Network analysis using restriction attributes

1113 — Thu, 27 Apr 2023 13:56:03 GMT

Sorry for arcpro in Korean, not English. And I'm not sure if my English writing is correct. I would be grateful if you could understand my situation.

I want to analyze the network using restriction attributes.
I checked the URL below, but I don't know how to write the script.

https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/restriction-attributes.htm#ESRI_SECTION1_15B0E7EC3C6A47FCB4853DE1721A002C

I want to use vbscrpit.
[class1_re] is a text syntax, and I want to classify and use it as follows using attribute values.
The value of "1" is prefer (high), and I want to use this road with low risk in my research.
"2"is an avoid (low), moderate risk less preferred road than 1 and better than 3.

"3" is avoid (high), and it is set as high risk. I want to avoid this road as much as possible.

I want to set Parameters and Evaluator .

As shown in the figure below, in case of avoid(high), should [class1_re] = 3 be set in the field script of evluator?

Or do I need to modify the value of the parameter?

I tried referring to the URL below, but I don't know how to do it because there is no example.

If you have time, any help would be greatly appreciated.

Or, was it wrong to plan in the same way as above?
Should I use cost attributes?

It's not exact, but I set the name of the parameter to the field value, the type to text to fit the field, and I entered the default value of 3, which is the value I set as high risk.

In the case of the evaluator, it is not clear, but it is set as a field name such as edge or junction.

As a result of the analysis, high risk (setting: avoid (high)) was bypassed, and low risk (prefer (high) was analyzed.

If I've misunderstood, please tell me, I'd really appreciate it.
