No, and I should have been more clear on that issue list. I didn't expect this post to get much attention and honestly these are just my opinions that I came up with off the top of my head.

What I was trying to get at, is that runners and bicyclists do not stop for traffic lights. I think that's perfectly reasonable at certain parts of the park (north end) where there are few pedestrians crossing. On the south loop, however, there needs to be better mechanisms to control the flow of traffic—both the actual traffic on the loop and the traffic of pedestrians crossing the loop.

The problem I come across often, is that especially during tourist seasons, large groups of pedestrians will stand in the running lanes waiting for the light to change, forcing runners into the cyclist lane. I've seen pedestrians step out in front of runners multiple times, because the pedestrians did not look both ways, and I've seen clueless groups of people walk out into the bicyclist lane in front of traffic, nearly causing damaging accidents with oncoming cyclists.

And this doesn't just happen at the designated crossings. People jump the barriers all the time to get across the park more quickly, but they're now an obstacle that needs to be navigated.

Pedestrian safety certainly requires better control of traffic on the loop, but it also requires that (a subset of certain) pedestrians recognize that the loop is an actively used road with mixed forms of travel.
