Milestone tracking

How usable is each map overall? Different milestones (roughly in order):

• doesn't crash, but gets permanently stuck in gridlock
• full PSRC day finishes without gridlock
  • with freeform policy is usually easier, since traffic signal defaults are quite bad
• full day finishes without any aborted trips
  • enough parking spaces exist
  • parked cars are available when trips need them
  • no disconnected paths
• no geometry problems; map looks reasonble and represents reality
• simulation results match available measurements of reality
  • known vehicle counts for roads
  • example problem: lots of traffic cutting through UW

The different map slices are pretty arbitrary, but roughly get bigger down the list.

montlake

• full PSRC day finishes with traffic signals
• ~300 aborted trips, no free car available

23rd

• full PSRC day doesn't gridlock with freeform policy
  • 23rd and madison traffic signal is the biggest problem, try manual traffic signals

caphill

• short roads at: 12th/union/madison, boylston/roanoke

downtown

• not enough room to even seed parked cars!

lightrail

• uninvestigated crash a while in

ballard

• short roads: aurora/winoa
• uninvestigated crash a while in
• super weird lane geometry near 26th and gilman
  • redundant points in a straight line

huge_seattle

• short roads: lake city, ne 115th
• 12th and ravenna seems stuck, not sure why
• Car with one-step route Router, crash around 6am
