16. Abstract Dynamic part-time shoulder use (D-PTSU) opens shoulders for travel beyond fixed (or static) time periods (e.g., weekday peak periods). Dynamically operating the transportation system by matching supply-side strategies in accordance with prevailing conditions and travel demands represents an important advancement in agency adoption of Active Transportation and Demand Management (ATDM) concepts. This report provides agencies with relevant information and best practices for operating D-PTSU on freeways. The report explains how the opening of PTSU can be optimized based on speed and volume conditions observed or modeled on the freeway. Methods for determining specific "decision parameters" for opening the shoulder are presented. The report also assists agencies in determining if D-PTSU is an appropriate strategy where no part-time shoulder use is in place, or where static part-time shoulder use is in place. |
