Figure 31: Connecting an RCTO, a Plan, and an Architecture
This figure shows one of the ways to combine the use of the RCTO and the regional ITS architecture to support planning for operations using an example from the fictitious region of Kesla Valley. The example shows how an RCTO focused on traffic incident management can support planning for operations and in turn, be supported by a regional ITS architecture. In the upper left of the diagram is a box showing the Kesla Valley 2035 Metropolitan Transportation Plan and the operations objectives included in the plan such as "Reduce traveler delay on freeways and major arterials by 5% in 10 years." Below the 2035 plan is an arrow pointing to a box containing the Kelsa Valley TIP 2012-2017. Below the TIP is the Kesla Valley Regional ITS Architecture containing the Traffic Incident Management Service Package. This package contains inventory and stakeholders, operational roles and responsibilities, functional requirements, and interfaces. There is an arrow from the ITS architecture to the TIP showing that the architecture can support the development of the TIP. On the right side of the figure is a box containing the Kesla Valley RCTO for Traffic Incident Management. The RCTO has the following RCTO operations objective: Decrease incident clearance time on freeways and major arterials by 25% in 5 years and potentially other objectives. The RCTO contains an approach which starts out with "Reduce time at each element of TIM including detection and notification of incident with an emphasis on improved coordination across agencies and jurisdictions...(etc.)" The relationships and procedures listed in the RCTO are:
- Develop a regional incident management team
- Hold after-action reviews
- Increase shared knowledge and awareness of roadway conditions across agencies...(etc.)
The physical improvements of the RCTO include, "Implement CCTV sharing between TMCs in Kesla Valley region and 911 call center. Feed State Police CAD data into TMCs." The diagram also indicates that resource arrangements are part of the RCTO.
There is an arrow from the 2035 plan to the RCTO operations objective indicating the influence of the regional plan's operations objectives on the selection of the operations objective for the RCTO. Additionally, there is a two-way arrow between the regional ITS architecture and the RCTO physical improvements indicating a bi-directional flow of information between the two elements.
