Eg: If we are traveling on I-65 North where it intersects I-40, there will likely be a path to merge onto I-40 Eastbound as well as I-40 Westbound. The I-65 exit for I-40 would contain two Junction objects, one with an
|Highway In State object||The Highway In State that belongs to the |
In the above example, this would contain information for I-40, either East or West, and the state this occurs in (Tennessee).
As shown below in the iExit iOS app, Exits that have non-empty results for
junctions are displayed different than normal Exits.
At the top of this image, you see I-20 intersecting with I-285. This UI allows the user to select I-285 either Northbound or Southbound should the user plan to merge onto I-285.
At the bottom of the image is I-20's intersection with I-75/85. This is an interesting intersection because at this point, I-75 and I-85 are the same road. This is worth noting because iExit treats this as different Junctions. It treats I-75 North different than I-85 North, even though they are the same road at that exact point. This is why there are a total of 5 buttons for this Junction Exit.
