"While crash frequency and severity did correlate with higher speeds, the most statistically reliable trends that emerged had nothing to do with property damage or personal injury. It was enforcement outcomes that were most demonstratively impacted. In other words, when speed limits go up, fewer people get tickets; when they go down, the opposite happens."
@benfulton this is a bad take and the Capitol highway example is a bad design, that doesn't serve bikes nearly as well as the article implies, partly due to the oversized carway design. Also it's been open for one month, surprising to see any study try to draw conclusions there.
Automated enforcement should be tied to mandatory redesign if we see too many tickets, & PBOT definitely botched this $26M boondoggle, but this author is just yet another driver who doesn't want to be held accountable.
@benfulton "85th percentile speed is the average speed at which 85% of drivers travel on a given stretch of road (or one just like it, for the purposes of new construction)."
The article makes some good points, but that is actually incorrect.
@benfulton "If the city simply adhered to the 85th percentile rule and raised the limit back to 35 mph, citations should return to normal (something AAA's study actually established to a statistically significant degree) without any detriment to driver, pedestrian or cyclist safety."
And more importantly, this is not supported by the case. It's not true that cyclists and pedestrians are just as safe when people are driving 35mph around them, even if they have bike lanes and sidewalks.
@capntransit@benfulton how anyone can draw any conclusions from citations on one mile of Portland street that's been half closed for two years and only complete for a month, besides our police bureau politicizing traffic citations 🙃 and they never cite for less than 12mph over anyway. Statistically significant my foot.
