I am experiencing odd behavior with side slope transitions throughout a corridor model. The roadway cross slopes work with the super-elevation transitions but when I add a side slope tie in at the edge of the template-either 2:1 of 3:1 cut or fill-the instructions lead to a sudden and abrupt edge in the surface. See the attached photo. Curious to know if other have run into this in the past and what the solution might be.
Are you using Tables with the Sideslope or just a straight sideslope instruction along the length of the corridor? Also are you using a single Template or multiple templates in the corridor.
This could be a Template Transition thing (where one Template says to do one thing and another Template says to do something different so the software tries to morph between the two states - that is the first possibility.
The second possibility is that the sideslope computes at the Computation Interval and at critical points along the road - if at one station it says it is a Cut of 3:1 and the next interval a Fill of 3:1 you will get a transition from one to the other over the computation Interval - this can also be triggered these days by elements prior to the sideslope defined by 2D lines for offset or tables for offset - if you have two nodes very close to each other in the tables, then this will also reflect in the sideslope and if you happen to hit a Cut to Fill transition you could see what you are seeing here.
Failing all of that - I would have to see the model to be able to give you a definitive answer to the question - you can email me at firstname.lastname@example.org if you don't want to share it publicly and I wiull take a look next week for you.
Try changing your computation Interval, try setting densification to Yes on the Corridor Surface Model, take a good look at the instructions and table / line controls at that specific station, and take a good look at the templates defined around that area -that is where I would most likely start - it is hard to tell from the image exactly what is happening at that spot and if it is occurring over a very short distance or a longer distance
If you do share the model - please draw a circle at the station or send me the station and side of the road where the issue is occurring so that I can find it quickly
Alan, thanks for the response. I appreciate the effort. Unfortunately, I have since deleted the slope information from the model to complete the finish grade road surface only.
I have moved to using a single template and tables...this is producing better-more predictable results.
I will be sure to post again if I have issues when I revisit the slopes.
