# TODO - Map quality
|
|
|
|
## Geometry
|
|
|
|
- bad polyline shifting remains... sr176
|
|
|
|
- generalized_trim_back
|
|
- breaks down when we have jagged lane endings due to polyline shift angle correction
|
|
- sometimes a lane polyline hits the perpendicular of a trimmed road! where was this happening?
|
|
|
|
- handle small roads again somehow?
|
|
- VERY overeager... ate half of the map
|
|
- can we capture snapshots of incremental changes?
|
|
- save initial map at every step, be able to load raw + initial with a focus point
|
|
- deal with loop roads
|
|
|
|
- manually draw a picture of the weird intersection to see what would look reasonable. i think we need original road bands from deleted stuff to make decent polygons.
|
|
|
|
- model U-turns
|
|
|
|
- degenerate-2's should only have one crosswalk
|
|
- then make them thinner
|
|
|
|
- ped paths through sidewalk corners are totally broken
|
|
- calculate the better paths first, then make the corner geometry from that?
|
|
- car turns often clip sidewalk corners now
|
|
|
|
- figure out what to do about yellow center lines
|
|
- intersections on one-ways look weird
|
|
- yellow and white lines intersect cars and turn icons and such
|
|
- who should own drawing them?
|
|
|
|
## More data
|
|
|
|
- lanes: https://data-seattlecitygis.opendata.arcgis.com/datasets/49d417979fec452981a068ca078e7070_3
|
|
- not filled out for most streets
|
|
- traffic circles: https://data-seattlecitygis.opendata.arcgis.com/datasets/717b10434d4945658355eba78b66971a_6
|
|
- https://data-seattlecitygis.opendata.arcgis.com/datasets/sidewalks
|
|
- disagrees with OSM road centers sometimes
|
|
- https://data-seattlecitygis.opendata.arcgis.com/datasets/curb-ramps
|
|
- high quality thick roads: https://seattlecitygis.maps.arcgis.com/apps/webappviewer/index.html?id=86cb6824307c4d63b8e180ebcff58ce2
|
|
- OSM has footways
|
|
- but theyre not marked everywhere
|
|
- and theyre hard to associate with roads (sometimes need to infer a planter strip)
|
|
- draw ALL water and greenery areas
|
|
- draw benches, bike racks
|
|
- render trees
|
|
- look for current stop sign priorities
|
|

|
|
|
|
## Low-priority geometry issues
|
|
|
|
- if building front path intersects another building, then scrap that building.
|
|
- or wait, just require bldgs to be even closer to sidewalk first.
|
|
- need to do polygon vs polygon check!
|
|
- will need to speed it up with quadtree containing entire buildings. make sure these are easy to use.
|
|
|
|
- can we make OSM buildings with holes?
|
|
- experiment with https://docs.rs/clipping/0.1.1/clipping/gh/struct.CPolygon.html and https://github.com/21re/rust-geo-booleanop
|
|
|
|
## More problems to fix
|
|
|
|
- Disconnected map
|
|
- Some lane-changing model needed to determine this
|
|
- Impossible turns (from a far bus lane to a crazy left)
|
|
|
|
## Release
|
|
|
|
- publish the map data
|
|
- stabilize the code except for sim
