Daniel YehHOST
In your role in the district, I mean, you've gone in and looked at specific locations and so you have to do that full analysis, like what is safer and less expensive at each location, right?

Sarah TracyGUEST
A lot of times we'll do, and we'll work with Greg and, and his team because they're, you know, the traffic safety and operations experts.

Sarah TracyGUEST
But, uh, we'll work with them or hire a consulting firm, and they'll look at the, the traffic and the safety at that particular location and make a determination on what the best traffic control is at that particular location because it, because it is very context sensitive.

Sarah TracyGUEST
Um, it really depends on where you're at and what's going on with the traffic and the crashes.
