Join Josh Modglin for an in-depth discussion in this video Sight distance, part of InfraWorks 2018 Essential Training.
- [Instructor] In our last exercise, we looked at one of the analysis tools that we can use with Designed Roads, and that was Cut and Fill. But, you also notice that we can compute materials, as well. Let's look at another analysis tool that's available as we design our roadways. So, in our Designed Roadways flyout, we're going to choose, of course, the review and modify roadway designs. This is where we can also see that we can get to that profile view, of any other roads. That traffic simulation shows up here, as well, as mobility simulation.
Let's look at sight distance. And, notice there is a building literally sitting on our roadway. I don't think we'll have that, but it helps identify what's going to happen if sight distance issues occur. So, we're going to select sight distance, and we're going to select this roadway, and we're going to choose stopping sight distance. The direction is forward, we're heading forward, in this direction, and the lane is lane one. And, we'll run an analysis. Notice I have all of the different options checked, and we analyze.
And you notice where the sight pin shows up is right where we have a sight distance issue. And, that this road, you're not going to be able to see around this building, at this location. So, you won't be able to stop in time, for whatever is on this side. So, it not only provides a nice pin, a nice identification, but also colorizes a portion of the lane where there is a sight distance issue. Very easy to identify whether or not we have a sight distance issue on the roadway.
Now, notice again, all of these standards when it comes to our horizontal curve geometry, our vertical curve geometry, and even the stopping, our passing sight distance controls are coming from our design standards. In this case because it's an imperial design, we have AASHTO_Imperial_2011 applied. So, it automatically takes this information, and we don't have a lot of parameters that we have to enter because it's just reading from the design standards.
