<p>Helpful terminology:</p>

<li>ch = contraction hierarchy, for speeding up pathfinding</li>
<li>degenerate intersection = only has 2 roads connected, so why is it an intersection at all?</li>
<li>lc = lane-change (which is modelled very strangely: <a href="https://a-b-street.github.io/docs/tech/trafficsim/discrete_event.html#lane-changing">https://a-b-street.github.io/docs/tech/trafficsim/discrete_event.html#lane-changing</a>)</li>
<li>ltr = left-to-right, the order of lanes for a road</li>
<li>osm = OpenStreetMap</li>
</ul>
<p>Map objects are usually abbreviated in method names:</p>
<ul>
<li>a = area</li>
<li>b = building</li>
<li>tr = transit route</li>
<li>ts = transit stop</li>
<li>i = intersection</li>
<li>l = lane</li>
<li>pl = parking lot</li>
<li>r = road</li>
<li>ss = stop sign</li>
