CHANGELOG

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)

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

0.1.11

small UI fixes: fixed width traffic signal diagram, skip info phase of menus when empty
start drawing (but not using) shared left-turn lanes from OSM
fix OSM polylines with redundant points (fixing an issue in ballard)
improved traffic signal policies in some cases
started upstreaming some sidewalk tags in OSM to fix inference issues
fixed misclassified right turns
adjusting map colors
handling lakes/ocean polygons from OSM way better
reorganized sim analytics, added stuff for bus arrivals
adding new internal road points to map editor. almost ready to really aggressively use it
skipping parking lanes with no nearby sidewalks, since they're unusable
fix z-order of bridges/tunnels in unzoomed view
allow unzooming indefinitely
move lots of sandbox mode controls (and other modes) to menus under buttons and dedicated buttons
basic support for marking a lane closed for construction
improved geometry of sidewalks at dead-ends

0.1.12

reorganize everything as different challenge modes. start implementing 3: optimizing a bus route, speeding up all trips, or causing as much gridlock as possible
improved bus route explorer
some UI fixes (popup messages in a few places, moving mouse tooltips to the OSD)
lots of analytics and time-series plots

0.1.13

analytics: prebake baseline results properly. hover over plot series. some new modes to see bus network, throughput of a road/intersection over time
log scale for the speed slider
add a bulk spawner in freeform mode (F2 on a lane)
rendering: nicer routes, crosswalks, zoomed car colors
map data: better stop sign and sidewalk heuristics
fixed the mac hidpi text rendering issue once and for all?!

0.1.14

better crosswalk generation when there's only a sidewalk on one side of a road

edit mode has proper undo support

0.1.15

minor bugfixes with reverting lane types, preserving stop signs

render pedestrian crowds on building front paths
traffic signals support an offset parameter
traffic signal visualization and editing revamped to group related turns together
can preview traffic using a signal from the editor
actually apply priority at intersections, so protected turns get first dibs over yield turns
