1. Success with Miami-Dade County’s ATMS Upgrade Success with EMBEDDED INTEGRATORS Presented at: ITS America Annual Meeting Houston, Texas May 4th, 2010 by K. K. Saxena, Senior Vice President, Kimley-Horn and Associates, Inc. Jim Reynold, PE, Kimley-Horn and Associates, Inc. Robert Williams, PE PTOE, Miami-Dade County

3. Background In the nineties: 2.2 million Miami-Dade residents logged 42 million vehicle-miles of travel (VMT) over 5,500 miles of arterial roadways in the county By the end of 2000, population and total lane- miles increased by approximately 15%, growth in total Vehicle Miles of Travel (VMT) by 23% An increase in traffic congestion prompted the need to modernize all 2,700 traffic control signals

4. Background Miami-Dade’s Urban Traffic Control System UTCS) Installed mid-70s Funded by FHWA, FDOT, and local bonds Largest central computer control system in the U.S. at inception Reached maximum capacity of 2,048 signals mid-80s

5. Field Alpha Test New timing values and firmware were installed Three two-person teams took roughly eight hours to change-out controllers at 16 locations The field test ran for one month before the top- ranked firm was given clearance to expand control of the intersections

6. Automated Intersection Database Conversion Conduit Verification Prepare Service Order for BellSouth Communications Equipment Procurement (Controller Only) T & S Engineering Verification & Adjustments BellSouth Communications Links Conduit Repair Completed Intersection On-Line & Under ATMS Control LEGEND KHA KHA / TSS TSS Traffic Operations Engineering Contractor TSS Maintenance Bellsouth Controller/Firmware Installed and Tested (TSS Maintenance or Contractor) Equipment Procurement ( Controller Processor Board) Equipment Procurement (Modems) Equipment Procurement (Conflict Monitor) Equipment Procurement (Cabinet/Controller) Miami-Dade ATMS Deployment Steps

7. Embedded Integrators MDC Project Management (2) Contractor Field equipment installation (12) AT&T communications provisioning (6) MDC maintenance & testing teams (18) Contractor Construction engineering and Inspection (20) MDC Timing Engineers (10) MDC System Operators (10) Consultants Imbedded Integrators (3)

9. Embedded Integrator Approach Benefits and Lessons Learned Cost Effective: System Integrator coordinates and guides all work but leverages County resources Excellent training method to all County staff Smooth migration from old to new system Saved deployment time Flexible enough to respond to changing operational needs
