<h1><a class="header" href="#roadmap" id="roadmap">Roadmap</a></h1>
|
|
<p>A/B Street has been under active development since June 2018. That's a long time
|
|
-- what work is happening now and how can you contribute?</p>
|
|
<h2><a class="header" href="#next-steps-summer-2020" id="next-steps-summer-2020">Next steps, summer 2020</a></h2>
|
|
<p>Afer the alpha launch in June, I plan to focus on:</p>
|
|
<ul>
|
|
<li>shared biking/walking trails like the Burke Gilman</li>
|
|
<li>light rail</li>
|
|
<li>more score functions besides trip time, like safety/comfort</li>
|
|
<li>changing trip mode choice (if you make a bus route more desirable, switch some
|
|
trips)</li>
|
|
<li>web support (so people can try out proposals without installing anything)</li>
|
|
</ul>
|
|
<h2><a class="header" href="#ongoing-work" id="ongoing-work">Ongoing work</a></h2>
|
|
<p>If I had resources to hire a team, this is roughly how I'd organize different
|
|
roles. If you're interested in helping, these aren't strictly defined positions,
|
|
just ideas of related tasks.</p>
|
|
<h3><a class="header" href="#ui-and-data-visualization" id="ui-and-data-visualization">UI and data visualization</a></h3>
|
|
<p>We've got a UX designer, but implementing all of the new designs takes time.
|
|
Also:</p>
|
|
<ul>
|
|
<li>improve color schemes for colorblind players, implement night mode, rain
|
|
effects, etc</li>
|
|
<li>refactor and clean up the GUI library for other Rust users</li>
|
|
<li>lots of data viz design / implementation needed</li>
|
|
</ul>
|
|
<h3><a class="header" href="#game-design" id="game-design">Game design</a></h3>
|
|
<ul>
|
|
<li>the tutorial mode needs attention</li>
|
|
<li>many ideas for challenge/story modes, but playtesting, tuning, and game design
|
|
needed</li>
|
|
</ul>
|
|
<h3><a class="header" href="#map-data--gis" id="map-data--gis">Map data / GIS</a></h3>
|
|
<p>Support more cities:</p>
|
|
<ul>
|
|
<li>write docs/tools to help people add new cities without programming experience</li>
|
|
<li>add support for non-OpenStreetMap input: GeoJSON for parking in Perth, other
|
|
trip demand sources, etc</li>
|
|
<li>fix bugs for driving on the left side of the road</li>
|
|
</ul>
|
|
<p>Improve the quality of map geometry derived from OpenStreetMap:</p>
|
|
<ul>
|
|
<li>try new algorithms to generate intersection polygons</li>
|
|
<li>make tools for easily improving relevant data in OSM</li>
|
|
<li>use ML and lidar/satellite data to get extremely accurate curb / planter /
|
|
sidewalk geometry</li>
|
|
</ul>
|
|
<p>Build tools and organize community mapping:</p>
|
|
<ul>
|
|
<li>organize an effort to map how traffic signals are timed (partly started)</li>
|
|
<li>divide and track work for distributed mapathons</li>
|
|
</ul>
|
|
<p>Bring in new data to understand more about cities:</p>
|
|
<ul>
|
|
<li>PM2.5 pollution</li>
|
|
<li>Tax / land value (is there inequitable access to transit?)</li>
|
|
</ul>
|
|
<h3><a class="header" href="#simulation--modeling" id="simulation--modeling">Simulation / modeling</a></h3>
|
|
<p>Totally new areas:</p>
|
|
<ul>
|
|
<li>light rail</li>
|
|
<li>shared bike/pedestrian paths</li>
|
|
<li>ridesharing</li>
|
|
<li>micromobility (scooters, floating bikeshare)</li>
|
|
<li>more score functions (elevation gain, biking safety)</li>
|
|
<li>generating trip demand / activity models from scratch or modifying existing
|
|
ones</li>
|
|
</ul>
|
|
<p>Improve existing models:</p>
|
|
<ul>
|
|
<li>overtaking / lane-changing</li>
|
|
<li>pedestrian crowds</li>
|
|
<li>instant vehicle acceleration</li>
|
|
<li>pedestrians walking on road shoulders (some streets have no sidewalks)</li>
|
|
<li>buses: transfers, proper schedules, multiple buses per route</li>
|
|
</ul>
|
|
<h3><a class="header" href="#web" id="web">Web</a></h3>
|
|
<p>A/B Street runs on the web via WASM and WebGL; just waiting on vector text
|
|
support. Besides that:</p>
|
|
<ul>
|
|
<li>Share community proposals online, discuss them, vote, etc</li>
|
|
</ul>
|
|
<h2><a class="header" href="#contributing-for-non-programmers" id="contributing-for-non-programmers">Contributing for non-programmers</a></h2>
|
|
<p>There's plenty to do besides programming!</p>
|
|
<ul>
|
|
<li>Mapping, most of which directly contributes to OpenStreetMap:
|
|
<ul>
|
|
<li>sidewalks and crosswalks</li>
|
|
<li><a href="https://dabreegster.github.io/abstreet/map_parking.html">on-street parking</a></li>
|
|
<li><a href="https://docs.google.com/document/d/1Od_7WvBVYsvpY4etRI0sKmYmZnwXMAXcJxVmm8Iwdcg/edit?usp=sharing">traffic signal timing</a></li>
|
|
</ul>
|
|
</li>
|
|
<li>Playtesting by attempting to implement real proposals would also be helpful,
|
|
to expose where it's awkward for A/B Street to edit the map and to write up
|
|
problems encountered.</li>
|
|
<li>Advocacy: I'm not great at finding the right people to to get ideas
|
|
implemented for real. Maybe you are?</li>
|
|
</ul>
|
|
<h2><a class="header" href="#long-term-vision" id="long-term-vision">Long-term vision</a></h2>
|
|
<p>Longer term, I'd like to take lots of the work in generating and interacting
|
|
with high-detail OpenStreetMap-based maps and generalize it, possibly as a new
|
|
OSM viewer/editor.</p>
|
|
<p>More generally, I'd like to see how simulation can help individuals understand
|
|
and explore other policy decisions related to cities. Domains I'm vaguely
|
|
interested in, but not at all knowledgable about, include land-use / zoning,
|
|
housing, and supply chains. In late March 2020, a new collaborator started a
|
|
pandemic model using the existing simulation of people occupying shared spaces.
|
|
What are other domains could benefit from the rich agent-based model we're
|
|
building?</p>
