On the road diet again

Filed under: Alameda — Lauren Do @ 6:02 am

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.

  1. I just came back from Park Street area and Central was already backed up several blocks, which caused people to turn down residential streets to get to Santa Clara, or Lincoln, so in essence you push traffic off Central and onto the side streets which are not designed for a lot of traffic. I cut over on Walnut? which you just about have to pull over on the sidewalk to let a car come through coming the other direction. In my point of view road diets only work to a point and can be carried to far. You push the traffic off one street it just goes to another street.

  2. 1. Jake, your anecdote is confusing at best. You drive the East end of Central often? I frequently exit Alameda in the morning at peak traffic around 8-9 and there is often traffic on Park from Buena Vista, but side arteries above Buena Vista, including Central seldom if ever have more than three or four cars trying to turn left east bound. If there was a traffic anomaly like an accident that doesn’t mean much.

    I don’t recognize your description at all.

  3. Jake, this project is proposed for a 4 lane Central WEST of Sherman st. You are talking about morning commute traffic on a two lane Central near Park St. Your comment could not be more irrelevant to the topic at hand.
