Roadway Work Zone Traffic Control Equipment Package

Architecture Geographic Scope

Description:

Field elements in a work zone that manage traffic conditions using CCTV cameras and driver information systems (such as DMS) to provide information directly to drivers affected by the work zone activity.

 

Included in:

City of Livingston ITS Field Equipment
City of Lufkin ITS Field Equipment
City of Nacogdoches ITS Field Equipment
County Road and Bridge Field Equipment
Municipal ITS Field Equipment
TxDOT Lufkin District Work Zone Equipment

Functional Requirements:

1The field element shall collect, process, and send work zone images to the center for further analysis and distribution, under center control.
2Under traffic and maintenance center control, the field element shall include driver information systems (such as dynamic messages signs and highway advisory radios) that advise drivers of activity around the work zone through which they are currently passing.
3Under the control of field personnel within maintenance vehicles, the field element shall include driver information systems (such as dynamic messages signs and highway advisory radios) that advise drivers of activity around a work zone through which they are currently passing.
4The field element shall provide operational status for the surveillance (e.g. CCTV) and driver information systems in work zones to the maintenance center.
5The field element shall provide fault data for the surveillance (e.g. CCTV) and driver information systems in work zones to the maintenance center for repair.
