TODO

mvp strawman sim

• start some tests of savestating + deterministic sim

• cars seemingly whiz past the queue at stop signs (possibly also signals)

• at signals, cars doing the same turn wont start it until the last car finishes it

• draw cars in intersections, even when slightly zoomed out

  • draw cars in slightly different colors, to distinguish them better

• traffic signals

  • parse kml

• draw moving / blocked colors (gradually more red as they wait longer)

• draw stop buffer in front/behind of cars

• cars with different speeds

• clean up code

  • line type
  • ditch vec2d / settle on types
  • split out UI stuff
  • easier way to define magic tuneable constants

if ever stuck

• parked cars
• sidewalks and pedestrians
• reversible sim

editor mode

• make editor mode for traffic signals

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

• stop sign editor (start simple)

  • 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
  • later feature: ban individual turns

• more data

  • shp parser for traffic signals
  • do need to mouseover shapefile things and see full data
  • traffic signal description field says number of phases
  • so many signs: https://gis-kingcounty.opendata.arcgis.com/datasets/traffic-signs--sign-point/
    • all up north? :(

• why are some icons in the intersection?

• support left turn yield

• draw detailed turns better, like https://i.ytimg.com/vi/NH6R3RH_ZDY/maxresdefault.jpg

• mark problem areas where road is too short!

• manually fix OSM issues, like deleting a way completely

cleanup

• add/plan tests
• run clippy everywhere
• 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
• break editor up into more crates
• minimize heap usage -- look into profiling and smallvec
• use some tool to enforce consistent style (import order, extern crate only in mod.rs or lib.rs, derive order)

Conga line idea

• try constructive approach for snake idea
  • with interactive mode?
• try destructive approach for snake idea
  • with interactive mode?
• allow for manual tuning
• serialize results

UI

• support massive maps

  • render to a bitmap and clip that in?
  • drop events sometimes

• draw water and greenery areas

• more toggleable layers

  • show road/bldg types by color
    • can also use to interactively find osm filters to fix
  • show where on-street parking probably is
  • show where sidewalks probably are
    • infer from roads and parcel data?
  • draw benches, bike racks
    • more generally, a way to display random GIS data from seattle site (kml)

• 3D UI sharing the same structure as the 2D one

• web version
