The Transportationist tells me that MnDOT is embarking on a 20-year State Highway Investment planning process (oddly called MNSHIP) and they have one of the better online engagement/feedback collection websites I’ve seen.
The tool lets you choose priorities and then view scenarios or approaches and tells you how each impacts your priorities. Want better Twin Cities mobility? Pavement and bridge condition decline. Want better pavement? Traveler safety might have to lag. It’s dynamic and displays trade-offs clearly.
Of course, all the approaches and impacts are based on the assumption that we don’t really invest more than we are now on transportation in the future, an assumption we should probably discuss if we’re looking 20 years out.
