Miami-Dade County to implement smart traffic management technology

Miami-Dade County, Florida, is implementing an advanced traffic management system (ATMS) from Siemens Mobility. The $150m contract will include the upgrade of 2,900 intersections and traffic corridors with intelligent hardware and software technology.

The system will connect intersection technology to an integrated traffic management platform that will perform intelligent analytics, implement strategic measures and optimise travel times across the county.

Traffic patterns

This system will dynamically change traffic patterns in real-time at traffic lights, linking a network of roadway corridors to provide for the better movement of traffic based on actual traffic demand.

Data will be collected in real-time from a wide array of new sources at intersections and roadway zones/corridors, which will then optimise the signal timings at each intersection in a network. This will create an integrated system designed to counteract impending critical situations, as well as unpredictable traffic overloads and congestion.

Siemens’ Sitraffic Concert platform supervises and coordinates the functionality of the ATMS system and it will work directly with the adaptive traffic control system called Scoot (split cycle and offset optimisation technique), a dynamic, online, real-time method of signal control that continuously measures traffic demand on all approaches to intersections.

The fusion of data between the systems will enable a more robust traffic control network. Specifically, traffic data (vehicle counts, travel times) collected by Scoot at the intersection will be utilised within Sitraffic Concert to make network-wide management decisions.

Intelligent traffic management systems significantly increase the ability of municipal authorities to act and allows them to coordinate traffic guidance measures for all modes of transportation

This will allow for operational adjustments to be sent to Scoot for real-time implementation at the intersection, which will ensure public transit vehicles are kept on schedule and pedestrian safety is maximised.

Intelligent traffic management systems significantly increase the ability of municipal authorities to act and allows them to coordinate traffic guidance measures for all modes of transportation. This includes accounting for planned or foreseeable situations such as major events or roadworks, as well as using targeted traffic guidance measures to mitigate unforeseen incidents such as accidents or acute hazards, and respond to them in a quick, efficient and coordinated manner.

The services and technologies Siemens Mobility plans to use in Miami-Dade have been used for traffic systems upgrade projects in more than 300 cities, including recent ATMS projects in Seattle, Delaware, London and Bogota.

Siemens Mobility plans to open a Miami-Dade operations facility and will partner with local small business subcontractors to help facilitate this work.
