AVCOG Corridor Regional Analysis and Planning
I have done a couple of corridor studies that had differing purposes and outcomes (to view these go to www.atrcmpo.org/ and select 'Sabattus Interchange Study' and 'Greene Route 202 Study' from the Featured Projects list).
Given my experience, my review of corridor plans from other regional councils and the private sector, and review of what's being done in other states, I think that the model should provide broad guidance but not be so prescriptive that we will be required to include data that may not be relevant to a particular situation. I started to develop an outline with recommendations for a model plan but it would be duplicative of what Tom, Chris, Jay and Josh have already sent to us.
Of the corridor studies I wrote, one focused on ways to improve mobility along a retrograde arterial (Route 202 in Greene) and was presented to the community in graphic format rather than a written report. The value of this format was that the town manager pinned the map to a wall in the lobby of the town office so that everyone can see the full extent of the plan.
The second corridor studied evaluated anticipated impacts on major and minor collector highways from the new turnpike interchange in Sabattus (Exit 86). KVCOG assisted AVCOG with this project because the impacts are expected to affect communities in both regions. Because the ATRC MPO is within the AVCOG region and housed at AVCOG, we are able to do traffic modeling for two of the three counties in our region and have the equipment to do traffic counts and vehicle classifications.
I have looked at state DOT websites for a number of states throughout the country, including Alaska, Colorado, Florida and Vermont. They all have corridor studies which can be reviewed. I found that the studies have the same basic elements but the details differed depending upon the circumstances and conditions of the corridor. The Vermont Agency on Transportation published its Corridor Management Handbook last summer and it's worth reviwing www.aot.state.vt.us/planning/vtcorridor.htm.
I suggest everyone take a look at this handbook. Perhaps the task of developing a model will become easier after looking at what Vermont did.
