Brookland Parkway Car Blockers
I count 10 intersections that the buffered bike lane crosses between Hermitage and Brook (both sides of the road).
I think a large concrete planter, clearly marked and made reflective, added to the buffer immediately after each intersection would go a LONG way toward educating drivers not to drive in the bike lane/forcing them to move to the travel lane as soon as they enter Brookland Parkway.
How much could that cost? Less than $10,000, I'd guess. And they could look cool.
Free concrete planters
These planters at Broad and Monroe will need to go once BRT come through—it's median running at that point. Let's put them on Brookland Parkway!
