared use paths may vary with respect to design criteria or a facility design element. Table 23 shows design features, AASHTO design values for bicyclists, potential design users, and 85th percentile performance values.

It is worth noting that bicyclists (without trailers) do not appear as critical users for any of the design criteria. This is a major finding that may have a significant effect on how shared use paths and other components of the U.S. transportation system are designed, constructed, controlled, and maintained.
The data collected during this project suggest that several actions should be considered:
