Traffic Signals and Management
Traffic Engineers from the City of Springfield and the Missouri Department of Transportation work side by side in the Transportation Management Center of the Ozarks. This partnership enables local and state traffic professionals to coordinate the two signal systems in the most efficient way possible.

Transportation Management Center of the Ozarks – A Joint Effort
Springfield’s Transportation Management Center (TMC) was established in 1998 by the City of Springfield and Missouri Department of Transportation (MoDOT). Within the TMC, city and state personnel utilize the citywide traffic signal system, real-time traffic monitoring camera system, dynamic message boards (DMS), and other traffic monitoring devices to address changes in traffic flow patterns and respond to incidents that occur throughout the transportation system.
When incidents such as crashes or stalled vehicles occur, TMC operators can relay valuable information to 911 operators. 911 then dispatches emergency response personnel to the scene. Operators dispatch MoDOT Incident Response personal and inform traffic engineers of major incidents so that they can modify signal programming.
City and MoDOT engineers work together to program the signal system with the goal of providing the safest, most efficient operation of traffic signals to serve the motorists and pedestrians. The development of the Transportation Management Center and citywide traffic signal system has enabled both agencies to provide a seamless system across multiple jurisdictional boundaries to improve travel times and reduce stops, overall delay, and fuel consumption throughout the community.
The City of Springfield and MoDOT maintain 271 traffic signals within Springfield, 142 of which are maintained by the City of Springfield. In addition to traffic signals, the agencies also maintain 125 traffic cameras, 48 dynamic message (DMS) boards, and a network infrastructure spanning 138 miles.

Flashing Yellow Arrow
The City of Springfield has begun installing flashing yellow left turn arrows on traffic signals with permissive (yielding) left turning phases. Permissive left turns were previously indicated by “solid green” lights, telling the driver to yield to oncoming traffic. Due to federal mandate, the “solid green” lights may no longer be used for indicating a permissive left turn and must be replaced with flashing yellow arrows. Click for more information regarding flashing yellow arrows.
Coordinated Signal System
The City of Springfield and MoDOT staff work together to coordinate Springfield’s busiest arterials. You can view a map of Springfield’s main coordinated signal network. Signals along these routes are coordinated with each other, as well as with signals along intersecting routes to provide the best possible traffic progression based on regular traffic behavior by time of day and day of week. There are several coordination plans that may be in operation at any given time. Aside from the signals along routes highlighted in the map, signals may be coordinated but are generally programmed to be more responsive to traffic detected at the stop bar. Click here for more information on coordinated signals.
Traffic Signal Installation
The City of Springfield follows the Manual of Uniform Traffic Control Devices (MUTCD), established by the Federal Highway Administration, when evaluating the conditions which may warrant the installation of a traffic signal. These guidelines identify specific vehicular and pedestrian traffic volumes, as well as safety concerns that may warrant the installation of a traffic signal.
Pedestrian Crossings at Intersections
At signalized intersections, the use of pedestrian push buttons may be available with corresponding pedestrian signals to indicate walk and don’t walk times. For more information on the use of pedestrian signals please view the pedestrian safety flyer (PDF).

Intelligent Transportation Systems
ITS technologies improve transportation safety and mobility, reduce environmental impacts, and enhance productivity through the integration of advanced communication-based information and electronic technologies into the transportation infrastructure and vehicles.
Springfield utilizes a combination of Greene County 911’s Computer Aided Dispatch, Advanced Traffic Controllers, Closed Circuit Television Cameras, Dynamic Message Signs, WIFI Sensors, Cell Probe Data (HERE Data), Side-Fire Radar Detection, Automatic Vehicle Location, and Road Weather Information Systems to monitor traffic and road conditions around Southwest Missouri.
The TMC of the Ozarks provides a central hub of communication for these ITS devices. Utilizing over 100 miles of fiber optics, along with 50+ miles of wireless bridges and remote cell communication. Devices from SW Missouri, including Branson, Joplin, Clinton, and Marshfield are tied into our Advanced Traffic Management System (ATMS).
Advanced Traffic Management Systems
TransSuite – A centralized ITS management system that integrates incident /construction information, CCTV cameras, DMS boards, and vehicle detectors. The combination of these data sources allows the operators within the TMC to effectively assist emergency response crews at the scene of incidents, as well as inform the public about traffic issues they are approaching on the roadway.
Transparity – A centralized signal software that allows monitoring and control of signalized intersections in Springfield and throughout Southwest Missouri. Transparity provides both City and MoDOT engineering staff to program and modify signal timing in the field from the TMC as well as notifying our signal shop of communication errors, power outages, and damage to the signal system.
