CHANGELOG

Every time I upload a new binary release, I'll list major changes here.

0.1.0

• First binary release

0.1.1

• drawing arrows better
• start with a splash screen, make it easy to change maps in-game

0.1.2

• totally revamp GUI by organizing everything into distinct gameplay modes

0.1.3

• new warp tool that autocompletes street names
• hideable menus, place context menus better, remove top menu bar, add a simple OSD
• loading screens reflect what's printed to the terminal
• depict pedestrians and bikes with more detail
• tool to scroll through an agent's route
• make simulation speed controls actually work

0.1.4

• improve stop sign editor UI (toggle entire roads)
• better mouseover / selection rendering
• better traffic signal rendering (show time left, use outlines for yields)
• make cars actually stop and briefly wait at stop signs
• improve edit mode diff visualization (cross-hatching)
• render actual stop signs, not just red lines
• fix intersection policies confused by conflicting straight turns with lane-changing
• fix mac scrolling
• better turn indicators
• nicer unzoomed view of roads, with different colors for big/small roads

0.1.5

(release file size jumped from ~15MB to ~70MB because of new PSRC trips)

• improve UX of intersection editors
• define a better set of maps included by default
• improve drawing speed by batching more stuff
• better default traffic signal policies for many cases
• import and visualize census data
• fix missing sidewalks on downtown one-ways
• import and visualize PSRC trip data

0.1.6

• slider widget for controlling time and speed
• fixing bad polyline geometry in most cases; visualizing routes should no longer be buggy
• handle PSRC trips that begin or end out-of-bounds
• draw agents in unzoomed mode in a way simpler way
• improve edit mode: detect reverts to original, easier lane type switching
• lots of fixes for buses: handle edits better, read sequence of stops correctly from GTFS
• set up A/B tests faster

0.1.7

• bulk and revert tools in edit mode
• improve turns and default intersection policies when bike/bus lanes involved
• new tool to manually hint for short roads and weird intersections. some problems have now been manually fixed
• scoreboard of trip results for sandbox and A/B test mode
• reduce lag when sim is running at full speeds, but system is too slow
• switch to easbar's contraction hierarchy crate, making all pathfinding INSANELY fast
• remove weird rules about the world freezing when traffic signals are in "overtime"

0.1.8

• edit mode: convert to a ped scramble cycle, simplify stop sign editor by removing individual turns
• ui: put labels next to sliders, organize modal menus into sections, add a minimize/maximize icon
• A/B test mode: savestate, include time controls and agent following/route tools here
• use more OSM data for turn lanes, turn restrictions from lanes, turn restrictions between entire roads
• dont attempt to cross a traffic signal if there's absolutely no hope
• improve bus route UI tools and make routes using transit more sane
• user-defined shortcuts for jumping between views of a map

0.1.9

• sliders to pick times in wizards
• fix hidpi scaling
• traffic signal diagram scrolls properly
• easier to instantiate a scenario, show all trips involving a building for a scenario
• colorschemes to show trip duration or time blocked
• label buses with route number
• represent overlapping pedestrians as a labeled crowd
• massive performance boost via real priority queue
• prevent cars from "blocking the box"
• prevent all? aborted trips (due to parking blackholes mostly)
• smarter roam-around-for-parking router

0.1.10

• sim
  • parking in off-street garages and on-street lanes on the off-side of oneways now mostly works
  • detect and handle parking blackholes; cars should never get stuck looking for parking now
  • let lower-priority turns happen at traffic signals when higher-priority ones blocked
  • get closer to FCFS ordering at stop signs
  • basic opportunistic lane-changing
  • a bus should be seeded for every route now
• demand data
  • show trips to/from buildings and borders
  • make PSRC trips seed and attempt to use parked cars
• UI
  • different heatmap overlays, like parking availability and busiest areas
  • show colorscheme legends when relevant
  • interactively seed parked cars, spawn more types of trips
  • fix major A/B test mode bug (mismatched scenarios and map edits)
  • adjusting sliders, menu placement, dynamic items
  • consolidating different tools into a single info panel for objects
  • bus route explorer shows entire route, current bus location
• map quality
  • degenerate intersections only have one crosswalk now
  • revamped the map editor for fixing geometry problems, used it in many places
  • nicer yellow center lines (dashed when appropriate)
  • handling OSM turn restriction relations properly
  • fix empty traffic signal phases
  • handling bike lanes on certain sides of the road
  • starting to upstream manually-verified parking lanes into OSM
• new gameplay: reverse direction of lanes
