With apologies in advance to those people who find my articles and/or comments too detailed, I’m going to clearly show David Greenwald of the Davis Vanguard the numbers, so that he, and hopefully everyone, understands the traffic study contents.
For those of you who want to skip the detail and just read the summary, it appears at the bottom of the article alongside the very tall Google Earth image of Mace and its current lane configuration.
With the caveat that the readers of yesterday’s article don’t know what steps might have happened behind the scenes that weren’t described in the article, it appears that yesterday, David Greenwald forgot to follow his own advice. Several times in the recent past David has complained bitterly that one of the Vanguard’s guest writers published their article without taking the time to check with an information source prior to publishing an article that criticizes one or more aspects of our community’s decisions and/or decision processes. I believe, but could be wrong if there is information I don’t know about, David would have done well for himself and for the Yes On Measure H campaign team if he had checked with the information source he criticized in yesterday’s article. If he did do so, I’m sure he will clarify in a comment.
Traffic studies are arcane beasts. They follow a set of clearly set out rules that a lay person like David and me has to work hard to understand. It is easy for a lay person to make mistakes when trying to understand “WHY?” a traffic finding in the traffic study is what it is. In late 2020 when formally submitting questions about the traffic study in the Draft EIR, I learned that lesson the hard way. To their credit Fehr & Peers responded very clearly, logically, understandably, and professionally to my questions … pointing out where I had gone wrong in my calculations. They were good teachers. I thank them for that educational lesson.
So, when the updated traffic study for DiSC 2022 was published I was able to much better understand the data … and also carry forward the intersection by intersection graphics that had accompanied the 2020 traffic study. However, before I finalized any conclusions based on the new data, I reviewed those tentative conclusions with a retired City traffic engineer and two engineering professionals who have considerable experience dealing with traffic. Their collective and individual counsel was very valuable. Their advice would have been very helpful to David if he had sought that advice prior to publishing yesterday.
