TH 61 Visioning and Jurisdictional Transfer Study | Washington County 6Approach and Methodology what types of treatments should be considered to cross the highway and what those treatments would mean for non-motorized delay and level of service. Both current and future transit use will be considered in close coordination with Metropolitan Council, Ramsey County, and other Purple Line staff. Transit needs along the route, as well as station location, will be factored into both the analysis, as necessary, as well as the corridor vision concepts. Traffic Forecasting To best meet corridor needs into the future, we will estimate long-term travel demand in the study area via a review of current planning documents and utilization of the Washington County and Metropolitan Council travel demand models. Previous growth estimates show that traffic volumes along the corridor are generally expected to grow by 5,000 to 10,000 vehicles per day (over 10,000 vehicles per day in the core of Hugo) over the next 20 years, however we will work with our project partners to ensure planning assumptions best reflect up-to-date development expectations. Forecasting will provide future volumes for both 2030 and 2040. Results of the forecasting analysis will be filtered through a sensitivity check to add a layer of robustness to the analysis and forecasting process. The intent of the sensitivity analysis is to consider the impact of different scenarios (increased teleworking, CAV, modal shifts, etc.) on the forecasting and what that could mean to corridor demands. Ultimately the goal of this visioning process will be to understand future potentials and construct a vision that can accommodate the possibilities. This could result in a phased approach which could be influenced through a sensitivity process. Such an approach would take additional time and effort but may yield valuable information given current uncertainties and therefore should be considered prior to finalizing the scope of this section. GOAL DRIVEN—Safety and operational analysis completed with this study will be compared to performance goals derived with project partners through the process. These will help frame the expected result of the vision for intersections and corridor segments alike. Access Blueprint Given the future land use anticipated along this corridor, coming to consensus on access spacing as well as defining primary versus secondary access points is a critical piece of a visioning study. A blueprint map depicting these elements will be created by our team through conversations with project partners considering the various relevant guidelines. As development or changes to the intersecting roadways occur, this plan can serve as the basis for decision making to guide those developments in a way that is compatible with the long-term corridor vision. Our approach to concept scoping is to first define the issues and goals of the vision prior to putting ideas on paper. With Tasks 2, 3, and 4 setting the groundwork for these elements, the overall approach to generating and vetting concepts and developing recommendations is described below. Corridor Concepting When setting a corridor vision, both intersection treatments and segment typical sections in between intersections are key elements to discuss and evaluate during the visioning process. We generally consider this a three-step process:1. Determine typical section alternatives – How many travel lanes are required, how are non-motorized uses accommodated, how do segment needs fit within or impact existing right-of-way, etc.?2. Determine intersection alternatives – Based on the analysis completed in Task 4, what intersection locations require upgraded treatments in terms of traffic control type and lane geometry to best suit the current and future needs of the corridor?3. Create corridor concepts – Combine both segment and intersection elements into various corridor concepts depicting how individual elements can work together to meet corridor goals Define Typical Section Alternatives: Our team will use BeyondTypicals, an interactive typical section tool to develop cross section views along the corridor. These sections can easily be constructed on the fly in a matter of minutes during design workshops and are at a quality level that is easily understood by the public. Check out the video we made for the TH 61 corridor. These typical sections will allow the project team to quickly move from the brainstorming phase to public engagement to get meaningful input on ideas before full corridor concepts are prepared. Define Intersection Alternatives: Based on existing and future operational and safety issues at study intersections, our team will develop a set of potential intersection treatments to analyze. Representative treatment images or drawings will be used to the extent possible to depict the general nature of the intersection design. This process should and will focus on the big picture with respect to various treatments and access management strategies versus getting into detailed intersection geometrics.
