There is a traffic light I encounter everyday on my way to work. It’s at a regular four way intersection - streets perfectly perpendicular to one another.
In one direction the street is divided into four lanes, the other into two. It’s not an overly busy intersection however on one side is the entrance to a bus loop making it a hub for pedestrian traffic.
The duration between light changes is interminable and there are long periods where no one moves at all. Drivers receive advance green arrows no matter in which direction they are turning or from where they approach.
All of this waiting while streams of traffic move only in one direction or another makes pedestrians impatient. Instead of waiting for the signal to cross, they’ll cross whenever it appears clear. Often only to become stranded on an island at the centre of the intersection.
The signal sequence makes the flow of traffic unpredictable. On many occasions, I’ve watched as pedestrians get blindsided by vehicles travelling in a direction at a time they didn’t expect.
The intersection is a system burdened by unnecessary complexity.
Which of your systems could benefit from pruning, or paring back to leave a minimum viable offering?
