New Beaverton-Hillsdale / Scholls Ferry Intersection

The worst aspect of the existing alignment is that the intersection angle is so acute that BH Highway drivers must turn almost 180 degrees to see traffic from the left. For pedestrians and cyclists like myself, the very long crosswalks (interrupted by steep traffic islands) are a car-dodging death trap.
Ideally, Scholls Ferry should cross Beaverton Hillsdale at a 90 degree intersection, but the diagonal kink in BH makes that impossible.
However, the older plan can be improved greatly, changing a 30 degree intersection into a 70 degree intersection, by rerouting Scholls Ferry EASTWARD through the current location of the abandoned Safeway and, moving the main crossing two blocks to the east, rather than an added slalom through the lumberyard. With the new plan, Oleson no longer terminates directly at BH highway, but to the re-aligned Scholls Ferry, four hundred feet to the south.
Besides the new crossing light and the new Oleson/Scholls light, this shows three more lights near the main crossing:
- Dogwood Lane to the west, crossing Beaverton Hillsdale Highway
- Hamilton to the north, a tee at Scholls Ferry road
- 62th street to the east, a tee at at Beaverton Hillsdale Highway
These lights, plus the light at 78th to the west and Oleson/Scholls to the south, will all be synchronized with traffic cams and a smart controller - the purpose is to modify traffic flows on the major streets so that the east-west and north-south platoons synchronize at the crossing. This can greatly reduce "interference" and increase the flow through that intersection; most drivers will not even need to stop.
Why a light at Dogwood? Besides synchronization, that light can be the only entrance and exit point for the new retail areas north and south. Eliminating driveways will increase safety after traffic moves faster.
Why a light at Hamilton? Besides synchronization, that will help Trimet 55-Hamilton buses turn at that corner. Smoother bus service, more riders, fewer cars.
Why a light at 62nd? Besides synchronization, that connects to the recently expanded Robison Health Center, and a lot of new senior housing to the south. Those seniors will use transit (hopefully) and drive cars unsafely (probably). Faster Beaverton-Hillsdale traffic (hopefully) will lead to more turn-related accidents (probably).
