Item 2.11 Designation of Safety Corridors has my enthusiastic support. This is an important, legally- required stepping stone towards reducing speeds AND speed limits on our high-injury corridors.
After this Resolution is passed, I implore DOT to prioritize implementing Assembly Bill 43 (2021) and Assembly Bill 1938 (2022) to their fullest extent, on Safety Corridors AND roads with "high concentrations of bicyclists or pedestrians" [1]. This authority to lower speed limits also pairs well with the Speed Safety System Pilot Program.
I'd also like to expand on this point in the Staff Memorandum:
a possible reduction of the posted speed limit by an additional 5 miles per hour. (emphasis mine)
https://safetrec.berkeley.edu/tools/california-safe-speeds-toolkit/california-safe-speeds-toolkit- current-speed-limit-setting-law explains AB 43 better than I could. But, roughly speaking, AB 43 allows speed limit reductions, potentially as much as 10 MPH reduction:
By default, the speed limit is set by measuring the p85 traffic speed, and rounding to the nearest 5 MPH increment.
ANY speed limit that would've been rounded up, may be rounded down instead. For example, if the p85 speed is 43 mph, the speed limit can be set to 40 mph instead of 45 mph.
Any speed limit that must be rounded down, can be decreased by 5 mph if certain conditions and declarations are met. For example, if the p85 speed is 42 mph, the speed limit can be set to 40 mph or potentially 35 mph.
Speed limits on ANY designated Safety Corridor or roads with "high concentrations of bicyclists or pedestrians" can be reduced by 5 mph, independently of the above.
The Council action today enables the 5 mph decrease on the designated Safety Corridors. But I urge Council and DOT to implement the rounding down of speed limits on our Safety Corridors, Vision Zero PSCs, bicycle network, and high-pedestrian areas. And I urge Council and DOT to also implement the 5 mph decreases on roads with "high concentrations of bicyclists or pedestrians" that aren't Safety Corridors.
