Safety Prediction Model for Freeway Facilities with High Occupancy Lanes
In an effort to relieve highway congestion and promote the movement of people, some state departments
of transportation have modified their freeway facilities to include high occupancy vehicle lanes, high occupancy toll lanes (HOT, or HO lanes), and other managed
lane strategies.
NCHRP Web-Only Document 387: Safety Prediction Model for Freeway Facilities with High Occupancy Lanes,
from TRB's National Cooperative Highway Research Program,
fulfills an analytical gap, providing a safety prediction methodology specifically for freeway
facilities with HO lanes and provides a stand-alone approach by using one-direction models
for freeway segments, entrance speed-change lanes, and exit speed-change lanes.

Safety Implementation Guide, and a
Safety Prediction Model Presentation.
