Too long
There are no system operation issues that require limiting the length of a segment, but there are a number of reasons that would make things better by limiting the length.
A segment should not have unnecessary junctions, but some two-segment junctions may be present for the following reasons:
- Long roadways or railroads with the city name present will cause a smudged city issue on the city layer.
- Segments that extend outside of an editor's editable area cannot be modified in any way. Keeping roads shorter than 10,000 meters reduces the chances of editors running into more roads with this restriction.
- Long segments require more resources in the client and WME when rendering them on screen.
- At one time there were issues surrounding segments over 10,000 meters. The junction may be present due to this reason alone.
