Ohio DOT's Advanced Traffic Management System (ATMS). The ATMS software enables Ohio DOT to monitor and control various ITS field devices from its Statewide Traffic Management Center (TMC) and district offices. The Statewide TMC is located in Columbus at the Ohio DOT Central Office. The Statewide TMC operates traffic management and traveler information systems on Ohio's interstates, freeways, expressways, and state highways in each of the State's major metropolitan areas including Akron/Canton, Cincinnati, Cleveland, Columbus, Dayton/Springfield, and Toledo. TMC operators can control cameras and post traveler information messages to Ohio DOT's DMS, HAR, and to the OHGO website. TMC operators can also act as liaisons between the Safety Patrol Vehicles and various other public agencies that respond to the scenes of vehicle incidents. For redundancy, it is able to remotely operate district traffic management centers. It also communicates with RWIS Roadside Equipment throughout the state. To support CV applications, the Statewide TMC may also include "CV TMC Application Equipment" for centrally generating and digitally signing CV messages (e.g. J2735 MAP, RTCM, and others).
