  1. Posted limits are safest and tend to produce the fewest crashes when set at the 85th percentile speed of free flowing traffic under good conditions, rounded to the nearest 5 mph interval. The existing 30 mph limit is set at the 0th percentile speed with no one in compliance under good conditions – and that is both illegal and total nonsense under Caltrans good rules. No area has 100% of the drivers driving dangerously for the conditions. It is likely that any enforcement actions raise the crash risks by disturbing the flow in the area, and subjecting both the officer and the passengers in the vehicle to higher risks of being in a crash.

    If 85% of the drivers are at or under 33 to 37 mph, the safest limit to post would be 35 mph. If 85% are at or under 38 to 42 mph, then 40 would be the safest limit. The survey already shows that posting a limit well below the actual travel speeds has NO effect, because drivers will not comply with unrealistically low and arbitrary speed limits set lower than necessary for the conditions. Ms. Dutra’s comment “You don’t orchestrate human environments by a mathematical chart.” is true — the DRIVERS orchestrate the environments by their behavior and 100% of them deem the 30 limit to be wrong. Caltrans must change it.

  2. Keep it at 30 mph or lower it. The speed limit for residential neighborhoods is 35. Put up an electronic sign, like they have for Laytonville, stating how fast the vehicle is moving. The people in the town have a right to shop and park safely in their own town.
