Assessing Part-time Shoulder Use Safety. Assessment of the safety impacts of part-time shoulder use on a given facility should begin with a review of three or more years of historical crash data. The review should consider the crash type, temporal factors (e.g., time of day, day of week), and location. Best Practices for Planning and Design of Freeway Facilities Summary.
