TODO

Map editor

• still key overlap bugs with floodfilling

  • master UI exclusive state -- one plugin at a time

• traffic signal editor

  • button to reset intersection to original cycles
  • turns can belong to multiple cycles; the colors become slightly meaningless
  • support left turn yield

• stop sign editor

  • cant have no stop signs for two roads whose center line crosses
    • infer default policy
  • draw as red octogon with thin white trim, off to the right side of the road

• better visualization

  • why are some icons in the intersection?
  • draw detailed turns better, like https://i.ytimg.com/vi/NH6R3RH_ZDY/maxresdefault.jpg

Driving model

• try to simplify straw_model step (less phases?)

• make cars pathfind to their destination

• better visualization

  • draw moving / blocked colors (gradually more red as they wait longer)
  • draw stop buffer in front/behind of cars
  • draw cars in intersections, even when slightly zoomed out
  • draw cars in slightly different colors, to distinguish them better

• start implementing a second AORTAish driving model

• reversible sim

Map model

• more data

  • parse shp, get traffic signals in the right places
  • do need to mouseover shapefile things and see full data
  • grab number of phases from traffic signal shp
  • look for current stop sign priorities
    • https://gis-kingcounty.opendata.arcgis.com/datasets/traffic-signs--sign-point/

• multiple lanes

  • display + mouseover parking lane and sidewalk

    • make the center lines in geom layer work (use debug mode to verify)
    • something broke curved roads
    • make extra lanes for oneways work
      • have to switch from Centered to DrivingDirection somehow
      • either translate points up-front and be normal or fix geom layer (for turns and intersections)

  • model cars parking

    • maybe render numbers on the cars to distinguish them
    • document the FSM (on lane driving, waiting, turning, parking, etc)

  • model bikes in driving lanes (as slow cars)

  • add random bike lanes, figure out how turns would work

  • be able to convert between parking and bike lanes, recompute the turns

  • model pdestrians

    • maybe draw crosswalks?

  • when rendering sidewalks, have an option for a grass buffer

  • regression testing

    • goldenfile approach for map_model, geom, and render layer from a small OSM chunk
    • or maybe a visual demo approach with a list of things to manually check
    • unit test that Centered thick line yields same geometry with points reversed

Code cleanup

• clean up code

  • master Map struct
  • line type / ditch vec2d / settle on types
  • better layering: GeomParcel, GeomIntersection, etc, so that render layer doesn't need to know Bounds and use gps_to_screen

• add/plan tests

• document pieces that're stabilizing

• run clippy everywhere

  • presubmit script
  • also enforce consistent style (import order, extern crate only in mod.rs or lib.rs, derive order)

• extract common crates

• ask about mut vs returning new version of self (and what that requires of all the contained stuff)

  • https://stackoverflow.com/questions/28385339/mutable-self-while-reading-from-owner-object

Example use cases

• montlake/520 turn restrictions with pedestrian scramble
• close interior neighborhoods to most cars (except for src/dst), see how traffic restricted to arterials would work
• create a bike network with minimal hills, dedicated roads, minimal crossings
