<p>Note: Most of these still aren't started, because the baseline simulation in the
relevant area isn't working. Unknown traffic signal timing, bad guesses at the
amount of off-street parking, lanes tagged incorrectly in OpenStreetMap, and
simulation bugs cause unrealistic gridlock. It's hard to evaluate a change
without a realistic baseline.</p>
<p>In progress:</p>
<ul>
<li><a href="lake_wash.html">Stay Healthy Streets: Lake Washington Blvd</a></li>
<li><a href="west_seattle.html">West Seattle mitigations</a></li>
<li>Simplify where the Burke Gilman crosses Corliss and Pacific
<ul>
<li>No write-up yet, but the proposal is included in A/B Street</li>
</ul>
</li>
</ul>
<p>TODO:</p>
<ul>
<li>Close Broadway and Pine to through-traffic

</li>
<li>Traffic signal timing at Montlake/520 and Montlake/Pacific
<ul>
<li>Walking around here is frustrating, and pre-COVID, vehicle traffic got
fairly stuck</li>
</ul>
</li>
<li>Pedestrianizing the Ave (u-district)
<ul>
<li>I can't find the proposal anymore; maybe
<a href="http://www.udistrictmobility.com/">this</a>?</li>
