Map editing guidelines

(or: Let's Just Do This Once), pulled from Colorado To-do pages, and they pulled it from Boston metro To-do pages

Other Items (not listed below)

  • Only split a road into 2 lanes if there is greater than a 20' median, e.g. 2 or more lanes could fit inside. Anything smaller should be a single road, even if there is a physical barrier (this will help with U-Turns, and will make it easier to edit the map in the short and long term).
  • Note that in the old editor, there's also a feature allowing a mid-road line, which may help on roads with a physical barrier but not a lot of lanes.

Interstates/Major/Minor Highways

Due to issues with automatically generating shields on Highways with directionality, it appears to be MOST EFFECTIVE to add directionality, e.g. "I- 70 E" as the first step!

  • eliminate unnecessary junctions: mid-segment, other than where the city changes or speed limit changes, get rid of 'em. (Important exception: don't make segments too long, because traffic analysis is per-segment. Perhaps keep it less than 1km per segment?)
  • confirm lane directionality (note: one-way roads do not have center dividers)
  • connectivity between highway segments
  • road type is correct
  • finalize geometry (remember to preserve Alt Names when changing geometry)
  • naming: preserve TIGER base map naming as requested by Waze (common name, followed by US/State Hwy numbers and other aliases)


  • eliminate unnecessary junctions
  • geometry matches aerials
  • directions correct (note: one-way roads do not have center dividers)
  • road type set to "ramps"
  • street names should match existing signage; e.g.:
    • "Exit 20: Boston / Brighton / Cambridge"
    • "to I-90 W / Worcester"
  • when a ramp segment has no sign of its own (e.g., after two ramps merge), borrow from the names of the "upstream" ramps, which should be similar if not identical
  • check & correct all connectivity among ramps & roads--critical for proper routing

Helpful tip: if a ramp (or any other type of road) segment has no name, the client will display the next non-empty name in line. For example, suppose you have a two-way ramp segment. You can't name it as either an on- and off-ramp, because traffic (and navigation) will be using it for both. The solution is to leave the name blank, which will cause the names of adjoining segments to be displayed.
