Going in reverse order from when these things came over the transom:
POINT THE FIRST
“25 keeps us all alive!” — To be clear, I do not believe this is really the slogan, but I was in New York over the past weekend and snapped this picture:
You’re reading the sign right. New York has had a city-wide 25 mph speed limit for more than a year now. The world has not ended and their economy has not crashed, but traffic fatalities of all kinds of down year over year: 241 this year against 269 last year. The new Boston Vision Zero Action Plan is finally pointing us in this direction. But let’s be honest: it is long, long past time for our city to take the same kind of step — let’s make 2016 the year it happens.
POINT THE SECOND
Why 9 or 10 is better than 12. I commend to everyone the following article from Rob Steuteville over at Better Cities & Towns about how the humble Williamsburg Bridge’s rehabilitation back during your correspondent’s youthful years in the big city led to some of the first research into why narrower vehicle travel lanes are safer than wider ones. Worth a read: The New Science of Traffic Engineering. Challenging a misguided orthodoxy only sticks when you gather the data to show why that orthodoxy is wrong.
