A worked example
Six points for “Traffic Considerations”
The matrix gave the Collier Center 6 out of 6 on traffic and gave 200 East
Van Buren 4. The two buildings are 0.3 miles apart on the same street
— a six-minute walk.
We measured thirteen destinations across Arizona — the Capitol, Sky Harbor, ASU,
Mill Avenue, Scottsdale, Intel in Chandler, TSMC, Goodyear, Anthem, Prescott, Tucson,
Sedona and Flagstaff. Not one of them differs by more than a mile. 200 EVB
is closer to seven, the Collier Center to four, and two are identical.
What the mileage misses is how you actually get in and out — and there the ACA
scored the worse building higher on all three counts that matter.
Arterial egress. The Collier Center fronts Washington Street, which runs
one-way westbound. Going north, south or east means working through a grid
of one-way streets first. Ask Google to drive you three blocks east along Washington and it
routes you off the street entirely. Van Buren is a two-way arterial: you turn either
direction the moment you leave the garage.
Event-day resilience — the critical failure point. The Collier
Center sits in the immediate blast zone of the Suns arena and Chase Field
— roughly 144 regular-season home dates a year, before a single playoff game, concert
or convention. On those afternoons Washington and Jefferson come to a standstill and
staff are trapped in the parking garages. 200 East Van Buren sits four
blocks north, outside that footprint, with the same drive home whether or not there is a
game.
Freeway proximity. Both look close on a map. Only one is quick: from
Van Buren it is a clean run to the I-10 / 7th Street interchange or straight west to I-17,
while every trip from Washington starts by going the wrong way.
