for all we know nobody knows

• rewrote the low-traffic neighborhood prototype. neighborhood detection much better, internal streets grouped into traffic cells, two rendering styles for cells. browsing rat runs not ready yet, disabled
• new shared title screen, to switch easily between all A/B Street apps

there's plenty of elbow room down this rabbit hole for some yak-shaving

• new algorithms to find and render city block and neighborhoods. almost ready for use in main applications
• fixed the worst of curb rendering bugs
• new mapbox gl + abstreet demo
• adding command-line --help to most programs

the devil I don't know

• ungap: consolidate editing controls
• workaround some bugs loading map edits
• ungap: add ability to compare a trip before/after some proposed changes
• ungap: make the high-stress metric handle one side of a road missing bike lanes
• ungap route sketcher easier to use when zoomed far out
• ui fixes: units in barrier type, dropdowns focus-fighting with drag-drop cards
• perf: smaller city overview maps

Ungap the Map

• ungap the map bike network tool launched! bike.abstreet.org has documentation and videos
• uploading and sharing proposals now works!
• super speedup to applying map edits

the world burns either way

• bike network tool now shows alternate routes
• small fixes to mode shift and LTN tool
• major internal UI refactors started

Scootadootling about

• incorporated a configurable mode shift and carbon emissions model with the bike network tool
• partially implemented Mara's UX changes to the bike tool
• improved UI map importing: no more overwriting, and naming new maps
• prototyped a new low-traffic neighborhood / rat-run tool

eggplant caveater

• bike network's route tool: naming saved routes, showing details about the route
• switch from s3 to cloudfront CDN; all downloads should be faster
• further pathfinding performance improvements
• fix bike quick sketch tool in left-handed maps
• consolidate tools into a single CLI and include it in the release

and to this very basic emotion, I said something like, "I can do something about that."

• dramatically improve time to recalculate pathfinding
• deploy raw map editor to web, to support a long-form article: https://a-b-street.github.io/docs/tech/map/geometry/index.html
• long-form article about the simulation: https://a-b-street.github.io/docs/tech/trafficsim/discrete_event/index.html
• small fixes to ungap route tool

grass-fed milk

• bike network tool UI fixes, especially for the routing tool
• use drag and drop for traffic signal editor and route waypoints
• small internal map model performance boost
• heavy documentation week

The last guffaw

• releasing a new tool dedicated to planning bike networks!
• massive overhaul to the road editor, including lane cards that can be both dragged AND dropped
• new road labeling in unzoomed mode
• new tool to quickly sketch roads to edit
• new tool to plan routes and see elevation/road types along the way
• load previously saved proposals on web
• disabled prototype: uploading proposals to a central server for easier sharing
