Included In:

Roadway Subsystem

Market Packages:

• ATMS18-Reversible Lane Management

Functionality:

Functional Requirements*:

1. The field element shall monitor traffic in reversible lanes, including wrong-way vehicles, using sensors and surveillance equipment under center control.
2. The field element shall include automated reversible lane equipment and driver information systems (such as lane control signals) that control traffic in reversible lanes on surface streets, under center control.
3. The field element shall include automated reversible lane equipment and driver information systems (such as lane control signals) that control traffic in reversible lanes on freeways, under center control.
4. The field element shall provide operational status for the reversible lane field equipment to the center.
5. The field element shall provide fault data for the reversible lane field equipment to the center.
