always tiny; Dijkstra's is fine. It costs a bit of file size to store
it. The huge leeds map goes from 160MB to 157MB -- not crazy savings,
but something.
Also fix a slight bug with 92d3a890ea that
caused some pedestrians to uselessly visit a bus stop node while
routing. (southbank crashes a few hours in otherwise)
This is simpler to reason about, allows the penalty for entering a zone
or taking an unprotected turn to be expressed in terms of a time
penalty, and is a step towards adjusting bike/foot routing for elevation
data.
When we later add things like "safety/quietness" for cycling, maybe we
can switch to using a (time, quietness) tuple, and transform into a
single number with a linear combination parameterized by that agent's
preference for time/safety. This change is compatible with that future
idea.
There are behavior changes here, particularly for zones and unprotected
turns. No new maps start gridlocking, and in fact, Rainier starts
working again.
"rise / run" calculation used the trimmed road center-lines, which don't
match up with the elevation at each original intersection point.
Also handle infinity in the output and reduce the resolution of the
query from every 1m to every 5m.
Regenerate all maps due to the map format change. Try bringing in
elevation data for all of Seattle using the LIDAR source, since
the data quality assessed in eldang/elevation_lookups#12 seems to be
similar, and LIDAR is way faster than contours.
Regenerate all maps. Gridlock-wise, Rainier and Poundbury broke, but
Wallingford started working again. Acceptable cost for a change this
useful; I'll work on fixing those maps later.
Instead of just picking the intersectin closest to the origin or
destination, calculate the full path length, and take the one with the
shortest distance. This fixes some of the weird problems routing around
Broadmoor. Regenerate all prebaked data.
Also fix the original request for paths involving zones, so tracing it
later works.
wind up looping back on themselves in a nonsensical way, causing
vehicles to visually glitch when moving through.
This was started in 081819d86b, but it
used to gridlock 2 maps. All the recent roundabout fixes seems to have
resolved those! And adjusting offstreet parking for two maps.
But wallingford does regress; plunging forward for now.
intersections. They wind up looping back on themselves in a nonsensical
way, causing vehicles to visually glitch when moving through.
This causes lakeslice and rainier to gridlock, due to the magic of
emergent behavior. I think I upstreamed an OSM fix for lakeslice, but I
need to work on rainier before enabling this code.
attention to which intersection is being destroyed. Fixes#527 --
montlake and phinney both look correct now.
Regenerating everything. Actually, Phinney now runs, so adding a 4th
prebaked map!!! But Rainier regressed -- there's an issue with the
signal heuristics that's now a problem; I'll fix later.
I experimented on the Rainier Valley map, which recently started
gridlocking due to too many cars doing this, to tune the value. Got it
running again! The two other maps keep running, with some trips on
average getting a little slower.
Added an extra step to classify service roads as running through a
parking lot, to prevent them from being treated as regular roads.
Had to fix up a few prebaked traffic signals. lakeslice falls back into
gridlock; will fix separately -- too much effort behind this change to
stop.
be more careful with nodes representing uber-turns. Even if that vehicle
type doesn't use an uber-turn, we still need to force the nodes to exist
and match up between input graphs.
Although this really only fixes gb/charleville_mezieres/secteur4, it
potentially affects all maps, because the node map changes. So
regenerate everything...
City names are now disambiguated by a two-letter country code. This
commit handles almost everything needed to make this transition. Main
next steps are fixing up map edits automatically and making the city
picker UI understand the extra level of hierarchy.
A little bit of fallout: lakeslice gridlocks again; this regression is
actually from the recent traffic signal changes, but I'm just now
regenerating everything. Will fix soon.
- Stop alerting when slow pedestrians can't make it through the minimum
crosswalk time
- Simpler iteration style in lagging_green.rs
- Totally delete the old brute force signal config code; it never worked
well, and the improved heuristics eliminate the need for it anyway
- Make a Duration::max function and use it in one case
* Create module from make/traffic_signals.rs
Most things are in mod.rs, lagging_green and brute_force are moved into their own .rs files
* pull more into brute_force.rs
Add a template for lagging green
Lagging green is variable. Crosswalks are also variable.
convert_to_ped_scramble() is refactored to allow a call that doesn't promote yield to protected; as this could unintentionally extend a variable phase.
This lets you live-tune routing parameters, then see how it affects the
total number of routes that cross every road, relative to the baseline
of the original parameters. We can also use it in the future to do the
same thing, comparing before/after some map edits.
* Skip all-walk if no demand
If you create an all-walk stage and make it adaptive, if there is no demand it will be skipped. Fixed crosswalks are never skipped, as they may be necessary for queue management.
u-turns, but recently, they're forced to left turns if the road names
don't match. Now be more specific and revert either a left or right
turn.
This fixes up https://www.openstreetmap.org/node/53089011, which now
acts like a 4-way intersection for signal heuristics!
Not regenerating everything yet.
