Minutes:

1. Welcome and Introductions

    Chris Hedden provided an overview of the project, its goals, objectives, and schedule. He also provided a brief summary of what was the goal of these regional interviews with planning and programming stakeholders.

2. Regional Input into the Sketch Planning Process

    We discussed the committees that are currently established which could help further this process. Committees included the Tech Advisory Committee which has in the past been much more operations focused and has not traditionally had a strong presence from planning.

    Other committees includes the SPL and Ops chief’s monthly meetings. These are at central office and have representation from both SPL and Ops from each district. Although ITS/Technology applications have not been the traditional focus of this group either it provides another potential venue to pursue these issues going forward.

    Overall, the region felt that any mechanism by which the regions can have a better understanding of the Operations funding needs, with supporting documentation would be a great help.

They suggested we also talk with NW Region Planning folks Gary Brunner. He is very

    active and could provide a good perspective for the project.

    We next talked about a variety of mechanisms where Operations and ITS could be mainstreamed into the current WisDOT project development processes.

Options include:

Development Review Team. This mechanism is made up of both planning and

    operations personnel at the district level and is usually only created on large scale projects such as the Marquette Interchange project.

Needs Identification Team. Again made up of both planning and freeway operations

    staff. This occurs pre-programming when scoping the problem. It addresses only ITS components not entire systems (i.e. CCTV and DMS). Funded through improvement dollars. Its through this process that Operations/ITS is involved and their needs on specific projects are hopefully integrated early in the process. The projects are typically in the last two years of the six year planning window.

    The Region felt that although this is an effective way to get projects funding it’s a segmented approach and due to the potential long times between adjacent projects a systematic improvement from these devices may be a long time coming.

    Corridor Management A relatively new approach for the department that really combined a number of current processes and procedures under a unified focus. This process feeds off of data provides by SAMP (system access management plan), forecasting from the TDM, and META manager. This process compliments the major program but if a project is major it is not included in this process. They have had early discussion with Operations at central office on how Ops could be integrated into this process. Once possible way would be to look at the SAMP and see how they use this document, perhaps the Ops SPT could be used the same way?

    ITS projects are also funded through the reconstruction program. The SE Region is trying to get ITS needs identified early on in the process. They SE Freeway project currently under design is having Ops needs integrated early. The Region did not get this done early in the Marquette interchange project and see this as a lessons learned. They have been using with good success the ACTT process. This process developed by the feds is really and early VE exercise. A weeklong workshop where all project elements are accessed early in the process.

Rebuilding projects also use this ACTT process.

We next described tools they use for these processes.

    The Freeway System Operation Analysis tool was discussed. The Region seemed to like this process and has had some good success with it. Right now this has only been used in the SE Region but there are discussions to take it statewide. It uses microsimulation (PARAMICS) and develops a detailed model of the study corridor. They have run into some size problems using PARAMICS and very large corridors and are looking at ways to combine it with TDM. So far it has only been used on Mega projects. They run a base year and 2035 year. It is used during the design phase of the project. Forecasts include MPO model and land use data.

    When asked what should the SPT NOT do. The Region answered is should not prolong the time it takes for projects to be developed but work within the current timeframe.

    There was a perception from the Region that in the past Operations did not take the time to explain to the Region’s with programming responsibilities the value of the ITS

    systems and the $ benefit. And the perception was that rather than doing 1 really good project they did 10 with no rationale.

    They thought if Operations was in the LRP it would go a long way to helping the Ops program.
