<br />Attachment A - Corridor Congestion Summary <br /> <br />Sub-corridor <br /> <br />AM AM PM PM <br />Northbound Southbound Northbound Southbound <br /> <br />1. Beltline to North TMA boundary <br />2. Franklin to Beltline <br />3. 30th Ave to Franklin <br />4. South TMA boundary to 30th Ave <br /> <br /> <br />Interstate 1-105/0R126 E <br /> <br />This roadway carries a substantial amount of mobility dependent travel. In the AM <br />period, the three westbound sub-corridors from Main to 1-5 have the highest mobility <br />dependent score following Interstate-5 and the River Rd to Oelta Hwy sub-corridor of <br />Beltline Highway. Mobility dependent trips constitute 71-940/0 of the volume on this <br />faci I ity. <br /> <br />The current OHP mobility standard is 0.8. <br /> <br />This corridor exhibits a strong AM/PM directional split (heavy west-bound in the <br />morning, heavy east bound in the evening). <br /> <br />2002: <br />Based on the VMT weighted V/C ratio for each sub-corridor, the facility meets the <br />performance standards of the OHP. Some small stretches of this facility fail the <br />standard by a large degree including 1-105 at 1-5, and the Washington/Jefferson <br />Bridge crossing north of the river. <br /> <br />2025: <br />Under the 2025 RTP- Financially Constrained scenario, and based on a VMT <br />weighted average V/C for the daily peak period, the eastbound 1-5 to Pioneer <br />Parkway sub-corridor is the only sub-corridor that will not meet the OHP standard. <br /> <br />The table below examines the V/C results for the AM and PM periods of the 2025 <br />RTP- Financially Constrained scenario where the ~ mark indicates compliance with <br />the standard on a V/C weighted corridor basis but with a segment failure within the <br />sub-corridor indicated by *: <br /> <br />Sub-corridor <br /> <br />AM AM PM PM <br />Eastbound Westbound Eastbound Westbound <br /> <br />1.
