An aspect of
urbanism that I love is how the land-use pieces fit together in complex but
comprehensive patterns. It’s the
antithesis of drivable suburban development where houses can go in one block,
retail a half-mile down the street, and an office park a couple of miles away.
In urbanism,
the pieces of life can’t be as easily separated, but must live in symbiotic
relationships, whether walkable distances apart or easily connected by
transit. Cars can’t be used as band aids
for ill-conceived land-use patterns.
Because of
the essential connectivity of urbanism, urbanism experts can’t stay in
silos. Unlike drivable suburbia where there
can be shopping center architects, residential architects, traffic engineers,
and other diverse specialties working in near isolation, urbanism experts must
cross boundaries all the time. Urbanism
is more like puzzle-solving, which is way more fun than complying with lists of
rules.
Today’s
example of a multi-faceted urbanist is Jeff Speck. I’ve written often about Speck and his book
“Walkable City”. Through the book, he justifiably
became nationally known on walkability issues.
But
walkability isn’t his only strength.
Indeed, it can’t be. Like every
other urbanism expert, he must have an understanding of the other areas of
urbanism that touch upon his primary area.
Other areas such as transit and traffic capacity.
As a result,
Speck recently spoke before a large conference in Mexico City on the subject of
induced traffic. As always, his
presentation was comfortable, but also profound.
However, you
needn’t take my word for it. You can watch for
yourself. Allow about fifteen minutes. It may be the most insightful fifteen minutes
of your day. Especially if you pay
particular attention to his comments on congestion and how traffic reacts to
it. The fact that traffic adjusts to
maintain the same level of congestion is the heart of induced traffic and why
we can’t build our way out of congestion.
Don’t be
deterred by the Spanish text on the webpage.
Speck speaks in English, although with Spanish subtitles.
Enjoy. And be educated.
As always,
your questions or comments will be appreciated.
