Abstract:

Access management categories for US and State routes in Chittenden County. Updated from 2002 state access management layer from the Vermont Agency of Transportation ~ “Access Management Program Guidelines” as a reference (See document posted here: <http://www.ccrpcvt.org/transportation/am/>).

Purpose:

Developed for the Vermont Agency of Transportation as part of the Transportation Planning Initiative (TPI) FY-2010 work program, for the permitting approval process of <19 V.S.A. § 1111.> regarding access to State highway right-of-way and in successful completion of Corridor Management Planning. Categories were interpreted using 2008 infrared imagery, Google Maps aerial and street view, and on-ground site inspections.

Supplemental_Information:

Changes from the Chittenden County 2002 data included:

• US 2 in Williston between Old Stage Rd and Telcott Rd.
• US 7 in S. Burlington by I-189.
• US 7 in Shelburne south of Webster Rd.
• VT 15 near Jericho town center.
• VT 15 in Colchester South of Limekiln Rd;
• VT 116 in Hinesburg between Mechanicsville and Commerce St.
• VT 116 in S. Burlington between Woodcrest Rd and Fox Run Ln.
• VT 128 in Westford beween Post Rd and Osgood Hill Rd.
• Addition of VT Route 289 to Essex Town.

Attribute_Accuracy_Value: 1-6

Attribute_Accuracy_Explanation: VTrans Access Management Categories, circa 2003

Logical_Consistency_Report:

Access category data was updated from the 2003 VTrans “accesscategories” layer. The shape file was first cut down to only Chittenden County to make renderings quicker. 2008 infrared imagery (NAIP_1M_CIR_2008) <http://www.vcgi.org/> was then added to the project to see current access on state routes; again this layer was cut to see only Chittenden County in order to keep rendering speeds fairly quick.




The state routes were inspected at a 1:30,000 view through ArcMap initially and a 1:12,000 when closer inspection was needed in developed areas. The VTrans access management guidelines <http://www.ccrpcvt.org/transportation/am/> were used as a guide for determining correct categories for the various segments of road.




Google maps was used when changes to the access category looked necessary from the infrared imagery. Both the aerial and street views were used to check access density and speed limit. If a determination could still not be made site visits were used for proper access category assessments. Site visits looked for posted speed limit changes and distinct changes in the number of accesses of a roadway.




Changes to the “CC_accesscategories_2010″ layer were made by cutting the arcs using the editor feature of ArcMap and changing the attribute PROBABLE_A to the appropriate category numbers 1-6. Also the HIGHWAY_SE, MM_FROM, and MM_TO attributes had to be changed if cuts were made to the “CC_accesscategories_2010″ layer. These attributes are associated with the mile markers on that segment of road, and allow for easier determination of where a segment is located. When cutting the arcs mile markers needed to be divided between the two new segments. The new segments distance had to be found, using Google maps so that the highway_se attribute could be divided properly.
