Operational Concept

An Operational Concept documents each stakeholder’s current and future roles and responsibilities in the operation of the regional ITS systems. The operational concept documents these roles and responsibilities across a range of transportation services.

AreaDescription
Data ManagementRegional archive data management makes data generated by agency ITS systems available to support planning, analysis, before-after studies, and performance measurement. The Central Willamette Valley archived data management may be supported locally or use the PSU PORTAL data warehouse. Data stored through the archived data management system can be accessed by contributing agencies as well as other users using a web-based interface to support planning and performance measurement functions.
Incident and Emergency ManagementIncident and Emergency Management involves coordinated response to traffic accidents, weather events, disasters, and other localized or widespread disruptions to the regional transportation system. Using ITS technologies, coordinated response and communications, agencies at the state, regional, and local levels detect, respond, and manage incidents and emergencies to promptly restore the transportation system to normal operations. Information sharing between transportation and emergency management agencies includes statewide information and interoperable communication networks to exchange event information, video, and other data to support coordinated management and response.
Public Transportation ManagementPublic Transportation providers in the Central Willamette valley will use Advanced Public Transportation System (APTS) ITS technology to improve and maintain service quality for customers. Coordination among service providers through combined or virtual transit operations systems is particularly important given need for interoperability and customer transfers across the systems. ITS technology will facilitate operational coordination in real time so that passengers can smoothly connect across the system and access transit information across multiple systems. Demand-responsive transit providers leverage electronic reservations and dispatching tools to improve efficiency and vehicle scheduling through the day. Transit providers also work with local traffic agencies to implement Transit Signal Priority at key intersection delay points, improving service reliability under congested conditions.
Traffic Management and OperationsCoordinated regional traffic management and operations facilitates efficient and reliable flow of traffic on regional arterials and freeways in a manner that is responsive to real-time conditions. A 'virtual' traffic management center concept is envisioned to permit sharing of information, and in some cases, device control, among agency participants while minimizing the day-to-day operational staffing requirements. Coordination among agencies permits better management of multi-jurisdictional roadways and parallel facilities using Integrated Corridor Management techniques. Expansion of field ITS devices and increased integration of traffic signals into coordinated central system supports improved timing in response to changing conditions, including incidents.
Traveler InformationAgencies in the Central Willamette Valley provide real-time traveler information on traffic conditions, transit services, and incident/emergency information through shared and integrated ITS systems. With the availability of up-to-date and reliable information, travelers are able to make more informed decisions, reduce travel delays, and make more effective use of the multimodal regional transportation system. Local agencies take advantage of the local agency data entry portal of TripCheck to provide incident and event entry into the statewide traveler information system, including web-based and 511 telephone traveler information tools.
