Miami-Dade County's ATMS Upgrade, Success with Embedded Integrators

The Miami-Dade Public Works Department - Traffic Signals and Signs Division operates and maintains Miami-Dade County’s (MDC’s) traffic-related infrastructure to provide for the safe and efficient flow of pedestrian and vehicular traffic on the arterial street network. Miami-Dade is the most populated county in Florida. It has over 2690 signalized intersections and mid-block crossings; a figure that is increasing by dozens every year and that represents nearly 1% of all signalized intersections in the United States. Several of Miami-Dade County’s primary arterial roadways carry over 100,000 vehicles per day and special signal situations exist such as reversible arterial lanes and Bus Rapid Transit. The MDC Traffic Control Center (TCC) contains one of the country's largest centralized traffic signal control systems. The original system was installed over a ten year period beginning in 1975 and set the standard by which most computerized signal systems were installed throughout the country. Commonly known as Urban Traffic Control Systems (UTCS), it monitored and controlled 2000 traffic signals on all major arterials in MDC for decades. Today, limitations of the existing system include monitoring of only four green phases, low bandwidth communications, much of which was leased, and a central platform over 25 years old. This system is now being replaced with an Advanced Traffic Management System (ATMS) and improvements at all of MDC’s nearly 2800 traffic signals and with the capability to control 4000 signals.The County required a new Advanced Traffic Management System (ATMS) that is a state-of-the-art, distributed architecture traffic signal monitoring and control system. The ATMS objectives were to optimize traffic signal operations at all locations and all times-of-day and also monitor the performance of the signals and automatically notify appropriate staff when a traffic signal malfunctions, enabling staff to respond with maximum efficiency and effectiveness. With Miami-Dade County in the Nation’s top 5 most congested Urban Areas, the ability to oversee and manage the County’s transportation network from a central location, the Traffic Control Center (TCC), was essential for the County’s traffic engineers and maintenance staff to be able to implement traffic signal control patterns in near real-time in response to traffic demands and incidents. The objective of the system was to improve traffic flow by reducing congestion on roadways County-wide as major arterials are coordinated to run more like an integrated network system rather than individual entities.
