In many instances removing or repurposing lanes (road diet) decreases congestion much more effectively than just adding capacity.

Congestion occurs naturally regardless of capacity due to fluctuations in flow (jitter) more often than being over capacity (this is civil engineering 101). By repurposing lanes for dedicated turn lanes, bus lanes, bike lanes, and/or pedestrian walkways, you remove many of the triggers for jitter.

Synchronizing traffic (connected autodrive?) would do much more for removing congestion than just adding high over head capacity.
