Construction Crew

Consists of three construction technicians

The City of Scottsdale is one of the few remaining cities that build their signals from the "ground up."  It is estimated that the City saves $20,000 per installation of each new signal by using their own crews.

They do it all:

  • build and install new traffic signals
  • install underground conduits and loops
  • install emergency vehicle detection equipment
  • install telephone cable and interconnect wire to new and existing signals
  • provide emergency maintenance

Typically private sector contractors are either construction workers or maintenance technicians.  Scottsdale's construction crews cross train in both positions resulting in more efficient personnel and cost savings to the City.

Traffic Signal

Technology and People

The City of Scottsdale has state of the art electronic equipment and one of the most modern traffic signal intertie systems in the country.  We also have a skilled and versatile staff which enables us to perform more tasks with less people.

Technicians are cross- trained and certified by City staff and the International Municipal Signal Association.

Traffic signals in Scottsdale are controlled by the use of a 170 type microcomputer control system with Wapiti software. 

Scottsdale has also been widely applauded for using "lag" left turns that add to the efficiency of intersections.
