Cranberry Traffic Management Center
Status: Existing
Description
The Cranberry TMC provides real–time traffic operations support for a large and growing community strategically located at the intersection of I–79, the Pennsylvania Turnpike (I–76), and US–19 in southwestern Butler County. The Township's Traffic Signal Division is responsible for the maintenance and programming of forty–one signals along State and Township roads as well as seven additional signals in adjacent municipalities. Equipment includes traffic cameras/CCTV, coordinated traffic signals, and a dynamic message sign. Services include traffic management, incident detection and response, and sharing roadway status information with other agencies and the media.

Physical Objects
Functional Objects
| Functional Object | Description | User Defined |
|---|
| TMC Basic Surveillance | 'TMC Basic Surveillance' remotely monitors and controls traffic sensor systems and surveillance (e.g., CCTV) equipment, and collects, processes and stores the collected traffic data. Current traffic information and other real–time transportation information is also collected from other centers. The collected information is provided to traffic operations personnel and made available to other centers. | False |
|---|
| TMC Roadway Equipment Monitoring | 'TMC Roadway Equipment Monitoring' monitors the operational status of field equipment and detects failures. It presents field equipment status to Traffic Operations Personnel and reports failures to the Maintenance and Construction Management Center. It tracks the repair or replacement of the failed equipment. The entire range of ITS field equipment may be monitored including sensors (traffic, infrastructure, environmental, security, speed, etc.) and devices (highway advisory radio, dynamic message signs, automated roadway treatment systems, barrier and safeguard systems, cameras, traffic signals and override equipment, ramp meters, beacons, security surveillance equipment, etc.). | False |
|---|
| TMC Signal Control | 'TMC Signal Control' provides the capability for traffic managers to monitor and manage the traffic flow at signalized intersections. This capability includes analyzing and reducing the collected data from traffic surveillance equipment and developing and implementing control plans for signalized intersections. Control plans may be developed and implemented that coordinate signals at many intersections under the domain of a single Traffic Management Center and are responsive to traffic conditions and adapt to support incidents, preemption and priority requests, pedestrian crossing calls, etc. | False |
