Physical Object: Traffic Management Center
TMC Reversible Lane Management
Overview
'TMC Reversible Lane Management' remotely monitors and controls reversible lanes. It provides an interface to reversible lane field equipment (traffic sensors, surveillance equipment, lane control signals, physical lane access controls, etc.) and to traffic operations personnel to support central monitoring and control of these facilities.
This functional object is included in the "Traffic Management Center" physical object.
This functional object is included in the following service packages:

Requirements
| # | Requirement |
|---|---|
| 01 | The center shall remotely control devices to detect traffic in reversible lanes, including wrong-way vehicles. |
| 02 | The center shall monitor the use of reversible lanes and detect wrong-way vehicles in reversible lanes using sensor and surveillance information, and the current lane control status (which direction the lane is currently operating). |
| 03 | The center shall remotely control automated reversible lane equipment and driver information systems (such as lane control signals) that control traffic in reversible lanes on surface streets. |
| 04 | The center shall remotely control automated reversible lane equipment and driver information systems (such as lane control signals) that control traffic in reversible lanes on freeways. |
| 05 | The center shall collect operational status for the reversible lane field equipment. |
| 06 | The center shall collect fault data for the reversible lane field equipment and send to the maintenance center for repair. |
| 07 | The center shall provide the capability for center personnel to control access and management of reversible lane facilities, including the direction of traffic flow changes during the day, especially between the peak hours and dedication of more lanes to the congestion direction during special events. |
| 08 | The center shall notify traveler information about lane closures or lane reversals associated with one-way convoy operations. |
