Council debates Route 99 speed limits after police study shows 85th‑percentile at 47 mph

Council members debated whether to alter posted speed limits on Route 99 after the police department presented short‑term speed monitoring and crash data. The police chief (identified in the meeting) said a four‑day speed sample captured 3,381 vehicles with a highest recorded speed of 59 mph, an average (50th percentile) of 41 mph and an 85th‑percentile speed of 47 mph. "The highest rate of speed was 59 miles an hour...the average speed was 41...the 85th percentile is 47 miles an hour," the chief said.

Staff and council members discussed the sequence of posted limits—55 mph outside the county, stepping down to 45 mph and dropping to 35 mph just before a sharp turn near the bike park—and whether the posted transition points recommended by VDOT are appropriate. One council member argued that raising the posted limit to 45 mph in a segment would likely increase typical driving speeds to 55–60 mph, citing the 85th‑percentile data and highway safety research that motorists naturally exceed posted limits.

Others said the current placement of the 35‑mph sign creates a "bad look" when residents are ticketed immediately upon entering town and suggested moving or adding transition signage, flashing speed signs, or asking mapping providers to update posted limits to reduce GPS‑based confusion. Staff offered to provide further data on citations and to explore engineering solutions including portable flashing speed advisories and working with VDOT or map providers to correct posted limits on navigation apps.

No ordinance change was enacted; council asked staff and the police to gather additional data and potential engineering remedies for future consideration.
