A few weeks ago we shared with you the new process our team is trying – to go out and observe something random, completely unrelated to healthcare, and try to think about what it would ideally look like if it were meeting Lean principles.
We spent 15 minutes visiting the intersection outside one of our medical centers, then reflected together about what we saw. We asked how do we eliminate waste, increase quality, increase timeliness, decrease resources required, and improve the physical layout of the intersection in pursuit of “no wait and no harm” for passengers and pedestrians using the intersection?
- It takes less than 2 seconds for a car to clear the intersection. However, it takes nearly 10 seconds for a pedestrian to clear the intersection.
- Cars can turn right when the light is red, after stopping first. Pedestrians cannot cross when their light is red.
- Pedestrians batch up in crosswalks when lights are red and it takes longer for pedestrians to cross/clear the intersection. The large batches of pedestrians require cars turning right to wait longer to make turns and clear the intersection.
- The behavior of pedestrians indicate that they cross the street multiple times to avoid shaded and narrow sidewalks to walk in brighter, larger sidewalks, not because they cross to directly reach a destination.
This is what the intersection looks like today:
What if the intersection looked like this?
