PTC Traffic Operations Center (PTC Ops Center)

Status: Existing

Description

The Pennsylvania Turnpike Commission's Traffic Operations Center supports safe and efficient travel for the more–than–500,000 daily motorists using the 550–mile Pennsylvania Turnpike System. The Ops Center is located near Harrisburg in Middletown Borough, Dauphin County. The TOC is responsible for traffic management operations including monitoring and controlling traffic and the road network. The Ops Center also coordinates traffic information and control strategies with neighboring agencies, including PennDOT and adjacent states.

The Ops Center monitors traffic operations 24 hours a day / 7 days a week using a network of more than 70 surveillance cameras and loop detectors. There is existing traffic coverage of all interchange areas excepting Beaver Valley / New Castle (as of November 2015). Traffic sensors are focused on the most heavily traveled sections of the Turnpike; coverage continues to expand on a regular basis.

When an emergency situation is identified a staff of more than 50 operators manages incident response through a variety of responders from across the state: nine state police barracks; more than 100 contracted EMS companies; K–9 dogs, life–flight helicopters, and HazMat Teams. Emergency communications (roadside telephones) are provided every 1/10 mile. The center notifies motorists and partners 90 miles in each direction from an accident location or other identified congestion, enabling system users to avoid congestion and traffic backups while preventing secondary collisions.

Future PTC Ops Center participation is anticipated supporting integrated traffic management solutions in several southwestern PA transportation hubs: Cranberry (junction of I–76, I–79, US–19); Monroeville (I–376, I–76 and US–22); and New Stanton (I–70, I–76, and US–119). PennDOT's Western Regional TMC in Collier Twp. and the Cranberry TMC have offered to partner with the PTC Ops Center in developing future regional traffic management strategies.

PennDOT's scheduled conversion to Cashless Tolling technology also offers new possibilities for integrating the Turnpike Mainline into the region's highway grid and local traffic operations. New interchanges along the mainline at closer intervals /key highway locations potentially increase tolled highway usage and supports more–efficient local travel. SPC will initiate a planning study in 2016 to identify possible cost–effective locations. Regional traffic management strategies should be an integral part of any of these planned improvements.
Variable tolling has been raised as a possible future regional traffic management response and strategic opportunity where the Turnpike mainline and regional non–tolled highways are mutually supportive and can be used to good effect in disaster response or emergency management situations. This strategy would be more effective when cashless tolling systems and supportive DMS are in place.

Traveler Information. PTC's standard driver messaging systems, Highway Advisory Radio (HAR) traffic alerts and roadside Dynamic Message Signs, are supplemented by automated telephone services and smartphone applications. There is a voice–activated telephone hotline for travel alerts, 866–976–TRIP (8747). Hands–free, audio traffic advisories can be streamed through the TRIP Talk smartphone app, making equipped customers aware of incidents while assuring that both hands remain on the wheel.

In 2015 the PTC partnered with private technology company WAZE (also a real–time, crowd–sourced navigation app) in the Connected Citizens Program, a program to improve the accuracy, timeliness and availability of roadway and traffic information. WAZE gets real–time live feeds from the Ops Center including incidents, road closures, construction alerts and estimated travel times. Information entered into the app by turnpike motorists (Wazers!) will be viewed and verified through the Ops Center.

Increased app usage is expected to directly improve driver information especially on Turnpike segments not covered by existing PTC sensors. Waze.com also offers a sync–driving feature that displays through a Facebook connection other friends driving to the same destination. WAZE can also coordinate everyone's arrival times when picking up or meeting friends. Featured services such as these are expected to drive a private–sector increase in traveler information that may eventually surpass and supplant public sector travel information services.

Functional Objects

Functional ObjectDescriptionUser Defined
Emergency Data Collection'Emergency Data Collection' collects and stores emergency information that is collected in the course of operations by the Emergency Management Center. This data can be used directly by operations personnel or it can be made available to other data users and archives in the region.False
Emergency Environmental Monitoring'Emergency Environmental Monitoring' collects current and forecast road conditions and surface weather information from a variety of sources. The collected environmental information is monitored and presented to the operator and used to more effectively manage incidents.False
Emergency Incident Command'Emergency Incident Command' provides tactical decision support, resource coordination, and communications integration for Incident Commands that are established by first responders at or near the incident scene to support local management of an incident. It supports communications with public safety, emergency management, transportation, and other allied response agency centers, tracks and maintains resource information, action plans, and the incident command organization itself. Information is shared with agency centers including resource deployment status, hazardous material information, traffic, road, and weather conditions, evacuation advice, and other information that enables emergency or maintenance personnel in the field to implement an effective, safe incident response. It supports the functions and interfaces commonly supported by a mobile command center.False
Emergency Response Management'Emergency Response Management' provides the strategic emergency response capabilities and broad inter–agency interfaces that are implemented for extraordinary incidents and disasters that require response from outside the local community. It provides the functional capabilities and interfaces commonly associated with Emergency Operations Centers. It develops and stores emergency response plans and manages overall coordinated response to emergencies. It monitors real–time information on the state of the regional transportation system including current traffic and road conditions, weather conditions, special event and incident information. It tracks the availability of resources and assists in the appropriate allocation of these resources for a particular emergency response. It also provides coordination between multiple allied agencies before and during emergencies to implement emergency response plans and track progress through the incident. It also coordinates with the public through the Emergency Telecommunication Systems (e.g., Reverse 911). It coordinates with public health systems to provide the most appropriate response for emergencies involving biological or other medical hazards.False
