Traffic lights cause jams. They worsen congestion by reducing lane
capacity by half. This causes more congestion instead of relieving the
congestion.
When no congestion, lane Capacity is full, but with more traffic, the lights reduce them to half, making the congestion worse, so causing jams.
I wonder why ignored by planners. Not even in textbooks the subject of congestion. Even journals never have a consistent definition of congestion. For drivers, cars not moving is called traffic jam. Not to the civil Engineers because at Traffic lights, cars do not move also.

The solution is simple. Remove all traffic lights but forbid right turns.
To turn right, you must do U-turns. Not difficult in cities because there are lots of buildings. These buildings are huge roundabouts.
One other solution is one-way street. It was proposed by a consultant 10 years ago. Dr. Tan. I didn't support but now I understand why.
