[Neighbors] Nob Hill seeks your support on Lead and Coal Aves.

[Jim Barrera]

Van,

Such a system can be implemented on the traffic signal control equipment
already installed along Lead/Coal.  There would just need to be some
supplemental detectors at mid-block locations to sense the speeding traffic
far enough from the intersection.  Albuquerque generally uses all one brand
of equipment throughout the City so as to avoid interoperability issues.
It's Econolite out of Anaheim, CA.  There are no traffic signal controller
manufacturers in New Mexico.
