									Siemens Eagle Product Program Participation
                               Siemens

• Involved in numerous adaptive
  approaches and strategies
• Recognize need for lower cost
  and easy to install traffic adaptive
  system
• Believe that developing easier to
  use and implement strategy is
  important
                         FHWA

• Recognized need for closed-
  loop environment
• Selected team to contribute
  input on the typical market
• Gathered data from various
  manufacturers
                   Commonality

• Recognized need for
  consistency in installation
  procedures
• Recognized need for
  interactive protocol among
  manufacturers – NTCIP
• Recognized need for minimal
  changes in the field
                    Commonality

• Reviewed controllers and
  data for input to central
• Unit replaces master
  controllers
• Utilizes existing
  communication infrastructure
       Development by Siemens

• Added unique objects and
  formatted for NTCIP
• Siemens traffic control
  firmware developers
  evaluated potential problem
  areas
• Tested for applicability with
  standard traffic control
  methods
                          Beta site

 Determined a lot of applicable
  sites and a lot of interest from
  the users across the country
• Selected a site in Houston,
  Texas, in conjunction with
  Texas Department of
  Transportation
                         Beta site

• Installed in a relatively short
  time frame
• Ease of installation compared
  to other Traffic Adaptive
  systems
      Unanticipated Challenges

• Implementation for phase
  sequence changes
• Controller timing and syncing
  ACS Lite and locals
• Retrofitting of equipment
                      Advantages

•   Many potential users
•   Can run at 9600 baud
•   Requires less detection
•   Works with in-ground loops
    and/or video detection
                  Advantages

• Evaluating with other
  detection methods
• Recommended for corridors
                           Future

• Networking capable
• Facilitation of
  upload/download of control
  data capabilities (timings,
  logs, etc.)
