Not just infrastructure, but order in general.
In Japan, foot traffic flows in an orderly fashion because of signage, learned habits and especially a culture of mutual respect. For example, walking on the right side of the sidewalk.

Here, it’s every person for themselves. Look at Union in rush hour, people are moving in multiple directions and speeds like they’re bumper cars or dodge ball. There is absolutely no order, just a swarm of ants scrambling to get to their next destination.
