Thanks for your work regarding lowered speed limit in Cambridge. I live on Fresh Pond Parkway where the State Police do not enforce any traffic laws. The result is terrifying. Traffic is aggressive and moves at dangerously high speed. Despite a ban on trucks and buses, there is a lot of such heavy weight traffic in this residential,stretch generating vibration, noise and pollution. Your proposed speed reduction, with enforcement, would be a welcome first step in the right direction.
