You are (or feel) caught in cross traffic.

It occurs because there's no delay between turning red in one direction and green in the cross direction.

1. The light for northbound/southbound Halsted traffic is green.
2. It turns yellow
3. It turns red. Simultaneously the light for eastbound/westbound Cermak turns green.
4. Traffic moves in the cross direction while traffic in the first direction may still be completing its maneuver.

• Adjust the yellow phase to be longer
• Insert delay between RED in one direction and GREEN in cross direction
