The article was great! Engineering is nothing but tradeoffs.

Just replied to them to point out that LOS actually is defined objectively because I saw the “junk science” framing as kind of sidestepping the real issue – optimizing for too good, as you say.

Your post implied that the underlying concept of ped LOS is “entirely subjective”, and that “junk science” leads to bad design standards like these.

That’s not right – the reference objectively defines ped LOS and tasks the designer with sizing the platform to achieve the selected LOS.

Pedestrian LOS is not “entirely subjective”. It only “seems to be” that way if you don’t even bother looking into the sources that are cited right there in the text.

Pedestrian LOS uses density thresholds, as does highway LOS.

Don’t post bullshit!

Hey, those markings and flexposts are already *hardened* daylighting, according to DOT!

It’s not bad to cut and replace a slab. The result looks better than patched asphalt. Concrete is used even for some ramps on asphalt paths because the handmade slopes are cleaner and last long enough to justify up-front costs.

Well, unless you dig the whole thing out and rebuild it yearly

Just roll in backwards

Thanks for the link. I’ll have to read this weekend.

Can you share some of his math-driven case against strip malls?

Do you have a link where he shows his work on the topic?

Do you have a link for any of his good arguments on this topic, *with actual math and numbers?*

As far as I have seen he is just a doomsday prophet

You all are still giving him too much credit. He never understood municipal finance. Their math was always junk.

You think this Supreme Court wouldn’t find a way to kill rent control and keep zoning?

How? This is an example of what happens when local designers think they know better than the MUTCD!

So punishment happens before trial?

The induced demand is the point, David.

**any vehicle that a police officer claims was driven recklessly**

How does a 5-year improvement from 0% to 60% prove that 100% is impossible?

How does that make sense? Doesn’t full robotic operation include speed limiting?

Pretty misleading to cherry pick that part… he expresses a ton of uncertainty about the SUV hypothesis and presents strong evidence against it
