Our preliminary analysis of the intersection indicates that a right-turn lane on eastbound Cornell Road onto southbound Barnes Road would:
- Reduce congestion significantly and enhance mobility.
- Improve safety and reduce crashes. (Up to 30% of crashes on Cornell Road occur in eastbound congestion.)
- Reduce vehicle backup west of Murray Boulevard (eastbound traffic) during the afternoon/evening rush hour.
- Provide additional cyclist protection from vehicles turning right.
- Potentially reduce traffic cutting through neighborhoods to avoid congestion on Cornell Road.
- Improve TriMet bus service reliability.
An eastbound turn lane also would:
- Eliminate one block of on-street parking and the curb extension on the south side of Cornell Road (west of Barnes Road).
- Add bicycle-vehicle weaving challenge for cyclists navigating the new right-turn lane.
- Require possible relocation of the bus stop on the south side of Cornell Road, west of the intersection.
- Impact utilities, resulting in cost and construction impacts.
- Require possible reconstruction of the traffic signal, resulting in cost and construction impacts.
- Result in increased pedestrian crossing distance.
