<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>
