< 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 >
