Some thoughts:
- Eggert Rd (the smaller road with 7-8.5K daily traffic) could easily see a 4-to-3 road diet.
- While the two intersections with Eggert Rd could easily become roundabouts, they're too close to the Sheridan Dr/Niagara Falls Blvd intersection, so it would have to be an all-or-naught. I'm not certain that a roundabout is the right idea for that intersection.
- Sheridan especially is what I would alternatively call a "traffic sewer" or "retail hell". Way too many driveways and private access points for efficient traffic flow, and all those driveways add to the safety risk not just for bikes/pedestrians but drivers as well.
- Looking at the volumes along Sheridan and Niagara Falls, while upper 20s may seem high, its not out of the question for a 4-lane roadway. We have 4-lane roadways in suburban D.C. that handle mid-30s fairly well, even during rush hour. Especially on Sheridan to the east where there's a median, I think they could drop a lane without too much issue. The problem with using it for buses or bikes, though, is the aforementioned multitude of driveways.
