Interstate Highways

Interstate Highways Relations

Interstate highways imported from TIGER data need a lot of fixing. It is probably easier to erase a section of the Interstate Highway imported from TIGER data and retrace it over the Yahoo! aerial imagery.

Here are some guidelines to consider:

• Separate interstate direction into two ways. For example, an interstate running West and East will consist of two parallel ways: one running West and the other running East.
• Apply the following tags to every way making up the interstate:
  • highway=motorway
  • name=I-40 East -- a verbose name that includes interstate's direction
  • ref=I 40 -- if more than one highway use the say way combine them using semicolons: ref=I 40;US 1
  • oneway=yes
• When the interstate runs over a bridge, add a way section with bridge=yes
• When the interstate runs through a tunnel, add a way section with tunnel=yes
• For exits leaving the interstate use the following set of tags:
  • highway=motorway_link
  • ref=364 -- reference in this case is the exit number
  • oneway=yes
• For the point at which the exit connects to the freeway, use the following:
  • highway=motorway_junction
  • ref=364 -- reference in this case is the exit number
  • exit_to=West NC 24; Business NC 24; To NC 50; Warsaw -- name should be the connecting roads or exit name as written on the sign, separated by semicolons. See exit list, using NC for state highways, US for national highways, and I for interstates as prefix, and designating the direction of the connecting highway when applicable.
  • name=Mid-County -- Optional exit name. Most exits do not have names. For an example of a named exit: Pennsylvania Turnpike

State Route

Major issues to watch for when editing TIGER data:

• Many exits imported from TIGER data are tagged as highway=motorway_link which is incorrect. They should be retagged as highway=primary_link.
• Direction of many exit ways are also wrong.
• Bridges are not tagged.

State highway attributes:

• • highway=primary
  • name=United States Highway 64 -- a verbose name that includes interstate's direction
  • ref=US 64 -- if more than one highway use the say way combine them using semicolons: ref=I 40;US 1
  • oneway=yes -- when the highway is divided into two ways.
• For exits leaving the highway use the following set of tags:
  • highway=primary_link
  • ref=7 -- only if exits are numbered
  • oneway=yes

Eastern Band of Cherokee Indians

Eastern Band of Cherokee Indians (EBCI) is located in western NC, the Qualla (land trust recognized by US Federal government) consists of 5 counties: Cherokee, Graham, Jackson, Swain and Haywood. Road naming should follow BIA section of US road tagging guideline.

Currently there are two kinds of road numbers:

1. BIA: e.g. BIA-12345
2. FED: e.g. FED-98765

FED- road is sponsored and constructed by Federal-Aid Highway program (FAHP). Please tag FED- road as ref=FED-{number}

Mapping Resources Available

NC Onemap Orthophotography

This is available as an imagery layer in JOSM. In the Outer Banks area, it differs from bing imagery by about 5 meters. I am unsure whether bing or the NC Onemap is offset or both.
