NDOT previews traffic-calming plan for Bay Cove Trail; residents press for circles and more radar signs
Summary
NDOT presented a preliminary traffic-calming plan for Bay Cove Trail after data showed an 80th‑percentile speed of 35 mph on a 25 mph street and roughly 1,200 vehicles per day. The plan includes speed cushions and radar feedback signs; residents urged traffic circles and treatments at a blind Rolling River intersection. A mailed ballot requiring 66% approval will decide vertical installations.

NDOT measured an 80th‑percentile speed of 35 miles per hour on a street posted at 25 mph and said the segment carries about 1,200 vehicles per day.
NDOT framed the program as an engineering‑focused effort to slow speeds on residential streets as part of the city’s safety goals. Burch said the program uses a five‑criteria prioritization (vehicle speeds 45% weight; volume 25%; non‑driver accommodations 15%; vulnerable‑user crashes 10%; trip destinations) to rank applications; the city has received more than 600 requests and selects about 25 streets each six months.
On performance, Burch cited before‑and‑after NDOT data from prior cushion installations showing average speed reductions (from 31 to 22 mph) and 80th‑percentile improvements (37 to 25 mph). On data collection she said NDOT used tube counters over 24‑hour periods this spring to record…
