• Miami-Dade County ATMS
• Broward County - TSP

Growth A Boon and a Challenge

• Miami-Dade Countys Growth Trends from 1990 to
  2000
• Population grew by approximately 16
• Roadway lane miles increased by 14
• Vehicle Miles Traveled (VMT) increased by 23

4
Growth Demand for Mobility

• The number of Vehicle Miles Traveled (VMT)
  exceeded both the growth of population and the
  number of lane miles in the last decade
• This increase in VMT is the source of congestion
  on the roadway network

5
Economic Growth Needs Efficient Travel

• Annual delay increased by approximately 17 from
  Year 2000 to 2003.
• TTI ranked the Miami metropolitan area 6th in the
  nation

In February 2005, a poll conducted by
ABC/Time/Post revealed55 of respondents said
that improving traffic signals was an important
remedy

Background

• Miami-Dades Urban Traffic Control System (UTCS)
• First installed in the mid-70s
• Funded by FHWA, FDOT, and local
  Decade-of-Progress bond funds
• Largest central computer control system in the
  U.S. at inception
• Reached maximum capacity of 2,048 signals by the
  mid-80s

8
After the Field Alpha Test Full Deployment

• The completion of the field alpha test in 2006
  cleared the way to proceed with a full
  County-wide deployment of the Miami-Dade ATMS
• Existing 700, outdated NEMA traffic controllers
  to be replaced by Type-170E controllers with
  enhanced processors
• Communication lines and modems are being upgraded
  from voice-grade circuits to 9600 baud digital
  communications
• Approximately 1,180 signals have already been
  converted to the new ATMS

9
After the Field Alpha Test Full Deployment

• The final objective is to migrate the system to
  an ethernet network, which will incorporate
  wireless technology for greater flexibility and
  increase data transfer rates
• Wireless ethernet will also lay the foundation
  for integrating additional devices such as
  wireless closed-circuit television cameras for
  monitoring intersections
