About this file
This is a sole source letter submitted to the Missouri Department of Transportation's Central District by Rhythm Engineering, LLC, confirming the company's exclusive status as the provider of adaptive traffic control systems and related software solutions. The letter, dated July 27, 2026, addresses Robin Warren at MoDOT's Central District and establishes that Rhythm Engineering is the sole manufacturer and provider of the In|Sync adaptive traffic control system, Cyclops real-time detection and data collection hardware, code|GREEN timing plan creation software, and Game|Changer system. These products represent a comprehensive platform designed to detect vehicles, pedestrians, and bicycles while collecting high-definition Automated Traffic Signal Performance Measures (ATSPM) data and automatically generating optimized timing plans for signalized intersections and traffic corridors. The contract period runs from September 1, 2026, through August 31, 2027, with two additional one-year renewal options available. Purchases are to be made on an as-needed basis throughout the contract term.
Rhythm Engineering's exclusive provider status is protected by five United States patents (numbers 8,050,854; 8,103,436; 8,253,592; 8,653,989; and 8,922,392) covering the unique technology and software systems. While code|GREEN is compatible with various video detectors, the company emphasizes that the processor, timing plan creation software, In|Sync adaptive control system, and Game|Changer equipment, along with associated configuration services and adaptive engineering services, are provided exclusively by Rhythm Engineering and no other entity is authorized to distribute these solutions. MoDOT may engage contractors for equipment installation, but all software configuration, maintenance, warranty work, and replacement parts must be sourced directly from Rhythm Engineering. Technical support is available at 913-674-9846.

RE: Rhythm Engineering as the sole provider of In|Sync adaptive traffic control system, Cyclops, the code|GREEN Timing
Plan Creation Software, and Game|Changer.
Rhythm Engineering, LLC provides Cyclops and code|GREEN, the only real-time detection, data collection & timing plan creation system available on the market that – through both hardware and software application – detects vehicles, pedestrians and bicycles, collects high-definition ATSPM data and turning movement counts, allows users to automatically generate timing plans that optimizes signalization both locally and globally, and implement those timing plans into any type of controllers in the field, in just a few minutes. Our unique technology, designed to increase efficiency at signalized intersections and along traffic corridors, is protected by five United States patents: numbers 8,050,854; 8,103,436;
8,253,592; 8,653,989; and 8,922,392.
Rhythm Engineering is the sole manufacturer and provider of the In|Sync adaptive traffic control system, Cyclops, code|GREEN processor and timing plan creation software, and Game|Changer. They are not manufactured, licensed or distributed by any other entity. While code|GREEN is compatible with many video detectors (Cyclops also includes Rhythm
Engineering provided detection), the processor and timing plan creation software is unique. We often work with contractors to install the equipment (rather than agency staff); however, the Cyclops, code|GREEN, and Game|Changer equipment and our associated services, including software configuration and adaptive engineering services, always come directly from
Rhythm.
This letter is to confirm that Rhythm Engineering is the sole provider of the In|Sync adaptive traffic control system, Cyclops, code|GREEN timing plan creation software and its associated configuration services, and Game|Changer, that no other entity is authorized to provide the code|GREEN timing plan creation software and its associated configuration services, In|Sync adaptive traffic control system, or Game|Changer system.
Any questions or if further information is necessary please let me know.
