I’m not sure what’s going on with the Central project, but thought this was a good piece to share given some concerns about the possible reduction in lanes (aka road diet) with whatever improvements come to Central.
For those unconvinced about road diets, according to a research study commissioned by the Department of Transportation in 2013, road diet are pretty successful in enhancing safety:
The most robust estimates range from 19 percent average reduction in total crashes on corridors in larger urban areas to 47 percent for more rural highways passing through small urban areas. Crash reductions have been documented for a range of conditions including highways passing through smaller localities, for corridors in larger urban/suburban areas, as well as intensively urban New York City.
The one caveat is that road diets don’t really work when streets are carrying in excess of 20,000 cars per day, but Central is not anywhere near that number and is lower than other arterial roads in Alameda.
