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 Highways

Major issues to watch for when editing TIGER data:

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:

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.
