City of Phoenix Traffic Signals

[swbrotha100]

I've always wondered why the city of Phoenix installed traffic signals with straight mast arms as opposed to more ADOT type signals, which typically have curved mast arms. Driving around recently, I've noticed a few areas with more ADOT style installations. Some are used for HAWK crossings, and a few more are regular signals.

If you thought Phoenix's traffic signals are odd, check out most of those in Tempe and Goodyear, which are large boxy masts with the traffic signals and street name signs built into them.  There are also a few of those type in northwestern Gilbert.

I like the Tempe/Goodyear style signals. The street names and block numbers are easier to read.
