(uo) create intersection layer

[kfarr]

issue: As a user, I want it to be as easy as possible to rapidly prototype intersections without needing to manually size and position the intersection and all 4 intersecting approaches;

some notes:

• Build from scratch
  • If given 2 existing streets in both direction
  • Place the square of the asphalt and shape in between
• Automagic
  • Dialog box - what is the width of street A, what is width of street B + how many feet beyond roadway is the sidewalk
  • Wizard and/or chat interface to allow users to specify intersection conditions prior to creation
    Sliders to maximize different attributes – ped safety vs. vehicle throughput vs. transit reliability vs. family friendly bike facilities, etc.
• Prefab
  • Create some in advance - top 3 or top 5 designs
  • Protected intersection
    • Have the elements placed in the prefab but with individual elements to allow me to shrink and move the curve / bike lane
• Design issues (high prio)
  • Sidewalk corner
    • Rounded curb
    • 2 curb ramps
    • 1 curb ramp
    • 1 curb ramp
• SYMBOLIC MODEL IS OK
  • Ie curb ramp (yellow truncated domes) representative but not exactly aligned with curb geometry
